现阶段,我国的总耕地面积约为1.22亿hm2,较之1997年的1.30亿hm2,锐减了0.07亿hm2之多,究其根本原因是由于城市化建设进程的加快及工业化不断发展所导致的。为了确保农作物产量不受耕地锐减的影响,必须采取相应的措施改善原有土壤的结构,以此来提高农作物的产量。土壤结构改良剂在改善土壤结构上具有十分明显的效果,基于此点,本文首先对土壤结构改良剂概述,进而分析土壤结构改良剂的改土效果,最后介绍土壤结构改良剂的具体使用方法。
At this stage, China’s total arable land area is about 122 million hm2, a drop of more than 7 million hm2 compared with 1997’s total of 130 million hm2. The root cause is due to the acceleration of urbanization and the continuous development of industrialization of. In order to ensure the crop yield is not affected by the sharp decline of cultivated land, corresponding measures must be taken to improve the structure of the original soil so as to increase the crop yield. Based on this point, this paper first summarizes the soil structure improvers, and then analyzes the soil improvement effect of soil structure improvers, and finally introduces the specific use of soil structure improvers.
