稻田油菜占我县油菜总面积的 6 0 %以上 ,常规以稻田直播为主 ,但直播方式各异。为了加快高产双低油菜在我县的推广步伐 ,我们于 1999～ 2 0 0 0年度进行了“两优 5 86”油菜新品系稻板栽培对比试验。1　材料与方法该试验在我县农科所稻田进行。砂壤土 ,肥力中等 ,试验设 3次重 Paddy field rape accounted for more than 60% of the total area of ​​rapeseed in our county. Conventional live-based direct rice, but broadcast live in different ways. In order to speed up the promotion of high-yield double-low rapeseed in our county, we conducted a comparative experiment on the cultivation of a new rapeseed cultivar “Liangyou586” from 1999 to 2000. 1 Materials and Methods The experiment was carried out in the rice fields of our county agricultural science institute.
