不同有机肥对大豆植株性状、品质和产量的影响

为了为农业废弃物的资源化、肥料化和循环利用提供参考依据,采用大田随机区组试验,以单施化肥和不施肥为对照,研究了以麦草、鸡粪为原料自制的生物有机肥和有机无机复混肥对春播和夏播大豆的植株性状、生育期、产量和品质的影响。结果表明,施用有机无机复混肥能延长大豆生育期、提高大豆的株高、单株分枝数、单株荚数、单株粒数、百粒重、单株粒重、产量及蛋白质和脂肪含量,且与其他处理的差异均达显著或极显著水平;在以上指标中,生物有机肥处理与不施肥处理的差异均显著,但与单施化肥处理的差异不显著。提示有机无机复混肥不仅能促进大豆的生长,而且还能提高大豆的产量和品质;生物有机肥的增产作用与化肥相当,但可以显著提高大豆的品质。

Effects of different organic fertilizer on plant character,quality and yield of soybean

In order to support resource and fertilizer recycling of agricultural waste,the paper have utilized the field randomized block experiment,and analyzed the effects of bio-fertilizer and organic-inorganic fertilizer made by wheat straw and chicken manure on some agronomy character of spring and summer sowing soybean compared with fertilization of chemical fertilizer and no fertilizer.The results showed that,fertilization of the organic-inorganic fertilizer could prolong soybean growth period,and improve plant height,branches,pods per plant,seeds per plant,weight of 100-seed,seeds weight per plant,yield,protein and fat of soybean;the organic-inorganic fertilizer reached significant difference or extremely significant difference compared with the other treatment;but the bio-fertilizer reached significantly difference compared with no fertilizer,the bio-fertilizer did not reach significant difference compared with the chemical fertilizer.The study showed that the organic-inorganic fertilizer not only promoted soybean growth,but also improved yield and quality of soybean;the bio-fertilizer could improve the quality of soybean significance,but the increase yield ability was similar to chemical fertilizer.
