Problems solved by technology

[0002] Leguminous pasture fixes nitrogen in the atmosphere through the symbiotic rhizobia and converts it into available nitrogen nutrients in the grassland ecosystem. It plays an important role in improving the nitrogen nutrient balance of the grassland ecosystem. Due to the cold and humid plateau climate, there are very few pasture varieties with high yield and high quality in artificial grassland. Among them, oat single-sowing in alpine pastoral areas can obtain higher pasture yields, but the net ecological System CO2 exchange rate is too low

Embodiment 1

[0021] Example 1: During the two-year experiment period from 2015 to 2016, the factor model number is M1,

[0022] Mixed varieties: oats and arrow peas;

[0023] Mixed sowing ratio: mix oats and arrow tongue peas according to the mixed sowing ratio of 0:150;

[0024] Sowing time: Sowing is carried out from mid-April to early June every year to build artificial grassland;

[0025] Sowing method: (1) Deep plowing, leveling, weeding and other cultivation and management measures are carried out on the cultivated land before sowing; (2) Artificial drilling is adopted, the row spacing is 10cm, and the sowing depth is 5cm; (3) After the seeds of oats and arrow tongue peas are evenly mixed direct seeding;

[0026] Mixed harvesting and cutting: When the oats grow to the earing stage, the stubble height is 5cm for mixed harvesting and cutting.

Embodiment 2

[0027] Example 2: During the two-year experiment period from 2015 to 2016, the factor model number is M2,

[0030] Sowing time: Sowing is carried out from mid-April to early June every year to build artificial grassland;

[0031] Sowing method: (1) Deep plowing, leveling, weeding and other cultivation and management measures are carried out on the cultivated land before sowing; (2) Artificial drilling is adopted, the row spacing is 10cm, and the sowing depth is 5cm; (3) After the seeds of oats and arrow tongue peas are evenly mixed direct seeding;

[0032] Mixed harvesting and cutting: When the oats grow to the earing stage, the stubble height is 5cm for mixed harvesting and cutting.

Embodiment 3

[0033] Example 3: During the two-year experiment period from 2015 to 2016, the factor model number is M3,

Abstract

The invention discloses a method for planting oat and peas in different mixed sowing proportions, and relates to the technical field of leguminous forage cultivation. The method comprises the following steps that cultivated land is ploughed and then raked; high-quality oat and vicia sativa L. are selected and mixed to be uniform; the uniformly mixed oat and vicia sativa L. are subjected to mixed sowing and planting on the raked cultivated land, and artificial grassland is planed; when oat grows to reach the heading stage, stubble mixed harvesting and cutting are conducted. According to the method, the oat and vicia sativa L. of different proportions can be selected according to different altitudes, geological landforms and the like for mixed sowing and planting, so that the net ecosystem CO2 exchange capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of leguminous forage planting, and in particular relates to a method for planting oats and peas in different mixing ratios. Background technique [0002] Leguminous pasture fixes nitrogen in the atmosphere through the symbiotic rhizobia and converts it into available nitrogen nutrients in the grassland ecosystem. It plays an important role in improving the nitrogen nutrient balance of the grassland ecosystem. Due to the cold and humid plateau climate, there are very few pasture varieties with high yield and high quality in artificial grassland. Among them, oat single-sowing in alpine pastoral areas can obtain higher pasture yields, but the net ecological System CO2 exchange rate is too low. Contents of the invention [0003] The object of the present invention is to provide a method for planting oats and peas in different proportions. The method of the present invention is simple and easy to operate. Diff...
