specific Embodiment approach 1

[0025] Specific implementation mode one: this implementation mode Northeast black soil farmland mechanization high standard autumn land preparation method, comprises the following steps:

[0026] Step 1. Timing of site preparation: after the harvest in autumn, the soil temperature at a depth of 10 cm in the black soil farmland in Northeast China has dropped to and stabilized at 4.6°C for site preparation;

[0027] Step 2. Soil preparation machinery: Use locomotives with a power of more than 200 horsepower to haul related land preparation machinery for autumn soil preparation;

[0028] Step 3. Mechanical stubble removal: choose a corn combine harvester with a straw crushing device, and directly crush the straw while harvesting the corn. The height of the stubble is less than 25cm. Before the start of site preparation, directly use a power locomotive with more than 200 horsepower to pull the corn stubble machine for one-time use. Stubble, so that the soil of the farmland is in a...

specific Embodiment approach 2

[0034] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the power locomotive with more than 200 horsepower is Deere 7830, Deere 7930, Deere 9320, Case 430 or M190. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0035] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: in step 3, the length of the crushed straw is 18-22 mm, and the straw is evenly thrown in the field. Others are the same as in the first or second embodiment.

Abstract

The invention provides a mechanized high-standard autumn land preparation method for a black soil farmland in Northeast China and relates to an autumn land preparation method for the black soil farmland, aiming at solving the problems that an existing autumn land preparation method cannot be suitable for a cold region of Northeast China, water storage and soil moisture conservation capabilities of cultivated farmland are poor and the volume weight of the soil is not suitable. The method comprises: step 1, selecting land preparation time; step 2, selecting a land preparation machine; step 3, carrying out mechanical stubble ploughing; step 4, deeply plowing in autumn; step 5, deeply loosening in autumn; step 6, harrowing; step 7, ridging in autumn; and step 8, suppressing. According to the method provided by the invention, the soil moisture conservation capability and the stress resistance of the soil of a plough layer are commonly relatively strong, zone spacing tillage is realized and structural features of the plough layer are obvious. The soil of the plough layer is loose and the hardness is smaller than 5kg / cm<2>; and a plough pan is relatively compact and the hardness is 15kh / cm<2>-25kg / cm<2>. The mechanized high-standard autumn land preparation method provided by the invention is used for the field of agricultural cultivation.

Description

technical field [0001] The invention relates to a method for preparing black soil farmland in autumn. Background technique [0002] Black soil farmland is a very fertile and valuable cultivated land resource, which plays an irreplaceable and important role in ensuring national food security, regional ecological environment security and sustainable development of regional agriculture. However, the black soil in Northeast China is heavy in texture, with a clay content of more than 40%. Moreover, soil cultivation has been carried out with light tractors as the main power for a long time. Due to the low power of light tractors (less than 20 horsepower), the depth of stubble removal and rotary tillage is shallow, and the operation range is narrow. It is difficult to loosen the entire plow layer in field operations such as soil preparation, sowing, fertilization, and plowing. The 7 field operations have a strong compaction effect on the soil. The most important thing is that the...
