Fertility-reducing and effect-increasing water soluble fertilizer and preparation method thereof

Abstract

The invention provides a fertility-reducing and effect-increasing water soluble fertilizer and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: 13-19 parts of phosphoric acid, 26-32 parts of urea, 41-47 parts of potassium nitrate, 3-5 parts of calcium chloride, 2-4 parts of amino acids, 2-4 parts of humic acid, 0.3-0.5 part of magnesiumcitrate, 0.4-0.6 part of borax and 0.08-0.12 part of ferrous sulfate. The fertility-reducing and effect-increasing aqueous fertilizer provided by the invention not only is good in water solubility, can be irrigated and drop-irrigated and water the roots to promote the root strong seedlings, so that the crop quality is improved, and also the fertilizer is rich in other nutritional elements such ashumic acid and amino acids, can improve and repair farmlands with successive cropping obstacles effectively, improves the soil fertility, promotes growth and development of crops, and truly achieves the purpose of reducing fertility and increasing effect.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizers, in particular to a weight-loss and efficiency-enhancing water-soluble fertilizer and a preparation method thereof. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed and utilized by crops. It not only contains all the nutrients needed by crops such as nitrogen, phosphorus, and potassium, but also contains humic fertilizers. acid, amino acid, alginic acid, plant growth regulator, etc. Water-soluble fertilizers are easier to realize the integration of water and fertilizer, save water, fertilizer and labor, and the absorption and utilization rate is 2-3 times that of ordinary chemical fertilizers. At present, although the existing water-soluble fertilizers can achieve good water solubility, fast fertilizer efficiency, and high absorpt...

AI Technical Summary

Problems solved by technology

At present, although the existing water-soluble fertilizers can achieve good water solubility, fast fertilizer efficiency, and high absorption rate, the existing water-soluble fertilizers mostly use phosphate as the phosphorus source, and the phosphate ions are easily combined with the added calcium and magnesium ions. Precipitation not only reduces the effectiveness of calcium, magnesium and phosphorus elements, but also easily causes the water-insoluble substances of the product to exceed the standard. Therefore, it is necessary to add complexing agents and chelating agents such as EDTA and citric acid, which increases the cost of fertilizers, and the existing Water-soluble fertilizers do not have the performance of improving and repairing soil. When used in soil with continuous cropping obstacles, even if the amount of fertilizer is increased, the yield and quality of crops cannot be increased and improved accordingly, and weight loss and growth cannot be truly achieved. effective purpose
