【摘要】 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更多还原

【Abstract】 Effect of SC27 microbial soil improver improted from Australia on grain yield and fertilizer efficiency in barley was strdied to solute the problem that low N utilization ratio resulted from too high soil N content in fields of Jiaxin, Zhejiang. The results showed that SC27 could increase the number of ear and grain per ear and improve the perentage of earbearing tillers and the grain yield SC27 could also improve the quality of malting barley. Effect in lowered N test region with 140.25kg N/hm 2 and seed dressed with 3000ml/hm 2 SC27 was especially best. So using SC27 had an great influence on soil amelioration and proteeting envir onment.更多还原
