How to plant zucchini in autumn in cold shed, zucchini planting technology in greenhouse

Hello! If planted in Shenyang, it can be planted according to the local climate conditions and stubble, the temperature is high in the early stage of planting in autumn, disease-resistant varieties can be selected, and the harvest can be started about 30 days after sowing.

In the germination treatment, firstly, the full seeds with early maturity, high yield and strong disease resistance were selected and soaked for germination treatment. Prepare soil, choose humus, sand and peat soil according to the ratio of 2:1:1 mixing, before planting, can apply organic fertilizer at the bottom of the pot; Planting management, planting seedlings into the soil separately, keeping a spacing of 30 to 40 cm; Post-planting management, give enough sunlight time every day, and keep the soil moist with watering.

First of all, select early-maturing, high-yielding and disease-resistant plump seeds, soak them in clean water for a day and a night, let the surface absorb water and expand, and then put them in the substrate for germination treatment, keep them moist after watering on the surface, and germinate in about 7 to 10 days.

Zucchini grows quickly in soil rich in organic matter, and can be mixed with humus, sand and peat soil in a ratio of 2:1:1, and a thin organic fertilizer can be applied to the bottom of the pot before planting, and then the soil can be changed once a year.

The germinated seedlings are planted into the soil, keeping the spacing of each plant at about 30 40 cm, after pouring water, keep the soil moist, if the weather is cold, it can be properly covered with a layer of film to heat up.

When the value is set, it is necessary to give sufficient light time every day, but in the summer, it can be properly shaded, and when 3 or 5 leaves grow, it can be transplanted, and at this time it is necessary to ensure that the water and fertilizer are sufficient to promote growth.

<> greenhouse, zucchini can be planted 20-30 days earlier than cucumber in early spring, and seedlings can be sown from December to January, and planted from late January to early February. After planting, it can generally be marketed in mid to late March, and the seedlings can be pulled in early June. Autumn and winter stubble is generally sown in late August, planted in late September, and harvested in early November.

Zucchini cannot be grown in 80 greenhouses.

Zucchini is at the right temperature

The temperature of the shed should be kept at 25 to 28 during the day, 18 to 20 at night, and when the temperature of the shed exceeds 30 at noon on a sunny day, it can be properly ventilated. After slowing the seedlings, the greenhouse temperature is controlled at 20 to 25 during the day and 12 to 15 at night, which is conducive to the differentiation of female flowers and early sitting melon. After sitting on the melon, keep the temperature to 22 to 26 during the day, 15 to 18 at night, and the minimum is not less than 10, increasing the temperature difference between day and night, which is conducive to nutrient accumulation and the expansion of the melon.

Zucchini cultivation techniques

Fertilization of the land. Mainly organic fertilizer, generally 2000 kg of decomposed organic fertilizer, 75 kg of cake fertilizer, 40 kg of compound fertilizer, and 80 kg of plant ash are generally applied per mu. Spread the fertilizer evenly on the ground, turn it 30 cm deep and level the ground.

Ditching and furrowing. Deep furrows and high furrows are used for cultivation, and plastic film is used to cover cultivation. Generally, the furrow is 100 cm wide, the furrow is 20 cm high, and the furrow is 25 to 30 cm wide.

The furrow surface should be leveled again and herbicide sprayed before capping. When covering the film, it must be tightened and flattened, so that the locust film in the hall is tightly attached to the cover of the furrow, and the surrounding area of the film is compacted with soil. After fertilizing the land as a furrow cover film, use 45% chlorothalonil fumes with 1 kg of fumigation per mu before planting, and close the greenhouse for about 7 days of suffocation.

Colonization. Generally, it is planted in mid-March, and when the seedlings are just 3 leaves, 1 heart or 4 leaves, the seedlings are planted at about 30 days. Small varieties are planted in double rows according to plant spacing of 40 to 40 cm, with about 1800 plants per mu.

