1986～1987两年在贵州六盘水市水城特区杨梅区台沙乡(海拔1900米以上),从3月28日～6月14日,分6期播种春播白菜型低芥酸油菜“82-CI”和甘兰型夏播油菜“云油12”。结果,以5月中下旬播种产量最高,亩产50公斤以上。品种以甘兰型“云油12”为宜。播种方式比较,间套作的比单作长势好,产量高。前套玉米亩产320公斤,收夏油菜63公斤。试验说明,六盘水市海拔2200米以上的高寒山区播种一季夏油菜是可行的,省内其它相似地区也可试验推行。
From 1986 to 1987, the “82-CI” spring-sowed cabbage-type low-erucic acid rapeseed was sown in 6 stages from March 28 to June 14 in Taisha Township, Wanshui District, And sweet-type summer sowing rape “cloud oil 12”. As a result, the highest yield was planted in the middle and late May, with a yield of more than 50 kg per mu. Variety to sweet type “cloud oil 12” is appropriate. Sowing comparison, between sets than the single to grow well, high yield. Set of 320 acres of corn before the set of acres, harvest summer rape 63 kilograms. Test shows that Liupanshui alpine mountainous areas above 2,200 meters above sea level seeding a summer rape is feasible, other similar areas in the province can also test the implementation.
