The latest aubergine excessive growth causes and prevention measures

First of all, it needs to raise seedlings when planting eggplant, and the phenomenon of excessive growth of eggplant is very easy to occur in the process of growing eggplant, which is not conducive to the formation of strong eggplant seedlings, resulting in unsmooth cultivation in the later stage, which directly affects the yield. So what is the reason for the excessive growth of eggplant? How to prevent it? Let's get to know it.

1. Eggplant overgrowth harm

Because the cuticular layer on the surface of the stem and leaf is underdeveloped and the water evaporation is large, eggplant is easy to wilt due to wind and water loss; the content of nitrogen in the plant is high and the content of carbohydrate is low, which results in poor stress resistance and is prone to disease. The excessive growth of eggplant seedlings causes malnutrition, which can easily lead to late flower bud differentiation, a small number of flower buds, abnormal floral organ development, abnormal fruit or stiff fruit, and slow after planting, and the survival rate is low.

2. The reason for the excessive growth of eggplant

There are many reasons for eggplant overgrowth, and the most likely period of eggplant overgrowth is in the period of cotyledon expansion of seedling branches, which is mainly due to over-dense sowing and failure to remove the mulch in time after the seedlings are unearthed, resulting in overcrowding of seedlings. If the temperature is not cooled in time after emergence, the phenomenon of overgrowth is also very easy to occur. In the cotyledon expansion period, the seedlings are too crowded or overheated, which will also cause the seedlings to grow too much. Before slow seedling planting, because of continuous overcast and rainy days, the humidity of the seedling bed is higher, and the nitrogen fertilizer is too much, which is also very easy to cause overgrowth.

3. Preventive measures

Under the premise of ensuring the suitable temperature of the seedling bed, the mulch should be removed in time to prolong the natural light duration of the seedling bed as far as possible, so that the light of the seedling bed is sufficient and the seedling growth is restrained. At the same time, it is necessary to appropriately reduce the seedbed temperature, when half of the seedlings in the seedbed are unearthed, it is necessary to reduce the daytime temperature to 25 degrees in time, and the night temperature should not exceed 15 degrees. Because the seedlings are crowded and overgrown due to the excessive density of seedlings, the seedling spacing should be thinned as soon as possible, at the same time, the management of seedling bed should be strengthened, and foliar fertilizer should be sprayed in time to supplement seedling nutrients. For those who grow and grow, they can also be foliar sprayed with growth regulators such as dwarfin to inhibit overgrowth.
