不同种肥施用量对高油大豆产量及品质的影响

Effects of Different Seed Fertilization on Yield and Quality Traits of High-oil Soybean

为促进大豆高产高效栽培,采用二因素裂区试验设计,研究了不同种肥施用量对高油大豆产量及品质的影响。结果表明:施肥量对高油大豆的农艺性状影响不大,而对产量性状和品质性状影响较大。施肥量在150～300kg.hm-2时,单株荚数、单株粒数、单株粒重、产量及脂肪含量均随着施肥量的增加而增加,蛋白质含量则与之相反。

In order to promote the high yield and high efficient cultivation, the effects of seed fertilization on the high-oil soybean yield and quality traits were studied using a split plot experiment with two factors. The results showed that the seed fertilization had smaller effects on agronomic trait of high-oil soybean, and had larger effects on the yield and quality trait of high-oil soybean. The pods per plant, grains per plant, grain weight per plant, yield and fat content were increased when fertilization increased from 150 to 300 kg. hm-2 ,and the protein content was dropped.
