Water-fertilizer conditioning method for rice straw mulching and returning in wheat season

Abstract

The invention discloses a water-fertilizer conditioning method for rice straw mulching and returning in wheat season, which belongs to the field of water-fertilizer conditioning of crops, in particular to a water-fertilizer conditioning technology under the rice straw mulching and returning way in the small spring wheat season of Chengdu Plain. In the Chengdu Plain, rice straws harvested in the previous season are used for total mulching and returning, thereby carrying out quantitative water regulation and soil fertilizer conditioning during the whole growth period of wheat; the method combines the straw total returning with the water-fertilizer conditioning technology, thereby avoiding the possible negative effects to the soil caused by simple returning during the straw decomposition process, integrating the cultivation technology which is matched with straw returning, optimizing a system of fast conversion and utilization of straws and the crop stable and high yield technology and designing the reasonable water-fertilizer conditioning scheme; furthermore, the tillage measures can not only improve the yield of the crops, save the labor force and improve the economic benefits, but also retain water and fertilizer, improve the soil structure, protect the environment and promote the sustainable development of agriculture in the region.

Description

technical field [0001] The invention relates to a method for returning crop stalks to the field, in particular to a water and fertilizer control method in the mode of mulching and returning crop stalks in the small spring wheat season in the Chengdu Plain. Background technique [0002] Straw accounts for about 50% of the crop biological yield, and is an extremely abundant and most directly usable renewable organic resource. The incineration of a large amount of remaining straw not only causes air pollution and has a serious impact on the living environment, but also causes soil fertility to decline year by year, and the agricultural ecological balance is so bad that it is destroyed. Straw returning to the field can effectively increase the content of soil organic matter, supplement its various nutrient elements, and make its nutrient structure more reasonable, thereby improving soil physical and chemical properties and fertilizing soil fertility, especially to alleviate the ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the existing methods of straw returning to the field during the wheat season, the lack of norms for fertilization and irrigation of straw returning to the field, and other practical problems, and to provide an efficient, safe, and highly operable specific process-based wheat The water and fertilizer control mode of straw returning to the field in the season focuses on the quantitative control of water and fertilizer in the no-tillage mulching method of straw returning to the field, which is more conducive to playing a role in actual agricultural applications and solving the specific operation problems of straw returning to the field in terms of water and fertilizer regulation
