The invention discloses a method for returning a full amount of decomposed straw to the field by using a decomposing agent, including the steps of removing diseased plants, preliminary crushing, secondary crushing, applying decomposing agent, applying nitrogen fertilizer, deep plowing, raking and winter irrigation. In the invention, the straw decomposing agent is used to promote the rapid decomposing of the straw in the low temperature environment in the north. The straw and organic waste are rapidly decomposed and decomposed to form biological fertilizer. The rapid decomposing of straw can release phosphorus, potassium and other elements in the straw, and produce a large number of beneficial microorganisms, which can increase soil organic matter, improve soil fertility, reduce the use of inorganic fertilizers, and reduce agricultural environmental pollution. Applying an appropriate amount of nitrogen fertilizer to the straw can speed up the rate of straw decomposing without reducing the nitrogen content in the soil; irrigation in winter can ensure that the soil in northern winter has a certain soil moisture and provide necessary humidity conditions for straw decomposing. |
