Paddy rice mechanized production promoting and straw total returning integrated method

Abstract

The invention belongs to the technical field of crop planting, and discloses a paddy rice mechanized production promoting and straw total returning integrated method. The paddy rice mechanized production promoting and straw total returning integrated method has the advantages that new varieties suitable for mechanical rice seedling transplanting are selected, pesticides, fertilizers and water arescientifically planned and managed, and accordingly vigorous seedlings can be bred; stalk basal internodes can be shortened under the precondition that the biomass is not reduced, accordingly, ineffective tillering can be reduced, the plant heights and the lengths of flag leaves can be controlled, and the lodging resistance can be enhanced; harvesting machines are provided with straw smashing equipment, total straw can be smashed and sprayed during mechanical harvesting, tractor-plowing, soaking and rotting are carried out, drainage and mechanical rice seedling transplanting are carried out after two days, accordingly, mechanical harvesting, tractor-plowing, mechanical rice seedling transplanting and matched cultivation technologies can be fused with one another, total straw smashing, rotting and returning can be promoted, the soil fertility can be recovered, burning is completely eradicated, the usage of chemical fertilizers and pesticides can be reduced, and sustainable and green paddy rice production can be promoted; the paddy rice mechanized production promoting and straw total returning integrated method is practical in the aspect of production, is feasible in the aspect of popularization and has merits in the aspect of technologies; agricultural yield increase and income increase of farmers can be promoted by the paddy rice mechanized production promoting and straw totalreturning integrated method, rural environments can be improved, and the paddy rice mechanized production promoting and straw total returning integrated method has obvious economic and social benefitsand a broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to an integrated method for promoting the full amount of straw returning to the field through mechanized rice production. Background technique [0002] For a long time, in rice production, it is very common for farmers to use a large amount of chemical fertilizers, which not only increases the cost of planting, but also causes the compaction of farmland and the eutrophication of non-point water bodies, resulting in many environmental pollution problems. By applying excessive chemical fertilizers to rice, the rice has excess nutrition, and the output of rice straw is also increasing. At present, during the period of double-cropping rice in southern my country, in order to compete for the farming season, farmers basically return the straw to the field by burning, which not only causes air pollution, but also destroys the soil structure, resulting in the decline of fa...

Problems solved by technology

In addition, there are still problems to be overcome such as uneven seedling emergence, high rate of missing seedlings, and high seeding rate leading to too large a population. The development of standard seedling raising technologies such as standard plate, floppy plate seedling raising, double-film seedling raising, and stacking plate dark seedling emergence has greatly promoted The development of mechanized rice transplanting

[0005] To sum up, the problems existing in the mechanized production technology of double cropping rice, Rice stalks are returned to the field in the form of incineration, causing environmental pollution. There are few varieties suitable for machine-transplanting. Poor seedling raising technology leads to poor quality of machine-transplanted seedlings. The three most important links of machine-cultivation, machine-transplanting, and machine-harvesting are not equipped with mechanized equipment. The derived rice stalks cannot be fully returned to the field, and the effect of machine transplanting is not ideal, so it is difficult to promote and implement on a large scale
