What is the specific process of cucumber cultivation technology scheme?

1. Soil selection and land preparation Choose a clayey sandy loam soil with pH in between, rich in organic matter, good drainage and irrigation, water and fertilizer retention, and avoid continuous cropping with melon crops, and the best stubble is paddy field. The land preparation adopts deep furrow and high furrow, furrow width meter (even ditch), furrow height of 30 cm, north-south direction, double row planting, plant spacing of 30 cm.

2. Sowing seedlings in early spring 1 and 3 months, summer and autumn planting 6 August. Spring sowing is soaking and germination after seedling raising or mulching and direct seeding, and summer and autumn soaking and seeding or dry seed direct seeding can be used.

Soaking seeds and promoting germination is widely used in cucumber sowing, blanching and sterilizing seeds with 50-55 warm boiled water for 10 minutes, stirring constantly to prevent scalding. Then soak it in warm water for about 30 -6 hours, scrub it clean, drain it, moisturize and promote germination in an incubator or warm place at 28-30 hours, and start germination in 20 hours. In early spring, small arch shed insulation seedlings, seedlings with seedling cups or seedbeds, seedlings aged 15-20 days (2 true leaves) when planting, in the evening of sunny days, pay attention to protect the root system, drenched before seedlings, seedlings in order, do planting with soil, in order to prevent root damage.

3. Fertilizer and water management and soil cultivation Applying sufficient basal fertilizer is one of the keys to stable and high yield. Cucumber responds well to base fertilizer, deep ploughing and increasing decomposing organic fertilizer during land preparation, 2000 kg -3000 kg per mu, 50 kg of gross fertilizer, and 30 kg of superphosphate as base fertilizer. When the plant has 2-3 true leaves, start topdressing.

The absorption capacity of cucumber roots is weak, and it is sensitive to high concentration fertilizers"Diligent and thin"As a principle, top dressing is done once every 6-8 days, and 5 kg to 6 kg of urea per mu is applied.

When the tendrils appear, combined with cultivating weeding and soil fertilization, after harvesting the first batch of melons, the soil is fertilized once, and 15 kg to 20 kg of peanut bran, 30 kg of compound fertilizer and 10 kg of potassium fertilizer are applied per mu. In summer and autumn, due to the high temperature, rapid growth and development, fast aging, coupled with the large amount of rainfall, the loss of fertilizer and water is more, in addition to the application of sufficient base fertilizer, it is necessary to top dressing early. At the stage of 1-2 true leaves and after harvesting the first batch of melons, the soil should be fertilized once, and phosphorus and potassium fertilizers should be paid attention to to avoid steep growth and premature aging.

The water should be controlled at the seedling stage of spring cucumbers. The flowering and fruiting period requires the most water, and it is generally watered once a day on sunny days and once a day in 3-5 days in dry conditions. In rainy days, it is necessary to do a good job of flood prevention.

4. Erection and pruning Generally, when tendrils appear, insert bamboo and erect a frame to lead vines"Herringbone racks"。Vine introduction begins after the tendrils appear, and is done every 3-4 days to evenly distribute the plants, and is carried out in the evening on a sunny day. Whether the cucumber is pruned depends on the variety, and the main vine bears fruit generally does not need to be pruned; The main side vine bears fruit or the side vine bears fruit, to pick the top and prune, generally the side vines below 8 nodes are all cut off, and the side branches above 9 nodes are left with 3 knots after the top, and the main vine is about 30 sections to pick the top.

Cucumber cultivation techniques are as follows:

1. Seed treatment: cucumber planting technology needs to be treated with seeds first, placed in warm water at 25 degrees for soaking for 6 hours, washing off the dirty substances on the surface, and then taking out the seeds with a damp cloth and placing them in the environment of 25 for germination, and then taking them out for sowing after one day.

2. Soil selection: You can choose nutrient-rich humus soil for planting cucumbers, or you can choose 2 parts of vegetable garden soil and 1 part of fully burned cinder to prepare the soil, and add some gravel or corroded pine to the soil in the later stage, which can play a moisturizing effect and make water not easy to lose.

3. Sowing: Dig a hole the size of an index finger in the soil, then place the seeds 2 cm deep, then cover the soil and water until the soil is moist, place it in a diffuse and ventilated place, and wait for about 3 days for the cucumber to take root and sprout.

