随着农业生产上氮磷化肥施用量的增加,钾肥的需要也逐渐突出.近年来,我省结合水泥生产,生产了一些窑灰钾肥,1974年在各地进行了窑灰钾肥多点试验.现将结果整理如下:一、窑灰钾肥的增产效果试验结果表明:在许多土壤上施用窑灰钾肥对多种作物都有明显增产效果.据初步统计,在镇江、扬州、苏州地区的丘陵板浆白土、白土、黄白土、黄泥土、黄粘土;太湖沿岸酸性较强的草渣土、平原白土;沿江两岸的高沙土、夹沙土、夹沙乌山土;南京地区的马肝土、青泥条等类型土壤上施用窑灰钾肥,增产效果明显.此外,在徐淮地区的沙土、沙壤土上(盆栽试验)施用,也有增产作用. With the increase of the amount of nitrogen and phosphorus fertilizers applied in agriculture, the demand of potash fertilizer has also gradually become prominent. In recent years, some kiln-lime potash fertilizers have been produced in our province in combination with cement production. The results are summarized as follows: First, the kiln-lime potash fertilizer production test results show that: in many soil application of Kiln and lime fertilizer on a variety of crops have a significant increase in production.According to preliminary statistics, in Zhenjiang, Yangzhou, Suzhou, White clay, white clay, yellow clay, yellow clay, yellow clay; along the coast of Taihu Lake acidic acid grass residue, plain white clay; high sand along the banks of the earth, sandy soil, sandy sand sand; Nanjing Ma liver soil, And other types of soil application of Kiln and Potash Fertilizer, yield increase effect is obvious.In addition, in Xuhuai area of ​​sand, sandy loam soil (pot experiment) application, but also increase yield.
