大豆高产优质同步栽培技术体系的研究 Ⅰ.不同播法和肥料对大豆产量及脂肪含量和脂肪产量的影响

Study on Cultural Techniques for High Oil Content and Grain Yield of Soybean Ⅰ. Effects of Different Planting Pattern and Fertilizers on Grain Yield, Oil Yield and Oil Content

采用高油大豆品种黑农 4 1,穴播、两垄一沟、双条播 (对照 ) ;磁化肥、生物肥、磷酸二铵 +硫酸钾 (对照 )进行播法和肥料二因素试验。结果表明 :穴播的产量、脂肪含量和脂肪产量均高于双条播和两垄一沟 ,其差异达到了极显著水平。生物肥的产量、脂肪含量和脂肪产量高于磁化肥和磷酸二铵 +钾肥 ,并与对照的差异达到了极显著水平。穴播×磁化肥和穴播×生物肥处理组合对黑农 4 1的产量、脂肪含量及脂肪产量具有较好的正向效应 ,是本试验较佳的组配方式。

High oil content and high yield of soybean cultivar, Heinong 41, was used in this study. Planting patterns were hill sowing, two ridges a furrow and double drilling (CK). Fertilizers were magnetized fertilizer, bacterium fertilizer and mixture of diammonium phosphate and potassium sulphate (CK). Two-factor experiment with planting pattern and fertilizer was conducted in hilly field and indent field in 3 sites. The results showed that the grain yield, oil content and oil yield of Heinong 41 in hill sowing was higher than those in 2 other planting patterns, and the difference reached 1% significance level. The gain yield, oil content and oil yield of Heinong 41 with bacterium fertilizer was higher than those with 2 other fertilizers and the difference reached 1% significant level. The combination of hill sowing and magnetized fertilizer, hill sowing and bacterium fertilizer produced positive effects to the grain yield, oil content and oil yield of Heinong 41.
