The latest course on management techniques and methods of summer eggplant in open field

Eggplant is a kind of vegetable that many people like to eat very much. Eggplant is rich in nutrients and has a large market demand in our country. After entering the summer, it is almost the peak season of eggplant. In order to ensure the normal growth of eggplant and expand the planting efficiency, we must do a good job in the management of planting eggplant in summer. So the editor brings you the management technology of summer eggplant in the open field today. Let's take a look at it.

1. Proper watering

In the hot summer environment, we must do a good job of watering. First of all, we should plant summer eggplant on high-lying sandy soil, and the soil should be kept moist to promote the normal growth of eggplant. If the soil water content is insufficient, then the growth rate of eggplant will be reduced, not only the fruit setting rate of eggplant will be reduced, but also the phenomenon of serious flower and fruit drop will appear. Therefore, after the eggplant is planted, we must pour enough water to fix the root to promote the growth of the eggplant root. Then a flood of water should be watered before harvest to promote the expansion of eggplant fruit and keep the soil moist during the growing period.

2. Scientific fertilization

The growth cycle and harvest time of eggplant are relatively long, so the nutrition consumed during the whole growth period is more. Therefore, we must pay attention to do a good job of fertilization, in addition to the application of sufficient base fertilizer, but also do a good job of topdressing. The demand for nitrogen fertilizer in the growth of eggplant is relatively large, but it is necessary to control the application rate in summer. Then is to pay attention to control the use of ammonia, should not be too much. Because the high temperature in summer will accelerate the volatilization of ammonia, eggplant is prone to ammonia poisoning. Finally, we should do a good job of foliar topdressing, but to control the concentration to avoid counterproductive.

3. Pest control

The high temperature and humidity environment in summer can also easily cause the occurrence of many diseases and insect pests, such as Verticillium wilt, cotton blight and so on. These diseases will have a serious impact on the growth of eggplant, light will lead to a reduction in yield, heavy will lead to no harvest. Therefore, we must do a good job in the prevention of diseases and insect pests, strengthen management, control the amount of watering and fertilization, and ensure that eggplant can grow healthily. After finding that the eggplant is abnormal, it is necessary to check the specific cause in time, and then make the corresponding treatment according to the actual situation.

4. Other management

When we plant eggplant in summer, we should also pay attention to the basic work such as weeding and pruning. Proper weeding can avoid too many weeds, lead to uneven nutrition absorption of eggplant and reduce the fruit setting rate of eggplant. And we also need to do a good job of pruning according to the eggplant, cutting off the branches that are too long and too dense. It can not only reduce nutrition consumption, but also improve field permeability and ensure the healthy growth of eggplant. Finally, we should pay attention to the field moisture should not be too much, because eggplant is not resistant to waterlogging, must be timely drainage after rain, to avoid retting root and fruit phenomenon.

The above is a brief introduction to the management technology of summer eggplant in the open field. Although it is common to plant eggplant in summer, because of the season, we must pay attention to the management to ensure the yield of eggplant. That's all for today's introduction.
