播期对麦套花生物候期、农艺性状及产量的影响

摘要

Using Jimai 22 and Shanhua 108 as materials,four intercropping stages were set under field conditions,and the effects of sowing date on phenophase,agronomic traits and yield of peanut interplanted with wheat were systematically studied.The results showed that with the postponement of sowing date,each growth stage of peanut delayed and the whole growth period obviously shortened.The pot and seed kernel yield were both the highest at the sowing date of May 25,and the pot yield increased by 7.9%～28.7%compared with the other treatments.Different sowing date treatments had no significant effect on wheat yield.Compre-hensively considering,the best interplanting time of peanut was May 25 .%以济麦22、山花108为试材,在大田条件下设置4个套种时期,系统研究了播期对麦套花生物候期、农艺性状和产量的影响.结果表明:随播期推迟,花生各生育阶段延迟、全生育期明显缩短,不同播期处理的荚果产量和籽仁产量均以5 月25 日播期处理最高,与其他播期处理相比,荚果产量提高了7.9%～28.7%;不同播期处理对小麦产量无显著影响.综合效益分析,本试验条件下花生的最佳套种时期为5 月25 日.
