不同种植密度对五河野生大豆生长及产量的影响

Effects of Different Density to the Growth and Yield of Wuhe Wild Soybean

采用田间试验研究了不同种植密度(3.7万株/hm2、5.2万株/hm2、6.7万株/hm2、8.2万株/hm2、9.7万株/hm2)对五河野生大豆生长及产量的影响。结果表明,不同种植密度对五河野生大豆的生长和产量有一定影响。不同处理间株高、有效分枝起点等性状差异不显著,在密度为8.2万株/hm2时产量最高,达到1600kg/hm2。

The effect of different density（ 37000 plants /hm^2,52000 plants/hm^2,67000 plants/hm^2,82000 plants / hm^2,97000 plants/hm^2） to the growth and yield of Wuhe wild soybeam were studied by field experiment. The results showed that the different density had a little influence to the growth and yield of Wuhe wild soybean. The difference of characters such as the plant height,effective branch began height of different treatments was not significant. The yield of 82000 plants / hm^2 is the max,it was 1600 kg / hm^2.
