摘  要：
采用大田随机区组设计,研究了始穗期喷施EDTA、黄腐酸、乙酰水杨酸、CaCl2等抗旱性物质对地膜旱作水稻后期光合性能、干物质积累及产量的影响。结果表明:始穗期喷施EDTA、黄腐酸、乙酰水杨酸、CaC l2能延缓叶片衰老,使地膜旱作水稻后期保持较高功能叶面积指数及叶绿素含量,提高光合效率,增加光合产物积累,促进籽粒灌浆,提高产量,其中乙酰水杨酸处理增产最显著,较对照增产达13.8%。

摘  要：
By randomized block design,the effect of spraying drought resistants during early earing stage on the photosynthesis,and yield of hybrid rice IIyouming 86 and variety Zhongxian 898 cultivated in aerobic soil were studied.The results showed as follows: the functional leaf area index,the content of chlorophyll,the efficiency of photosynthesis,the dry matter,the filling and the yield of rice cultivated in aerobic soil were increased with EDTA,fulvic acid,salicylic acid,Cacl2 were sprayed rice cultivated in aerobic land during early earing stage.Among these,the salicylic acid treatment is the best.The highest yield increase by 13.8%.
