Broad-spectrum foliar fertilizer

Abstract

The invention discloses a broad-spectrum foliar fertilizer which is prepared from the following raw materials in parts by weight: 33 to 35 parts of soybean powder, 19 to 21 parts of boric sludge, 1 to 2 parts of carrageenan, 8 to 10 parts of potassium humate, 4 to 5 parts of ammonium phosphate, 0.4 to 0.8 part of glucolactone, 0.3 to 0.5 part of basic sulfonic acid sodium dodecane, 36 to 40 parts of blue-green algae, 16 to 17 parts of corn particles, 2 to 4 parts of anhydrous calcium chloride, a proper amount of calcium carbonate powder, a proper amount of a 5% sulfuric acid solution and a proper amount of water. The broad-spectrum foliar fertilizer disclosed by the invention can meet the demands of various plants for nutritional components, namely, nitrogen, phosphorus and potassium, by use of the potassium humate, the ammonium phosphate and the like according to the demand rule of the plants for nutrition; meanwhile, by the adding of fully composted fermented liquid and chelated trace elements, balanced supplying of the nutrition is realized; furthermore, the foliar fertilizer directly enters a plant body from leaves with relatively large absorption areas, so that the nutrition can be effectively supplemented to various types of agriculture, forestry and animal husbandry plants for a long time.

Description

technical field [0001] The invention relates to the technical field of foliar fertilizers, in particular to a broad-spectrum foliar fertilizer. Background technique [0002] Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts its function through the absorption of leaves. Foliar fertilizer absorbs quickly, has strong effect, saves dosage, and has high efficiency. It can also avoid being fixed by the soil, reduce pollution, and improve fertilizer efficiency. It has great economic value and social benefits. [0003] With the in-depth research on the application of foliar fertilizers, foliar fertilizers have developed from the initial single-type foliar fertilizers to the current multi-type compound foliar fertilizers. However, the development of foliar fertilizers for special geographical environments and special purposes is still relatively small. In addition, the foliar fertilizers currently used in the market mainly ha...

Problems solved by technology

[0005] The patent application with the publication number CN1631850A discloses a biological foliar fertilizer and its preparation method. The solid raw materials and weight ratio of the foliar fertilizer are: urea 50-55%, potassium dihydrogen phosphate 20-25%, chloride Potassium 7-8%, boric acid 0.3-0.5%, ferrous sulfate 0.2-0.4%, copper sulfate 0.1-0.2%, calcium nitrate 0.5-1.5%, magnesium sulfate 0.2-0.4%, zinc sulfate 0.2-0.4%, manganese sulfate 0.2-0.3%, ammonium molybdate 0.05-0.10%, fulvic acid 14-15%, EDTA chelating agent 1-2%, AEO-20 penetrant 0.05-0.10%. Contains metabolites produced by microbial fermentation, but because the nutrients required for plant growth and development in this foliar fertilizer are not comprehensive, and the properties are not stable enough, it is easy to produce precipitation, and it has no effective response to plant disease resistance and special environments. The added value is low, which affects the efficiency of foliar fertilizer use
