农民很爱摘油菜花后期的黄叶喂猪或其它牲畜,这样做害多利少。油菜进入角果发育成熟期,菜籽发育饱满及油分含量增加所需的营养有65%以上来自主茎中部的短柄叶。因此,花后期只有保护好这些叶片,使它们顺利进行光合作用,给角果输送充足营养,才能提高菜籽产量及出油率。另外,油菜叶喂牲畜也对牲畜有害。 Farmers love the yellow leaves of rape late to feed pigs and other livestock. Rape into the pod development maturity, rapeseed full and oil content increased nutrition required for more than 65% from the stem of the middle of the short stems.

In addition, rape leaves feed livestock is also harmful to livestock.
