Embodiment 2

[0024] A paddy field wheat straw covering no-tillage cultivation technique, its concrete steps are as follows:

[0025] (1) Paddy field selection: No-tillage cultivation of paddy field and wheat requires the selection of fields with convenient drainage and certain sandiness. Fields with too much viscosity will make the paddy field over-hardened, which is not conducive to deep root penetration and field plowing in the coming year. Before harvesting rice, it is necessary to do a good job of drainage and put it in the field. When harvesting, it is necessary to cut the rice evenly.

[0026] (2) Straw preparation: After the rice is harvested, dry the straw to 50% and pile it up for later use. If the straw is too dry, it is not conducive to composting and rotting, and if the seeds are covered with dry straw, it is not conducive to moisture conservation and emergence, and will bring difficulties to wheat harvesting and plowing; if the straw is too wet, the rot will be too heavy, maki...

Abstract

The invention discloses a paddy field wheat straw coverage no-tillage cultivation technology. The technology comprises the steps of firstly, selecting a paddy field; secondly, preparing straw; thirdly, arranging the field; fourthly, sowing seeds; fifthly, covering the seeds with the straw; sixthly, managing the field; seventhly, preventing and controlling diseases and pests. The technology has the advantages that the ecological environment is protected, water corrosion and wind corrosion of soil are reduced, labor intensity is lowered, expenses are saved, soil nutritional structure is improved, soil water and organic matter loss is prevented, fertility is improved, weeds, diseases and pests are effectively controlled, and the yield of crops is increased.

Description

technical field [0001] The invention belongs to the field of crop cultivation, and in particular relates to a no-tillage cultivation technique of paddy fields covered with wheat and straw. Background technique [0002] In the prior art, after the rice in the paddy field is harvested, wheat seeds are sown after the rice stubble is plowed, and the straw after harvesting is mostly treated by direct burning, and plant ash is sprinkled in the field as base fertilizer. The disadvantages of this technology are: (1) Burning rice straw causes a large amount of harmful gases such as carbon dioxide to fill the space, which seriously affects air quality and also affects traffic safety; (2) Tilling the soil is labor-intensive, time-consuming and expensive; (3) Tilling the soil Weeds are easy to grow and difficult to control; (4) plowing destroys soil nutrient structure, water and soil organic matter are easy to lose; (5) yield is low. Contents of the invention [0003] In view of the ...
