耕地土壤肥力的高低,关键看土壤库的供给能力。所谓土壤库,就是耕地土壤内含有的养分总合及其协调性能。耕地土壤肥力高,扩大再生产的能力就强,而耕地土壤肥力低,生产能力就降低,这样会影响到农产品的提供数量与质量,也阻碍农业现代化的发展速度。为此,我们对嫩江地区及齐齐哈尔市郊主要耕地土壤肥力的演变规律,进行了系统的调查。通过土壤速测与常规分析,及田间诊断试验,观察土壤生产率的高低和抗灾能
Soil fertility level of cultivated land, the key to see the supply capacity of soil bank. The so-called soil bank, is the soil nutrients contained in the farm and its coordination of performance. The soil fertility of cultivated land is high, and its ability to expand reproduction is strong. However, the fertility of cultivated land is low and its productivity is reduced. This will affect the quantity and quality of agricultural products and hinder the development of agricultural modernization. To this end, we conducted a systematic investigation of the evolution of soil fertility in main cultivated land in the Nenjiang area and the suburb of Qiqihar. Through soil testing and routine analysis, and field diagnostic tests to observe the level of soil productivity and resilience
