Wheat corn mechanized ecological fertile soil rotation planting agronomy

Abstract

The invention provides a mechanized ecological fertile soil rotation planting agronomy of wheat and corn, which is characterized in that farmland is divided according to the specifications of 2.4 m in width and 0.3 m in ridge width, and the rotation planting of wheat and corn is carried out in a crop rotation cycle of 5 years. Among them, the wheat sowing adopts the sowing mode of 8 rows per furrow, the seedling width is 12 cm, and the row spacing is 28 cm; The corn stalks are crushed and returned to the field in one year, and the soil is deeply plowed and turned over; the wheat is sown with a seedling belt seeder for wide row spacing and wide seedling belt sowing; the second, third, fourth and fifth wheat sowing in the rotation cycle The seedling belt seeder with straw crushing and returning device at the front is used for sowing with wide row spacing and wide seedling belt; corn seeding is sown with corn seeder with seedling belt cleaner, and the third and fourth years are carried out every other year Interlaced deep loose.

Description

technical field [0001] The invention relates to a new agricultural technique for mechanized ecological planting in a wheat-corn crop rotation area and increasing yield in fertile soil, and belongs to the technical field of crop rotation plowing and sowing. Background technique [0002] At present, there are mainly two cultivation methods in domestic wheat and corn rotation areas. One is the rotation cultivation technology under the traditional intensive cultivation method, that is, corn stalk treatment-deep plowing of farmland-rotary tillage leveling-wheat sowing-wheat Harvesting - straw crushing - deep plowing of farmland - corn sowing - corn harvesting, this planting agronomy is relatively cumbersome, and the entire rotation process is divided too finely, which not only increases the number of agricultural machinery operations and energy consumption, but also leads to serious hardening of the plow bottom of the farmland , the surface soil aggregate structure is finely brok...

Problems solved by technology

[0002] At present, there are mainly two cultivation methods in domestic wheat and corn rotation areas. One is the rotation cultivation technology under the traditional intensive cultivation method, that is, corn stalk treatment-deep plowing of farmland-rotary tillage leveling-wheat sowing-wheat Harvesting - straw crushing - deep plowing of farmland - corn sowing - corn harvesting, this planting agronomy is relatively cumbersome, and the entire rotation process is divided too finely, which not only increases the number of agricultural machinery operations and energy consumption, but also leads to serious hardening of the plow bottom of the farmland , the surface soil aggregate structure is finely broken, soil fertility degradation, serious soil erosion and other problems are not conducive to the stable and high yield of wheat and corn; the other is conservation tillage agronomy, that is, corn harvesting-straw crushing and returning to the field-wheat no-tillage sowing ——wheat harvesting—corn no-tillage sowing, the process only includes corn stalk crushing and returning to the field, wheat no-tillage sowing and corn no-tillage sowing, which simplifies planting agronomy and saves farming time, but perennial conservation tillage will lead to Soil surface compaction, accumulation of diseases and insect pests, increased dependence on pesticides and fertilizers, serious pollution of the atmosphere and farmland ecological environment, and due to water erosion and runoff are not conducive to moisture conservation and water storage in farmland, it is difficult to achieve continuous increase in yield and quality improvement of wheat and corn
