A kind of growth-promoting stable and synergistic water-soluble fertilizer

Abstract

The invention relates to a water soluble fertilizer and a preparation method, in particular to a growth-promoting stable and synergistic water soluble fertilizer and a preparation method. The water soluble fertilizer comprises the following components in percentage by weight: 10-50 percent of urea, 10-40 percent of ammonium nitrogen fertilizer, 10-30 percent of water soluble phosphorous fertilizer, 15-30 percent of water soluble potassium fertilizer, 0.5-10.0 percent of water soluble secondary elements, 0.1-8.0 percent of water soluble trace elements, 0.1-3 percent of fertilizer synergist, 0.01-10.0 percent of plant growth promoter, 0.01-10.0 percent of nitrogen stabilizer and 0-10 percent of water soluble additive, wherein the water soluble additive is a water soluble amino acid chelate and / or water soluble humic acid. The utilization ratio of the fertilizer can be increased by 60-100 percent compared with the conventional ordinary water soluble fertilizer, and the fertilizer effect can last for 120 days in maximum. Compared with an ordinary water soluble fertilizer, the growth-promoting stable and synergistic water soluble fertilizer has the advantages that the crop yield is increased by 20-60 percent by applying the same amount of fertilizer; the fertilizer can be saved by 20-40 percent at the same yield.

Description

technical field [0001] The invention relates to a water-soluble fertilizer and a preparation method thereof, in particular to a growth-promoting, stable and synergistic water-soluble fertilizer. Background technique [0002] With the continuous increase of human demand for food and the continuous consumption of natural resources, the area of ​​arable land available to humans is continuously decreasing, and the fertilizer resources and raw materials that can be mined and synthesized are continuously decreasing, making humans need to produce more per unit area of ​​arable land. crops or food products. In order to increase the crop yield per unit area, human beings continue to develop the use of dry and less rainy land, establish irrigation facilities in these areas and the original rain-fed agricultural areas, carry out irrigation and cultivation techniques such as drip irrigation and sprinkler irrigation, and adopt integrated water and fertilizer technology to achieve fertili...

Problems solved by technology

[0003] The current existing water-soluble fertilizer technology has many defects: if the nutrients contained are not comprehensive, it cannot supplement organic nutrients or organic matter for crops or soil, the effective nutrient content is low, and the nutrient structure is unreasonable, so it cannot provide balanced nutrients for crops. The active ingredients in the soil are not stable, and are easily leached or lost by volatilization. After being applied to the soil, it does not increase the efficiency of the fertilizer, maintain the stability of the fertilizer in the soil, promote the growth of the crop, and enhance the stress resistance of the crop. essential nutrients

In this way, the utilization rate of water-soluble fertilizers cannot be improved as it should be.
