摘要
应用（１４）Ｃ研究４ｐｕ—３０对水稻光合产物运转及结实的影响，结果表明４ｐｕ—３０抽穗前喷施可提高水稻剑叶光合强度，促进光合产物向穗部的运转，同时可影响穗部结构，增加实粒数，提高结实率和千粒重，４ｐｕ—３０对穗粒结构的影响主要在抽穗前和灌浆初期。抽穗１０天以后施用，无促进作用。
The effect of 4pu 30 on photosynthate transportation and seed setting of rice was studied by using (14) C.The results showed that the photosynthetic intensity of nag leaf and photosynthate transportation rate increased through spraying 4pn 30 during heading stage. Meanwhile, Filled grain Per spike, setting percentage and 1000 grain weight also improved. The effect of 4pu 30 on rice spike structure were at the period before heading and early filling stage. It had no effect in ten days after heading stage.
