农业生产措施的大大改变,尤其是随着产量的大幅度提高,使投入到农田中的肥料等物质逐年增多,土壤环境也在悄悄地发生着变化。根据普查土壤样品的检测数据,发现土壤中的养分含量状况发生了很大变化,并且不同地块土壤的各种养分含量值的差异也在变化。通过对大洼县土壤养分水平的分析,提出科学的施肥依据。
Significant changes in agricultural production measures, especially with a substantial increase in production, so that inputs into the farmland of fertilizers and other substances increased year by year, the soil environment is also quietly changing. According to the survey data of the census soil samples, it was found that the nutrient content in the soil has undergone great changes, and the differences of various nutrient content values in the soil of different plots have also changed.