Large varieties are planted in double rows according to the plant spacing of 50 to 50 cm, with about 1600 plants per mu. 1 day before planting, the seedbed will be watered thoroughly, select strong seedlings, good seedlings, try to make the roots more with soil transplanting, planting should let the root system stretch normally, after planting watering the roots, and the planting hole with fine soil to cover tightly, after watering 1 time a day, until the seedlings survive.

Fruit preservation. In early spring, when the temperature is low, it is necessary to take artificial pollination, generally before 9 a.m., pick the male flowers that bloom that day, remove the corolla, and gently apply it on the stigma of the female flower. Yu Tsai or use plant hormones such as anti-drop hormone and zagolin to pretend to destroy friends according to the instructions for use.

Fertilizer water. Water according to soil moisture. When there is a shortage of fertilizer in the later stage, 10 to 15 kg of compound fertilizer per mu can be applied or foliar fertilizer can be sprayed.

Harvest. Zucchini is mainly edible tender melon, and is harvested when it meets the requirements of commercial melons. Plants with weak growth should keep less melons and pick melons early.

Do not damage the main vine when picking, and try to leave the melon stalk on the main vine.

Seed treatment is carried out before sowing in order to improve the emergence rate. To do this, expose the seeds to the sun for a few hours, then put them in 60 degrees of warm water, stir for 15 minutes, and then continue to soak for 3 hours. Then, take it out and dry it for 10 minutes, grafting method:

Plugging and docking methods are available. Plugging method: first pick up the two seedlings, remove the true leaves of the black-seeded pumpkin with a bamboo stick, and then jack the hole between the two ** leaves, and then remove the roots of the scion zucchini seedlings, cut the centimeters from the hypocotyl into intervertebral shapes, and water thoroughly to cover the shed.

Watering should be minimized. After sitting on the melon, it should be properly watered, and there is basically no need to water it in winter, only combined with spraying for foliar top dressing. Before the flowering of zucchini, at the melon stage, the area with low fruit temperature can be raised indoors in advance, and the temperature of the seedlings is between 18 degrees and 25 degrees, the specific method is:

In mid-spring or early autumn, use a plastic cup to make a nursery, put two seeds in each nursery, and so after the seedlings are raised, the seedlings are planted to a plant, and then transplanted, the plant spacing between the rows is 60 cm, and the swelling period should be topdressed in time to improve the rate of melon setting, prevent falling flowers, fall melons, and promote fruit development.

The planting soil of zucchini should be loose and soft, sandy soil and clay soil can be planted, and the deeper the soil layer, the easier it is to obtain high yields. So when planting zucchini, be sure to turn the soil loose enough. And add some farm manure to the soil.

The plant grows vigorously, especially in the late fruiting stage, with the increase in the outside temperature, the number of fruits, the burden of the plant increases, the amount of fertilizer needs increases, and the amount of fertilizer can not be too much, so it is necessary to top dressing many times, that is, to master the principle of small amount of fertilization each time and frequent top dressing.

Greenhouse winter and spring stubble zucchini cultivation time is long, plant growth is vigorous, especially in the later stage of fruiting, with the increase in external temperature, the number of fruits, the burden of plants increases, the amount of fertilizer increases, and the amount of fertilizer can not be too much, so it is necessary to top dressing many times, that is, to master a small amount of fertilizer each time the insect pest will be more serious, and then apply sufficient base fertilizer to him. If you use about 3,000 kilograms of organic fertilizer for one acre of land, turn it evenly, and close the greenhouse half a month in advance, so that the soil temperature can be increased, which is more conducive to the growth of seedlings.

If you want to grow zucchini in a greenhouse, you need to give the zucchini enough nutrients, apply enough fertilizer, and maintain a suitable temperature.

First of all, when planting, we must choose the land with relatively fertile and wide soil, and in the process of fertilization, we must use farmhouse fertilizer, do not use fertilizer bought outside, and often water the plants more, to prevent the occurrence of insect pests, if there is a situation of small insects, then we must spray insecticides in time.

First of all, choose excellent varieties, followed by reasonable dense planting, and then maintain the temperature in the greenhouse.

