Preparation and application of polyaspartic acid liquid fertilizer

Abstract

The invention discloses preparation and application of a polyaspartic acid liquid fertilizer. The polyaspartic acid liquid fertilizer consists of the following raw materials: 50-200ml / L of polyaspartic acid, 10-100g / L of monopotassium phosphate, 100-300g / L of potassium nitrate, 10-100g / L of potassium sulfate, 50-200g / L of biochemical potassium fulvic acid, 10-50g / L of chitosan, 0.1-0.5g / L of boron, 0.01-0.05g / L of copper, 0.1-0.5g / L of iron, 0.1-0.5g / L of manganese, 0.1-0.5g / L of zinc, 0.05-0.1g / L of calcium and the balance of a root protection bacterial solution. The polyaspartic acid liquid fertilizer is free of any plant growth regulating agents or toxic or harmful substances, is applicable to green and safe production of crops, is applied to root irrigation, micro irrigation, drop irrigation, flashing fertilization or leaf fertilization in fruit enlarging periods of fruits and solanaceous vegetables and is capable of promoting absorption of nutrients by crops, increasing the sweetness and the contents of soluble solids and vitamin C of vegetables and fruits, and improving quality and appearance of agricultural products. Moreover, nutrient elements can be activated, chemical fertilizer loss is reduced, the utilization rate of chemical fertilizers is increased by 30% or greater, and the yield of crops is increased by 40% or greater at least.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizers, in particular to the preparation and application of a polyaspartic acid liquid fertilizer. Background technique [0002] Traditional chemical fertilizers are mainly compound fertilizers with relatively single components, mainly containing nitrogen, phosphorus, potassium and a small amount of trace elements. Due to volatilization, leaching and runoff, nutrients cannot be effectively absorbed and utilized by crops. It is only about 35%, and the lost fertilizer causes a large number of non-point source pollution problems such as ammonia volatilization, air pollution, eutrophication of water body, and groundwater pollution. The long-term use of compound fertilizers in large quantities also tends to cause various salts to accumulate in the soil, causing problems such as soil acidification, compaction, and loss of microbial diversity, which seriously damages the nutritional balance of the ...

AI Technical Summary

Problems solved by technology

The patent adds synthetic plant regulators such as diethyl aminohexanoate, cytokinin, and brassinolide. Although it can advance the market time of fruits and vegetables and increase the yield of crops, the quality of fruits and vegetables is significantly different from that of naturally mature fruits and vegetables.
