Autumn and winter cabbage cultivation techniques, open field wintering cabbage cultivation technique

1. Planting: select seedlings with an age of about 40 days, 6-8 true leaf strong seedlings, and plant them in the evening on cloudy or sunny days, with a row spacing of 55 cm and a plant spacing of 35-40 cm, and 3000-3500 plants per mu.

2. Water and fertilizer: after the planting of seedlings in early spring film cultivation, due to the low temperature in spring, generally small water, watering should be properly controlled to increase the ground temperature, not flood irrigation, urea with water, if there is cold weather, irrigation can enhance the cold resistance of plants.

3. Harvesting: When the leaf balls are harvested in a timely manner, keep 2 outer leaves (rosette leaves) to protect the leaf balls during harvesting, so that the surface is clean, no insect pests, and no cracked balls. At the same time, according to the standard requirements of fresh-keeping processing exports, the size of the leaf balls is graded.

** market, depending on the demand, timely harvest and listing.

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.

1, timely sowing timely sowing is one of the important technical measures for spring cabbage cultivation, if sowing too early, seedlings grow larger, continuous low temperature in early spring, so that seedlings prematurely through the vernalization stage, easy to occur early moss, on the contrary, sowing too late, the maturity period is delayed and affect the economic benefits, before sowing the seedbed will be watered, with a new high-fat film dressing (can be mixed with seed coating agent), to repel underground pests and diseases, isolate virus infection, strengthen respiration intensity, improve seed germination rate.

2. Seedling management In order to cultivate strong seedlings, seedling temperature management is very important, after sowing, the grass curtain needs to be covered at night, and the temperature can be appropriately reduced after the seedlings emerge, and the temperature should be ventilated in time regardless of sunny or rainy days. And spray on the surface of plants with a new high-lipid film, which can prevent bacterial infection, improve the ability to resist natural disasters, improve the intensity of photosynthesis, and protect the growth of seedlings.

3. Field management Watering in time after planting to improve the survival rate of seedlings, and ditch drainage should be cleared during the growth period to maintain good root development. In time, the plant stem is thick and the plant is lush. At the same time, it can improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual toxicity.

At the same time, it is necessary to strengthen the comprehensive control of pests and diseases, and spray new high-lipid film to enhance the control effect.

If you really want to plant, you can buy one or two professional books and learn experience from the relevant planting base, so as not to cause losses due to planting technology.

The time of cabbage planting is actually not fixed, because the different climates in different regions have a great impact on the growth of cabbage, so spring cabbage, summer cabbage, autumn cabbage and winter cabbage will appear in the market. Under normal circumstances, the best planting time for cabbage is in April in spring and September in autumn, and the temperature suitable for cabbage growth is 20 to 28 degrees, so the yield of cabbage planted in these time periods is high.

How to grow overwintering cabbage:

1. Sowing seeds and raising seedlings.

Overwintering cabbage has to be sown in the greenhouse from early October to mid to late November, the seedling age is short, can be sparsely sown without seedling, the seedling age is generally 30 40 days, the seedling age can reach 60 70 days, the middle seedling is divided once, the purpose is to cultivate large seedlings and strong seedlings.

Second, the land is prepared to make furrows.

The furrow for cultivating cabbage should be fertilized, the ground should be turned over, and the furrow surface should be leveled. It can be made into a flat furrow, and can be made into a high furrow.

The flat furrow can be made into a wide meter, and the seedlings are planted according to the row spacing of the plants. The high furrow can be made into a height of 10 15 cm, a width of about 30 cm, a furrow width of about 30 cm, and 2 rows of cabbage are planted on both sides of the high furrow, and the plant spacing is about 30 cm.

3. Colonization. After planting seedlings according to the hole, water once, only wet the soil, in case the ground temperature is lowered after the water, and then water again after 7 10 days, and then cultivate and loosen the soil, promote root growth, accelerate the growth of leaves and differentiate new leaves, form fat rosette leaves, and lay the foundation for early balling and good balls.

In mid-December, the seedling tray was raised in a small arch shed.

It is necessary to prevent seedlings from being raised too early, because the seedlings are long and easy to moss.

In order to prevent the seeds from carrying pathogens, soak the seeds with carbendazim for 24 hours before sowing.

Hello, it generally takes about 90 days, and it generally takes about 1 month for cabbage seedlings to grow in winter. According to the maturity of the variety and the listing requirements, the following two time periods can be selected for winter harvest: autumn sowing is sown from July 20 to August 10, the seedling period is generally 30-35 days, and after planting, it can be harvested and marketed from November to March of the following year; Winter sowing can be sown from September 1 to 20, and after planting at the end of October, it can be harvested and marketed in February and March of the following year.

: In late September, it is recommended to plant winter and spring No. 1 cabbage.
