磷酸二氢钾,是一种高效磷钾复合肥,其磷钾含量高(含P2O552%,K2O34%),肥效快,于果树叶0喷施效果明显。 从1982年开始,我们在山东文登县 山乡东许家村果业队,对苹果小国光品种连续进行了四年的对比试验,结果表明:从6月中旬到7月下旬,喷2～3次2%的磷酸二氢钾,花枝率比对照增多10.1 Potassium dihydrogen phosphate is a kind of high efficient phosphorus and potassium compound fertilizer with high phosphorus and potassium content (including P2O552% and K2O34%). From 1982 onwards, we conducted a four-year comparative experiment on apple small country light varieties for four consecutive years in the fruit industry team of Xujia Village, Shanxiang, Wendeng County, Shandong Province. The results showed that from mid-June to late July, spraying 2 or 3 times 2% potassium dihydrogen phosphate, nodding rate increased 10.1 than the control
