播期和种植密度对油春1204大豆产量的影响

Effects of Sowing Date and Planting Density on Yield of Soybean Variety Youchun 1204

以2017年审定的油春1204大豆(Glycine max)品种为试验材料,进行不同播期与种植密度(播期5月18日、5月25日和6月1日,密度40万、25万和20万株/hm^2)的裂区试验。结果表明,主区处理间(不同播种时间)油春1204大豆产量的差异达到极显著水平,副区处理间(不同保苗密度)大豆产量差异也达到极显著水平,但播期与密度间的互作对油春1204大豆产量差异的影响未达到显著水平。荆门市种植油春1204大豆的最佳播期与密度组合为5月18日播种、保苗密度为25万株/hm^2。

Taking soybean variety ‘youchun 1204＇（authorized in 2017） as the test material, a two-factor experiment with split plot design was conducted, one factor is sowing date, with 3 levels of May 18 th, May 25 th and June 1 th; another factor is sowing density, with 3 levels of 400 thousand plants/hm2, 250 thousand plants/hm2 and 200 thousand plants/hm2. The results showed that, the difference in soybean yield was extremely significant between different sowing date processing; the difference in soybean yield was extremely significant between different seedling density processing; but the interaction between sowing date and density had no significant effect on the yield difference of soybean variety ‘youchun 1204＇. The best combination of sowing date and planting density in Jinmenwas was May 18 thand 250 thousand plants/hm^2.
