Planting method of harvesting both arrhenatherum elatius and feed brassica napus in high-altitude cold region

Abstract

The invention relates to the technical field of artificial grassland planting, in particular to a planting method of harvesting both arrhenatherum elatius and feed brassica napus in a high-altitude cold region. The main technology includes the steps that when 10 cm of early spring soil defrosts, arrhenatherum elatius is sowed and is harvested in a grain filling stage; then, root systems and tillers during first harvest are removed, no land needs to be levelled, feed brassica napus is directly resowed and is harvested before a final flowering stage. According to the technology, the high-altitude cold region has the climatic features of being low in temperature, windy, sandy, short in frost-free period, limited in accumulated temperature and the like during early spring, and the climatic features of the high-altitude cold region are comprehensively taken into account; arrhenatherum elatius and feed brassica napus are sowed in sequence in two rounds, effective accumulated temperature, annual sunshine duration and the like in the high-altitude cold region are fully utilized, the soil utilization efficiency of unit area is improved, and the yield of arrhenatherum elatius and the yield of feed brassica napus are increased. By adopting the technology in the high-altitude cold region, the problem of prataculture and stockbreeding development weakness in the high-altitude cold region, namely insufficient high-quality pasture supply can be solved to the maximum degree, high-quality pasture is provided for local prataculture and stockbreeding development, and then rapid and healthy prataculture and stockbreeding development is promoted.

Description

technical field [0001] The invention relates to the technical field of artificial grassland planting, in particular to a planting method of oat grass and forage rapeseed in high-latitude cold regions. Background technique [0002] Oats, belonging to the genus Avena L. in the family Poaceae in plant classification, are annual grain and feed crops. The most widely used in production are naked oats (A.nuda L.) and leather oats (A.sativa L.). High-quality oat grass plays an increasingly important role in the development of my country's animal husbandry, especially in areas lacking high-quality forage in alpine regions. According to statistics, the import volume of oat grass increased from 1,500 tons in 2008 to 308,100 tons in 2017. [0003] Rapeseed is not only an important oil crop, but because of its fast growth and high vegetative yield, its pillars can be used as green fodder, green manure and silage. Plays an important role in forage rotations, organic farms and sustaina...

Problems solved by technology

Because wheat, oats, etc. of Gramineae and rapeseed cannot be continuously cropped, the use of land is limited
