生物钾肥在水稻“旱抛再”上应用表明:667m~2施用尿素26kg,过磷酸钙50kg加生物钾肥2kg,可提高水稻两季单产196.5kg,净增收入160.30元/667m~2,增产效果与施用进口复合肥(丹麦)80kg/667m~2及国产复混肥(湖北省土肥站)80kg/667m~2差异不显著,生物钾肥与氮肥磷肥配合施用可代替进口复合肥及国产复混肥,具有较好的推广前景。
The application of bio-potash fertilizer in “drought throwing re-use” of rice showed that 667m ~ 2 application of 26kg urea, 50kg superphosphate and 2kg bio-potash fertilizer increased the yield of rice by 196.5kg in two seasons and the net income increased by 160.30 yuan / 667m ~ 2, Compared with 80kg / 667m ~ 2 of imported compound fertilizer (Denmark) and 80kg / 667m ~ 2 of domestic compound fertilizer (soil fertilizer station in Hubei Province), the application of biological potassium fertilizer and nitrogenous fertilizer and phosphate fertilizer could replace imported compound fertilizer and domestic compound fertilizer , With good promotion prospects.
