What causes stunted eggplant seedlings? A full analysis of prevention and control methods
Eggplant is a familiar vegetable, and during winter seedling raising, growers often encounter the phenomenon of stunted seedlings. After eggplant seedlings become stunted, the stems are thin and soft, the leaves are small and yellow, and the roots are few and dark. After transplanting, they are slow to produce new roots, grow slowly, flower and fruit late, and are very prone to early aging. So what causes stunted eggplant seedlings? Let's find out together.
1. Effects of temperature and light
During the eggplant seedling stage, if it encounters an environment of high temperature and high humidity along with insufficient light, plant growth will be slowed, and the plants will also be weakened and poorly developed, without sufficient nutrients to support flowering and fruiting, and stunted fruit is also very likely to occur.
Prevention and control methods: Throughout the entire growth period of eggplant, temperature must be well controlled. Generally, keep it below 30 degrees during the day, and it should not exceed 35 degrees; at night, keep it between 15-20, and it must not be lower than 14 degrees. Especially before and after flowering, if rainy weather occurs, drainage and waterlogging prevention should be strengthened, and light intensity should be appropriately increased.
2. Insufficient water
During the eggplant seedling stage, a certain amount of water is also needed for growth. If there is long-term drought and water shortage, the quality of seedling recovery is poor, the plants grow poorly, and after transplanting, stunted seedlings are very likely to appear.
Prevention and control methods: During the seedling stage, suitable moisture conditions should be maintained to promote normal growth of the seedlings, but do not water too much, so as to avoid water accumulation and root rotting. Watering should be even and thorough, and attention should be paid to drainage on rainy days.
3. Improper fertilization
During the eggplant seedling stage, when sufficient base fertilizer has been applied, generally no additional fertilization is needed during the seedling stage. If too much nitrogen fertilizer is applied, it will cause the seedlings to grow excessively, and in the later stage, stunted seedlings are very likely to occur.
Prevention and control methods: Correct fertilization techniques must be mastered when fertilizing. Choose fully decomposed organic fertilizer as the base fertilizer, and the base fertilizer must be applied in sufficient amount. In the later stage of growth, attention should be paid to the reasonable combined application of nitrogen, phosphorus, and potassium fertilizers. In addition, attention should also be paid to the supplementation of trace elements such as calcium.
