Summer cabbage cultivation has a coup

     Sowing at the right time. The heat-tolerant summer Chinese cabbage variety is weak in winter, the early sowing is easy to convulsion early, and the ball is small at the same time; the sowing date is too late to achieve the purpose of increasing production and increasing efficiency. Generally, it can be planted in stages from May to July. Seeding with new high-fat membrane before planting can keep warm, moisturize and swell, improve seed germination rate and make seedlings strong. Repel underground pests and isolate viral infections. It can also be mixed with a seed coating.

Scientific topdressing. Topdressing should be done a small number of times. Generally, the appropriate amount of fertilization is applied in the seedling stage and after the seedling. During the rosette stage and the beginning of the ball, the bio-organic fertilizer and the appropriate amount of high-nitrogen compound fertilizer are applied on both sides of the ditch, and the vegetable Zhuanglingling and the new high-fat film are sprayed to activate the plant ecological growth positive energy, broaden the plant conduit path and enhance the plant. Absorb water and absorb fertilizer to increase production and quality.

Pest control. To prevent viral diseases, it is necessary to strengthen the watering and waterlogging during the seedling stage, timely eliminate the weeding and spray a new high-fat film 600 times to form a polymer film, and cut off the transmission route. The diseased plants were found to be cleared in time. The heartburn is caused by high temperature and drought, and the management of fertilizer and water should be strengthened.
