钾宝为以色列海法化学公司生产的硝酸钾高效复合肥(Multi-npk12-2-44),含N12％、P_2O_52％及K_2O44％,钾宝所含硝态氮和钾均为作物生长所必需的元素。1999年安徽省阜阳市农业科学研究所引进钾宝在脱毒甘薯上试验,增产效果显著。供试品种为“皖薯1号”和“阜88073”,试验采用随机区组设计,3次重复,小区面积20m~2。测产取样长2m,垄宽0.85m,计1.7m~2。处理Ⅰ为每hm~2基施钾宝150kg,处理Ⅱ为对照(CK)未施钾宝。前茬作物为马铃薯,土
Potassium nitrate is a potassium nitrate efficient compound fertilizer (Multi-npk12-2-44) produced by Israel Haifa Chemical Co., which contains N12%, P_2O_52% and K_2O44%. Nitrate and potassium contained in Potassium are all necessary for crop growth Elements. In 1999, Fuyang City, Anhui Province Institute of Agricultural Sciences introduced potassium Po in the virus-free sweet potato on the test, a significant yield increase. The tested varieties were “Wanshu 1” and “Fu 88073”. The randomized block design was used in the experiment, with three replications and the plot size was 20m ~ 2. Production sampling length 2m, ridge width 0.85m, total 1.7m ~ 2. TreatmentⅠwas 150kg potassium per hm ~ 2 and treatmentⅡwas not potassium fertilization (CK). Crops before the crop is potato, soil
