Problems solved by technology

[0016] The purpose of the present invention is to overcome the defects of the existing rice stubble spring potato cultivation that is labor-intensive and time-consuming, the season is delayed, the waterlogging is serious, the covering soil layer is thin, and the straw cannot be returned to the field. Simultaneously stabilizing production, the straw burying ditch improves the soil, and provides a cultivation method for rice stubble, spring potatoes, expanding ditch and choking soil, straw burying ditch and improving the bottom of the plow

Embodiment 1

[0029] The following steps are taken for the cultivation method of rice stubble spring potato expansion ditch backed up soil straw burying ditch improvement plow bottom of soil living mud field block.

[0030] A) Ditch digging. After the autumn harvest, dig a field-shaped or well-shaped ditch in the live mud field, dredge the drainage ditch outside the field, reduce the water level in the field, and make the paddy field dry and suitable for farming.

[0031] B) To make a furrow, the width of the furrow is 100cm, and the width of the furrow is 40cm. Plow on both sides of a furrow. The soil block from the furrow is 20cm wide and 13cm thick.

[0032] C) Deep furrows, deep furrows in time after making furrows, hoe the furrows to 25cm below the field surface, and move the soil blocks in the furrows at the same time, stack them into 30cm wide soil ridges, and form two 15cm wide soil ridges with the edge of the furrow , 13cm deep seeding ditch.

[0033] D) Base fertilizer, apply the...

Embodiment 2

[0040] The following steps are taken to improve the plow bottom cultivation method of rice stubble and spring potato with topdressing farm miscellaneous manure, expanding ditch, burying ditch and burying ditch.

[0041] A) Make furrows, from mid-to-late November to early-to-mid-December after the end of autumn harvest and autumn planting, stake out ditches to make furrows on the rice stubble fields. The furrow surface is 100cm wide, and the furrow width is 40cm. Both sides of a furrow are plowed. The soil block from the furrow is 20cm wide and 13cm thick. Plow neatly on the edge of the furrow to form a 13cm high soil ridge.

[0042] B) Deep furrows, deep furrows in time after making furrows, hoe the furrows deep to 25cm below the field surface, move the soil blocks in the furrows at the same time, stack them into 30cm wide soil ridges, and form two 15cm wide soil ridges with the edge of the furrow , 13cm deep seeding ditch.

[0043] C) Base fertilizer, apply the fertilizer in...

Abstract

The invention discloses a method for cultivating a rice stubble spring potato furrow-expanding hilling straw furrow-burying improved plow pan. The method includes the steps of (1) making rectangular land pieces, enabling the widths of the rectangular land piece faces to be 100cm, and enabling the widths of rectangular land piece furrows to be 40cm, (2) timely deepening the furrows after the rectangular land pieces are made, enabling the depths of the rectangular land piece furrows to be 25cm lower than the field faces in a hoed mode, and carrying soil blocks into the rectangular land pieces to form soil ribs with the widths of 30cm to form two seeding furrows with the widths of 15cm and the depths of 13cm between the soil ribs and rectangular land piece-edge soil ribs, (3) applying base fertilizers, (4) seeding two lines of potatoes in each rectangular land piece, and enabling the line distances to be 45cm and the plant distances to be 26cm, (5) covering the rectangular land pieces with soil, clearing the rectangular land piece furrows, flattening the rectangular land piece faces, and covering potato seeds with the soil, (6) carrying out hilling, when the heights of seedlings are about 20cm, expanding the furrows, and carrying out hilling to enable the heights of the hilled positions to be 16-18cm higher than the field faces, (7) burying straw into the furrows, and (8) carrying out management, and achieving daily field management.

Description

technical field [0001] The invention relates to a farming method for returning straws to the field to improve soil, in particular to a farming method for improving plow bottom layers by expanding ditches with straws and burying ditches in southern rice stubble and spring potatoes. Background technique [0002] Potato planting in rice stubble fields in southern my country is a new growth point of my country's grain production. The soil structure of potato stubble is better than that of winter fallow field, which is conducive to early emergence and high yield of rice. Innovative farming methods, high and stable potato yields, and solving the problems of returning straw to the field and deep plowing of paddy fields to improve soil. [0003] At present, rice stubble spring potato cultivation adopts the method of plowing and punching holes for planting, and the specific method includes the following steps. [0004] 1. Plowing, after the autumn harvest and autumn planting, the r...
