摘要:
研究了鸭跖草生长发育规律及与大豆竞争关系, 鸭跖草出苗始期为5 月上旬, 高峰期为5 月中下旬, 鸭跖草营养生长的高峰期在7 月中下旬;出苗的最适深度在5cm 以上, 20cm 无出苗。鸭跖草随密度增加, 种内竞争和与大豆竞争逐渐明显。鸭跖草竞争致使大豆减产, 两年结果经SSR检验, 每m240 株产量差异显著, 减产17 .7 %-35 .1 %。回归方程为y =3 .7158 +0 .6481x , r =0 .9794 。
Abstract:
The g row th and the development of Commelina communis L and its competition w ith soybean w erestudied in this paper .The seeding emergence occurs in the middle of May ,w hile it s peak emergence is in the endof the month .The peak period of the vegetative grow th is in the end of July .The depth of 5cm f rom the seeds tothe soil surface is favorable for the seed energence , and no seed emergence w as investig ated in the depth of20cm .As the density of Commelina communis L is increasing in the soybean field , the tension fo r its individualand i ts compet ition w ith soybean are in evidence .For the competi tion f rom the w eed , the soybean yield decreased.With the statistic method of SSR , the result for two years show ed that the decreasing rate of the soybeanyield (y)w as 17 %w hen the density(x)reached the level of 40 plant/m2 .Thei r regression function is asfollowed :y =3 .7185 +0 .6481x , r =0 .9794 .
