May is the high yield period of eggplant. It is particularly important to do well in field management. How to master a set of high-quality management skills is worth discussing here for a large number of vegetable farmers. Recently, the reporter contacted Liu Jianhui, a professor at the College of Horticulture at the Northwest Agriculture and Forestry University. He asked the vegetable farmers about the problems of water, fertilizer and pest control.
"Water and fertilizer is full," the first source of good eggplant hi water, the demand for fertilizer and water is very large, only to ensure adequate water and fertilizer supply in order to effectively prevent the occurrence of disease. Liu Jianhui said that it is an important process to maximize the maintenance of adequate soil moisture. After the ditch is filled with water, 15-30 kg of acre per acre will have a concentration of 0.3% of ammonium bicarbonate, 10 kg of 0.15% of monoammonium phosphate and 10 kg of ammonia. The concentration of 0.2% potassium sulfate is evenly sprinkled in the ditch to ensure that the eggplant absorbs nutrients completely. "If there is no shortage of water in the field, you can dig a nest in the middle of every four eggplants and put it into a fully decomposed farmyard fertilizer. After top-dressing, you should increase the amount of ventilation and prevent the effects of fertilizer damage," said Liu Jianhui, adding that at the same time, Soil permeability, reduce soil temperature, timely removal of axillary buds, keep the plant's bottom two largest leaves, all other old leaves removed.
Focus on the prevention and control of M. occidentis under high temperature and high humidity In May, eggplant prone to M. blight and powdery mildew, especially the M. blight disease. If the eggplant is infected with M. mori, it will grow long and dense white hair. The eggplant will also decay quickly. Liu Jianhui suggested that once the disease is found, the central disease strain should be quickly removed and destroyed, and immediately use 75% chlorothalonil 500 to 600 times, 50% thiophanate-methyl WP 800 times, and 40% ethoxyphos aluminum WP 200 times liquid, 64% antiviral 500 times liquid and other mixed pharmaceuticals are sprayed, sprayed once every 10 days or so, sprayed 3 to 4 times, and used together with guatica fruit plant protection products to achieve Better control effect.
