摘要
为了了解青海省甘蓝型商品油菜籽的含油量,连续两年对青海省甘蓝型油菜主产区商品油菜籽的含油量进行调查。结果表明,2009年和2010年的平均含油量分别为47.86%、43.69%,含油量在不同年份间差异显著,与种植地海拔高度存在极显著相关;含油量较高的油菜产区海拔为2 300～2 800 m;不同县市间平均含油量差异显著,互助、大通、湟中、西宁等油菜主产县(市)因海拔较高,其平均含油量高于平安和乐都两县,正常年份这四县市的平均含油量可达到50%。
In order to understand the oil content of commodity rapeseed（Brassica napus L.） in Qinghai province,the oil content of commodity rapeseed from mainly rapeseed production area of Qinghai province was investigated in two years.Results showed that the average oil content was 47.86% and 43.69% in 2009 and 2010 year,respectively.Difference of the oil content was significant between two years（P0.01）,and there was a extremely significant correlation between the commodity rapeseed oil content and planting altitude in east Qinghai（P0.01）.The oil content was higher at altitudes of 2 300～2 800 m than other regions;The average oil content of commodity rapeseed（Brassica napus L.） from different counties had a significant difference.The oil content was higher in Huzhu,Datong,Huangzhong and Xining than in Pingan and Ledu.The average oil content in average year reaches 50% in these four counties.
