Special humic acid rare-earth multi-element coated fertilizer for strawberries and preparation method of special humic acid rare-earth multi-element coated fertilizer

Abstract

The invention discloses a special humic acid rare-earth multi-element coated fertilizer for strawberries. The special humic acid rare-earth multi-element coated fertilizer is characterized by being prepared from the following raw materials in parts by weight: 25-27 parts of rape seed cake, 34-38 parts of wood scrap, 13-16 parts of fulvic acid, 16-19 parts of humic acid, 5-7 parts of attapulgite, 30-35 parts of banana peel, 13-17 parts of potassium metaphosphate, 8-12 parts of calcium magnesium phosphate, 37-39 parts of peanut bran, 18-20 parts of ammonium polyphosphate, 2-3 parts of pentaerythritol, 1-2 parts of zinc borate, 4-6 parts of rare-earth multi-element fertilizer, 5-8 parts of an EM bacterium agent, 13-18 parts of urea, 8-10 parts of soil conditioner and an appropriate amount of water. The fulvic acid and the humic acid, which are added into the fertilizer, have the functions of promoting crop growth, improving cold resistance, strengthening a root system and improving the granular structure of soil; moreover, the fertilizer is chelated with zinc and the rare-earth multi-element fertilizer, so that the element absorption of crops is promoted; the crops have the functions of water retention and drought resistance by virtue of the added soil conditioner; the variety quality can be improved by using the fertilizer, the good yield-increasing effect is achieved, and the soil structure and the fertilizer efficiency are improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a rare-earth humic acid multi-component coated fertilizer dedicated to strawberries and a preparation method thereof. Background technique [0002] Coated fertilizers are also called coated fertilizers and film fertilizers. Fertilizers made of quick-acting fertilizer granules wrapped with semi-permeable or impermeable film substances. The purpose of the coating is to slowly release the quick-acting nutrients in the coated fertilizer after it is applied to the soil, so as to prolong the fertilizer effect. The release rate depends on the type of coating, thickness, particle size, fertilizer solubility, soil temperature, soil water content, and soil microbial activity. Crops, and high temperature, rainy areas or irrigated areas where nutrients are prone to leaching, especially on light sandy soils. At present, the coating materials are many and miscellaneous, and they are not targeted....

AI Technical Summary

Problems solved by technology

At present, the coating materials are many and miscellaneous, and they are not targeted. Therefore, it is necessary to prepare a nutritionally balanced and reasonable fertilizer according to the growth characteristics of the crops, and then select a suitable coating material according to the function and characteristics of the fertilizer, so that the prepared fertilizer will be able to exert its full potential. Optimum performance and environmental protection. Studies have shown that whether it is a single rare earth or a mixture of rare earths, it has a very effective effect similar to trace element fertilizers. The appropriate concentration of rare earths has effects on seed germination, photosynthesis, and dry matter accumulation. Stimulation, which can increase crop yields, accelerate ripening and improve the quality of some crops
