Embodiment 1

[0083] 1. Overview of the research area

[0084] The research area is set as the one-crop area in China's high latitudes (>35N) (Liu Xunhao et al., 1987; Liu Xunhao, 2002), including the one-crop area of ​​cool and warm crops in the foothills of the Greater and Lesser Khingan Mountains, and the one-crop area of ​​warm and cool crops in the Changbai Mountains of the Sanjiang Plain. Ripe area, Liaoji, Ximeng, southeast, Hebei, semi-arid, temperature-loving and ripening areas, Songnen Plain, warm crops-ripe-cooking area, Liaohe Plain, hilly, warm crops-ripe-filling area, Hetao, Houshanba, Shanxi plateau, mountainous semi-arid Cool crops and one ripening area, eastern Loess Plateau prone to drought and warm and one ripening area, eastern Shanxi semi-humid and drought prone and one ripening area, Longzhong Qingdong Ning central and southern loess hills semi-arid and cool crops one ripening area, Weibei Long Eastern semi-humid and drought-prone winter wheat one-cropping fill-in area...

Embodiment 2

[0108] In this example, in 2020, the high-efficiency planting mode of oat grass multiplanting soybean twice a year was tested in Shaoguoyingzi Village, Kaoshan Town, Nong'an County, Changchun City, Jilin Province. Loam soil, the test area is 2 hectares. Potatoes, the previous crop in the experimental plot, were not applied with chemicals that would affect subsequent crops during the planting process. The planting process is as follows:

[0109] (1) Planting oat grass

[0110] 1. Land preparation

[0111] After the crops were harvested in 2019, the method of stubble removal and rotary tillage was used to prepare the land for use.

[0112] 2. Sowing

[0113] The oat variety Baiyan No. 7 is used;

[0114] Sow on March 20, 2020, apply 15kg / mu of special compound fertilizer for corn as base fertilizer, sow in flat cropping, row spacing 14cm, seeding rate 10kg / mu.

[0115] 3. Field management

[0116] Seedlings emerged on April 14, suppressed on May 1, and earing began on Jun...

Embodiment 3

[0131] In this example, in 2020, in Nonglin Village, Maolin Town, Shuangliao City, Jilin Province, the high-efficiency planting mode of double-cropping oat grass and soybeans will be implemented in a year. The land is 123°73' east longitude and 43°68' north latitude. The area is 1.7 hectares. Soybean, the previous crop in the experimental plot, was not applied with herbicides that would affect the growth of subsequent crops during the planting process. The planting process is as follows:

[0132] (1) Planting oat grass

[0133] 1. Land preparation

[0134] After the crops were harvested in 2019, the method of stubble removal and rotary tillage was used to prepare the land for use.

[0135] 2. Sowing

[0136] The oat variety Baiyan No. 7 is used;

[0137] Sow on March 20, 2020, apply corn-specific compound fertilizer 15kg / mu as base fertilizer, sow in flat cropping, row spacing 15cm, seeding rate 10kg / mu.

[0138] 3. Field management

[0139] Seedlings emerged on April 1...

Abstract

The invention discloses a field crop multiple cropping planting method. The planting method comprises the following steps: planting in a medium-temperature zone with northern latitude of 41 degrees 40 minutes to 44 degrees 84 minutes; (1) conducting first-season planting, specifically, sowing oats, wheat, peas, flax or rape in late March; and (2) conducting multiple cropping of soybean or corn. In the implementation process, the land utilization rate is effectively increased, the use amount of chemical fertilizer and pesticide is reduced, produced soybeans are high-oil soybeans, the quality of the soybeans is improved, farmer benefits are increased, as the oat grass emerges early, green earth surface coverage can be formed in mid-to-late April and is earlier than one-season corn by one month, black soil loss caused by strong wind erosion in early spring is reduced, and the black soil and the ecological environment can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a planting method for multiple planting of field crops. Background technique [0002] Oat grass is a plant of the genus Oat Grass in the Poaceae family, an annual grain and forage crop. Oat grass has a short growth period and does not have strict requirements on soil. When used for grazing, oat grass has a slightly bitter taste, poor palatability, tall plants, thin stems, and more leaves, so it is suitable for making hay after cutting. Cutting green fodder should be used at the heading stage, when the protein content is high, and the grass yield is also high; the prepared hay can be harvested at the flowering stage, which can increase the harvest. High-quality oat grass plays an increasingly important role in the development of my country's animal husbandry, and my country's demand for oat grass is also increasing. According to statistics, the number of domestic oat grass impor...
