不同肥料组合对大豆产量、品质的影响及其经济效益分析

Analysis of different fertilizer modes on biological characters,yield and quality of soybean and their economic efficiency

通过大田试验研究了8种不同肥料组合对大豆的产量性状及其产量、品质的效应。结果表明:90%常规施肥+低浓度生物菌剂+两次叶面肥处理的大豆产量性状最好,产量最高,达3 574.95 kg/hm2,经济效益分析结果表明,该组合肥料净收益最高,为1 578.15元/hm2;大豆籽粒的蛋白质含量和蛋脂总量也高于其他处理,蛋白质、蛋脂总量分别为40.20%和62.43%;脂肪含量在所有处理中处于中等水平,与对照差异达显著水平。处理4肥料组合是当地较为科学的施肥方式。

Field experiment was conducted to analyze effects of eight fertilizer combinations on yield characters and quality,as well as yield of soybean.The results show that different fertilizer combinations had different effects on yield and quality.Compared with CK,treatment 4（90%UF＋L-BOM＋2SF） was the best in yield characters,and the highest yield came to 3 574.95 kg/hm^2.Analysis of comprehensive economic benefit showed that treatment 4 was the best which net profit was 1 578.15 yuan/hm^2.The protein content and the total content of oil and protein of soybean in this treatment were 40.20% and 62.43%,higher than in other treatments,while the oil content was at middle level among all the treatments,reaching significant difference compared with CK.The treatment 4 was a scientific fertilizing mode in the region,which might provide a basis for rational fertilization in the local soybean production.
