Annual field-returning shifting planting method for wheat corn twice-harvested straws

Abstract

The invention belongs to the technical field of crop cultivation and especially relates to an annual field-returning shifting planting method for wheat corn twice-harvested straws. The annual field-returning shifting planting method for wheat corn twice-harvested straws comprises the following steps: harvesting wheat by adopting a wheat combined harvester after the wheat is mature; distributing the straws in a stripped form on the surface of the soil; simultaneously applying fertilizer and sowing between the lines of wheat stubbles by adopting a corn no-tillage combined seed and fertilizer drill; harvesting corn by adopting a corn combined harvester after the corn is mature; cutting the corn straws and roots by a rotating cutter of the corn combined harvester and uniformly spreading on the earth surface; simultaneously deeply scarifying, rotating cultivating the seeding strips, deeply applying fertilizer, sowing wheat and pressing after planting by adopting a wheat deep scarification strip rotating cultivating combined seed and fertilizer drill. According to the annual field-returning shifting planting method for wheat corn twice-harvested straws provided by the invention, the crop straws can be returned to the field annually, the environmental pollution caused by burning the straws is reduced, the organic content of the soil is increased, the absorption and utilization for the soil water and nutrient of the crop root system are benefited and the yield increasing and synergism effects are obvious.

Description

technical field

[0001] The invention belongs to the technical field of crop farming and cultivation, and in particular relates to a method for planting in rotation by returning wheat and corn double-ripe stalks to the field every year. Background technique

[0002] The North China Plain is the main grain producing area in my country. The main planting mode is wheat-corn twice a year. The climate resources and soil conditions in this area are more suitable for wheat and corn planting. The annual planting area of ​​winter wheat is 15.882 million hectares, and the planting area of ​​corn is 10.393 million hectares. hectares, the two-cropping planting mode of wheat and jade in one year accounts for more than 80% of the total sown area of ​​crops in this agricultural area. With the increase of crop yield, the output of straw continues to increase. Therefore, the rational use of straw resources not only involves soil fertility, soil and water conservation, environmental safety, and...

[0028] Embodiment 1 The method for planting rotation of wheat and corn double-ripe stalks returning to the field on an annual basis comprises the following steps:

[0029] (1) After the wheat is mature, it is harvested by a wheat combine harvester. When harvesting, the wheat straw can be chopped into 6-7cm small pieces by the harvester, and distributed in strips on the soil surface.

[0030] (2) After the wheat has been harvested, use the corn no-tillage precision fertilization planter to apply base fertilizer and precision seeding, which is completed once; the sowing row spacing is 60 cm, and the depth of sowing is 5 cm; the base fertilizer is 9 kg of diammonium phosphate per mu, 16 kg of potassium sulfate, Urea 10kg, zinc sulfate 1kg.

[0031] (3) The relative moisture content of the soil suitable for corn sowing is 70% to 75%. If the moisture content is insufficient, the "hood water" should be irrigated in time after sowing to ensure sufficient bottom moisture, early seed g...

[0045] Example 4 From 2013 to 2014, the method of the present invention was adopted in the experimental base of the Crop Science Research Institute of the Chinese Academy of Agricultural Sciences in Xinxiang County, Henan Province. Wheat and corn stalks were returned to the field every year, and strip rotary tillage was planted after deep loosening in the wheat season, and no-tillage in the corn season. For sowing, 7960 yuan / ha was invested in the whole growth period of wheat, the output was 8474.4kg / ha, the output value was 20338.6 yuan / ha, and the net income was 12378.6 yuan / ha; the input of corn was 7815 yuan / ha during the whole growth period, the output was 9919.1kg / ha, and the output value was 20830.1 yuan / ha, the net income is 13015.1 yuan / ha; the annual income is 25393.7 yuan / ha. In the comparative field using the traditional method, under the condition of removing wheat and corn stalks or direct burning, sowing after rotary tillage in the wheat season and no-tillage so...
