Chemical fertilizer special for sunflowers

Abstract

The invention relates to the field of fertilizer, in particular to a chemical fertilizer special for sunflowers. The chemical fertilizer is prepared from, by weight, 20-25 parts of straw, 10-20 parts of saw dust, 10-12 parts of expanded perlite powder, 1-2 parts of nitrification inhibitor DMPP, 0.3-0.5 part of tea saponin, 26-28 parts of potassium nitrate, 21-23 parts of grain dreg fertilizer, 20-22 parts of calcium magnesium phosphate fertilizer, 18-20 parts of urea, 7-9 parts of oligosaccharins, 5-7 parts of photosynthetic bacterium fertilizer, 2-4 parts of bacillus preparation, 3-5 parts of crop straw decomposition preparation, 6-8 parts of humic acid compound fertilizer, 2-5 parts of boron dreg and 1-3 parts of zinc carbonate. The chemical fertilizer is complete in nutrient substance, the stalk of sunflower plants is effectively promoted to be thick and strong, the flower discs are large, grains are full and compact, the grains are high in mature degree, nutrient substance is contained in the formula, soil fertility is increased, environmental pollution is reduced, the yield of the sunflowers is greatly increased, and the quality of the sunflowers is greatly improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special chemical fertilizer for sunflowers. Background technique [0002] The whole body of sunflower is medicine, and its seeds, flower discs, stems and leaves, stem pith, roots and flowers can be used as medicine. Sunflower seeds are sweet and flat, enter the large intestine meridian, have the effect of repelling parasites and stop dysentery, and have a good lipid-lowering effect; the oil in sunflower seeds, especially the linoleic acid part, can inhibit experimental thrombosis. It has the effect of clearing heat and resolving phlegm, cooling blood and hemostasis, and is effective for headache and dizziness. Red eyes, many tears; stem pith can strengthen spleen and dampness and stop belt; root can clear heat and dampness, promote qi and relieve pain; flower can clear heat and detoxify, reduce swelling and relieve pain. [0003] Due to the long growth cycle of sunflowers, especial...

Problems solved by technology

[0003] Due to the long growth cycle of sunflower, especially the seedling stage is not easy to manage, resulting in low yield of sunflower

In addition, the long-term single use of existing sunflower-specific chemical fertilizers by growers will weaken the stress resistance of sunflowers and reduce soil fertility, which is an important factor affecting yield
