Open field eggplant summer management

After the planting of the eggplant, the eggplant was quickly exposed to rain and hot weather in July and August. The eggplant was pleasing to the ground and impatience. This kind of weather caused a great threat to the normal growth of the eggplant, and it also made manual management more difficult. Therefore, the summer management of open eggplant needs special attention to proper water control, rational fertilization, and timely control of pests and diseases.

First, appropriate water control

First of all, in terms of cultivation conditions, sandy loam soils with high topography should be selected as much as possible, and soil moisture should be ensured to ensure normal eggplant growth. 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 â€œroot waterâ€ 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.

Second, rational fertilization

Eggplant grows for a long period of time, so be sure to reapply base 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."

Third, pest control

Summer heat and humidity, eggplant pests and diseases are serious, especially Verticillium wilt and M. blight. 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, with continuous control 2-3 times. Of course, particularly serious plots should be pulled out in time. After removing the diseased plants, fresh lime is used for sterilization.

Because the eggplant is watery and intolerant, it is necessary to do a good job in field management to ensure that there is no stagnant water after the rain, and timely remove diseased leaves and fruit, reduce infections, but also to strengthen the cultivator, increase phosphorus, potash fertilizer, improve Plant disease resistance.
