采用随机区组设计,研究了氮、磷、钾肥配施根瘤菌剂对大豆产量性状、产量和经济效益的影响。结果表明:OPT、OPT-N、OPT-K处理能显著改善大豆的单株荚数、单株粒数和单株粒重,提高大豆产量和经济效益。以OPT-N处理产量最高为4352.1 kg/hm2,纯收益为18 075.1元/hm2,比常规施肥模式产量提高29.4%,纯收益提高5103.4元/hm2,可以为农户带来较高的收益。
Randomized block design was used to study the effects of nitrogen, phosphorus and potassium fertilizers on soybean yield, yield and economic benefits. The results showed that OPT, OPT-N and OPT-K treatments could significantly improve soybean pod number per plant, grain number per plant and grain weight per plant, and increase soybean yield and economic benefits. The highest yield of OPT-N treatment was 4352.1 kg / hm2, and the net income was 18 075.1 yuan / hm2, which was 29.4% more than the conventional fertilization mode and the net income increased by 5103.4 yuan / hm2, which could bring higher returns to farmers.
