播期对不同大豆品种性状与产量的影响
Effects of Sowing Date on Characters and Yield of Different Soybean Varieties
摘要
Abstract
In order to find out the suitable sowing date of soybean in Xingyi City,Guizhou Province,and to provide scientific basis for the selection of delayed sowing soybean varieties suitable for planting after rape and wheat harvest.Soybean varieties Qiandou 10,Ruihuang 2,Qihuang 34,Youchun 1204,Nandou 24,Bilü 2 and Andou 9 were used as experimental materials,five different sowing periods were set up,namely April 22nd,April 29th,May 6th,May 13th and May 20th,and the dynamic change trends of growth period,agronomic traits,yield and components of seven soybean varieties were studied under different sowing periods.At the same time,the correlation analysis method was used to deeply explore the internal coupling relationship between sowing period and soybean agronomic traits and yield.The results showed that the change of sowing date had a significant effect on the growth and yield of soybean.Plant height,effective branch number,effective pod number,seed number per plant,seed weight per plant and yield all increased first and then decreased.Among them,the effective branch number reached the peak value on April 29th(the second sowing period),and the effective pod number and yield reached the highest level on May 6th(the third sowing period).The 100-seed weight decreased gradually with the delay of sowing date,and the highest was reached on April 22nd(the first sowing date).The yield was the highest on May 6th(the third sowing stage)at 3 302.98 kg·ha-1,followed by April 29th(the second sowing stage)at 3 171.43 kg·ha-1.Sowing date was negatively correlated with soybean yield,seed weight per plant and 100-seed weight,soybean yield was positively correlated with effective branch number,effective pod number,seed number per plant and seed weight per plant,and seed weight per plant was positively correlated with effective branch number,effective pod number and seed number per plant.In summary,the suitable sowing date of soybean in Xingyi City of Guizhou Province was early May,and the suitable varieties were Qihuang 34,Youchun 1204,Ruihuang 2 and Andou 9.关键词
