Production method and equipment of pig manure fertilizer influencing yield of single-cropping late rice

Abstract

The invention discloses a production method and equipment of a pig manure fertilizer influencing the yield of single-cropping late rice. The pig manure fertilizer is prepared from the following raw materials in parts by weight: 50 to 100 parts of biogas slurry, 0 to 0.196 part of nitrogen fertilizer, 0 to 0.275 part of phosphate fertilizer and 0 to 0.173 part of potash fertilizer. The biogas slurry formed by fermenting pig manure is used as a main raw material, a nitrogen fertilizer, a phosphate fertilizer and a potash fertilizer are added as auxiliary materials, and the biogas slurry and the phosphate fertilizer are used as base fertilizers to be applied at a time through sedimentation fermentation of the biogas slurry; the chemical potash fertilizer comprises 50% of base fertilizer and 50% of jointing fertilizer which are applied twice; 30% of the nitrogen fertilizer as the base fertilizer, 50% of the additional fertilizer in the seedling establishment period and 20% of the jointing fertilizer are applied for three times, nutrient elements contained in the biogas slurry are very beneficial to rice production, the application ratio of the biogas slurry to the inorganic nitrogen-phosphorus-potassium fertilizer is determined, the use amount of chemical fertilizers in grain production is reduced, the agricultural pollution pressure is relieved, the grain production capacity is guaranteed, and the agricultural benefits are improved safely; the production cost is reduced, and green agriculture development is promoted.

Description

technical field [0001] The invention relates to the technical field of farmland fertilizers, in particular to a method and equipment for producing pig manure fertilizers that affect the output of single-season late rice. Background technique [0002] Food security is related to the national economy and people's livelihood. In order to ensure food production capacity and safety, improve agricultural efficiency, reduce production costs, and promote the development of green agriculture; in order to improve soil physical properties and achieve sustainable agricultural green development, in recent years we have used biogas slurry and other agricultural organic matter in food production. , it can not only reduce the pressure of agricultural pollution, but also reduce the amount of chemical fertilizers used in food production. However, there is currently a lack of a reasonable method of using biogas slurry to apply fertilizers. At the same time, how to further reduce the addition o...

In order to ensure food production capacity and safety, improve agricultural efficiency, reduce production costs, and promote the development of green agriculture; in order to improve soil physical properties and achieve sustainable agricultural green development, in recent years we have used biogas slurry and other agricultural organic matter in food production. , it can not only reduce the pressure of agricultural pollution, but also reduce the amount of chemical fertilizers used in food production. However, there is currently a lack of a reasonable method of using biogas slurry to apply fertilizers. At the same time, how to further reduce the addition of external fertilizers is also a way to protect An urgent need to protect resources and protect the environment;

[0003] Simultaneously, when the mixing device in the current pig manure biogas digester produces pig manure fertilizer, its salvage rod rotates, and when salvaging raw materials in the biogas digester, it often occurs that long strips of raw materials (such as straw) are entangled in the salvage rod. The head part has more winding times, which seriously affects the fishing effect of the fishing rod