4. Watering: during the germination of cucumbers, do not water, wait for the emergence of seedlings can be watered in an appropriate amount, in the growth period of cucumbers, you need to water every 3 days or so, try not to water during the flowering period, you can water every 7 days or so, if the soil is seriously cracked, you need to water in advance.

The cultivation technology of cucumber is not much different from other melon planting, and you can eat sweet cucumber by controlling the five points of seed, ground, water, fertilizer and frame.

1. Land selection and land preparation

The pH of the soil suitable for growing cucumbers should be controlled. The soil should be rich in humus, normal drainage and irrigation, and strong moisture retention capacity. The previous crop of the soil should not be melon crops to avoid the harm of soil-borne diseases.

After selecting the land, do a good job of land preparation, and it is advisable to cultivate high furrows and deep furrows. Turn the soil deep about 30 cm, keep the height and width at about two meters, the depth of meters, and the length according to the actual situation. Then apply sufficient basal fertilizer and stir well with the soil to improve the fertility of the soil.

2. Sow seeds and raise seedlings

Cucumber should first be soaked and germinated before sowing. First, blanch the cucumber seeds with warm water at 50 degrees, stir the seeds constantly during the blanching to avoid the seeds being scalded, and remove them after about 10 minutes.

Then soak in water at 30 degrees Celsius for about 5 hours. Then remove and drain the water, wrap it in a damp cloth and place it in 30 degrees of water for germination.

The seeds will germinate after about a day, and the seedlings are mainly raised in small arched sheds in the seedbed. The seedlings are planted about 2-3 weeks old. It is advisable to plant with soil to avoid injuring the roots of seedlings.

3. Fertilizer and water management

Before planting, we need to apply sufficient base fertilizer, which is the key to ensuring the yield of cucumbers. In land preparation, about 2500kg of farmhouse fertilizer is applied per mu, with an appropriate amount of gross fertilizer and superphosphate.

When the plant has grown about two true leaves, the first fertilization is carried out. Because the root absorption capacity of cucumbers is relatively poor, fertilization should be mainly applied more and a small amount.

Top dressing is about once a week, and each fertilizer is mainly urea, and the dosage is controlled at about 5kg. In the seedling stage, the water should be controlled, the flowering and fruiting stage should be increased appropriately, and the watering frequency should be reasonably controlled according to the weather. Water once a day on sunny days and drain water on rainy days.

4. Set up a frame to lead the vines

Cucumber is a creeping plant, so when we plant, we must also do a good job of building a frame to attract vines. When the tendrils of cucumber plants appear, it is necessary to start to build a frame, which is mainly a herringbone frame, and the vine introduction work is done about once every 3 days.

When introducing vines, it is necessary to ensure that the branches of the plants are evenly distributed on the support, which should be carried out in the evening on a sunny day. According to the variety of cucumber, do a good job of pruning, if the main vine bears fruit, then generally do not need to prune. If the side vines bear a lot of fruit, then pluck the tops and prune.

Be sure to use loose, fertile soil.

Cucumber cultivation techniques involve the use of loose and fertile soil, and deep ploughing of the soil. Sprinkle cucumber seeds, cover with a centimeter of fine soil, and water the soil with spraying to keep the soil moist. When the cucumber seedlings grow to two or three leaves, transplant them with soil, and fertilize the cucumbers in time to remove insects.

Remember to add farmyard manure and compound fertilizer to the soil to keep it fertile.

The temperature of cucumbers is controlled above 25 degrees during the growing period, especially in the spring when the temperature is relatively low at night, so it is necessary to cover the seedlings with a straw mat. When the cucumber seedlings have grown to two or three leaves, they should be transplanted, and the finished seedlings should be moved to the field with soil and given sufficient light. The planted cucumber seedlings should be checked in time, weeded the cucumber and loosen the soil.

The amount of fertilizer should be determined according to the length of cucumber seedlings, and the amount of fertilizer should be gradually increased. Finally, in the process of cucumber growth, pesticides can be sprayed to avoid insect pests.

What to do if the cucumber flower is topped

Causes: drought and lack of water, squatting seedlings too ruthlessly, insufficient water and fertilizer, will cause plant growth stagnation; When the temperature is low, the growth of plants is inhibited when the nutrients produced by photosynthesis during the day are not enough to the growth point at night. The soil temperature is low, the cucumber root system is underdeveloped, and the nutrients in the soil cannot be fully absorbed for photosynthesis. Excessive fertilization can cause root damage.

