The Influence of Sowing Period and Density on Main Agronomic Characters and Yield of Shidou No.4
In order to give full play to yield potential of the summer sowing soybean Shidou No.4, completely randomized design was executed with two factors (sowing period and density) and three levels (sowing period of June 15, June 25 and July 5, density of 18.0 ×104 plants/hm2, 22.5 ×104 plants/hm2 and 27.0 ×104 plants/hm2), which analyzed the influence on agronomic characters and yield of Shidou No .4 with different sowing periodsand densities, and the suitable combination of sowing period and density for high -yield cultivation was selected.The results indicated that sowing period had higher impact on the growth , development and yield of soybeanthan that of density, and in a certain range of sowing period, density had no significant effect on growth and yield of soybean. The suitable combination of sowing period and density for high-yield cultivation of Shidou No.4was sowing period of June 15 and density of 18.0 ×104 -27.0 ×104 plants/hm2, and the highest production was achieved under the sowing period of June 15 and density of 27.0 ×104 plants/hm2.
