Hybrid cotton has a large row spacing and generally has a row width of 100 cm or more. Before the closure of the line, there is a time and space of about 60 days to develop a crop of vegetables. You can choose to plant summer cabbage. The symbiotic period of cotton and Chinese cabbage in summer is short, and the effect is quick. The symbiosis period is generally 50 to 60 days, and the yield is more than 1,000 kilograms per kilogram of Chinese cabbage. Second, the variety of Xiabai cabbage that has been bred is increased, which is resistant to heat, disease, and humidity. Strong light ability, great choice; Third, it can fill the market demand for Chinese cabbage, market circulation. Supporting planting techniques must grasp the following points. First, force to avoid heavy planting. In Daejeon, where the cross-species crops were planted in the previous year or the same year, even if the cotton spacing is wider, it is not appropriate to cover the summer-harvest Chinese cabbage because it may result in the lack of certain nutrient elements in the soil, and it may induce certain diseases. It is best to use the spring flower field planting without front crops. Second, choose the right variety. Cotton can be used in the hybrid, E Za, Xiangza, Suza, Miscellaneous series of related hybrids. Heat-resistant Chinese cabbage can be used in new Xiayang Baoxin white, early maturity on the 5th, Huayang white, Yuwang 55, heat resistance, white 45, Xiafeng, Xia Lu, Zhengshu No. 1 and so on. Third, determine the reasonable density. Cotton box width (including ditch) 1.5 to 2.0 meters, each type of two rows of cotton, density per acre of 1600 to 1800 strains, high fertilizer levels of about 1200 per acre. Wide-line cotton sowing or planting two rows of cabbage, 2000 to 2500 per mu. Fourth, scientific supporting management. Due to the short growing period of summer Chinese cabbage, the absorption of fertilizer is rapid, and the transformation is fast. Firstly, a fully decomposed organic fertilizer should be used as the base fertilizer in the wide cotton line. One kilogram of yeast is added per 1500 kilograms; the second is to make Chinese cabbage seedlings 5 On the 10th to the 15th of the month, planting is completed to ensure that the Chinese cabbage is harvested before the closure of the line; 3 to the Chinese cabbage seedlings 4 to 5 true leaves when chasing a clear water manure, before closing the line to catch 10 kg of urea per mu, the ball mid-ball each Mu recovery urea 9 to 10 kg, and can be sprayed Hui Man Fung active liquid fertilizer 1 to 2 times, the concentration of 800 to 1000 times the liquid; four to prevent pests and diseases, can spray K prime plant life peptide 800 to 1000 times liquid once.
