一、试验目的我地区日光温室蔬菜上多用复配磷酸二氢钾进行追肥,由于复配磷酸二氢钾与磷酸二氢钾工艺流程不同,为几种化合物掺混而成,价格较低,农户大多施用此类。但这种所谓复配的磷酸二氢钾中含大量氯离子,特别是我地区土壤中含氯离子较多,长期施用势必造成土壤盐份增多,对作物危害较重,为此安排对这两种肥料进行同等价格不同用量的试验,以比较增产增效的作用。
First, the purpose of the test Green vegetables in my area with more potassium dihydrogen phosphate top dressing, due to complex potassium dihydrogen phosphate and potassium dihydrogen phosphate process is different for several compounds blended, lower prices, farmers Mostly use this class. However, this so-called complex of potassium dihydrogen phosphate contains a lot of chloride ions, especially in my area more chloride ions in the soil, long-term use is bound to cause increased soil salt, crop heavier damage, for which arrangements for these two Fertilizer for the same amount of different prices of the experiment, in order to compare the role of increasing production efficiency.
