- 摘要:
- 通过盆栽条件下对土壤水分设置5 个水平, 分别对大豆营养生长期、花期、荚期和鼓粒期4个关键生育期进行水分控制, 研究对大豆子粒产量的影响。试验结果为:营养生长期干旱可减产19 .42 %-21 .11 %, 涝灾可减产6 .97 %;花期干旱可减产17 .70 %-25 .92 %, 涝灾可减产14 .91 %;荚期干旱可减产23 .77 %-33 .89 %, 涝灾可减产13 .70 %;鼓粒期干旱可减产12 .25 %-40 .61 %, 涝灾可减产10 .10 %。同一水分条件对不同生育期进行处理结果是:各个生育期进行“特涝”处理, 其子粒减产程度没有差异;在干旱条件, 不同生育期处理产量损失大小结果为:荚期>花期>营养生长期>鼓粒期。
- Abstract:
- In this pot experiment , the soil moisture were controlled by 5 levels , and the effects of the moisture , whichwere controlled in vegetative stage , flowering stage , podding stage and podfilling stage , on soybean yields were studiedrespectively .The results showsed that a long term drought in vegetative stage made soybean yields derease to 19 .62 %-21 .11 % and the water logging to 6 .97 %;the drought in flowering stage to 19 .18 %-27 .26 % and the water logging to14 .9 %;the drought in the podding stage to 23 .80 %-33 .84 % and the water logging to 13 .67 %;the drought in thepodfilling stage to 12 .20 %-40 .59 %and the water logging to 10 .03 %.The results also showed that there were no differanceof soybean yields in the most water logging treatment in every srowing stage .In drought condition , the loss of soybeanyields in different srowing period took turns less to be in podding , flower , vegetative and podfillings stage .
