How to solve the problem of eggplant, pepper, tomato and other solanaceous vegetables that only grow fruit (trees) without fruit?
One, less effective nitrogen fertilizer
During the cultivation process of eggplant, pepper, tomato and so on, especially in the result period, nitrogen fertilizer is often used excessively, resulting in growing over-prosperous, serious flowering and falling fruit, making nutrient overgrowth, and lack of reproductive growth. It is recommended that vegetable growers use less nitrogen fertilizer during the fruiting period of solanaceous vegetables, and the use of amino acid water for fertilization is better, with no more than 40 kg per mu.
Second, nutrition regulation
According to the characteristics of humic acid foliar fertilizers and amino acid foliar fertilizers that can control the growth potential at a certain concentration, combined with disease prevention and pest control, 200-300 times of Gaomei organic humic acid active liquid fertilizer is added, compared to adding propagative nutrients and dwarfism. Hormones and other hormones have good effects, and they are highly pigmented and produce high yields.
Third, the use of gene inducers
Gene-inducing agents have the effect of enhancing physiological metabolism, and increase net photosynthetic rate, reasonably regulate plant height, promote vegetative growth to reproductive growth, and increase yield.
Fourth, cut off the root
When planting solanaceous vegetables, when the plant grows too prosperous, we can use the "scratching method" to weaken the growth. Slugging can increase the permeability of soil on the one hand and reduce the occurrence of soil oxygen deficiency and root rot in the soil due to long-term application of various fertilizers. On the other hand, it can cause some root systems to break off, which is conducive to secondary root barrow. Scratching and cutting roots can reduce the loss of organic nutrients produced by plant leaves and inorganic nutrients in the soil and reduce the growth potential, which is conducive to flower protection and fruit protection.
