    摘要:

    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。

    Abstract:

    Effects of the combined application of N,P,K fertilizer and rhizobium inoculant on yield traits, yield and economic benefit of soybean were studied by randomized block design. The results showed that OPT, OPT-N,OPT-K treatments improved the pods number per plant, seeds number per plant, grain weight per plant of soybeansignificantly, improved the soybean yield and economic benefit. OPT-N treatment had the highest yield with 4352.1 kg/hm2, and net benefit was 18 075.1 yuan/hm2. Compared with conventional fertilization, the yield increased by 29.4%, and net benefit increased by 5103.4 yuan/hm2, so it brought higher profit for farmers.
