What is the cultivation technology and management of cabbage? Cabbage cultivation technology and man

Cabbage cultivation is first to raise seedlings, cultivate seedlings and seedlings strong good seedlings, and then apply compound fertilizer to turn over the soil, spacing 40 to 50 cm seedlings watering, do not water the first ten days after planting, control the seedlings to pull high and long, this is called blunt seedlings, blunt seedlings after feeding nitrogen fertilizer to urea-based, watering every six to seven days, to promote urea full ** cabbage growth, when cabbage core is large and hard four or five days before picking, do not water again, to prevent cabbage cracking, affect the appearance.

Tips on cabbage cultivation techniques.

1. Select the variety.

Choose early-maturing varieties with a relatively short growth period, a single weight of about one kilogram, and about 45 days after planting until the harvest period, which is the most suitable for consumers, so that it will not affect the planting period of overwintering vegetables.

2. Sow seeds at the right time.

The seedlings of cabbage are not very strict in terms of temperature, only when they set balls, the temperature requirements are very strict, about 17 degrees Celsius, which is the most conducive to the growth of leaf balls. Planting in the summer usually begins around late July.

3. Cultivate strong seedlings.

1) Make a seedbed: the seedbed should be well ventilated, the terrain is relatively high, there is a convenient drainage and irrigation system, the same family of vegetables has not been planted, it should be relatively close to the planting field, and there is no polluted field. The formula of the seedbed soil is made of filled soil and decayed organic fertilizer, in accordance with 6:

The ratio of 4 was proportioned, and the ternary compound fertilizer, carbendazim and phosphine granules were fully stirred in the nutrient soil and began to make furrows.

2) Sowing and seedling: In the second half of July, the seedbed is fully irrigated, and after it is completely wet, the seeds are evenly sprinkled on it, and then covered with a layer of fine soil, covered with mulch, more than 70% of the seedlings emerge, and the mulch film is immediately uncovered to prevent roasting and damaging the seedlings. When the seedlings grow to two leaves and one heart, the first seedling division, it is best to choose the evening or cloudy day for the seedlings, so as to ensure the survival rate of the seedlings.

Watering after seedlings should be carried out in the dark ditch, and it must be watered thoroughly.

3) Seedbed management: the seedlings are very resistant to stress, we must do a good job of insect control, pay attention to weeding, and be sure to avoid being eaten by insects and grasses. The main pests of cabbage are aphids, cabbage insects, and diamondback moths, which can be used alternately with Wanling and avermectin, which can effectively control pests.

Due to the very short duration of the seedling period, drug control can be used about twice depending on the actual situation of the pest.

Brussels sprouts are planted with seedlings and colonization; Management skills are mainly field management.

1. Seedling

Brussels sprouts are generally sown and raised. Cultivating strong seedlings is the key to the cultivation of Brussels sprouts, because the seeds are mostly hybrid generation, the most expensive, so it is best to use a nutrient bowl or a hole tray to raise seedlings, summer and autumn sowing seedlings must also be shaded, rainstormproof, in order to improve the emergence rate, is conducive to cultivating strong seedlings and reducing seed costs. If sowing in the seedbed, it is necessary to choose a plot with good ventilation and convenient drainage and irrigation, and cultivate an area of 667 square meters, with a seed amount of 25 30 grams and a seeding bed area of 4 square meters.

After sowing, cover the shallow soil, directly cover the shade net on the bed surface, and then water thoroughly to keep it moist, and remove the shade net in time when the seeds begin to emerge. In order to cool down and prevent heavy rain, it is advisable to build a shed on the furrow to continue to cover the shade net. During the period from emergence to planting, seedlings can be divided once.

Strengthen management during the seedling period, top dressing and watering according to the seedling situation, and prevent and control the harm of diseases and insects at the seedling stage. When the seedlings grow to 5 or 6 true leaves, they can be planted when the seedlings are generally 35 to 45 days old.

2. Colonization

The cultivated field should be deeply cultivated and sunned, and sufficient base fertilizer should be applied. Apply 3,000 kg of decomposed compost and manure per 667 square meters, 15 kg of urea, 25 kg of superphosphate, plough the soil, rake flat furrows, furrow width meters, dwarf species each furrow two rows, plant spacing 40 cm, 2000 plants per 667 square meters. Tall species, each row of seeds, about 1,200 plants per 667 square meters.

Field management

Due to the long growth period of Brussels sprouts, in addition to the application of sufficient basal fertilizer, it is also necessary to top dressing according to the growth period. 4 5 days after planting, apply live fertilizer, one month after planting to apply seedling fertilizer, promote plant vegetative growth, before the balling stage of the plant outer leaves are best up to about 40, the third top dressing is carried out in the bud bulb expansion period, the fourth top dressing is carried out in the bud ball harvest period. The types of fertilization can be human and animal manure water and urea solution, generally 10 15 kg of urea per 667 square meters each time.

Attention should be paid to cultivating weeding and rhizosphere soil cultivation to avoid the plant swinging when it is windy and rainy, which will affect the formation and expansion of bud balls. In windy areas, bamboo poles or tree branches should be used to cut them. Once the middle part of the stem produces a small bud ball, the lower leaf is removed, which is conducive to ventilation and light transmission, promotes the development of the bud ball, and is convenient for harvesting the bud ball.

First of all, we should choose the right soil, but also should improve the fertility of the soil, timely watering and fertilization, strengthen water and fertilizer management, ensure the permeability of the soil, do a good job of drainage and ventilation, timely spraying of pesticides, to ensure sufficient light and suitable temperature.

