吴江市耕地面积减少,后备资源不足。通过地力调查,寻求稳总产的新途径。调查结果表明:当地土壤的自然肥力性状退化,作物抗逆性减弱,严重缺钾;农田基础设施差,障碍层位高,土体结构差。由此提出改良土壤、改造低产田的对策,以提高土壤的肥力,稳定粮食总产。
Wujiang City, reduced arable land, lack of reserve resources. Through the investigation of geotechnical force, seek a new way to stabilize the total output. The results showed that the natural fertility traits of local soils degenerated, the stress resistance of crops weakened and the potassium deficiency was serious. The farmland infrastructures were poor, the level of obstacle beds was high and the soil structure was poor. Therefore, the countermeasures to improve the soil and transform low-yielding fields are put forward so as to increase soil fertility and stabilize the total output of grain.
