Special compound mixing fertilizer for winter wheat

Abstract

The invention discloses a special compound mixing fertilizer for winter wheat. The special compound mixing fertilizer is prepared from the following raw materials in parts by weight: 12 to 14 parts of biochemical fulvic acid, 10 to 12 parts of flue-cured tobacco powder, 38 to 40 parts of furfural residue, 20 to 25 parts of peat soil, 2 to 4 parts of sodium tartrate, 4 to 6 parts of calcium ammonium nitrate, 6 to 8 parts of potassium humate, 2 to 3 parts of ground phosphate rock, 26 to 28 parts of waste newspaper, 1 to 2 parts of potassium persulfate, 34 to 36 parts of yellow mealworm dung, 0.5 to 0.8 part of ferric chloride hexahydrate, 0.4 to 0.5 part of ammonium iron(II) sulfate, a proper amount of 25% phosphate solution, and a proper amount of water. The special compound mixing fertilizer has the advantages that according to the environment characteristics of planting of winter wheat, a large amount of humic acid organic ingredients is added, the deeper color is favorable for the soil to absorb heat energy in winter, the daytime and night temperature difference of the soil is decreased, and the mineral nutritional elements in the fertilizer are balanced by the flue-cured tobacco powder, peat soil and the like; after absorbing, the low-temperature resistance of winter wheat is improved, and the stable production and high yield of the winter wheat are realized.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special compound fertilizer for winter wheat. Background technique [0002] my country is a large agricultural country, and the amount of fertilizer used is extremely high. However, the current fertilizer and its corresponding fertilization technology have kept the fertilizer utilization rate in my country at a low level for a long time, seriously affecting the enthusiasm of farmers for planting, and causing serious pollution to the environment. , It is not conducive to the construction of an efficient and high-yielding modern industrial technology system for sustainable development in my country. Based on national food safety requirements and high-yield goals, the use of chemical fertilizers has continued to increase. Some farmers' blind fertilization has caused soil, water quality, and crop pollution, decreased fertilizer efficiency, and increased food costs. Therefore, i...
