Three-year shifting mechanizaxion cultivation method of northeast ridge culture intertilled crop water reservoir moisture retension

Abstract

A mechanized cultivation method with three-year rotation of crops for the northeast features that for the first year, the field is prepared in the later autum, the seeds are sowed in the spring and the crops are harvested in the autum, for the second year, the stubbles are broken and returned back to field in the later auttom, seeds are sowed in the spring and the crops are harvested in the autum, and for the third year, the stubbles are broken in the field and the seeds are sowed in the spring, and the crops are harvested in the autum. It can preserve the moisture in soil for high yield.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a method for cultivating crops. Background technique [0002] The traditional ridge farming methods in dry fields include buckle seeding and squid seedling. Seed buttoning is to turn up the stubble and soil on the ridge platform and buckle it into the original ridge, then sow the seeds on the new soil in the ridge, and then turn up the wet soil on the ridge platform and cover the seeds to form a new ridge , a ditch was formed at the original ridge platform. The seedling is to dig off the root stubble on the ridge first, and then sow on the original ridge platform. The deduction seeds have gradually disappeared due to serious moisture loss, and the succulent seeds are still used. [0003] With the development of agricultural mechanization, there are two current farming methods. One is to raise ridges after flat sowing: the original ridges are turned over and raked, and the spr...

AI Technical Summary

Problems solved by technology

The disadvantage of the above-mentioned "three, three" rotation farming method is the lack of straw returning to the field, which makes it difficult to ensure the sustainable use of the black soil in the Northeast

There are also deficiencies in the alternate wide and narrow row fallow farming method. Some agricultural machinery related to ridge spacing, such as corn harvesters, are difficult to adapt to the narrow row spacing requirements.