It is best to choose high-quality zucchini that is early ripening and resistant to low temperatures, such as Jinghu No. 3, etc. 3. Planting: After the zucchini seeds are soaked and germinated, they can be sown into the fertile soil.

4. Temperature: Adjust the temperature of the greenhouse to about 25 degrees to promote the rapid germination of zucchini.

1. Planting time

When planting zucchini in a greenhouse, it is best to choose to sow from mid-November to early December every year, so that the plants can mature quickly, and the land should be plowed to remove stones and clods in the soil, and then apply rotten organic fertilizer and farmhouse fertilizer to the soil, which is conducive to the vigorous growth of zucchini.

2. Select the variety

When planting zucchini, you need to choose early-maturing and low-temperature tolerant high-quality varieties, such as Xianghu No. 1, Jinghu No. 6, Cuihu No. 22, Jinghu No. 3, etc., and then put the seeds of zucchini into the water, and then remove the shriveled and damaged seeds floating on the water surface to increase the germination rate of zucchini.

3. Planting method

When sowing and propagating zucchini, the seeds need to be soaked in warm water at 45 degrees for 24 hours to allow them to absorb enough water, and then the zucchini seeds are placed in an environment with a temperature of about 27 degrees for germination, and then they can be sown into the soil and covered with a layer of mulch film to promote the rapid emergence of zucchini.

4. Maintenance management

When curing zucchini in the greenhouse, it is necessary to adjust the temperature during the day to about 25 degrees, and control the temperature at night at about 20 degrees to provide the most suitable environment for the growth of zucchini.

When planting zucchini <>, the ground temperature is required to be stable above 11-13, and the temperature at night is not lower than 0-2. During the growth and development period, the suitable daytime temperature is about 18-26, and the suitable night temperature is about 12-15.

1. The West Lake is suitable for planting temperature

1. When transplanting and planting zucchini, the ground temperature is required to be stable at more than 11-13, and the night temperature should not be lower than 0-2.

2. If it is planted in a greenhouse in autumn and winter, the seedlings are generally raised from late August to early September, planted from late September to early October, and harvested from mid-November to January of the following year. If it is planted in a greenhouse, seedlings are generally raised in early October, planted in early November, and harvested from New Year's Day to May. If it is planted in a greenhouse in early spring, seedlings are generally raised in mid-January, planted in mid-to-late February, and harvested from April to July.

If it is planted in a spring greenhouse, the seedlings are generally raised in mid-February, planted in late March, and harvested from May to July.

Second, zucchini is suitable for growth temperature

1. The suitable temperature for the growth and development of zucchini during the day is 18-26, and the suitable temperature for growth and development at night is 12-15. When the temperature is below 15, the growth rate is slow. When the temperature is lower than 8, the growth basically stops.

When the temperature is above 30, the growth rate is slow and it is susceptible to disease. When the temperature is higher than 40, the growth basically stops.

2. The suitable temperature for seed germination is 25-30. When the temperature is around 13, germination is extremely slow. When the temperature is 30-35, the germination rate is fast, but it is easy to grow.

3. After sowing and before emergence, the temperature is controlled at about 25-30 during the day, about 18-20 at night, and about 22-24% at ground. After the seedlings emerge, the temperature of Acacia is controlled at about 25 in the sky and 13-14 at night (after the first true leaves, the temperature is reduced to 12 at night). 8-10 days before planting, the seedlings are refined, and the temperature is controlled at about 15-25 during the day and 6-10 at night.

4. During the flowering and fruiting period, the temperature is controlled at about 22-25, and when the temperature is lower than 15, the pollination is poor. When the temperature is higher than 32, the flowers can not grow and develop normally, and it is easy to drop flowers and fruits or unisexual lead buried in the stove to set fruit.

5. The suitable temperature range for the growth of pollinated fruits is about 18-25.

6. The suitable temperature for root growth is 25-28, the minimum temperature for root growth is 6-8, and the minimum temperature for root hair growth is about 12.

Winter zucchini planting tips, so that the planting yield is high and there are few insect pests, and it can bear fruit for 2 months at a time.
