Problems solved by technology

The problems existing in the disclosed prior art include: (1) The fertilizers used are general quick-acting chemical fertilizers, and the seasonal utilization rate of fertilizer nutrients is very low. The utilization rate of nitrogen fertilizer is only 30-35%, and the utilization rate of phosphorus fertilizer is about 10-20%. %, the utilization rate of potassium fertilizer is 35-50%, which causes serious environmental pollution at the same time as huge economic loss; (2) While focusing on quick-acting chemical fertilizers, the application of organic fertilizers and micro-fertilizers is ignored; crops, but fertilizer planning is not carried out according to the purpose of production or processing; (4) Fertilizer is divided into base fertilizer and topdressing fertilizer, which increases the cost of fertilization

Abstract

The invention discloses a common fertilizer special for sesbania in medium and low-yield fields in a Huang-Huai-Hai region and belongs to the field of fertilizer preparation. An organic matrix, an inorganic matrix, a nitrogen fertilizer, a phosphate fertilizer, a potassic fertilizer and a trace element chelating agent serve as basic raw materials. The preparation method comprises the following steps: spraying, granulating activating agents and preparing the fertilizer through disc granulation, wherein the nitrogen fertilizer, the phosphate fertilizer and the potassic fertilizer are mixed according to a mass ratio 5-9:14-20:0-2 of N:P2O5:K2O. The common fertilizer special for sesbania serving as a base fertilizer is applied at a time, is simple in production process, low in cost, environment-friendly, high in utilization rate and obvious in yield-increasing effect and is suitable for needs of common fertilizer special for sesbania in medium and low-yield fields in the Huang-Huai-Hai region and feed or particle production.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a special fertilizer for ordinary green turnip suitable for medium and low-yield fields in the Huang-Huai-Hai region, and a preparation and application method thereof. Background technique [0002] Common Sesbania (Sesbania cannabina Pers.) is an annual herbaceous leguminous plant with strong stress resistance and strong soil adaptability. It can grow in acidic, alkaline, saline-alkali soil, dry land, and waterlogged land. Its root system is well developed , mostly distributed in the 20-40cm soil layer, with many and large root nodules, strong nitrogen fixation ability, and can form a large number of stem nodules, which makes Tianjing an excellent summer green manure, and can be used as soil restoration and Transformed pioneer plants. In addition, common sage is also a good feed for poultry, livestock, and fish, and its seeds can also be used to produce sage gum, which is us...
