Abstract

The invention provides a macro-element water-soluble fertilizer containing poly-gamma-glutamic acid. The fertilizer comprises the following ingredients in parts by weight: 10-30 parts of nitrogen fertilizer, 10-20 parts of phosphorus fertilizer, 10-30 parts of potassium fertilizer and 0.1-0.5 part of poly-gamma-glutamic acid, that is, the weight ratio of nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer and poly-gamma-glutamic acid is (10-30):(10-20):(10-30):(0.1-0.5). Under the equal cultivation conditions, the crop yield can be increased by 10-30% when the coated fertilizer is applied, and the fertilizer consumption can be reduced by 10-20%; the fertilizer is used for experimental cultivation of wheat, apples, citruses and the like for several years, and the experimental results show that the fertilizer use cost can be effectively reduced by 30% when poly-glutamic acid is added into the fertilizer, and the fertilizer consumption can be reduced by 20-40%; moreover, the fertilizer provided by the invention is poly-element composite fertilizer which can be completely dissolved in water; due to rapid dissolution in water, the fertilizer can be absorbed by crops more easily, and the fertilizer absorption and utilization rate is relatively high; more importantly, the fertilizer can be applied to facility agriculture such as spray irrigation and drop irrigation, the water-fertilizer integration is realized, and the efficacies on water, fertilizer and labor conservation are achieved.

Description

technical field [0001] The invention relates to the field of liquid fertilizers, in particular to a poly-γ-glutamic acid-containing macroelement water-soluble fertilizer and a preparation method thereof. Background technique [0002] Polyglutamic acid can be used as a drug carrier, and has the characteristics of biodegradability, no toxic side effects, and good biocompatibility. Due to its strong moisturizing properties, polyglutamic acid can be used to develop facial masks and lotions in the field of cosmetics and daily chemical products. As a biopolymer flocculant, polyglutamic acid can be used to adsorb metals and radioactive substances, so it is also used in the field of environmental protection. In the field of agriculture, polyglutamic acid can be used as a soil conditioner and a water-retaining agent for plants, as well as a slow-release agent for pesticides and fertilizers. In the food field, the antifreeze activity of polyglutamic acid is significantly higher than...
