Fertilization application method for improving yield and quality of bitter gourds

Abstract

The invention discloses a fertilization application method for improving the yield and quality of bitter gourds. The content of various nutrients of soil available nitrogen, phosphorus and potassium is combined, and a fertilizer is applied in batches according to the formula amount of the fertilizer. The method comprises the following steps of: applying a base fertilizer within 3 to 7 days before the bitter gourds are transplanted; and applying a fertilizer for the first time on the 7th to 15th day after transplantation, applying the fertilizer for the second time after 7 to 15 days, applying the fertilizer for the third time after 7 to 15 days, and applying once every 10 to 15 days subsequently, wherein the fertilizer is applied for 6 to 8 times in total after transplantation. In the method, the fertilizer is scientifically and reasonably applied according to the nutrient condition of the nitrogen, phosphorus and potassium of the soil, fertilizer requirement laws of different crops and agricultural production requirements, and various nutrient elements such as nitrogen, phosphorus and potassium are reasonably proportioned by soil testing and formulated fertilization so as to ensure that the absorption of three elements, namely nitrogen, phosphorus and potassium is basically balanced with the growth of plant biomass, so that the yield and quality of the bitter gourds are improved, and the economic benefit is increased.

Description

technical field [0001] The invention relates to the technical field of vegetable fertilization, in particular to a fertilization method for improving the output and quality of bitter gourd. Background technique [0002] At present, there are common problems of blind and excessive fertilization in vegetable production, and the application of chemical fertilizers is often partial to nitrogen and light in phosphorus and potassium. Excessive fertilization leads to environmental pollution of water bodies and deterioration of agricultural product quality, or the imbalance of crop nutrients caused by blind fertilization causes diseases and increased pests, resulting in increased pesticide input and environmental pollution. Soil testing and formula fertilization is to determine the type, ratio and amount of fertilizer to be applied according to the soil fertilizer supply status and the characteristics of crop fertilizer demand. At the same time, due to the robust growth of crops an...

AI Technical Summary

Problems solved by technology

Nitrogen, phosphorus and potassium each play an important role in the formation of bitter gourd yields. There are differences in the absorption of nitrogen, phosphorus and potassium by crops at different growth stages, and there are three kinds of element balance problems. For a long time, bitter gourd There is a phenomenon of blind fertilization in production. The amount of nitrogen fertilizer application is large, and the amount of phosphorus and potassium fertilizer is small, resulting in low yield and poor quality of bitter gourd. Moreover, bitter gourd is widely planted in the south. Therefore, it is necessary to study the amount and method of fertilization of bitter gourd according to soil characteristics.
