播种方式对大豆干物质积累与产量影响的研究

Effect of Sowing Methods on Dry Mater Accumulation and Yield in Soybean

试验采用5个处理,3次重复,研究了不同播种方式对大豆干物质积累与产量的影响。结果表明:穴距18cm,每穴3株的播种方式对于干物质的积累较为合适。不同处理对大豆产量性状的影响不同,穴距18 cm,每穴3株的播种方式大豆产量最高,大豆产量与株高、主茎节数、单株生产力及单株荚数呈正相关,而与百粒重呈不显著的负相关。

The effect of different sowing methods on dry matter accumulation and yield in soybean was studied. The results were as follows： The hole distance 18 cm,3 plant per hole in the test was suitable for dry matter accumulation. The effect of different treatment on yield component of soybean was different. There was a single peak appearing at hole distance 18 cm,3 plant per hole. The relationship between yield of soybean and plant height, No. of node on main stem, grain weight per plant, No. of pods was positively, but the relationship between yield of soybean and 100-grain weight was insignificant and negative.
