不同播期对夏播高粱生育期及产量的影响
Effects of different sowing dates on the growth stages and yield of summer sorghum
摘要
Abstract
[Objective]In order to research the effects of different sowing dates on the growth stages and yield of summer sorghum.[Methods]Using 5 sowing dates of randomized block design of summer sorghum hybrid Jinza 30,the effects of different sowing dates on growth stages,yield of summer sorghum were studied.[Results]With the delay of sowing date,the growth process was postponed,the growing period was lengthened.Sowing date postponed for 1 days,the growth period extended to 0.48 days;panicles,grains per spike and 1000-grain weight decreased as well.Yield decreased 8.3％ to 21.3％ under the condition of later sowing.By correlation analysis,accumulated temperature appeared highly significant correlation with yield,mean daily temperature appeared significant correlation with yield,the relationship between precipitation and yield were positively correlated.[Conclusion] The suitable sowing period for summer sorghum Jinza 30 was from June 15th to June 30th in the region of Jinzhong.关键词
