Method for semi-mechanically transplanting rice stubble rapes under condition of returning all straws

Abstract

A method for semi-mechanically transplanting rice stubble rapes under condition of returning all straws is characterized by including three steps of smashing straws to return to field by straw machinery, ditching, upturning soil and bedding mechanically and arranging and planting the rice stubble rapes on the field in a laborsaving manner. In the first step, a rice crop combined harvester with a straw smashing device and a rice crop throwing device is utilized to harvest and function in returning rice crops to the field in situ, reducing labor for carrying the rice crops and returning the rice crops and preventing upturned soil from falling into ditches; in the second step, a double-side ploughshare type plough machine is utilized to ditch and realize effects of reducing labor and labor intensity and saving labor cost; and in the third step, gently arranging seedlings of the rapes to be close to lateral sides of the upturned soil beside the ditches and on the surface of the field, tightly covering the soil on roots of the seedlings to function in surviving the seedlings of the rapes and enabling the strong seedlings to be premature. The method for semi-mechanically transplanting the rice stubble rapes under condition of returning all straws is a novel simplified rape transplanting method which can save labor cost, reduce labor intensity and is beneficial to premature of the seedlings, and the purposes that mechanization rate in rape planting links is up to 70%, and the straws are all returned to the field are achieved.

Description

technical field [0001] The invention relates to the technical field of rapeseed cultivation, in particular to a labor-saving and labor-saving semi-mechanized transplanting method of rice stubble rapeseed under the condition of fully returning rice straw. Background technique [0002] The winter rapeseed production belt in the Yangtze River Basin is the main rapeseed production area in my country, with rice stubble rapeseed as the main planting method. On the whole, with the acceleration of urbanization and industrialization in this region, the non-agricultural transfer of rural labor has increased, and the development trend of land scale management has accelerated. However, the current rapeseed transplanting technology takes artificial labor as the core, and adopts artificial seedling cultivation and hole-punching transplanting methods, which requires a lot of labor, high labor intensity, and poor economic benefits; The technology has a certain application area, but due to ...

Problems solved by technology

[0013] 3. In the rapeseed transplanting system, mechanized operations are not used in the main agronomic steps such as returning the rice straw to the field in full, ditching and furrowing, and all manual labor is labor-intensive and labor-intensive, which does not save labor and labor. Scale operators use the method on a large scale

In recent years, due to the irreversible trend of labor shortage in rural areas and the rising cost of revitalization, the traditional transplanting method that requires a lot of labor has become the most important limiting factor for the development of rapeseed production in this area.

Due to the rain in late autumn and the irrigation of old-age rice, the soil moisture in the paddy field after rice harvest is high in southern my country before the planting of winter rapeseed, which is not suitable for mechanical rotary tillage, rotary knife mechanical ditching and mechanical transplanting before rapeseed transplanting
