为解决浙江嘉兴平原农田土壤氮素过多 ,致使氮素利用率不高的问题 ,从澳大利亚引进SC2 7微生物土壤增效剂 ,研究对大麦产量和肥效的影响。结果表明 :SC2 7对大麦有增穗增粒的作用 ,提高成穗率 ,提高产量。并能改善啤酒大麦的品质 ,有提高N素利用率的作用。其中尤以减氮区 140 2 5kg/hm2 N素和SC2 730 0 0ml/hm2 拌种最为理想。使用SC2 7对改善土壤和保护环境有重大的作用
In order to solve the problem of too much nitrogen in farmland soils in Jiaxing Plain, Zhejiang Province, the nitrogen utilization rate was not high. The SC2 7 soil microbial synergist was introduced from Australia to study the effects on the yield and fertilizer efficiency of barley. The results showed that SC2 7 had the effect of increasing the number of grains per panicle, increasing the percentage of panicles and increasing the yield of barley. And can improve the quality of beer barley, improve the utilization of N role. Among them, 140 2 5 kg / hm 2 nitrogen and SC 2 730 0 0ml / hm 2 seed dressing were the most suitable for nitrogen reduction. Using SC2 7 has a major impact on improving the soil and protecting the environment
