农业生产的发展和氮肥施用量的提高,突出反映了钾肥在农作物增产作用的显著性和需求量。目前,我省钾肥来源不足,多由国外、省外调进,如能开发利用我省钾矿资源,具有相当重要的意义,并已引起人们的极大关注。针对我省利用钾矿粉的情况,我们测试了不同浓度的硫酸对钾矿粉节钾素的提取率和钾细菌转化钾矿粉中钾素能力。试验为开发利用钾矿资源提供了参考数据。
The development of agricultural production and the improvement of the amount of nitrogen fertilizer application have prominently reflected the significance and demand of potash fertilizer in increasing crop yield. At present, the shortage of potash fertilizer in our province is mostly caused by the fact that potash resources in our province can be exploited and utilized by other provinces and foreign countries. This has great significance and has drawn great attention from people. In the light of the utilization of potash ore in our province, we tested the extraction rate of potassium by different concentrations of sulfuric acid and the potassium conversion efficiency of potassium by potassium bacteria. The experiment provided reference data for the exploitation and utilization of potash resources.
