Organic fertilizer cultivation method with complete wheat straw returning

Abstract

The invention discloses an organic fertilizing method of returning all wheat straw to field; a complete ditch system is established for autumn sowing wheat seeds, the wheat is sown by adopting strip or band shaped wide-narrow rows, apart from applying fertilizer in sowing season and seedling period, livestock and poultry manure organic fertilizer is applied to wide lines or empty rows of the wheat field in a plurality of periods; rice straw is turned and buried by combining intertill of the wide lines and the empty rows from winter to shooting stage; wheat stubble is kept 25-30cm when the wheat is mechanically harvested, then the rest wheat straw is buried in the wheat field ditches; the wheat field is irrigated, and paddy rice is planted in the empty rows among the wheat stubble, thus forming a band-shaped layout; only a chemical fertilizer is applied as a base fertilizer used in paddy rice plantation and as a tillering fertilizer, and the other base fertilizer adopts livestock and poultry manure organic fertilizer; when the water supply of the paddy field is cut off for field drainage, the wheat straw buried in the field ditch is taken out and distributed in the wide lines or empty rows of the paddy field, 1-4 days before finishing field drainage and rewatering, the livestock and poultry manure organic fertilizer is applied as a panicle fertilizer in the wide lines or empty rows of the paddy field. The organic fertilizing method of returning all wheat straw to field has the advantages of simple operation, and can effectively realize resource recycling of straw and livestock and poultry manure.

Description

Technical field: [0001] The invention relates to a method for organically fertilizing the whole wheat straw by returning it to the field. Background technique: [0002] In the existing wheat and rice farming mode, chemical fertilizers are basically used as the main fertilizer, and straws are generally treated by methods such as incineration, which is wasteful and pollutes the environment. Summary of the invention: [0003] The purpose of the present invention is to provide an organic fertilization method for fully returning wheat straw to the field, which is simple in operation and can effectively realize the recycling utilization of straw and livestock manure. [0004] The technical solution of the present invention is: [0005] An organic fertilization method for fully returning wheat straw to the field is characterized in that it includes the following steps in sequence: [0006] (1) In the wheat and rice double-cropping rice field, the autumn sowing wheat is based on the bor...
