Fertilizing method for reducing arginine content of mulberry branches

Abstract

The invention provides a fertilizing method for reducing arginine content of mulberry twigs. The mulberry trees are fertilized by any one of the following four schemes: 1) applying 100kg of compound fertilizer and 150kg of organic fertilizer per mu; (2) applying 100kg of compound fertilizer, 150kg of organic fertilizer and 50kg of calcium-magnesium fertilizer per mu; 3) applying 100kg of compound fertilizer, 150kg of organic fertilizer and 1.0 kg of boric fertilizer per mu; 4, 100 kg of compound fertilizer, 150 kg of organic fertilizer, 50 kg of calcium magnesium fertilizer and 1.0 kg of boric fertilizer are applied per mu. According to the invention, accumulation of free amino acids and inorganic nitrogen elements is controlled by selecting reasonable types, proportions and fertilization periods of fertilizers or compounding or cooperatively using a plurality of fertilizers, so that the purpose of reducing the arginine content of mulberry twigs is achieved.

Description

technical field [0001] The invention relates to a fertilization method for reducing the arginine content of mulberry branches, and belongs to the technical field of medicinal plant cultivation. Background technique [0002] Fertilization can provide comprehensive and sufficient nutrition for mulberry trees and effectively increase the yield of mulberry trees. Therefore, it is necessary to balance fertilization according to the growth status and nutrient requirements of the trees. Studies have shown that the total nitrogen content in leaves, branches and roots of different varieties of mulberry trees has a very significant increase after applying a single nitrogen fertilizer. From the perspective of nitrogen distribution in various parts of the plant, the total nitrogen content is in the form of leaves>roots>branches. Compared with the no-nitrogen treatment, the nitrogen concentration in all parts of the plant increased when the nitrogen supply level increased, indicati...

[0003] The purpose of traditional mulberry tree planting is to pick leaves and raise silkworms. The yield and quality of leaves are the most concerned content of silkworm farmers in cultivation. Since silk is also protein, it is transformed from silkworms eating mulberry leaves. The nitrogen content in mulberry leaves is a measure of the quality of mulberry leaves. Therefore, in actual cultivation, partial application of nitrogen fertilizer is often caused
