过去,我省种植蓖麻较粗放,生产上没有选种、留种习惯,品种混杂退化严重,植株整齐度很差,在同一块蓖麻田里有红秆,也有绿秆;成熟期有早,也有晚。不仅给田间管理带来很多不便,而且降低蓖麻的产量和质量。蓖麻是同株异花授粉作物,借助风力和昆虫传粉,所以混杂的机会更大,加上它是无限花序,分枝部位不同,蒴果成熟
In the past, our province planted castor is more extensive, there is no selection of species, the habit of keeping species, serious deterioration of mixed varieties, plant uniformity is poor, in the same castor field with red stalks, but also green stalks; mature early, There are also late. Not only does it bring a lot of inconvenience to field management, but it also reduces the output and quality of castor. Castor is an allogamy pollination crop, pollinated by wind and insects, so there is a greater chance of promiscuity, coupled with its infinite inflorescence, different branching positions, and capsule maturation
