Entire-process-mechanized medium-low-stubble cultivation method for ratooning rice

Abstract

The invention belongs to the technical field of crop cultivation and particularly relates to an entire-process-mechanized medium-low-stubble cultivation method for ratooning rice. The method comprisesthe steps: A. variety selection; B. rice seedling raising bed soil preparation; C. rice seedling bed preparation; D. timely early-sowing; E. sowing and machine-transplant rice seedling raising; F. land preparation and furrowing; G. rational close planting; H. fertilizer application; I. moisture management; J. 90%-yellow reaping and reasonable stubble reserving; K. disease and insect pest control;and L. ratooning rice reaping. Through applying the method to ratooning rice production, the ripening stage difference between an entire-process-mechanized ratooning rice rolling region and a non-rolling-region is shortened to about 10 days, the germination of axillary buds is promoted, the yield and rice quality of the ratooning rice are improved, the labor intensity and labor input are greatlylowered, the cost reducing and synergistic effects are obvious, and the production increase and income increase of farmers are promoted.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a whole-process mechanized method for cultivating ratooned rice with medium and low stakes. technical background [0002] Raisoning rice is commonly known as "Bao Sun Valley" or "Yang Sun Valley" and so on. It uses the dormant buds that survived on the rice pile after harvesting, and adopts certain cultivation and management measures to make them germinate into regeneration tillers, and then heading to maturity and harvesting for another season. A resource-saving rice farming method, which has the characteristics of saving planting, labor, time, water, fertilizer, medicine, seedling fields, increasing production, increasing income, and high-quality rice. At present, the cost of growing grain continues to rise, Under the dual pressure of "double change to single" and the increasing abandoned area, ratooning rice has become a problem in southern my country with m...

AI Technical Summary

Problems solved by technology

The whole mechanized ratooning rice can be divided into: the whole mechanized high-stake ratooning rice (the height of the pile is ≥ 40cm, after harvesting, keep 2 or less nodes to regenerate axillary buds) and the whole-process mechanized medium and low-stake ratooning rice. For ratooning rice (stake height ≤ 30cm, regenerate axillary buds at or below 4 nodes after machine harvesting), Nie Lixiao et al. (2013) proposed a two-harvest full-process mechanized rice cultivation method suitable for pile height ≥ 40cm. However, the cultivation methods of fully mechanized ratooning rice with different heights of piles are quite different, and this method is not suitable for whole-process mechanized ratooning rice with low piles. In addition, Liu Zhengzhong et al. (2013) proposed that the height of piles of whole-process mechanized Raising 10cm, the maturity period of the regenerated crop rice in the rolled area and the non-rolled area is extended by 4-6 days, and the maturity period of the regenerated crop rice in the rolled area and the non-rolled area with a pile height ≥ 35cm can reach about 20 days, which affects the The output and rice quality of regenerated crop rice, therefore, the object of the present invention is to explore and establish a kind of middle and low stake ratooned rice cultivation technology based on the whole mechanized operation, in order to shorten the rolling area and non-rolling area of ​​the whole mechanized regenerated crop rice Differences in maturity stage, improving the production level of ratooned rice with low and medium piles in the whole process of mechanization, and providing technical support for farmers to increase production and income, and promote the large-scale promotion and application of this technical model
