Chinese cabbage planting methods and steps, Chinese cabbage planting methods

<>1. Select the plot: select the plot where the previous crops are early cucumbers, early peppers and other crops as the planting land, then plough the soil, level the ground, and apply farmhouse fertilizer. 2. Select the variety:

Varieties with strong disease and insect resistance were selected as planting objects. 3. Sowing method: Dig the sowing hole, and sow 3-4 seeds in each hole.

4. Field management: After the seeds emerge, check the seedlings in time to replenish the seedlings, and transplant them in time when the seedlings grow 5-6 true leaves.

1. Select a plot

1. Continuous cropping of Chinese cabbage is prone to disease, so it is necessary to carry out crop rotation, which is usually suitable for water and drought rotation and grain and vegetable rotation.

2. The pre-crop crops of the planting site should be early beans, early cucumbers, early tomatoes, and early peppers, and the soil should be ploughed before sowing, the soil should be broken and leveled, and sufficient rotten farm fertilizer should be applied.

Second, choose the variety

Choose early-maturing varieties or varieties with strong disease resistance, insect resistance and storage resistance as planting objects, and you can also choose suitable varieties according to the local market environment.

3. Sowing method

Chinese cabbage is suitable for direct seeding, after the soil is ready, the ridge should be made, and then the sowing hole can be excavated, 3-4 seeds can be sown in each sowing hole, and after sowing, it should be watered once permeable and covered with plastic film.

4. Field management

1) After the seeds emerge, the seedlings should be checked and replenished in time, and the soil should be loosened and weeded at the same time.

2) The seedlings can be divided into several times, when pulling the cross, you can choose to leave 2 cabbages with good growth, and after a period of time, you can leave 1 seedling with the best growth, and other seedlings with poor growth can be pulled out.

3) When the seedlings grow 5-6 true leaves, transplant them in time, and water them immediately after transplanting, and then water them once a day in the morning and once in the evening for 3 days in a row, so as to slow down the seedlings.

5. Prevention and control of diseases

The main diseases of Chinese cabbage are soft rot and root rot, and the main pest is cabbage insects, so the field should be kept at a suitable humidity (slightly dry) during planting, and regular spraying of disinfection and insecticides can achieve the effect of preventing and controlling pests and diseases, and promote the healthy growth of Chinese cabbage.

Chinese cabbage planting methods: variety selection, land preparation and fertilization, sowing management, water and fertilizer management, pest control.

1. Planting time

Chinese cabbage prefers a cold environment, and the suitable temperature for growth is between 15 and 22 degrees Celsius, but at the same time, Chinese cabbage also needs sufficient light to grow. In the north, sowing is usually done around mid-August, while in the south, where the temperature is a little warmer, it is delayed until around September, and early-maturing cabbage varieties are generally selected. Spring Chinese cabbage is generally grown in March and April.

2. Planting method

1.Select the variety

I just mentioned that early-maturing cabbage varieties are generally selected, and then the characteristics are best those with strong resistance to diseases and pests and storage. However, according to the market, if you want to seize the opportunity, you must choose the right variety. Each breed has its own advantages and disadvantages.

2.Fertilization of the land

Ploughing begins about a week before sowing, and basal fertilizer is applied to the soil at the same time. Generally, about 5,000 kg of well-rotted organic fertilizer is used per mu, and about 60 kg of ternary compound fertilizer is used.

3.Seeding management

Sowing can choose strip sowing or hole sowing, the amount of seed per mu is about 150 to 250 grams, according to the variety of cabbage to determine the number of plants in the field, generally straight cabbage per mu planting 3500 plants, hugging type per mu and then about 2500 plants.

4.Water and fertilizer management

In terms of watering, it is necessary to pay attention to the growth stage of cabbage, and the water demand of cabbage in the early stage is average, and the soil can be kept moist. After the cabbage enters the rosette stage, it is necessary to properly control the water to promote the cabbage to bulb and prevent growth. Chinese cabbage has a very large demand for nitrogen fertilizer, followed by potassium fertilizer.

The uptake of nitrogen fertilizer was mainly concentrated in the rosette stage of cabbage, and the uptake of potassium fertilizer began to increase after entering the bulbous stage.

5.Pest and disease control

In the early stage of anthrax, spray with 50% carbendazim 500 times, or polyoxymycin 1000 times, or 40% polysulfur suspension 600 times, or 80% anthrax Fumei 800 times, spray once every 7 10 days, and spray 2 3 times in a row. The main comprehensive control measures of cabbage insects are mainly chemical control.

The Chinese cabbage planting method is as follows:

1. Land selection and land preparation.

Chinese cabbage should not be cropped continuously, and the ground cultivation of early beans, early peppers, early cucumbers, and early tomatoes can be selected before stubble. The ground where Chinese cabbage is planted is applied with enough rotted organic matter fertilizer as base fertilizer, deep ploughing, and then the land is broken and leveled to make a rice-wide furrow, or a narrow furrow or a high furrow of rice.

2. Sow seeds. Early-maturing varieties are generally sown in early to mid-August, and some are sown as early as late July. Medium-ripening varieties can be sown in late August to early September.

Late-maturing varieties should be sown in late August. The spacing between rows and plants should be determined according to the different varieties. Generally, the early-maturing varieties are 33-50 33 cm, with 2100-2300 seedlings per mu, and the late-maturing varieties are 67*50 cm, with less than 2000 seedlings per mu.

3. Field management.

When the Chinese cabbage has 2-3 true leaves, the first seedling is thinned; 5-6 leaves at the time of the second seedling; 7-8 leaves can be set seedlings. According to different varieties, different row plant spacing is selected, and 1 strong seedling is left in each hole. Seedlings can be combined with weeding.

According to the fertility of the soil, appropriate top dressing, with large manure water as the best fertilizer, according to the soil moisture for watering, in the rain when it is more to pay attention to field drainage.

4. Pest control.

The main diseases of Chinese cabbage are downy mildew, black spot, and soft rot. It is necessary to detect and prevent disease as early as possible, and remove diseased strains in time to reduce the source of bacteria and prevent the spread. Insect pests include aphids, cabbage worms, etc., which can be controlled by spraying 1000 1500 times of cypermethrin with high efficiency.

Strict extermination of aphids to prevent the occurrence of viral diseases.
