众所周知,钾对提高作物产量、增强抗性、改善品质等方面有着重要的作用,而作物钾素营养取决于土壤供钾能力和钾肥施用水平。因此,搞清楚我省土壤供钾和钾肥施用状况,不仅对合理施用钾肥,而且对预测钾肥的施用前景都具有重要意义。本文在进行广泛调查和收集土壤测试结果的基础上,对此提出我们的看法,以供参考。 一、我省主要土壤类型和钾素状况 It is well-known that potassium plays an important role in improving crop yield, enhancing resistance and improving quality. The crop potassium nutrition depends on the ability of potassium supply in the soil and the level of potassium application. Therefore, to clarify the status of soil potassium supply and potassium fertilizer application in our province is of great significance not only for the rational application of potash fertilizer, but also for the prospect of potash application. Based on extensive investigations and collection of soil test results, this article presents our views for reference. First, the main types of soil and potassium in our province
