摘要
用大田随机区组设计研究了叶面喷施 6 苄基腺嘌呤 (6 BA)对旱作水稻衰老及产量的影响。结果表明 ,喷施 6 BA能显著提高旱作水稻叶面积指数及叶绿素含量 ,降低丙二醛 (MDA)含量 ,对旱作水稻有很好的防早衰及增产效果 ,增产幅度最高达 15 2 % ;6 BA喷施浓度以 40~ 5 0mg·L-1为宜 ;
By randomized block design the effect of 6 benzyladenine spray on senescence prevention and yield of dry cultivated rice were studied.The results showed as follows:the early senescence was effectively prevented and the yield was significantly increased when the leaf area index and the content of chlorophyll were increased after milk ripe stage,while the malonaldehyde was decreased.The highest yield increase reached 15 2%.The best spray concentration was 40 50 mg·L 1 ,and the best period was during its early earing stage.
