摘 要: | 针对长治市耕地土壤速效钾逐年下降和优质高产谷子需钾较多、土壤供钾不足的现状,进行了对谷子多点施用钾肥的试验、示范、推广。结果证明,在施用氮、磷肥的基础上,每公顷增施钾肥75~300kg,可使谷子增产477~774kg,增产率达15.68%~25.46%。

Effect of Potassium Fertilizer on Millet Development and Yield |
| |
Abstract: | In order to solve the problems of the yearly falling of fast potassium in soil and to meet the needs of fine quality and high yield millet production,an experiment of increasing potassium on many spots proved that on the basis of using nitrogen and phosphorus,an increase of 75~300kg potassium rised yield 15.68%~25.46%,477~744kg/hm2. |
