摘要
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。
By using PS - 105, a material of ameliorating soil, disinfecting and increasing yield, on malting barley in thestal Alea of Jiangsu, not only its tilling stage, jointing stage, heading out stage, ripening stage move up 3 to 5 days, the total eathearing Percentage and the percentage of earbearing tiller adds up remarkablely, but also its cearel quality gets to 2nd grade of national standard. Applying 375kg PS - 105 Per hm2 plus half of common amount of nitrogen, phosphate fertilizer on malting barley could approximaitvely meet its needs of nutrition in every stage, and gain or overtake effects of increasing yield. Additionally. PS - 105 can active inorganic nutrition of soil, and raise soil fetrility.
