High-yield environment-friendly method for applying fertilizer to red and yellow soil land

Abstract

The invention discloses a high-yield environment-friendly method for applying a fertilizer to red and yellow soil land, which comprises the following steps: A. composting: carrying out heap fermentation on livestock and poultry manure collected from cultivation farms, killing pathogenic bacteria and parasites in the livestock and poultry manure, and measuring the dry matter content of the fermented livestock and poultry manure; B. land preparation: tilling and leveling the red and yellow soil by using a minitype tilling machine; C. fertilizer application: applying the fermented livestock and poultry manure to the tilled and leveled red and yellow soil land in a way of 2.3-4.5 tons of dry matters per hectare, and turning over the soil, so that the manure is mixed into the upper soil layer; D. sowing: directly sowing seeds or transplanting the needed crops, and watering; E. intertillage and weeding: intertilling in the crop growing season, and weeding in combination with intertillage; F. disease and pest control; and G. harvesting: harvesting when the crops become ripe. The method has the advantage of low cost, is easy in realization and simple and convenient in operation, is widely suitable for applying livestock and poultry manure to medium / low-yield red and yellow soil land, improves the soil quality and increases the soil nutrient content.

Description

technical field [0001] The invention relates to the technical field of farmland fertilization, and more specifically relates to a method for applying livestock and poultry manure organic fertilizers to red-yellow soil cultivated land, so as to improve the productivity of low-yield red-yellow soil land, achieve high-quality and high-yield cultivation of crops, and protect the agricultural environment. Background technique [0002] Red-yellow soil is the main type of soil widely distributed in subtropical regions of China, with a total area of ​​2.18 million square kilometers, accounting for 22.7% of the country's total land area, and the area of ​​red-yellow soil arable land accounting for 28% of the country's total arable land area. However, due to the low soil organic matter content and serious shortage of nitrogen, phosphorus, potassium and other nutrients in the red-yellow soil cultivated land, the soil structure is poor and the crop yield is very low. The application of c...

Problems solved by technology

A large amount of livestock and poultry manure produced by intensive farming has caused serious environmental pollution to water sources, which has led to the phenomenon of "no breeding pens" planned by government departments in important water source areas in some cities. The key problem is that the utilization of livestock and poultry manure has not been solved. solving issues
