Problems solved by technology

At present, biostimulants only focus on improving the utilization rate of effective nutrients, but do not pay attention to the growth of plant roots. Plant nutrients are mainly absorbed by roots. The addition of biostimulants can improve the utilization rate of effective nutrients, but the development of plant roots is very weak. Nutrients produced by Fuyu cannot be fully absorbed within a certain period of time. Nutrients may be lost due to capillary action of groundwater or leaching of rainwater.
At present, there is a lack of water-soluble fertilizers containing biostimulant substances on the market that focus on the growth of the plant's own root system on the basis of improving the effective nutrient utilization rate, so as to maximize the increase in production.

Abstract

The invention discloses a water-soluble fertilizer containing a biostimulant substance and a preparation method thereof. The water-soluble fertilizer is prepared from, by weight, 4-6 parts of alginicacid, 8-12 parts of humic acid, 3-5 parts of rooting agent, 2-3 parts of ammonium bicarbonate, 15-25 parts of urea, 10-20 parts of potassium carbonate, 10-15 parts of monopotassium phosphate, 5-10 parts of ammonium dihydrogen phosphate, 6-10 parts of calcium superphosphate, 1-3 parts of dispersing agent, 6-8 parts of zinc sulfate and 2-4 parts of manganese sulfate. The water-soluble fertilizer containing the biostimulant substance is solid, is convenient to store and transport, reasonable in composition and comprehensive and balanced in nutrition, the effective nutrient utilization rate can beimproved, crop root system growth can be also promoted, accordingly the purpose of increasing the yield and incomes is achieved, and the water-soluble fertilizer is suitable for various irrigation facilities. The preparation method is simple, controllable and suitable for large-scale industrial production and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizers, and in particular relates to a water-soluble fertilizer containing biostimulant substances and a preparation method thereof. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops. It also has a relatively high absorption and utilization rate, realizes the integration of water and fertilizer, and saves water, fertilizer and labor. It is a new type of fertilizer that has emerged in recent years. Generally speaking, water-soluble fertilizers can contain all the nutrients needed for crop growth, such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, etc. Therefore, in high-yield, high-quality, high-efficiency, healthy and environmentally friendly agriculture, the vigorous development of water-soluble fertilizers is essenti...
