Organic fertilizer for improving saline-alkali tolerant stress resistance of paddy rice

Abstract

The invention discloses an organic fertilizer for improving the saline-alkali tolerant stress resistance of paddy rice. The organic fertilizer is prepared from the following raw materials: bean dregs,peanut residues, soybean residues, biogas digester precipitation dregs, gypsum, a nitrification inhibitor DMPP (Dimethyl-phenyl-piperazinium), a willow leaf, a pine needle leaf, a poplar leaf, a silicon fertilizer, silicate, calcium chloride, ferrous sulfate, talcum powder, microorganism strains, calcium humate, sodium carbonate, slaked lime, zinc sulfate, rice washing water and outdated beer. Apreparation method is simple; the prepared organic fertilizer for planting the paddy rice has a high utilization rate; the investment of conventional fertilizer is reduced and nitrogen activity is improved; original nutrients in soil can be activated and sufficiently absorbed and utilized by crops, so that the yield of the crops is increased, the stress resistance of the crops is improved and thesoil can be effectively improved; the organic fertilizer is strong in adaptability, especially suitable for saline-alkali hardened soil and good in compatibility, and various types of fertilizers canbe added into the organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of modern agricultural planting, in particular to an organic fertilizer for improving the salt-alkali tolerance and stress resistance of rice. Background technique [0002] Organic fertilizer refers to a type of fertilizer that contains organic substances and can not only provide a variety of inorganic and organic nutrients for crops, but also fertilize and improve the soil. Most of them are collected by farmers on the spot and made by themselves. [0003] Organic fertilizers are part of the recycling and reuse of nutrients in agriculture, so the amount of organic fertilizers has increased as fertilizer applications have increased and crop harvests have increased. Although the proportion of nutrients input by organic fertilizers has decreased significantly due to the large increase in chemical fertilizer input in recent years, it still accounts for 36.7% of the total input of nutrients.
