May is the high-yield period of eggplant. It is especially important to do field management. How to master a set of high-quality management skills is worthy of discussion for the majority of vegetable farmers. Recently, the reporter contacted Liu Jianhui, a professor at the College of Horticulture of Northwest A&F University, to take care of the veins and support for the problems of water, fertilizer and pest control. Â "Water and foot fullness" puts the source of the first source of eggplant water, the demand for fertilizer water is very large, only to ensure adequate supply of water and fertilizer, can effectively prevent the occurrence of disease. Liu Jianhui said that it is an important process to maintain sufficient soil moisture to maximize the amount of water. After the ditch is filled with water, the concentration of 15-30 kg per acre is 0.3% of ammonium bicarbonate, 10 kg of 0.15% of monoammonium phosphate and 10 kg. The concentration of 0.2% potassium sulfate is evenly sprinkled in the ditch to ensure that the eggplant absorbs the nutrients completely. "If there is no shortage of water in the field, you can dig a nest between each of the four eggplants and put in a fully decomposed farmyard manure. After topdressing, you should increase the ventilation and prevent the effects of fertilizer damage." Liu Jianhui said, at the same time, increase Soil permeability, lower soil temperature, timely removal of axillary buds, retaining the largest two leaves in the lower part of the plant, and all other old leaves are removed. Â Focus on prevention and control of cotton blight in high temperature and high humidity in May, eggplant is prone to plague and powdery mildew, especially the plague disease is the most prominent. If the eggplant is infected by the plague, it will grow long and dense white hair. Eggplant will also rot quickly. Liu Jianhui suggested that once the disease is discovered, it is necessary to quickly remove and destroy the central diseased plant, immediately use 75% chlorothalonil 500 to 600 times solution, 50% methyl thiophanate WP 800 times solution, 40% ethyl phosphate aluminum WP. 200 times, 500 times 64% alumina and other mixed virus agents to spray, every 10 days, spray, even spray 3 to 4 times, while accompanied by melon eggplant fruit only type commonly used plant protection products, in order to achieve Better control effect.
