摘要
为了选拔适合四川省种植的籽叶高产的蓖麻品种,连续两年对从浙江引进的3个中杆蓖麻品种的物候期、分支能力和夏伐后籽叶产量等农艺、经济性状进行引种试验。结果表明,"浙蓖1号"属早熟品种,"浙蓖3号"和"浙蓖4号"属中早熟品种,早熟和中早熟蓖麻品种在四川省部分地区一年可以一播两收;3个引进品种每667 m^2的籽产量在116 kg^200 kg,比对照种增产12%~16%,其籽产量与一级分枝穗长、分枝能力成正相关;春播夏伐采叶两季,3个引进品种产叶1586 kg^1902 kg/667 m^2,高于对照种的15%~41%。这3个蓖麻品种具有产叶(籽)量高、分支能力强、可一年两收等特性,其中浙蓖3号综合性状最优,适合在四川省丘陵地区推广种植。
The field evaluation was carried out on 3 castor varieties with medium high stem introduced from Zhejiang Province so as to select castor varieties with high yield of seeds and leaves in Sichuan Province. The phenological periods, agronomic traits and major economic characters were comprehensively evaluated. The results showed that, Zhebi No.1; Zhebi No.3 and Zhebi No.4 were early maturing varieties, they could be sown twice a year in Sichuan. The seed yield of 667 m^2 of the three introduced varieties was higher than that of the control, whenever they were Summer cutting or not. The seed yield was positively correlated with the number of primary branches and branching property. The three castor varieties had excellent properties, and Zhebi No.3 showed best on the comprehensive characters, therefore it is suitable to be planted in the hilly areas of Sichuan Province.
