What are the key points of planting techniques for autumn and winter cabbage? What do you need to pa

The key point of planting Chinese cabbage in autumn and winter is to make the soil more fertile, so that the cabbage can grow better. The soil should be fertilized before planting bok choy, and the structure of the soil can be adjusted to allow the fertilizer to mix evenly. When the seeds are sown in, the seeds grow quickly and take root.

Fertilizer is very important for seeds, so when doing these things well, it is important to organize them in time. Whether the cabbage is rooted deep depends on how close it is to the ground, and the soil should be loosened from time to time. <>

When planting bok choy, don't go directly to the seed store to buy seeds, you can choose to buy some seeds at the market. When you get home, you can soak the seeds in warm water before sowing them. There are two ways to sow cabbage, the first is to scatter, and the second is to sow strips.

Sowing means sowing seeds directly, as long as they are not too dense, and strip sowing is to hollow out in advance according to the density of planting. If you plant it, you can make the cabbage better managed in the later stage, and you can also make the cabbage grow better and better. <>

Cabbage can be grown all year round, but the temperature requirements are not as obvious as the increase. If you need to water the bok choy from time to time, it will sprout in a few days. When the cabbage is ripe, you can let the soil moisten a little.

Not only should the bok choy be watered, but also sprinkled with some plant ash on the bok choy. Grass ash can prevent a variety of diseases, so that there are no insects on the cabbage. <>

In general, cabbage grows relatively quickly, so you must pay attention to some details in the process of planting. If you are growing in your own vegetable patch, water it in the morning or evening. When the weather is hot, you can make an awning on it so that it is not directly exposed to the sun.

1. Sowing time autumn and winter cabbage is generally sown in batches from September to early October, 20-30 days after sowing, some seedlings can be marketed, and most of them are planted after planting. It is recommended to choose medium-ripe cabbage varieties with strong cold tolerance and good quality. The sowing rate per mu is kilograms.

2. Seedling management For transplanting seedbeds, seedlings should be seedlings 2 times during the seedling period. 6 10 days after emergence, when the seedlings grow 1 2 true leaves, the first seedling is carried out, and the seedling spacing is about 3 cm. After an interval of 5 to 7 days, the second seedling is asked, leaving the strong and weak, and the seedling distance is about 6 cm.

After each seedling, dilute manure water can be applied once to promote the purpose of seedlings and seedlings. Autumn and winter cabbage planting technology points 3, timely planting of cabbage generally plant spacing in 15 25 cm, row spacing in 20 35 cm, planting after October can be planted deeper, which is conducive to cold protection, sandy loam soil can also be appropriately deep planting, clay soil can be appropriately shallow planting.

The cost of planting, the planting process, the frequency of watering, the process of cultivation, the problems of diseases that arise. It is necessary to pay attention to the way of sowing, the skills of planting, the way of water and fertilizer management, and the mode of fertilization and watering of planting characteristics.

It is necessary to pay attention to the condition of the land, pay attention to sowing, pay attention to daily management, pay attention to water and fertilizer management, and must be picked when it grows to a certain extent.

1. Sowing time.

Generally, it is advisable to plant Chinese cabbage within three to five days before and after the beginning of autumn as a node. If the temperature is on the high side, you can postpone it for a few days.

1. Soil preparation and fertilization.

It is best to choose a plot that has not been planted with cabbage before, and before sowing, apply well-rotted farmhouse fertilizer and Bika microbial agent as the base fertilizer in the vegetable field, and then deep plough and rake flat.

2. Planting density.

Generally, it is planted on flat ground. Two rows of Chinese cabbage are planted in a bunch, and the row spacing is kept at a distance of about 70 cm, and the plant spacing is kept at about 60 cm.

3. Field management.

After the Chinese cabbage seedlings are unearthed, they should be watered frequently to maintain temperature and humidity. When the Chinese cabbage seedlings grow to a leaf, the seedlings should be planted, the strongest Chinese cabbage seedlings are selected, and the rest of the Chinese cabbage seedlings are dropped, in order to prevent the seedlings from being staggered, the root system of the cabbage seedlings is shaken by external forces and wilts, it should be watered in time after the seedlings, and at the same time of watering, with top dressing, in order to supplement the nutrients required for the growth of the cabbage seedlings, in the later stage of the growth of the Chinese cabbage, the Chinese cabbage should be bundled.

4. Harvesting. After the Chinese cabbage is harvested, it can be stored after drying in the sun, and when the outermost cabbage leaves are a little dry, they can be cellared, which is easier to preserve.

The key points of autumn Chinese cabbage cultivation technology are introduced as follows:

1. Select the variety. Generally, the plots with good fertilizer and water conditions are selected as tall, late and medium-ripening varieties; Dwarf and early-maturing varieties are selected for plots with poor fertilizer and water conditions.

