Method of changing dry land to paddy field in mountainous yellow soil area

Abstract

The invention provides a method for transforming dry land into paddy fields in mountainous yellow soil areas. The steps include: determining the scope of the field to be transformed, peeling off the topsoil and leveling the base, building the ridge, backfilling the topsoil and leveling the field; soaking the field for beating; transplanting rice seedlings for cultivation, and adjusting the field according to the traditional method Carry out transplanting and daily management and care. The present invention combines modern tillage with traditional tillage techniques, which can quickly plug leaks, promote water storage in new paddy fields, solve the problem of slow water storage in traditional drought-to-water methods, and promote the formation of high-quality plow bottoms in newly-built paddy fields , which is conducive to the positive succession of newly-built paddy fields, and can also remove the root system of weeds in the field, making the field surface very smooth, which is convenient for the later management of rice planting; more importantly, the method of the present invention can overcome the soil sticking and sealing of newly-built paddy fields, and effectively prevent Rigid seedlings of rice occur.

Description

technical field [0001] The invention relates to paddy field reclamation technology, in particular to a method for transforming dry land into paddy fields in mountainous yellow soil areas. Background technique [0002] With the continuous development of the economy and society and the gradual expansion of the city scale, a large number of good fields and good soil have been expropriated into urban construction land. Policy requirements to ensure the red line of 1.8 billion mu of arable land and national food security, some areas are implementing the relevant policies of changing dry land to paddy fields. The mountainous yellow soil area is mainly distributed in the mid-subtropical humid area. The soil is yellow and rich in hydrated iron oxide. The mountainous yellow soil area where the platform slope is small (the slope is less than 15°) should be comprehensively controlled by mountains, water, and fields. The basic construction of farmland as the center. The invention main...

AI Technical Summary

Problems solved by technology

However, the conventional method of converting dry land to paddy fields and its key technical points are not applicable to the conversion of dry land to paddy fields in mountainous yellow soil regions.

In addition, in terms of conversion of dry land to paddy fields, the water retention rate of newly converted paddy fields has been very low in the first year (usually only 35-50%)
