耕地质量如何,事关粮食产出能力,耕地质量一直受国家农业局高度关注。日前,农业部发布了《2016年全国耕地质量监测报告》。报告表明,我国耕地质量呈现三大特点,土壤结构性问题比较明显,土壤养分含量稳中有升,土壤健康状态总体良好。监测数据显示,我国耕地土壤结构性问题主要表现为耕层变浅,板结问题较为突出。全国有65.5%的监测点耕层厚度较浅,其中上海、江苏、广东等省(市)耕层平均厚度低于18 cm,而适宜作物生长的耕层厚度在20 cm以上。有25.9%的监 How the quality of arable land is related to the ability of grain output, the quality of arable land has always been highly concerned by the State Bureau of Agriculture. Recently, the Ministry of Agriculture released the 2016 National Cultivated Land Quality Monitoring Report. The report shows that the quality of cultivated land in China presents three major characteristics, the soil structural problems are obvious, the soil nutrient content is steadily rising, and the soil health status is generally good. Monitoring data show that the structural problems of cultivated land in China are mainly characterized by shallowing of plow layer and more prominent plate knotting problems. There are 65.5% of the monitoring points in the country where the thickness of the tillage pits is shallow, of which the average tillage thickness of the provinces (cities) in Shanghai, Jiangsu and Guangdong is less than 18 cm, while the tillage thickness suitable for crop growth is more than 20 cm. There are 25.9% of supervisors
