AI Technical Summary

Technical Problem

The track width of traditional rice harvesters causes crushing damage to dormant buds of ratooning rice. Existing agronomic methods are insufficient to increase the yield of ratooning rice, and weeding devices are not suitable for ratooning rice planting patterns, resulting in reduced yields.

Method used

By adopting a parallel planting mode that combines wide and narrow rows of rice transplanters, weeders, and harvesters, and using wide-heading, narrow-track harvesters, inter-row weeders, and high-clearance plant protection machines, combined with field grid filling operation path planning, the entire process of planting, managing, and harvesting ratooning rice is fully mechanized.

Benefits of technology

It significantly increased the yield of ratooning rice, reduced the crushing rate, ensured the germination rate of dormant buds, and realized the mechanization of ratooning rice planting, management and harvesting, improved sowing precision and efficiency, and reduced manual weeding time.

Abstract

An agricultural machinery and agronomy integrated production mode for improving the unit yield of ratoon rice, comprising: returning green manure to fields; sowing and seedling raising; wide-row and narrow-row alternating transplanting of next-season ratoon rice; during a growth period of the first crop / ratoon crop of rice for the next season, performing physical weeding in the spacings between rows of wide-row planting and in spacing areas between wide rows and narrow rows, and performing pest and disease control by means of a high-clearance plant protection machine; and harvesting the first crop / ratoon crop of rice using a ratoon rice combine harvester with a wide header and narrow crawler tracks, wherein a working track width of a wide-narrow row rice transplanter, a working track width of the high-clearance plant protection machine, a working track width of an inter-row cultivation and weeding machine, and a crawler track gauge of the ratoon rice combine harvester with a wide header and narrow crawler tracks are the same. Further disclosed are an inter-row cultivation and weeding machine that can be used in the integrated production mode, a control method for the inter-row cultivation and weeding machine, and a combine harvester that can be used in the integrated production mode. The use of the integrated production mode can reduce a trampling rate of ratoon rice during a period from transplanting to harvesting, and can increase the germination rate of dormant buds of the ratoon rice.
