Research on the Pattern of Mixed Cropping of Oilseed Rape and Pea in the Shallow Mountainous Areas of Qinghai Province
Purposes The shallow mountainous areas of Qinghai Province are restricted by the production environment,which makes it impossible to implement rational crop rotation.In view of the real problems of single crop production layout,poor ability to withstand natural disasters,and declining soil fertility in the region,this article made a study of oilseed rape and pea mixed cropping model of enhancing and improving the production performance,nutritional quality,arable land quality,and soil fertility.Method Six oilseed rape and one pea varieties were used as test materials,and a total of 13 treatments of six oilseed rape and one pea mixed and monoculture,7 treatments of one oilseed rape and six pea mixed and monoculture with different sowing quantities and 6 treatments with different mixing methods were set up,to explore the differences in agronomic traits,mixing production performance and seed nutrient quality of two species under different treatments in order to screen out suitable and reasonable oilseed rape and pea mixing modes.Findings"Qing Oil 62"and"Grassland 224"are more reasonable mixed-crop combinations,and when the two species of mixed-crop seeding rate of 0.4 kg per acre and 2.5 kg per acre,respectively,peer mixing,the optimal production performance,the total yield of 266.44-272.24 kg per acre,an increase of 30%-40%over single-crop,oil content of 42.54%,erucic acid content of 0.8%,thioside content of 38.90 micromolecules per gram.272.24 kg per mu,an increase of 30%to 40%over the single crop,rapeseed oil content of 42.54%,erucic acid content of 0.8%,thioglycoside content of 38.90 micromol/g,belonging to the high-quality oilseed rape in the single-low oilseed rape.Conclusions"Qing Oil 62"and"Grassland 224"are more reasonable oilseed rape and pea mixed cropping combinations,more excellent oilseed rape and pea mixed cropping combinations promoted in shallow mountainous areas,which can maximize its superior production performance and excellent nutritional quality under the appropriate mixing ratios and mixing modes,and can provide theoretical basis and technical support for plantation structure adjustment in shallow mountainous areas of Qinghai.
