Vibrating slurry-lifting and land-preparation method and machine tool of paddy field

Abstract

The invention provides a vibrating slurry-lifting and land-preparation method and a machine tool of a paddy field, and belongs to the agricultural land preparation technology and machinery. The method includes the steps that firstly, under a dry framing condition, shallow plowing work and rotary tillage flattening work are conducted on soil of the paddy field; secondly, water is poured into the soil of the paddy field through a drip-irrigation water-pouring mode; thirdly, under a state that water does not exist on the soil surface, after soil moisture content reaches saturation, patting-suppressing type vibrating slurry-lifting work is conducted on the soil surface of the paddy field with the moisture content reaching a saturation state through the special vibrating slurry-lifting and land-preparation machine tool of the paddy field, so that water 'flower' occurs on the soil surface of the paddy field; fourthly, a slurry layer with the thickness ranging from two centimeters to four centimeters is generated on the soil surface of the paddy field, and the land-preparation work is finished. The machine tool is formed by assembling a vibrating slurry-lifting plate on a rice transplanter. The method is good in water-saving effect, less in work process, high in work efficiency, low in labor intensity, high in rice yield per unit area, and good in quality; the machine tool is simple and reasonable in structure, reliable in use, and capable of achieving joint operation of land-preparation and rice transplanting.

Description

technical field [0001] The invention belongs to an agricultural land preparation operation method and a machine tool, and mainly relates to the paddy field land preparation operation technology and the machine tool used. Background technique [0002] The traditional paddy field preparation method is: plow the ground first under dry farming conditions, then rotary tillage, and then pour water into the paddy field after rotary tillage to soak the field. The grader runs repeatedly to complete the rotary tillage and leveling tillage, reaching the state of the seedbed required for transplanting. The above-mentioned traditional land preparation method not only has the problems of many operating procedures, high labor intensity, low operating efficiency, high operating cost, and large water consumption, but also the thickness of the seedbed soil slurry layer of the above-mentioned method can reach 5-10 cm. When the seedbed soil slurry layer is too thick, the rice root system is in...

AI Technical Summary

Problems solved by technology

The above-mentioned traditional land preparation method not only has the problems of many operating procedures, high labor intensity, low operating efficiency, high operating cost, and large water consumption, but also the thickness of the seedbed soil slurry layer of the above-mentioned method can reach 5-10 cm. When the seedbed soil slurry layer is too thick, the rice root system is in an anaerobic environment, causing premature aging of the root system and plants, and easy lodging, and the rice yield per unit area is low and the quality is poor.
