Causes and solutions of premature senescence of eggplant

Eggplant grows vigorously in the growing period and produces a large amount of fruit, but it is easy to appear premature senescence in the later stage of growth, which has a bad effect on yield and quality. So what should eggplant do when it appears premature senility? Don't worry, let's take a look at the solutions to the premature senility of eggplant with the editor.

1. Performance of premature senility

In the middle and later stage of growth, the root system begins to age, the ability to absorb nutrients is weakened, the growth node is more and more loved, the height of the surrounding leaves exceeds the growth point, the overall growth of the seedling is getting weaker and weaker, and the leaves become more and more yellow and lack of luster. In the later stage, eggplant can not sit on the fruit, the color is dim, the speed of fruit expansion becomes slower, and even the eggplant fruit stops expanding.

2. Causes of premature senility

There are many reasons for premature senescence of eggplant, on the whole, it is caused by temperature and fertilizer and water. When the seedlings are raised with high temperature and humidity, without shading and cooling harvesting, the stems and leaves of the seedlings grow too long, which is easy to lead to poor root development, resulting in the loss of absorptive capacity in the later stage. The application of a large amount of chemical fertilizer, especially nitrogen fertilizer, will also aggravate the phenomenon of overgrowth, stimulate the growth of stems and leaves, poor root growth and weak absorption. After planting, the application of a large amount of chemical fertilizer will also grow in the depth and breadth of the root system, and the root system is underdeveloped, affecting the absorption function. In the middle ploughing and weeding, the depth of cultivated land is shallow, coupled with the application of a large amount of Ah Hu Fei, which destroys the soil structure, resulting in serious soil consolidation and shallow plough bottom, which will also affect the root development and can not absorb enough nutrients for aboveground growth.

3. Solution

In the middle and later stage of eggplant growth, the root absorption is weak, which can be supplemented by foliar fertilizer, and the problem of short plant growth point can be alleviated by plant stress resistance. In addition, it is necessary to add fertilizer and water management, irrigate empty water to alleviate plant roots, and on the other hand, to stimulate rooting, you can use boron and zinc fertilizer to stimulate, once every 7-10 days, twice in a row.

The above is the introduction of the causes and solutions of premature senility of eggplant. I hope it can help you. If you want to know more about it, please follow us.
