Causes and control methods of stiff eggplant seedlings

Eggplant is a familiar vegetable, but the phenomenon of stiff seedlings is often encountered in the process of raising seedlings in winter. Eggplant has thin and soft stems, small and yellow leaves, dark roots, slow growth and late flowering and fruiting after planting. It is extremely easy to age. So what is the reason for the stiff seedlings of eggplant? Let's get to know it.

1. The influence of temperature and light

In the eggplant seedling stage, if it encounters the environment of high temperature, high humidity and insufficient light, it will not only lead to slow plant growth, but also cause plant growth weakness, poor development, lack of sufficient nutrients for flowering and fruiting, and it is also prone to the phenomenon of ossified fruit.

Prevention and control methods: the temperature must be controlled during the whole growth period of eggplant, generally keeping it below 30 degrees during the day, not more than 35 degrees, and 15-20 pairs at night, with a minimum of 14 degrees. Especially before and after flowering, if you encounter cloudy and rainy weather, it is necessary to add drainage and waterlogging, and appropriately increase the light intensity.

2. Lack of water

Eggplant seedling growth also needs a certain amount of water, if long-term drought and lack of water, slow seedling quality is poor, plant growth is poor, it is easy to appear rigid seedling phenomenon after transplanting.

Prevention and control methods: in the seedling stage to maintain suitable water conditions to promote the normal growth of seedlings, but not too much watering, so as not to cause stagnant water retting roots, watering should be evenly watered, thoroughly watered, and drainage should be paid attention to in cloudy and rainy days.

3. Improper fertilization

In the case of applying sufficient basal fertilizer at the seedling stage, eggplant generally does not need to be fertilized at the seedling stage. If excessive nitrogen fertilizer is applied, it will cause the seedlings to grow too long, and it is very easy to cause the phenomenon of rigid seedlings in the later stage.

Prevention and control methods: to apply fertilizer, we must master the correct fertilization technology, choose fully mature organic fertilizer as base fertilizer, apply enough base fertilizer, pay attention to the reasonable combined application of nitrogen, phosphorus and potassium fertilizer in the later stage of growth, and pay attention to the supplement of calcium and other trace elements.
