How to manage planting eggplant in open field in summer? Please refer to the following methods for the management of eggplant in the open field in summer: eggplant likes water and is not resistant to waterlogging, but it will soon encounter hot and rainy weather in the same season in July and August, which poses a great threat to the normal growth of eggplant. It also makes manual management more difficult. Recently, many vegetable farmers have called this newspaper to inquire about the management of eggplant in open field. In this regard, our reporter interviewed Professor Zou Zhirong, a member of our expert advisory panel and an expert in facility horticulture of Northwest University of Agriculture and Forestry. He pointed out that the summer management of eggplant in open field needs to pay special attention to the following three aspects: proper water control, rational fertilization and timely prevention and control of diseases and insect pests. First of all, in terms of cultivation conditions, we should try our best to choose high-lying sandy soil for cultivation, and ensure that the soil is moist in order to ensure the normal growth of eggplant. When the soil moisture is insufficient, it will make the plant grow slowly and cause falling flowers and fruits. Therefore, when setting the root, it is necessary to irrigate the root water enough to make the root grow rapidly, and re-irrigate the root in the early stage of harvest to promote the rapid expansion of the fruit and keep the soil moist in the middle growth stage. Reasonable fertilization eggplant has a long growth period, so it is necessary to re-apply base fertilizer and topdressing in time. Eggplant needs a large amount of nitrogen fertilizer, but it should not be applied too much in high temperature season. "in the topdressing of ammonia fertilizer, many vegetable farmers will be combined with irrigation, in fact, in the hot season, this method is not very ideal." Zou Zhirong said that because too high temperature will not only cause ammonia fertilizer volatilization, but also may cause ammonia poisoning of eggplant, so it is recommended to use trench application. "eggplant has a large leaf surface, so it is suggested that foliar topdressing should be carried out if necessary. Potassium dihydrogen phosphate works well, but attention should be paid to controlling the concentration." Timely control of diseases and insect pests in summer, high temperature and humidity, eggplant diseases and insect pests occurred seriously, especially Verticillium wilt and cotton blight. Verticillium wilt, commonly known as "half crazy", is one of the main diseases of eggplant in open field. Zou Zhirong said that the most direct way to treat Verticillium wilt is to use Torubam as rootstock at the seedling stage and use split grafting to solve the problem. For the plants that have been diseased, 77% of the available wettable powder can be irrigated with 800-1000 times liquid, usually about once every 10 days, and can be prevented and treated continuously for 2 or 3 times. Of course, particularly serious plots should be pulled out in time, and then spread quicklime to sterilize the diseased plants after being removed. Eggplant cotton blight is also known as "rotten eggplant". The disease mainly harms the fruit, and the fruit near the ground gets sick first and spreads upward gradually. Therefore, in the management, it is necessary to do a good job in field drainage, ensure that there is no stagnant water after rain, and timely remove diseased leaves and fruits, reduce infection, strengthen mid-tillage, increase the application of phosphorus and potassium fertilizer, and improve plant disease resistance. At the initial stage of the disease, 69% Anke manganese zinc wettable powder was used, and at the same time, pay attention to spraying more on the ground, stem base, branches and leaves, which is beneficial to improve the control effect.
