How to grow cabbage in summer?

How to grow cabbage in summer? Please give a detailed description of the method of summer cabbage planting can refer to the following methods: 1, variety selection. Excellent varieties with high temperature resistance, disease resistance and tight core should be selected, such as Xiayou 2, Xiayang 3, and so on. 2. Apply enough base fertilizer and sow at the right time. After the wheat harvest, we should pay close attention to the removal of wheat stubble. Every 667 meters, 3000-4000 kg of rotten circle fertilizer, 10 kg of potassium sulfate and 10 kg of calcium superphosphate are applied, and the ground is leveled to form a small high ridge about 10 cm high and 50 cm wide. The shallow ditch hole sowing on the ridge, the hole distance between 25cm and 30cm, if it can be covered with black sunshade net after sowing, the seedling emergence rate can be increased. If the land is released late, the seedlings can be raised in a nutrition bowl 15-20 days in advance. The suitable sowing date of summer cabbage is the first and middle of June. 3. Strengthen the field management. After emergence, there should be time seedlings, replenishing seedlings, keeping large seedlings, strong seedlings to weak seedlings, miscellaneous seedlings and small seedlings. From the cross stage, the distance between seedlings was gradually increased, and the seedlings were fixed when cabbage was planted with 5 or 6 leaves. Watering at the seedling stage mastered 3 water to emerge and 5 water to fix the plant. watering 3 water during seedling emergence mainly played the role of preserving soil moisture and cooling, and the 4th and 5th times were inter-seedling water and fixed seedling water. Ploughing immediately after watering or rain. Fertilizer was applied once in combination with fixed seedling water, and 10 kg urea or 15 kg ammonium sulfate was applied and covered with urea or ammonium sulfate every 667 m 2. The fertilizer application point should be 8cm away from the plant and less damage to the roots and leaves. The heart of summer cabbage was watered once in the first 10-15 days, and squatted seedlings after ploughing, so that the growth center changed from outer leaves to leaf balls. When it was observed that the leaves of summer cabbage became thicker and darker, and the edge leaves were green, the squatting seedlings ended. After watering the head water of squatting seedlings, the heart-strengthening fertilizer should be applied again. The type and dosage of fertilizer should be the same as that of plant fertilizer, and fertilizer had better be applied with water. During the whole growing period, the watering quality of summer cabbage has a great influence on its yield and quality, and the lack of water will cause bolting and decrease the yield. Therefore, during the heading period of summer cabbage, special attention should be paid to maintaining sufficient soil moisture, watering in time when the surface is white, and stopping watering 5-7 days before harvest, which is the key to a bumper harvest of summer cabbage. The main diseases are soft rot and virus diseases, and the main pests are cabbage insects and aphids. In addition to chemical control, the base of the stem is not flooded during watering, and the planting density is not too high, which can reduce the occurrence of diseases.
