蓖麻子粒含油率高达50%以上,主要用于生产高级润滑油,是医药、航空、机械、化工、纺织、制革、农药、肥料等工业的重要原料。蓖麻杂交种杂种优势很强,增产幅度很大,一般比常规品种增产15%～50%,具有巨大的增产潜力。其主要制种技术是: 1 做好播前准备 1.1 选地隔离。蓖麻制种田应选地势平坦、土层深厚、土质肥沃、理化性状良好、排灌方便的地块较好。为保证种子纯度,应采取隔离措施,建立隔离区的目的,是防止非父本花粉侵染授粉,降低种子纯度。蓖麻传粉的主要媒介是风,风 Castor seed oil content as high as 50%, mainly for the production of advanced lubricants, is the pharmaceutical, aviation, machinery, chemicals, textiles, leather, pesticides, fertilizers and other industries an important raw material. The hybrids of castor have the advantages of strong heterosis and large yield increase, generally yielding 15% ~ 50% more than that of the conventional varieties, and have great yield potentials. The main seed production technology is: 1 prepared to broadcast 1.1 to choose the isolation. Castor-made farming should be flat topography, deep soil, fertile soil, good physical and chemical properties, drainage and irrigation convenient plots better. In order to ensure the purity of the seeds, isolation measures should be taken. The purpose of establishing the isolation zone is to prevent pollination of non-male pollen invaders and reduce seed purity. Castor pollination is the main medium of wind, wind
