油菜草谷比和秸秆可收集系数监测研究
Monitoring Study on Straw-to-grain Ratio and Collectable Coefficient of Rapeseed Straw
摘要
Abstract
Accurate quantification of straw resource availability and collectable yield is of great signifi-cance for scientific research and policy formulation.In response to the lack of research and data accu-mulation on the calculation of the straw-to-grain ratio(SGR)and collectable coefficient(CC)of rape-seed,taking Luoping County,Yunnan Province,the largest rapeseed production area in Southwest Chi-na with about 850,000 acres of rapeseed fields,as the research area,annual measurements were con-ducted on SGR and CC of five administrative villages in the county for three consecutive years to study the characteristics of rapeseed straw collection in Luoping County and explore the changes in SGR and CC.The monitoring research results show that SGR decreased from 2.019 8 in 2022 to 1.726 6 in 2024 and the CCincreased from 0.671 8 in 2022 to 0.724 6 in 2024.关键词