Prevention and control methods: should not use excessive water; The minimum temperature of the shed at night should not be lower than 13, should be kept at 15 18, and the temperature during the day should be controlled at 28 30; Do not exceed the standard for top dressing, avoid burning and hurting roots, try to use hormone drugs and foliar fertilizer as little as possible, and strictly control the concentration when hormone drugs are needed (ethephon, chlormequatin); It can be sprayed on the foliar surface with agricultural rare earth elements and diabetes urine.

Cucumber cultivation techniques include environmental selection, land preparation and fertilization, seed treatment, planting, and cucumber seedling transplanting.

1. Environmental selection

Cucumbers belong to the crops that love the warm environment of Hongda and do not resist ground temperature. It is suitable for growth and development temperature around 18 32, when the temperature is less than 10, it is easy to be frost damaged and affect the growth and development, when the ground temperature is less than 12, the growth of rhizomes will be limited, the general ground temperature is about 15 and is more beneficial to the growth and development of rhizomes, farmers can clarify the transplanting time of cucumbers in accordance with this temperature regulation.

2. Soil preparation and fertilization

After selecting the cucumber planting land, organic fertilizer and organic fertilizer should be applied in a certain amount, and then balanced fertilization Xunxiao, the most important chemical fertilizer includes well-rotted organic fertilizer, urea, calcium, potassium fertilizer, to ensure that the chemical fertilizer and soil are integrated, and farmers should pay attention to ridge formation, fully prepared for planting.

3. Seed treatment

Cucumber cultivation technology must first be treated with seeds, placed in 25 warm boiled water for more than 6 hours of soaking, wash off the surface of the dirty substance, and then remove the seeds with a wet rag, placed in the environment of 25 acres to carry out mu containing tooth stimulation, one day later can be removed to start planting.

4. Colonization

Before planting, apply appropriate pesticide fungicides to sterilize the land, ditch and irrigate on the ridge, and then cast seedlings according to the effective interval, seal the ditch after water infiltration, plant 3,500 plants up and down 1 acre, and buckle the small arch shed on the furrow after planting.

5. Transplanting cucumber seedlings

When the ground temperature is maintained at about 15, you can start transplanting seedlings, carry out ultra-low temperature seedlings for more than 10 days before transplanting seedlings, select sunny days in the morning or after 4 o'clock in the afternoon to carry out transplanting, transplanting is best Kakashi transplanting, and carry out standardized management of seedlings to ensure that the seedling emergence rate in the field is consistent.

Treat the seeds: Soak the cucumber seeds in warm water and wrap them in a damp towel for 1 day. Sowing seeds into the soil:

Seeds are sprinkled in the soil and covered with soil and watered, and germination will occur in 3 days. Water and fertilizer management: During the growth of cucumbers, water once every 3 days.

Scaffolding: Build a scaffolding so that the branches and leaves grow along the shelf.

1. Treat the seeds

Cucumber seeds have a continental core draft layer of seed shell, poor water permeability, in order to improve the germination rate, before sowing to carry out germination treatment, soak it in warm water for 6 hours, and then clean the surface of the substance, wrap it in a wet towel, placed in the environment of 25, 1 day later take out the seeding.

2. Sow seeds into the soil

Choose loose, breathable, humus-rich soil for planting, or use garden soil and cinder mixture, add gravel to moisturize, and then sprinkle cucumber seeds into the soil, cover the soil and water, generally 3 days to take root and sprout.

3. Water and fertilizer management

Cucumber in the germination period, should not be watered, wait until the seedlings unearthed after watering 1 time, during the growth period, every 3 days watering 1 water, flowering every 1 week watering early filial piety, fertilization is mainly based on organic fertilizer and base fertilizer, supplemented by chemical fertilizer or top dressing.

4. Set up a frame to lead the vines

When the cucumber seedlings grow to a certain height, it is necessary to build a scaffold, let the branches and leaves grow along the shelf, to avoid the situation of chaotic growth, in addition, after 1 month of planting, carry out topping, remove the top heart leaves, and prune dead branches and diseased branches at the same time.

Apply well-rotted farmhouse manure to the fertile soil and mix well. Planting: Place 1-2 melon seedlings in each hole.

