摘要
田间试验结果表明,杂交蓖麻的单株果稳数增加时,果穗秃尖增长,有效果穗长度缩短,单稳有效果数量减少,百粒重略有下降,但单株有效果的总数增加,单株产量相应提高。每株留3个一级果稳产量最高,比留1个、2个、4个和5个一级果穗的分别增产78.2%、48.8%、13.2%和11.9%。
The experimental results showed that with the number of ears per plant of hybrid castor increasing, the ear's bald length increased, the available ear length became shorter, the number of effective capsules per ear reduced, 100-kernel weight was lightly reduced, but the total number of effective capsules per plant increased and the vield per plant was raised correspondingly. The yield of 3 ears a plant was the highest, 78. 2% higher than that of one ear a plant.
