The invention belongs to field of agricultural cultivation techniques, and relates to a cultivation method for crops, in particular to a furrow, film, ridge and straw combined type mulching cultivation method for the crops. The method includes the steps of farmland selection, soil preparation, ditching, ridging, basal dressing, intercropping of plants among ridge surfaces according to specification layout, ridge surface straw mulching and furrow body film mulching after crop seeding, top dressing in the seedling stage and the fast-growing stage of the plants, and recovery of mulching film after harvest. The method overcomes shortcomings of straw mulching and film mulching, achieves sustainable production of the crops, reduces waste of agricultural resources and environmental pollution, improves rainfall infiltration, restrains soil evaporation, improves hydrothermal conditions of soil, improves the nutrient status of the plants due to nutrients provided by straw, protects cultivated land, prevents loss of water and fertilizer on the surface of the soil, improves yields of the crops, changes an existing mulching cultivation production method for the crops, and achieves the purpose of protective mulching cultivation.
Description
technical field [0001] The invention relates to a cultivation method for crops, in particular to a composite covering cultivation method of crops with furrows, membranes, ridges and straws, and belongs to the technical field of agricultural cultivation. Background technique [0002] Field mulching is a crop cultivation technique with a long history. Nowadays, the main covering materials widely used in agricultural production in various countries in the world are various types of plastic film. The wide application of plastic film has greatly promoted the development of farmland covering cultivation and the improvement of crop yield, but due to its anti-decomposition characteristics, the residues in The mulch in the soil or into the surrounding environment is difficult to degrade naturally, causing the so-called "white pollution". Agricultural wastes such as straw and livestock manure are excellent mulches with a long history of application. They not only promote crop growth ...
