在江苏沿海地区啤酒大麦上施用改土灭菌增产素PS—105，使啤酒大麦的分蘖期、拨节期、抽穗期、成熟期提早3～5天，成穗率也显著提高，啤酒大麦原麦品质提高到国标二级以上。每公顷施用PS—105375kg加上1／2常规氮、磷用量，基本满足啤酒大麦各个时期对氮、磷营养的需求，达到和超过常规施肥的增产效果。施用PS—105还可活化土壤中的无机营养，可以逐步提高土壤肥力。 In the coastal areas of Jiangsu beer barley soil modified sterilized yield PS-105, so that the barley tillering stage, diallelization, heading, maturity early 3 to 5 days, spike rate also significantly increased, beer barley Wheat quality to GB two or more. The application of PS-105375kg per hectare plus 1/2 normal nitrogen and phosphorous basically satisfied the requirement of nitrogen and phosphorus nutrition in each stage of beer barley, and reached and exceeded the yield increase of conventional fertilization. Application of PS-105 can also activate inorganic nutrients in the soil, can gradually increase soil fertility.
