Every autumn and winter, every household in the countryside will plant some Chinese cabbage. Especially in the north, it is a wintering way to eat Chinese cabbage. Chinese cabbage is a very important vegetable variety in our life. Below, we will talk about the cultivation techniques of Chinese cabbage.
First, land selection and land preparation
If Chinese cabbage is continuously planted, it is very easy to develop, so it is necessary to carry out crop rotation. The best thing is to use crops and vegetables in the field. If it is only used as a vegetable field, do not use other cruciferous vegetables. It is best to use vegetables such as beans, peppers, and cucumbers. The land of Chinese cabbage should be deeply ploughed for 20 to 27 centimeters for 10 to 15 days, and then the land is broken and leveled to make a scorpion of 1.3 to 1.7 m wide, or a narrow sorghum or sorghum of 0.8 m. When doing sputum, it is necessary to deepen the sulcus and the gutter, and the ditch is more than 27 cm, so that the ditch and the ditch can communicate.
Second, the seeding method
In addition to early spring and summer, cabbage can be directly planted for cultivation of seedlings. Others are best to choose water and fertilizer, well-drained land as a nursery field, and then clean the harvested vegetable garden and flatten the highland. Let it dry. When planting, you can use uniform sowing or dilution sowing, and pay attention to the prevention and control of pests and diseases, timely topdressing and watering. Generally, it can be transplanted after 25~30 days after sowing. Planting in early autumn and deep planting in late autumn can improve the anti-freezing ability of Chinese cabbage.
Third, fertilization management
The roots of Chinese cabbage are shallow and the absorption capacity is weak. The fertilizer should be continuously supplied during the growth period. The repeated application of quick-acting nitrogen fertilizer is an important measure to promote the growth of cabbage and ensure high yield. The principle of rational fertilization: First, timely topdressing after planting, promote seedlings to restore growth; second, with the growth of cabbage, increase the concentration and dosage of topdressing. As for the method, period and dosage of fertilization, it depends on weather, seedlings, soil, etc. Watering is combined with topdressing. Do not be short of water within 3~5 days after planting, especially in summer and early autumn. After planting, it should be watered for 3~4 days in the morning and evening. The cultivated cabbage should be applied with organic fertilizer as the base fertilizer. When the fertilizer is properly applied during the growth period, it can also be combined with sprinkler irrigation for foliar topdressing. For example, the sugar-alcoholic calcium foliar fertilizer is a fertilizer for calcium supplementation.
Fourth, pest control
For the disease "black spot" that often occurs on Chinese cabbage, a black moldy body can harm other Chinese cabbage by airflow, or it can spread through the link between the leaves, so that the cabbage leaves can be made from the inside out. The death of the dead, will cause a great economic loss, black mold can be attached to the Chinese cabbage seeds, directly harm the seedlings, so seeded with 50% of the weight of the seeds of 0.2% to 0.3% of the eucalyptus wettable powder. If there is a hazard during growth, you can use 75% chlorothalonil WP 600 times solution, or 50% phlegm WP 1500 times solution, spray with additives for two to four times to be effective. In addition, we must control the humidity in the field, do a good job of ventilation in the field, and avoid water accumulation in the field.
Precautions:
1 easy to disease plot. With the cruciferous vegetable flail and the neighboring land, the land that has not been seeded and planted, the land that has been planted too early, the field where the plant density is large, the land with insufficient base fertilizer and top dressing, the land where the plant grows weak, the big water The land that is flooded is easy to develop.
2 vulnerable vegetables. In addition to Chinese cabbage, radish, broccoli, rape (cabbage or green vegetables), broccoli (cauliflower), etc., are susceptible to the disease, so please beware.
The above is the key points of planting technology of Chinese cabbage compiled by Huinong. The above-mentioned pharmaceutical solutions are for reference only and I hope to help everyone.
