Embodiment 1

[0027] Provide a farming method for returning full corn stalks to the field. Take the farming method of returning full corn stalks to the field at the Fanjiatun Xiangshan Village Experimental Station of Jilin Academy of Agricultural Sciences in 2018 as an example. The main operation steps are as follows:

[0028] Step 1: Straw treatment. Harvest the mature corn in the autumn of 2017 with a corn harvester, crush the straw, and spread it evenly on the ground.

[0029] Step 2: Soil preparation operation, subsoiling and rotary tillage operations, breaking the bottom of the plow through subsoiling, deepening the plow layer, mixing the crushed straw and soil through rotary tillage, so that part of the crushed straw is still evenly covered on the surface, Among them, the combined soil preparation machine can be used for subsoiling and rotary tillage land preparation operations, and the subsoiler and rotary tiller can also be used for separate operations, subsoiling first and then rota...

Embodiment 2

[0041] Provide a farming method for returning full corn stalks to the field. Take the farming method of returning full corn straw to the field at the Fanjiatun Xiangshan Village Experimental Station of Jilin Academy of Agricultural Sciences in 2019 as an example. The main operation steps are as follows:

[0042] Step 1: Straw treatment. Harvest the mature corn in the autumn of 2018 with a corn harvester, crush the straw, and spread it evenly on the ground.

[0043] Step 2: Soil preparation operation, subsoiling and rotary tillage operations, breaking the bottom of the plow through subsoiling, deepening the plow layer, mixing the crushed straw and soil through rotary tillage, so that part of the crushed straw is still evenly covered on the surface, Among them, the combined soil preparation machine can be used for subsoiling and rotary tillage land preparation operations, and the subsoiler and rotary tiller can also be used for separate operations, subsoiling first and then rotar...

Abstract

The invention discloses a cultivation method for returning all corn straw to a field. The cultivation method comprises the following steps of S1, after corn harvesting, crushing the straw, and uniformly scattering the crushed straw on the ground surface; S2, after the step S1 is executed, performing deep scarification and rotary tillage operation, breaking a plow pan through deep scarification, deepening a plough layer, mixing and stirring the crushed straw and soil through rotary tillage, and enabling part of the crushed straw to still evenly cover the ground surface; S3, after the step S2 isexecuted, when the temperature of the soil with the depth of 5-10 cm stably reaches 10 DEG C or above, directly starting sowing, compacting and fertilizing; and S4, after the step S3 is executed, conducting field management, wherein field management mainly includes weed, pest and disease prevention and chemical control for lodging prevention. On the basis, the cultivation method balance the double-high effect of temperature and moisture of other farming manners, the emergence rate is ensured, the cost can be saved, and the economic benefit is increased.

Description

technical field [0001] The invention relates to the technical field of farmland farming, in particular to a farming method for returning full corn stalks to the field. Background technique [0002] The Northeast is known as the "Golden Corn Belt". It is the main soybean producing area in China, and its total grain output accounts for a quarter of the country's total grain output. It is the largest commercial grain base in China. However, the unreasonable farming system of "emphasizing use and neglecting cultivation" for a long time has led to serious degradation of black soil quality and decreased soil productivity, which has seriously restricted the sustainable development of agriculture in Northeast China. [0003] Corn is the largest grain crop in Northeast China. The sown area of ​​corn in Northeast China is 230 million mu, accounting for 50% of the total arable land, and the annual output of straw is 170 million tons. However, the proportion of straw returned to the fi...