2. Fertilization and land preparation. Land preparation should be fine, combined with land preparation, apply 5000 kg of high-quality farm fertilizer, 20 kg of diammonium or 50 kg of superphosphate, 25 kg of potassium sulfate or 30 kg of ternary compound fertilizer per mu. After the land preparation is completed, the width of the ridge is 30 cm, the width of the ditch is 30 cm, and the height is 15 cm.

3. Sow seeds at the right time. The sowing date of autumn Chinese cabbage is generally 1-2 days before and after the "beginning of autumn", that is, around August 8, the disease is heavier too early, and the yield is reduced too late. Live broadcast on the ridge according to the plant spacing of 35 cm (no slow seedlings are required for live broadcasting).

4. Field management. 1. Seedling management: water after sowing, and then water in time according to the weather conditions after the seedlings are set to prevent high temperature and drought from affecting the growth of seedlings.

Timely tillage after watering or after rain;2. Rosette period management. Apply 10 kg of urea per mu, water or flush fertilizer with water in time after fertilization, and master the principle of seeing dry and wet in the future3. Management of the clutching period. Apply 15 kg of urea per mu, water every 5-6 days or flush fertilizer with water, and always keep the soil moist and the water is uniform.

Stop watering 8 days before harvest to avoid excessive moisture in the spheres and cause rot.

5. Prevention and control of pests and diseases. 1. Prevention and control of Chinese cabbage disease: use 80% enoylmorpholine 800 times solution to prevent and control downy mildew;Use 20% thioxine copper 600 times solution to prevent and control soft rot;Use 10% ningnanmycin 500 times solution to prevent and control viral diseases;Spray manganese sulfate 500 times solution to prevent and control dried Chinese cabbage heartburn (it is now reported that dried Chinese cabbage heartburn is caused by a lack of effective manganese);2. Prevention and control of Chinese cabbage insect pests

Use 10% cypermethrin 1000 times solution to control cabbage worms;Use 10% bromocyanide fenciliprole 600 times solution to prevent and control jumping nails;Use 10% imidacloprid 1500 times solution to control aphids.

When the temperature is about 0 degrees, whether to laminate the film to keep warm.

To use base fertilizer in a timely manner, and the long cycle of cabbage is relatively short, it is necessary to increase the fertilizer reed material in time, pay attention to the selection of seeds or friends, and cultivate in advance.

In the process of planting cabbage, we should cultivate excellent varieties of Tonghongyan, and in addition, before planting silver, we should choose loose and fertile soil, and pay attention to reasonable field management.

1.Soil-based fertilizer. Before planting bok choy, the soil should be fertilized.

This is because the growth cycle of clay fertilization is very important. It is recommended that you use the agricultural bureau and home manure as base fertilizer, sprinkle it on the soil surface, and then turn the soil shallowly to ensure that the soil and fertilizer are mixed evenly. 2.

Land consolidation. After fertilizing the cabbage planted in the hall, land consolidation is required. The root system of Chinese cabbage is shallow, the leaf surface is close to the soil layer, and the soil moisture is more likely to affect the Chinese cabbage.

In order to facilitate the water control treatment of cabbage in the later stage, it is necessary to ditch the soil before planting to ensure that the soil layer does not accumulate water for a long time. 3. Seed selection and sowing. Nowadays, most bok choy is purchased directly at seed stores.

This seed does not need to be treated, because it has been treated in advance, and the cabbage raised by yourself needs to be woken up with warm water, soaked in potion, etc., before planting.

Sowing time, cabbage growth cycle is short, generally planted for about 20 30 days, can be picked by the tree. Autumn and winter cabbage is planted in September and October, and in the south it can be planted in December. Spring cabbage is planted in February-mid-April, and summer cabbage is planted in May and August.

Ploughing and fertilizing, cabbage has strong adaptability to the soil layer, and grows and develops stronger in the soil with rich soil and good water retention and soil fixation. When ploughing, it can be made into a flat furrow with a width of 1 meter. There is a lot of rain in summer and autumn, so it should be planted with high furrows and leveled on the furrow surface.

The base fertilizer is used with base fertilizer, which is mixed with the soil layer evenly, and when the soil layer is acidic, lime powder should be added when ploughing.

Planting, cabbage planting has sowing, hole sowing and seedling transplanting, sowing with seed volume amplification hole sowing more, generally in spring and summer planting, the choice of sowing method. When planting in spring and winter and in greenhouses, it is necessary to pre-plant seedlings before planting. Before planting, it should be soaked in warm boiled water for 12 hours, and then carried out tooth promotion at 15 20 times, and the planting was completed after the germination of more than half of the seeds.

