【摘要】 探讨不同稀释倍数植物生命素对冬小麦生长及其产量的影响,结果表明,小麦生育期喷施不同稀释倍数生命素均可提高千粒质量、理论产量、有效小穗数、开花期及花后20 d旗叶的SPAD值;且喷施500倍液的生命素可提高小麦千粒质量1 g以上,提高小麦产量7%左右。更多还原

【Abstract】 The results of the study on effect of bios that was deliquated different times on the growth and yield in winter wheat showed that it could improve thousand-grain weight,theoretic yield,efficient spike number and the SPAD number of flag leaves in anthesis and 20 days after anthesis by spraying different concentration bios in the growth period of wheat.And it could improve the thousand-grain weight by more than 1g by spraying bios that was deliquated by 500 times,and improved the yield by about 7% of wheat.更多还原
