How to grow cabbage

1. Soil selection.

Cabbage does not have strict requirements for planting soil, and can be cultivated on sandy loam, loam, and clay soils, and has strong environmental adaptability. If you want to maintain high yield and high quality, it is best to choose loam soil with high organic matter content, deep soil layer, strong water and fertilizer retention ability, and it is important to note that the previous crop cannot be cruciferous vegetables.

2. Sow seeds at the right time.

Cabbage sowing is generally carried out at noon on a sunny day, after leveling the seedbed, slightly suppressed, watered through the bottom water, sprinkled with a layer of fine nutrient soil, covered with soil after seed sowing, the thickness is 1 cm is appropriate, and do a good job of heat preservation and moisturizing. In order to facilitate the emergence of seeds, we can cover the furrow surface with a double-layer shade net or straw after covering the soil, so as to better moisturize and heat preservation, and promote the emergence of seedlings.

3. Seedling management.

When the cabbage seedlings have grown to 2-3 true leaves, they need to be separated. When the seedlings have 4-5 leaves, we start to ventilate the seedlings and reduce the temperature in the shed appropriately. In the seedling refining period of cabbage, we generally do not water, and the seedling refining time is generally one week.

4. Water and fertilizer management.

Under normal circumstances, about 15 days after planting, the first top dressing irrigation is carried out, and the seedlings are properly controlled and squatted later. When the bulbs begin to hold, the squatting should be ended, and the second top dressing irrigation should be carried out. After that, water every other week, and during the coating period of the cabbage, you can do the third top dressing.

Watering should be stopped about 10 days before the final harvest to prevent the balls from splitting and causing unnecessary losses.

5. Weeding and loosening the soil.

From 15 days after planting to 10 days before harvesting, we need to cultivate and loosen the soil and weed 2-3 times, which is conducive to raising the ground temperature and strengthening the soil.

Breathable, able to promote rapid root development. Generally, after watering twice, the soil skin turns white, at this time, it should be combined with loose soil for weeding, with a depth of more than 5 cm. After heavy rain, it is also necessary to loosen the soil in time to prevent the soil from being hypoxic.

Cabbage can be grown in spring and autumn every year. At this time, the temperature is more suitable for the growth of the plant, the seeds can germinate as soon as possible after planting, when planting cabbage, the seeds can be sown directly in the fertile and loose soil, and covered with fine soil, after planting, you can water the soil without polluting water to keep the soil moist.

When planting cabbage, you can select healthy seeds with full grains and have not suffered from pests and diseases, then soak the seeds in warm water at 50 degrees for 10 minutes, take them out, drain the water, spread them evenly in the prepared soil, and cover the seeds with 3 cm of fine soil.

In the later stage of the maintenance of cabbage, it can provide it with all-day sunshine, so that the plant can carry out photosynthesis normally, can also provide mineral-rich water for the cabbage, keep the soil in a moist state, and can also put some insect attractant pills into the area where the cabbage is planted to eliminate pests near the plant.

In general, the best time to grow cabbage is in April in spring and September in autumn, and the most suitable temperature for cabbage growth is 20 to 28 degrees, so the yield of cabbage planted in these time periods is high.

The temperature requirements for sowing cabbage seedlings in time are not strict, but the temperature requirements for the balling stage are very strict, which should be about 17, which is conducive to the formation and growth of leaf bulbs. Therefore, the summer sowing time is around late July; To cultivate strong seedlings, the seedbed should choose a pollution-free plot with good ventilation, high terrain, convenient drainage and irrigation, no vegetables of the same family, and close to the planting field.

Precautions for cabbage planting

Kale is a light-loving plant that is not shade-tolerant, so when it is farmed, it should be placed in a place with plenty of light, preferably in a place with scattered light and good ventilation. However, it should be noted that in the summer when the sun is strong it is necessary to take a shaded place, otherwise its leaves will be sunburned, and in severe cases, it will die of dehydration.

Kale is a plant that prefers cold climates and can be cold and heat-tolerant, so kale cultivation is relatively easy. The suitable temperature for kale growth is 15-20, if the temperature is too high, its growth rate will be slowed down, and its growth will also be affected in severe cases.

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 Brassica plant in the cruciferous family, also known as wild cabbage, native to Western Europe and the Mediterranean coastal region. Cabbage has strong survivability and has been widely cultivated after being introduced into China. The edible part of cabbage includes young leaves and bulbs, which can be used as pickles or salads, as well as as livestock feed.

