Research on Mixed Sowing Technology of Oats and Peas in Shallow Mountainous Areas of Qinghai Province
In order to find the oat-pea mixed cropping technology model that can significantly improve the production performance,forage nutritional quality and economic benefits in the shallow mountainous areas of Qinghai Province,this article used five oat and one pea varieties as test materials,set up five mixed cropping and six single cropping treatments in accordance with the 8:2 sowing rate,explored the differences in the production performance and nutritional quality of the different treatments,and screened out the optimal mixed cropping combinations that had excellent production performance,nutritional quality and total returns.Then,9 different mixed-crop ratios and 7 different mixed-crop treatments were set up to screen out the suitable mixed-crop ratios and mixed-crop methods that could stably realize double high grain and grass,excellent forage quality and higher total yield.The test results showed that oat"Makuang"and pea"Grassland 224"mixed cropping combination is an excellent grass and bean mixed cropping combination promoted in shallow mountain areas,and can maximize the superior production performance and good nutritional value of forage under the appropriate mixed cropping ratio and mixed cropping method.Under the appropriate mixing ratio and mixing method,it can maximize the superior production performance and excellent nutritional value of forage,and increase a choice for the agricultural structural adjustment and industrial quality and efficiency in the shallow mountainous areas of Qinghai Province.
