Eggplant is watery and intolerant, but after the planting, it quickly encounters rain and heat in the same season in July and August. This weather poses a great threat to the normal growth of eggplant and also makes manual management more difficult. Recently, many vegetable farmers have called this newspaper to inquire about how to manage eggplant in the open field. In response, this reporter interviewed a member of the expert advisory board of the newspaper and Professor Zou Zhirong, a horticultural expert of Northwest A&F University. He pointed out that the summer management of open eggplant needs special attention to the following three aspects: proper water control, rational fertilization, and timely prevention and control of pests and diseases.

Appropriate control of water first in the cultivation conditions, should try to choose a high-lying sandy loam soil cultivation, and to ensure that the soil is wet to ensure the normal growth of eggplant. When the soil moisture is insufficient, the plants will grow slowly and cause fruit drop and fruit drop. Therefore, when rooting, it is necessary to pour “root water†so that the root can grow rapidly, and it should be re-watered once in the early stage of harvest to promote the rapid expansion of the fruit. During the middle growth stage, the soil can be kept moist.
Reasonable fertilization Eggplant grows for a long period of time, so be sure to reapply basal fertilizer and top-dressing. Eggplant requires a large amount of nitrogen fertilizer, but it should not be used excessively in hot season. "A lot of vegetable growers will be combined with irrigation in the topdressing of ammonia fertilizers. In fact, in the hot season, this method is not ideal." Zou Zhirong said that because of the excessively high temperature, ammonia will not only cause volatilization, but also may cause eggplant. Ammonia poisoning, so it is recommended to use open trenches. "The leaf surface of eggplant is large. It is advisable to carry out dressing on the foliage if necessary. Potassium dihydrogen phosphate is effective, but it is necessary to control the concentration."
Timely prevention and control of pests and diseases in summer, high temperature and humidity, eggplant pests and diseases are serious, especially verticillium wilt and cotton blight serious. Verticillium wilt, commonly known as "half madness," is one of the major diseases of open field eggplant. Zou Zhirong said that the most direct way to treat Verticillium wilt is to use Toruubam as the rootstock at the seedling stage and to solve it by grafting. For the diseased plants, 77% of the WP 800-1000 can be used to irrigate the roots, usually about 10 days, and 2 to 3 times of continuous treatment can be used. Of course, particularly serious plots should be pulled out in time. After removing the diseased plants, fresh lime is used for sterilization.
Eggplant Mushroom Disease is also known as "rotten eggplant." The disease mainly harms the fruit, and the fruits on the ground are first infected and gradually spread upward. Therefore, we must do a good job in field management, to ensure that there is no stagnant water after the rain, and timely removal of diseased leaves, disease, reduce infection, but also to strengthen the cultivator, increase phosphorus, potash fertilizer, improve plant resistance. At the beginning of the disease, 69% Anke manganese zinc wettable powder was used. At the same time, the amount of spray on the ground, the base of the stem, and the branches and leaves was increased. This will help improve the control effect. (Reporter intern reporter Zhang Na)
