Problems solved by technology

After the corn stalks are returned to the field, if the land is fully plowed or subsoiled, a large amount of crop stalks will be mixed into the plow layer, which will affect the sowing and emergence of the next season's crops, resulting in uneven emergence of spring crops, which will lead to crop yield reduction
At the same time, due to the relatively high hardness of the soil in autumn, especially after the furrows have been rolled for a planting season, the soil in the furrows is severely compacted. Deep loosening of t

Embodiment

[0007] Embodiment: Take corn stalks as an example.

[0008] (1) After the corn is harvested in autumn, the straw is mechanically crushed and thrown to cover the surface of the ridge-cropped land. The length of the crushed straw is less than 20cm, the crushing rate of the straw is greater than 90%, and the height of the stubble is less than 10cm;

[0009] (2) In autumn, carry out subsoiling on the ridge platform, and the subsoiling depth is 25-30cm; at the same time, carry out stubble removal along the subsoiling position of the ridge platform, with a stubble removal width of 24-32cm and a depth of 7-8cm;

[0010] (3) In the spring of the second year, after sowing along the subsoiling and stubble removal belt, subsoiling in furrows is carried out when the crops have 3-4 leaves at the seedling stage, and the subsoiling depth is 20-30cm.

[0011] When crops are harvested, most of the straw crushed and scattered in the ridge area falls into the ridge, and a small part stays on the...

Abstract

The invention discloses a sub-soiling tillage at different times, belonging to the agricultural soil preparation tillage technology. In autumn, ridge-tillage and stubble ploughing operation are carried out on ridge culture land where straws are returned after being smashed; in summer, the furrowing and sub-soiling operation is carried during the seedling stage of the crops. The tillage is scientific and rational in process, is simple and convenient to operate, improves the soil moisture, reduces the power consumption of soil preparation and is beneficial to improving the per unit area yield of the crops.

Description

technical field [0001] The invention belongs to the agricultural land preparation and cultivation technology, and mainly relates to a subsoiling cultivation method for agricultural ridge cultivation land. Background technique [0002] Northeast China is a typical agricultural ridge-farming area, where crops are ripened once a year, and ridge-farming is implemented for upland crops. The local traditional production method is to transport the whole crop straw out of the farmland or smash it back to the field after the crops are harvested in autumn, then plow the land and make ridges, and sow upland crops in the spring of the following year. After the corn stalks are returned to the field, if the land is fully plowed or subsoiled, a large amount of crop stalks will be mixed into the plow layer, which will affect the sowing and emergence of the next season's crops, resulting in uneven emergence of spring crops, which will lead to crop yield reduction. At the same time, due to t...
