Abstract

The invention relates to suspension liquid fertilizer for root promotion and seedling raising, and a preparation method and applications thereof. The liquid fertilizer includes large amount of elemental fertilizer, compound trace element fertilizer and humic acid, and is characterized in that the liquid fertilizer also includes potassium dihydrogen phosphite, fish protein and a plant growth regulator; the mass ratio of the potassium dihydrogen phosphite to the fish protein is (3-5) : 8; the mass ratio of the potassium dihydrogen phosphite to the plant growth regulator is 1,000-2,500 : 1; and the plant growth regulator is a composition of naphthylacetic acid, indol butyric acid and kinetin. The preparation method and applications of the suspension liquid fertilizer for root promotion and seedling raising are also provided. The suspension liquid fertilizer is high and complete in content, low in cost and good in stability and dissolvability; and the suspension liquid fertilizer can promote the formation of soil aggregate structures, enhance soil permeability, promote root development and rapid seedling raising of crops, strengthen the efficient absorption of nutrients by crops and promote crop yield increase.

Description

technical field [0001] The invention relates to a root-promoting and seedling-raising suspension-type liquid fertilizer, a preparation method and application thereof, and belongs to the technical field of liquid fertilizers. Background technique [0002] The root system is an important organ for crops to absorb water, nutrients, synthesize amino acids, plant hormones and other physiologically active substances, and promote the growth of aboveground parts. The root biomass, physiological activity and its spatial distribution are the prerequisites for determining its effect. Fertilizer is a very important factor affecting the growth of crop root system, but fertilizer must be dissolved in water before it can be directly absorbed by crops. Traditional solid fertilizer has poor solubility and low utilization rate, forcing farmers to increase the amount of fertilizer used . However, the use of excessive solid fertilizers has led to serious soil quality problems such as secondary...
