First, less application of quick-acting nitrogen fertilizer: vegetables in the cultivation process, especially in the fruiting stage, often due to excessive nitrogen fertilizer, resulting in excessive growth, serious fruit falling. Therefore, it is recommended that the maximum amount of nitrogen fertilizer used by vegetable farmers should not exceed 20 kg per mu, and 800 times of new high-fat film should be sprayed to increase the utilization rate of effective nutrients.
Second, nutrition regulation: can be regularly adjusted using plant growth conditioning agents, spray can promote the flower king 3 to promote the top of the plant nutrient reflux, inhibit the main shoots and promote flower bud differentiation.
Third, slashing the roots: When the growth of vegetable plants is too strong, you can take the "scratch method". On the one hand, it increases the permeability of the soil, on the other hand, it can break some of the root tips, which is conducive to the secondary roots and tie down. In combination with the planing, the new high-fat film 800 times liquid can be sprayed in time to prevent moisture evaporation.
