磷酸二氢钾(KH_2PO4)是一种高速效磷钾复合化肥。为了提高小麦产量,1976年3—4月间,在我社宋庄大队范庄农科组,油坊大队农科队等五个单位,进行了喷施磷酸二氢钾的试验。共20个小区,以喷清水为对照,总试验面积5亩,收前进行了田间考查,收后进行了室内考种。试验田是在大田中设置小区进行的,重复二次,土质、品
Potassium dihydrogen phosphate (KH 2 PO 4) is a high-efficiency phosphorus and potassium compound fertilizer. In order to improve the wheat yield, from March to April 1976, we conducted a test of spraying potassium dihydrogen phosphate in five units of Fanzhuang Agricultural Science Group and Songfang Brigade Agricultural Science Team of Songzhuang Brigade of our company. A total of 20 plots to spray water as a control, the total test area of 5 acres, before the field conducted a test, after receiving the indoor test species. Experimental field is set in the field in the field, repeated twice, soil, goods