The seeds are soaked in warm water at about 30-40 degrees indoors, which not only awakens the dormancy period of the seeds, but also removes some pathogenic bacteria on the epidermis. Sow about 6 mm deep, lightly cover and compact with sieved shallow fine soil, 0-10 vernalization (seedlings can grow faster after vernalization), grow for 4-6 weeks and then transplant outdoors. Cabbage is suitable for growing in well-drained, loaf soils, such as humus-rich clay and sandy soils.

Cabbage seedlings are planted in clay, sandy soil, or well-drained substrates such as ceramsite, vermiculite, permeable perlite, etc. Planting in a place with high sunshine intensity and long sunshine time can maximize the photosynthesis of cabbage leaves and store carbohydrates.

Cabbage is suitable for planting in a breathable soil environment, and frequent, heavy watering should be avoided in favor of small amounts of sprinkler and drip irrigation. The roots must be watered thoroughly and not stored too much between the leaves and the bulbs. Fertilization should be varied and moderate.

In addition to meeting the basic inorganic fertilizer requirements such as nitrogen, phosphorus, potassium, calcium, magnesium (re-applying nitrogen fertilizer, appropriately increasing phosphorus and potassium fertilizer), fully decomposed farmhouse fertilizer and appropriate organic fertilizer should also be applied. Organic fertilizer can not only provide comprehensive nutrients such as organic acids and peptides, but also improve the soil microenvironment, enhance the stress resistance of cabbage, improve disease resistance, and reuse organic fertilizer and phosphate fertilizer. And after the cabbage enters the heading stage, it is topdressed in time to ensure that the bulb has enough nutrients and can expand rapidly in a short time.

Each type of cabbage has its own sowing time. Taking autumn cabbage as an example, the growth period of autumn cabbage will be restricted by frost. Therefore, the suitable sowing date of autumn cabbage should be determined according to the growth period of the selected variety.

Depending on the time of the start of the annual frost, the sowing time of the cabbage can be calculated to prevent frost before ripening. The seedling stage meets the requirements of fertile soil and easy drainage. Light and thin fertilizer was applied at the seedling stage to promote the growth of cabbage plants after the seedling stage, and it was combined with water at the seedling stage.

During the growth period, water and fertilizer should be satisfied, especially during the formation of leaf bulbs or flower bulbs, and the demand for fertilizer and water for the growth and development of cabbage plants should be met in a timely manner. The key fertilization period for cabbage is the rosette leaf growth period. Brussels sprouts can be fertilized in the early and middle stages according to soil fertility.

Meta-rosette, early nodulation and meta-nodulation.

When planting, the first point should be to pay attention to the whole planting time to be mastered, the second point the entire space must be mastered, and the third point should be the most basic cultivation time and solar terms.

Choose the best varieties, early maturing varieties with short growth period, timely sowing, the temperature is about 17 degrees Celsius, and the seedbed is well ventilated, the terrain is higher, and the location is convenient for drainage and irrigation.

It should be planted in fertile soil, so that the cabbage can get high nutrients and can grow better.

In fact, the best way to plant is to pay attention to the fact that the soil should be more moist and fertile, and this relatively large site should be selected, so that it is more spacious and bright, and the process is very good.

1. Land selection and land preparation.

Plots with high terrain, cool ventilation and convenient drainage and irrigation should be selected. After the harvest of the previous crops, 5,000 kg of well-rotted high-quality circle fertilizer was applied every 667 square meters (1 mu) to prepare the land.

2. Sow seeds and raise seedlings.

Before sowing, water 1 time, after the water seeps down, sprinkle 1 layer of fine soil, and then spread the seeds evenly. The sowing amount is about 4 grams per square meter. Immediately after sowing, cover 1 cm of soil to prevent the harm of mole crickets, and spray 1200 times phosphine on the furrow surface.

Cover with 1 layer of plastic film or black film to maintain the humidity of the furrow surface.

3. Colonization. Select seedlings about 40 days old, 6-8 true leaves and strong seedlings, planting in the evening on cloudy or sunny days, row spacing of 55 cm, plant spacing of 35-40 cm, and planting 3000-3500 plants per mu.

4. Field management.

After planting and planting seedlings, it is generally flooded with small water, and about 15 kg of urea is applied with water. As the temperature rises, enter the early stage of the late rosette, increase fertilizer and water, properly control the watering at the end of the rosette, and timely cultivate and weed. Pay attention to drainage after rain.

5. Pest and disease control.

Cabbage has few diseases, mainly aphids and cabbage worms. Aphids: 50% aphid-killing emulsifiable concentrate 1000 times liquid spray control, cabbage insects: 20% pyrethrin emulsifiable concentrate 2000-3000 times liquid spray control.
