Problems solved by technology

Researches at home and abroad believe that shallow tillage and no-tillage can only increase the organic matter content of the surface soil, but have little effect on the organic matter content of the deep soil, while traditional tillage can reduce soil bulk density and effectively remove weeds, but long-term impl

Embodiment 1

[0026] 1. Spread the straw evenly and return it to the field

[0027] When harvesting wheat, use a wheat combine harvester equipped with a straw cutting and even spreading device at the grass outlet. The height of the stubble is 12-15 cm, and the length of the chopped straw is ≤ 8 cm. If the wheat straw is piled up, it needs to be spread evenly by hand. Corn harvesting is carried out with a corn harvester equipped with a crushing device. When corn is harvested, a corn harvester equipped with a straw crushing device is used to operate, and the straw is crushed and crushed to evenly spread the ground.

[0028] 2. Choice of farming method

[0029] No-tillage is used in the corn season, and rotary tillage and plowing are used alternately in the wheat season. Rotary tillage with a reverse rotary tiller at a depth of 12 to 15 cm, plowing with a three-share plow at a depth of 25 to 30 cm, and leveling with a rotary tiller after tillage.

[0030] 3. Sowing and fertilization technolog...

Abstract

The invention provides a method for improving soil productivity of a wheat-corn crop rotation area of a Yellow River old riverway, and relates to the technical field of crop cultivation. According tothe method, straw returning and tillage are combined, corn season no-tillage, wheat season one-year rotary tillage and next-year ploughing are alternately carried out, the basic soil fertility level of a medium and low-yield field in the Yellow River old riverway is continuously improved, the resource utilization efficiency and the mechanical production level are improved, and the method has important theoretical and practical significance for improving the comprehensive grain production capacity of the medium and low-yield field, is beneficial to increasing the yield of wheat and corn, can maintain and promote slow improvement of soil quality, and is a farming mode for agricultural sustainable development of coastal soil barren areas of the Yellow River old riverway.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for improving soil productivity in a wheat-corn rotation area in the old course of the Yellow River. Background technique [0002] The medium and low-yield fields in Jiangsu Province are mainly concentrated in northern Jiangsu, accounting for about 65% of the total area of ​​the province's medium-low-yield fields. Among them, the old course of the Yellow River is a typical area of ​​medium-low-yield fields in Jiangsu Province. The parent material of the soil is sandy and the flatness is poor. Organic matter and The total nitrogen content is generally low, and the ability to retain water and fertilizer is weak. [0003] The transformation of medium and low-yield fields in my country has always followed the principle of "guidance by classification and continuous management". The polder area proposed the "three separations, two controls" governance stra...
