Secondly, avoid partial application of nitrogen fertilizer. Manure is the main base fertilizer, and the content of nitrogen fertilizer is the highest, while the content of phosphorus and potassium fertilizer is low. The excessive application of manure makes the nitrogen nutrition in the soil surplus before and after planting, or the application of nitrogen-containing substances after planting leads to excessive vegetative growth of plants and affects reproductive growth.
Finally, avoid watering too often. Eggplant vegetables, such as peppers, should not be watered too often after planting. Usually, after the first watering, water the seedlings for the second time every five days or so. After that, it is not allowed to water more until the first ear or fruit is set. Water control is the main method, and amino acids, chitin and alginic acid products can be combined with slow seedling water to improve plant stress resistance.