Before planting, it should be watered, sown after the furrow surface is wet, and fill with 1 cm of soil.

Seedling management method, cabbage in the germination to maintain the soil layer moist, budding dense areas to complete 2 times of replenishment of seedlings, the emergence of 2 leaves when the first replenishment of seedlings, seedling spacing in two centimeters, the weak seedlings and diseased seedlings are picked. The second seedling replenishment is completed when 3 or 4 leaves are grown, and the seedling spacing is five or six centimeters. After each replenishment of seedlings, it is necessary to do a good job of watering.

Cabbage should be planted when five or six leaves emerge, with a spacing of 10 to 15 cm. After the cabbage is transplanted, it is necessary to water the transplanting water to promote the slow rooting.

Fertilizer and water management methods, cabbage can be picked during the vegetative growth period, and there are more nitrogen elements necessary, and less phosphorus and potassium fertilizers. After the cabbage enters the growth and development growth period, it is necessary to top dressing a little base fertilizer, and 1 mu can use 10 15 kg of urea solution. Phosphorus and potassium fertilizers are applied in basal fertilizers, and leaves can be sprayed with potassium dihydrogen phosphate and amino acid foliar fertilizers in the middle and late stages.

The water consumption of cabbage seedling stage is small, and the soil layer is maintained dry and wet. To the growth and development of the growth period, every 3 4 days of water injection, winter planting, the frequency of sprinkling is reduced, to avoid the reduction of ground temperature after watering, harm the growth and development of rhizomes.

Cabbage pest management: although cabbage is easy to plant and grow, but during the growth period if you encounter insect pests also need to be prevented and controlled in time, which small insects like to invade cabbage, especially in summer and autumn, if you observe carefully, you will find a lot of small wormholes from the leaves, this time it is necessary to prevent and control as soon as possible, if there are cabbage planted at home, you should pay attention to it, early prevention and control.

Cabbage for the soil requirements are not very strict, as long as it is not particularly sticky and barren soil, can be sown, before planting to deep level the land, and apply enough base fertilizer, vegetable garden planting cabbage, most of them love to use their own soil fertilizer mixed with some plant ash as a base fertilizer, the effect is also good, without these fertilizers, you can use compound fertilizer instead. Cabbage planting is small, sowing in summer and autumn, due to the high temperature, planting cabbage, it is not necessary to soak and germinate, but to ensure that the soil is moist, only good moisture, in order to make the cabbage germinate in a very short time, sowing cabbage to take the way of sowing, we love to mix the cabbage seeds with some cinders, stir evenly and then carry out the sowing, which is conducive to the emergence of seedlings evenly, after sowing, use a rake to cover up. After the seedlings emerge, when the cabbage grows with four or five true leaves, it can be thinned and planted.

To cultivate cabbage in summer, we should choose excellent varieties, and then control the temperature, humidity, and be sure to prevent insect pests. In summer, the temperature is high, so sowing can be carried out by direct broadcasting.

Selection of varieties: For plots with good fertilizer and water conditions, choose tall and late mid-maturing varieties, and choose dwarf and early-maturing varieties for slightly barren fields. Fertilization and land preparation:

Combined with land preparation, apply high-quality farm fertilizer, superphosphate, etc. per mu, and make furrows after land preparation. Sowing at the right time: Sow within 1-2 days after the beginning of autumn, and sprinkle Chinese cabbage seeds directly into the plot.

1. Select the variety

When planting Chinese cabbage in autumn, the corresponding varieties should be selected according to the plot conditions, generally the plots with good fertilizer and water conditions should be selected with tall trees and late and medium-ripening varieties, and the plots with poor fertilizer and water conditions should be selected with dwarf trees and early-maturing varieties.

2. Fertilize and prepare the land

After the Chinese cabbage seeds are selected, they should be combined with land preparation, apply 5000 kg of high-quality farm fertilizer, 20 kg of diammonium or 50 kg of superphosphate per mu, and make furrows after land preparation, with a ridge width of 30 cm, a ditch width of 30 cm, and a height of 15 cm.

3. Sowing of stuffy rock limbs at the right time

Autumn planting Chinese cabbage, the sowing period is generally 1-2 days before and after the beginning of autumn, that is, around August 8, planting too early, the plant disease is heavier, sowing too late, its yield is reduced, live broadcast on the ridge according to the plant spacing of 35 cm, the seeds are evenly sprinkled on the surface, covered with fine soil.

4. Field management

Chinese cabbage is watered once after sowing, and the seedlings are watered according to the weather conditions after the seedlings are set to prevent high temperature and drought from affecting the growth of young jujube seedlings, and cultivated in time after watering or rain to ensure that the soil is loose, and 10% cypermethrin 1000 times liquid should be used to control cabbage insects to reduce pests and diseases.