First of all, it is necessary to choose high-quality soil, and at the same time, when cultivating, we must choose fertile and well-drained soil, and then we must pay attention to the appropriate depth, we must choose high-quality seeds, and we must water and fertilize in time.

To understand the habits of cabbage, we should also pay attention to management techniques, do a good job in prevention and control, and pay attention to the cultivation of cabbage seedlings.

To disinfect the soil, first of all, the soil is fully disinfected, and after applying a well-rotted organic fertilizer, watering is kept moist; Seed treatment, the seeds are treated with disinfectant and then dried, and then soaked in warm water for 24 hours; Start sowing, plant the seeds into the soil separately, and control the temperature at about 20; Post-sowing management, the seedling stage should be given sufficient sunlight every day, and the rotted organic fertilizer should be applied every half month.

Cabbage likes to grow and develop in soft soil full of organic matter, before planting, the soil is deeply cultivated and carefully treated, and a thin decomposed organic fertilizer is added, and the moist condition is maintained after pouring water, and the soil needs to be disinfected and sterilized once.

Because the seed coat of cabbage is a bit hard, before planting, first select the full seeds that are easy to survive and grow and develop strongly, peel off the epidermis of the seeds, soak them in warm and hot water for 24 hours, so that they slowly absorb water and rise, and then put them in a ventilated place in the back to dry, and they also need to be disinfected and sterilized once.

The treated cabbage seeds are planted separately in the soil, maintaining the interval between each plant at about 25 cm, pouring water immediately, often keeping it moist, controlling the ambient temperature at about 20, and so on After the leaves emerge, it can be transplanted to promote the growth and development of rhizomes.

At the seedling stage, give sufficient light treatment every day, try not to shade, and when the plant height can reach 10 cm, apply a well-rotted organic fertilizer every half month, each fertilization should be combined with watering, and then watering should be maintained on the principle of seeing dry and wet.

Cabbage is a vegetable that we eat regularly every day. Cabbage seedlings do not have strict temperature requirements, but the temperature requirements at the heading stage are very strict, which should be around 17, which is conducive to the formation and growth of leaf bulbs. So the summer sowing time is around late July.

The seedbed should be a pollution-free plot, with good ventilation, high terrain, convenient drainage and irrigation, no vegetables in the same family, and close to the planting farm. <>

The seedbed soil formula is 6 parts of field soil and 4 parts of decomposed organic fertilizer. Add 1 kg of ternary compound fertilizer, 80 grams of carbendazim and 100 grams of phoxanthion to each cubic meter of nutrient soil, mix evenly, and make a bed. The width of the bed is metre, and the length is not limited.

In late July, the prepared seedbed is watered with foot water, the seeds are evenly sown, covered with fine soil about 1 cm, covered with film to moisturize, arches are inserted, and covered with shade nets. When more than 70% of the seedlings are unearthed, remove the plastic film in time to prevent the seedlings from being scorched. When the seedlings grow to 2 leaves and 1 heart (about 10 days after sowing), they can be divided into seedlings once, which is conducive to survival in the evening or cloudy days.

Seedling water should be poured into a ditch and washed thoroughly. Cabbage seedlings are resistant to stress, but they must be insect and weed-proof so as not to be eaten by Cordyceps. The main pests are aphids, diamondback moths, and cabbage worms, which can be used alternately with Wanling and avermectin.

Due to the short nursery period, it can be used in two times depending on the insect condition. <>

It is advisable to choose non-cruciferous beans or melons as the plot of the previous stubble, apply 3000 kg of decomposed organic fertilizer per mu, 30 kg of nitrogen, phosphorus and potassium ternary compound fertilizer, turn the ground to make a meter-wide ditch, plant 2 rows, plant spacing 40 cm, and protect 2500 3000 seedlings per mu. When the seedlings grow to 5 or 6 leaves, they should be sprayed once before planting, that is, when the seedlings are clustered in the seedbed, spray chlorothalonil 600 times and Valium 3000 times. After planting, it should be properly managed, generally without medication, and there is basically no disease during the whole growth period.

When planting, it should be watered in time to slow down the growth of seedlings, but do not dry the seedlings. Cabbage has a long growth period, so it is necessary to apply dilute application frequently in the early growth stage, and more application in the rosette stage, mainly nitrogen fertilizer. 1% compound fertilizer or urea water can be topdressed 7 days after field planting, and then every 7-10 days.

The amount of fertilizer at the rosette stage should account for 50% of the total amount of fertilizer, and the amount of phosphorus and potassium fertilizer should be increased appropriately. <>

1. Spring planting cabbage is most prone to the phenomenon of "unripe sprouting", so it is advisable to choose excellent varieties with early maturity, not easy to sprout, and strong disease resistance in spring cultivation of cabbage, and sow seeds at the appropriate time to avoid sowing too late or too early to cause the phenomenon of sprouting or delaying the maturity period.

2. Before planting, the plant needs to be deeply turned over to make furrows, apply sufficient base fertilizer, and after planting, water in a timely manner, spray 600 times of new high-fat film to retain moisture and moisturize, isolate bacterial infection, and protect seedlings to thrive.

3. After about 15 days of planting, the first top dressing should be carried out, and the foliar spraying of vegetable stems can improve the ability of cabbage to absorb water and fertilizer, and the plant will grow lush and the leaves will be thick. Then properly control the water and squat the seedlings, end the squatting seedlings when the bulbs begin to hug and carry out the second top dressing, and apply the manure and urine of the rotting mature people with water. After that, watering should be done every 7 days, but should be stopped a few days before harvest to facilitate transportation.

First of all, when planting, we must choose the soil is more fertile and broad land, in the process of fertilization, we must choose farmhouse fertilizer, do not use the fertilizer bought outside, but also pay attention to watering, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides.
