窑灰钾肥是水泥工业大搞综合利用的一种副产品。根据广东东莞水泥厂介绍,它一般含有氧化钾7～11%、氧化钙20～30%、氧化镁0.5～1%。“肥料是庄稼的粮食,肥料不能满足大幅度增产的需要,是当前农业生产上一个极为尖锐的问题”。考虑到钾肥对甘蔗生长的重要性,为了探求各种可供本省蔗区应用的钾肥来源,以适应增产甘蔗,发展糖业生产的需要,一年多来我们在进行甘蔗施用钾镁肥(盐场副产品)表证的同时,开始进行甘蔗施用窑灰钾肥的研究。在有关方面的大力支持和蔗区群众的
Kiln gray potash is a by-product of the comprehensive utilization of the cement industry. According to Dongguan, Guangdong Cement Plant, it generally contains 7-11% of potassium oxide, 20-30% of calcium oxide, 0.5-1% of magnesium oxide. “Fertilizer is the grain of crops, the fertilizer can not meet the need for a substantial increase in production, is an extremely acute problem in agricultural production ”. In view of the importance of potash on the growth of sugarcane, in order to explore all kinds of potash sources that can be used in this province’s sugarcane area to meet the need of increasing sugar cane production and developing sugar production, we have been using potassium and magnesium fertilizer for sugar cane for more than a year By-product) form of certificate at the same time, start the application of sugarcane kiln dust potash research. Strong support in relevant areas and people in the sugarcane area
