长期以来,人们认为甘薯施用氯化铵、氯化钾等含氯化肥后,不仅会使淀粉含量降低,而且薯块不耐储藏,致使这类化肥的施用受到了限制。为明确含氯化肥在甘薯上的实际效果,以便明确其施用价值,我们进行了两年的田间和室内试验。现将结果整理如下。 For a long time, people think that the use of ammonium chloride, potassium chloride and other chlorine-containing fertilizers, not only will reduce the starch content, and the tubers intolerance of storage, resulting in the application of such fertilizers have been limited. In order to clarify the actual effect of chlorinated fertilizers on sweet potatoes in order to clarify their application value, we conducted two years of field and laboratory experiments. The results are now organized as follows.
