specific Embodiment approach 1

[0042] Specific embodiment 1: The method for high-efficiency crop rotation and cultivation of corn and soybean in the northeast region of this embodiment includes the following steps:

[0043] Step 1. Autumn preparation

[0044] 1. Timing of site preparation: Choose to proceed with site preparation in autumn when the soil temperature at a depth of 10cm in the black soil farmland in the northeast drops to and stabilizes at 4.6℃;

[0045] 2. Soil preparation machinery: use power locomotives with more than 200 horsepower to pull related soil preparation machinery for autumn soil preparation;

[0046] 3. Mechanical stubble removal: Use a corn combine harvester with a straw crushing device to directly crush the stalks while harvesting the corn. The stubble height is less than 25cm. Before the start of soil preparation, directly use a 200-horsepower power locomotive to pull the corn stubble machine for one-time harvesting. Stubble, so that the farmland soil is in a state of waiting;

[0047]...

specific Embodiment approach 2

[0069] Specific embodiment two: this embodiment is different from specific embodiment one in that: the power locomotive with 200 horsepower or more is Deere 7830, Deere 7930, Deere 9320, Case 430 or M190. Others are the same as the first embodiment.

specific Embodiment approach 3

[0070] Specific embodiment three: This embodiment is different from specific embodiment one or two in that the length of the straw crushed in step 1 three is 18-22 mm, and the straw is evenly thrown in the field. Others are the same as the first or second embodiment.

Abstract

The invention provides an efficient rotation cropping method for corn and soybeans in the Northeast region, and relates to an efficient rotation cropping method for corn and soybeans. The mechanized and scale corn-soybean rotation cropping method is formed by taking whole process mechanization as a basis, taking scale application as a premise and playing the traditional advantages of planting the soybeans in the Northeast cold region. The method comprises the steps of 1 land preparing in autumn, 2 ridging in autumn, 3 compacting, 4 variety and sowing time selecting, 5 fertilizing, 6 chemical weeding, 7 intertillage managing, 8 pest controlling and 9 lodging preventing through chemical control. According to the method, fertilizer can be saved, pesticide application amount can be decreased, the water use efficiency is improved, the grain yield is increased, and the grain production capacity is stabilized. The method is applied to the field of crop cultivation.

Description

Technical field [0001] The invention relates to a high-efficiency rotation cultivation method for corn and soybeans. Background technique [0002] The cold northeast area is located in high latitude and high cold areas, including northern Heilongjiang, the fourth and fifth accumulated temperature zones in northeastern Inner Mongolia and the mountainous areas in eastern Jilin. These areas have accumulated temperatures of ≥10°C between 1900-2300°C, long and severe winters, and short summers. The frost-free period is about 100 days, with large changes in day and night temperature, and crop production is easily affected by disasters such as low temperature damage and early frost. Moreover, due to cross-regional planting of corn, continuous cropping is common, resulting in soil compaction and serious herbicide residue damage, which affects the increase in yield and quality. Over the years, we have tried single technical measures such as variety selection, fertilizer saving test, drug...
