The cause of the latest weak eggplant and its solution

Eggplant is very easy to appear weak alternative in the process of planting, at this time, a common physiological disease, weak tree refers to the weak vegetative growth of branches, must be small branches and leaves, short internodes of stems, slow growth. Weak trees tend to blossom and bear little fruit and yield is low, so what is the reason for the actual occurrence of weak trees? I don't know what to do Let's get to know it with the editor.

First, the reason why eggplant is weak

1. Soil salinization

If the soil is salinized, eggplant root growth environment will be polluted, root growth and development will be seriously inhibited, absorbing very little nutrients and water, so resulting in weak trees.

2. stagnant water in the field

When the high soil water content causes stagnant water, it will lead to eggplant roots can not breathe normally, resulting in hypoxia and asphyxia, then the root absorptive capacity basically disappears, so the plant growth is weak.

3. Excessive fertilization

Many friends in fertilizing too much, or the application of immature organic fertilizer will cause root burning of crops, and root burning will also directly cause weak trees to occur.

II. Solutions

1. Fertilizer and water regulation

In the process of eggplant cultivation, it is necessary to water and fertilize in time, avoid flooding in winter to avoid stagnant water in the field, and appropriately prolong the watering time while keeping the soil moist. Different fertilizers should be selected and applied according to different conditions, and organic manure must be applied after full maturity. For saline-alkalized soil, we can choose to apply biological fertilizer to degrade the concentration of salt ions in the soil and promote root growth.

2. Keep the fruit reasonably

In the process of eggplant cultivation, the plants caused by too many fruits should be thinned in time and fruit should be kept reasonably in order to promote the transfer of plants from reproductive growth to vegetative growth. for individual weak plants, we can choose not to leave fruit for the time being. wait for the plant to grow strong, and then point the flower to leave the fruit.

3. Adjust the temperature

Temperature is an important factor in the growth of absolute eggplant, especially at night, which often leads to low night temperature in winter because of inadequate heat preservation measures, resulting in shorter plant internodes, enhanced reproductive growth and reduced vegetative growth. Therefore, in the daytime, we should try to increase the temperature of the greenhouse and increase the heat preservation facilities to ensure that the night temperature is above 13-15, so as to promote the vegetative growth of the plant.

4. Plant growth regulators

For weak trees, plant growth regulators can be used to assist their growth. Foliar spraying of 600-fold cytokinin, chlorophyll and potassium dihydrogen phosphate can accelerate plant growth and promote vegetative growth.
