Embodiment Construction

[0029] The present invention is described in further detail below.

[0030] The steps of the technical solution of the present invention are: creation of suitable soil moisture before harvesting of rice → application of base fertilizer → no-tillage sowing of wheat → harvesting of rice combine harvester, chopping and spreading of straw → artificially assisted straw scattering → mechanical ditching and soil throwing to suppress straw → irrigation Shen solid. Specifically, the following detailed steps are included:

[0031] At first for better realizing the object of the present invention, select suitable rice variety.

[0032] The wheat sowing method commonly used in the prior art is that after the rice is harvested, it can only be sown when the soil moisture in the paddy field reaches a suitable level (generally, it needs to be dried for 3-5 days). By using the present invention, no-tillage wheat can be carried out 0-3 days before the rice is harvested. Sowing is about 5 day...

Abstract

The invention provides a no-tillage seeding straw mulching method for wheat bred under rice stubbles. The no-tillage seeding straw mulching method for wheat bred under rice stubbles particularly includes the steps of creation of proper moisture before harvesting of rice, application of base fertilizer, wheat no-tillage sowing, harvesting through a rice combine harvester and cutting and throwing of rice straw, labor-aided uniform dispersing of straw, mechanical ditching, soil throwing and straw compacting, and irrigation and soil sedimentation. The no-tillage seeding straw mulching method for wheat bred under rice stubbles overcomes the technical bottleneck problems that under a wheat-rice double cropping planting system in the prior art, rice straw mulching is difficult, the wheat sowing quality is poor, and the yield is low, is a continuous and advanced cultivation method which can fertilize the soil, save the cost, increase the yield, improve the effect and protect the ecologic environment, and realizes the purposes of no-tillage seeding for wheat bred under rice stubbles and rice straw mulching.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to no-tillage sowing of rice stubble and wheat and rice straw returning to the field. Background technique [0002] Crop straw is an important biological resource. Straw is rich in nutrients such as nitrogen, phosphorus, potassium and organic matter. It is an unused agricultural product resource in China. There are nearly 600 million tons of straw in my country every year, but less than 20 million tons are used, and about 97% of the straw is burned, piled up and abandoned [1] , causing waste of resources and polluting the environment, has become a serious economic and social problem, and has become a hot and difficult issue of government concern, social concern, and public opinion concern. Therefore, how to do a good job of returning crop straw to the field has become an urgent agricultural problem to be solved. . [0003] Straw returning can fertilize the soil, improve the phys...
