聚焦三农苏北土壤高沙化日趋严重让人担忧2005年3月中旬,中国科学院南京土壤研究所王强教授对苏北地区的盐城、泰州、扬州、淮安等地土壤现状进行调查、测试,“中科视窗”的新闻工作者随同进行了采访。记者:王教授,请您将四个市的土壤结构调研和测试结果做个评介,好吗?王教授:东台以北,204国道以东,土壤沙化现象严重;204国道以西,运河以东,土壤处于中等地力现状;从测试结果来看,金湖县的土地地力处于中上等,有机质的含量一般保持在1.8-3.5以上。记者:土壤高沙化将给农民带来什么样的后果?王教授:农民用肥越来越多,而农田的粮食产量将会越来越低,如此下去可导致农田颗粒无收。记者:针对土地高沙化现状,我们怎样来扼制这一势态的发展?王教授:这是一项艰巨而有宏大的工程。一方面政府要坚定不移地搞好水网化建设,要加大植树造林的力度;要做好水土保持工作;要做好宣传和引导工作;要制订切实可行的措施。另一方面呢,做为农民兄弟而言,要多施有机肥或有机无机复合肥,摒弃过去那种拼命向土地施过量的无机肥,造成地力下降,土壤团力结构破坏的陈旧观念,要做到科学种田,平衡施肥。唯其如此,才能为我们的子孙后代留下一片蓝天绿地。记者:感谢您能抽出宝贵时间接受采访,再见!王教授:再见!
Focusing on agriculture, rural areas and farmers in northern Jiangsu High-desertification becomes more and more worrying In mid-March 2005, Professor Wang Qiang from Nanjing Institute of Soil Science, Chinese Academy of Sciences investigated and tested soil status in Yancheng, Taizhou, Yangzhou and Huai’an, Zhong Ke window "journalists along with the interview. Reporter: Professor Wang, please refer to the soil structure research and test results of four cities, please? Professor Wang: To the north of Dongtai and to the east of State Road 204, soil desertification is serious. To the west of State Road 204, to the east of the canal, Soil is in the middle of the status of the soil; from the test results, Jinhu County, land fertility in the upper, the organic matter content generally maintained at 1.8-3.5 above. Reporter: Soils soil high desertification will give farmers what kind of consequences? Professor Wang: Farmers use more and more fertilizer, and farmland food production will be getting lower and lower, so go down can lead to crop failure. Reporter: In response to the status quo of land desertification, how can we curb the development of this trend? Professor Wang: This is a difficult and ambitious project. On the one hand, the government should unswervingly improve the construction of water networks and intensify the efforts of tree planting and afforestation; do a good job in water and soil conservation work; make propaganda and guidance work; and formulate practical measures. On the other hand, as peasant brothers, we should give more organic fertilizer or organic-inorganic compound fertilizer and abandon the old idea of destroying inorganic fertilizers desperately applied to the land, destroying soil fertility and destroying the soil mass structure. Achieve scientific farming, balanced fertilization. Only in this way can we leave a blue sky and green space for our children and grandchildren. Reporter: Thank you for taking the time to interview, bye! Professor Wang: Goodbye!
