Description

A kind of strawberry cultivating sulfur fertilizer and preparation method thereof
Technical field
The present invention relates to fertilizer and its processing technique field, in particular to a kind of strawberry cultivating sulfur fertilizer and its preparation side Method.
Background technique
For strawberry because of economic value height, cultivated area is more and more, in the fertilising of strawberry, applies certain seed manure to fertilize or singly partially Material, soil is after transplanting strawberry many years, it is easy to hardened, salt dampization, soil-borne disease phenomenon occurs, seriously affect the life of strawberry Long and quality, soil fertilizer water holding capacity, the conversion of matter and energy, microbial ecosystem etc..
China Patent No. 201710295327.X discloses a kind of chromium-rich strawberry compound fertilizer of selenium-rich and application method, by including The raw material of following parts by weight is prepared：Compound fertilizer 400-600 parts, 100-200 parts of ammonium sulfate, 250-300 parts of wattenshlick soil, yellow corruption Sour boron 100-150 parts, 20-50 parts of humic acid, 5-10 parts of composite trace element, 40-60 parts of peanut press pulp, 1-2 parts of sodium selenate, trichlorine Change chromium 0.01-0.05 parts.Its application method of the compound fertilizer is：Selection soil layer is deep, does not leak the soil of fertilizer, with peanut shell powder and Folium isatidis powder is carrier, Base-appling once, kind, fertilizer isolation.The present invention has yield of strawberry height, plant disease resistance strong, suitable big The advantages of area discharges, and the strawberry fruit tied is larger and again, and good quality, the chromium-rich strawberry of selenium-rich contains human body and animal is necessary Selenium element and trivalent chromium, nutritive value is high, good for health；China Patent No. 201510435661.1, which discloses one kind, to be had The inorganic strawberry special blending fertilizer formula of machine, the formula according to balance fertilizing " law of cask " principle, according to strawberry regulation of fertilizer requirement Science is formulated, and 1000 kilograms of organic-inorganic strawberry mixing fertilizer speciallies of every preparation need 1.8~2.2 parts of urea, monoammonium phosphate 1.8~2.2 parts, 1.8~2.2 parts of potassium chloride, 3.3~3.7 parts of organic fertilizer, 0.3~0.7 part of calcium magnesium phosphate, stirring blending, are made into N P and K three elements 17: 9: 12, total nutrient 38%, middle microelement 6.5%；Organic matter 7%, amino acid 3.5%, humic acid 3.5% organic-inorganic strawberry mixing fertilizer specially；Due to the formula include big (nitrogen, phosphorus, potassium), in (calcium, magnesium, sulphur), micro- (copper, iron, manganese, boron, zinc, molybdenum, chlorine) all nutrients；Organic matter, amino acid, humic acid have entirely, have price low, and fertilizer efficiency is high, needle The advantages that strong to property；China Patent No. 201510188392.3 discloses a kind of Special fertilizer for strawberries, including it is following by weight Component：Urea：25.4-30.2 parts；Ammonium hydrogen carbonate：20.1-23.3 parts；Calcium superphosphate：11.4-13.6 parts；Potassium chloride： 20.1-23.9 parts；Calcium nitrate：8.5-11.4 part；Magnesium sulfate：0.8-1.0 parts；Ethylenediaminetetraacetic acid iron：0.6-0.8 parts；Zinc oxide： 0.38-0.57 parts；Manganese sulfate：0.3-0.4 parts；Copper sulphate：0.15-0.2 parts；Boric acid：0.1-0.18 parts；Ammonium molybdate：0.05- 0.1 part.Compared with common fertilizer, the yield of strawberry produced using the Special fertilizer for strawberries in the present invention is higher, mouthfeel more preferably, Nutrition is richer.
Document above all passes through optimization fertilizer formula and solves the problems, such as nutrition or disease, but fails to comprehensively consider plant absorption rule Situations such as rule, disease-resistant performance, soil, microorganism.Those skilled in the art know that sulphur is nutrient necessary to plant growth One of, 90% sulphur is present in sulfur-containing amino acid in plant, and amino acid is the important indicator for evaluating protein quality, It is the important substance of intracellular certain compound synthesis, sulphur can also improve the utilization rate of the required nutrient of other crops, especially nitrogen And phosphorus, to improve crop yield, but effective sulphur is less in soil, crops a lack of sulfur phenomenon, which has become one and cannot be neglected, is asked Topic, for this purpose, the literature aims to solve the problem that strawberry cultivating problem, providing has targetedly sulfur fertilizer, reduction conventional composite fertilizer usage amount, Increase organic matter, improve acidified soil pH value, supplement beneficial element, increases the compound with improvement soil, increase beneficial to micro- Biomass improves yield of strawberry.
Summary of the invention
The present invention is in order to solve the above technical problems, provide a kind of strawberry cultivating sulfur fertilizer and preparation method thereof.
It is realized particular by following technical scheme：