Breeding management: keep the temperature above 15 degrees Celsius, and tie vines after planting.

1. Melon seed germination

Cucumber seeds are wrapped in a hard and smooth shell, and the inner bud head is difficult to break, so before sowing, it is necessary to file a small hole on its surface, then soak the seeds in warm water at 25 degrees Celsius for 4 hours, and then put them in an environment at room temperature 25 degrees Celsius to induce germination.

2. Organize the plot

Cucumber has certain requirements for the soil, in the planting process to choose a fertile plot, apply the rotten farmhouse fertilizer as the base fertilizer, the amount per mu is 1000 catties, and then use the agricultural machine to turn the soil and the rotting fertilizer evenly, and put it in the strong sun to white.

3. Carry out planting

Cucumbers are generally dug holes and sowed, the interval between the holes is about 30 cm, each hole puts 1-2 melon seedlings, watered once after planting, and the distance between the sidewalks is about rice, so as to facilitate the later construction of melon sheds.

4. Breeding management

The temperature of the soil where the cucumber seedlings are located should be stable at about 20-25 degrees Celsius during the day, and the lowest temperature at night should not be lower than 15 degrees Celsius.

Summary. 1. Environmental selection Cucumbers are crops that prefer a warm environment and are not tolerant to ground temperature. Its optimal growth temperature is about 18 32, when the temperature is lower than 10, it is easy to suffer from cold damage and affect the growth, the growth of the root system will be limited when the ground temperature is lower than 12, and the general ground temperature is more favorable to its root growth when it is above 15, and the farmers can determine the transplanting time of cucumber according to this temperature requirement.

Cucumber belongs to shallow root plants, its absorption capacity of water and fertilizer in the soil is not strong, and the ability to retain water and fertilizer is weak, so cucumber has higher requirements for water and fertilizer in the growth process, and the growth period of cucumber is relatively long, therefore, before transplanting cucumber, it is necessary to ensure that the bottom fertilizer is sufficient. According to the root characteristics of cucumbers, it is best to choose plots with moderate soil viscosity and good water and fertilizer retention ability when transplanting.

Cucumber belongs to shallow root plants, its absorption capacity of water and fertilizer in the soil is not strong, and the ability to retain water and fertilizer is weak, so cucumber has higher requirements for water and fertilizer in the growth process, and the growth period of cucumber is relatively long, therefore, before transplanting cucumber, it is necessary to protect the bottom fertilizer of celery rent.

According to the root characteristics of cucumbers, it is best to choose plots with moderate soil viscosity and good water and fertilizer retention ability when transplanting.

2. Soil preparation and fertilization Cucumber seedlings are transplanted about 10 days ago, first of all, sufficient basal fertilizer should be applied, generally speaking, the basal fertilizer is mainly based on the well-rotted agricultural residue and household fertilizer, with the application of nitrogen, phosphorus and potassium fertilizer. Rotted cake fertilizer generally needs to be applied about 100 kg per mu, with the application of 20 kg of hungry potassium sulfate fertilizer and an appropriate amount of compound fertilizer. After fertilization, carry out deep ploughing and fine raking, mix the fertilizer evenly, water thoroughly before transplanting, and carry out ridge making after the moisture vertical slag is suitable.

3. Cucumber seedling transplanting when the ground temperature is stable above 15 can be transplanted, transplanting seedlings before carrying out low temperature and void Kai refining seedlings for about 10 days, choose to transplant in the morning or after 4 o'clock in the afternoon on a sunny day, it is best to transplant with soil when transplanting, and classify the seedlings to ensure that the uniformity of the seedlings in the field is consistent. 4. Water and fertilizer management After transplanting, if the base fertilizer is sufficient and the moisture is good, there is no need to carry out water and fertilizer cultivation and supplementation, as long as the soil is kept dry and wet. When the root melon grows to more than 10 cm, you can carry out the first watering, generally speaking, the cucumber is watered once a week before harvesting, watered once every 4 days during the peak period of melon picking, and watered once a week in the later period.

Combined with watering and melon picking, urea and potassium sulfate fertilizer were applied once every half month in the early stage of melon picking, and the fertilizer was topdressed every 10 days during the peak period. The peak period of cucumber fertilizer demand is basically in the peak fruiting period, so it is necessary to reasonably manage water and fertilizer according to the law of fertilizer demand to ensure high yield and income of cucumber.
