土壤是农业的基础。一切生物产品都直接或间接地来自土壤。而对农作物来说,土壤更是不可代替的基地。各项农业技术,诸如良种、密植、肥料、水利、农机等都要通过土壤而起作用,许多病虫害也与土壤因素密切相关。没有良好的土壤条件,就没有高产、稳产、优质、低成本的农、林、牧产品,农业翻番就没有稳固的基础。因此,大力改良土壤实为发展农业的一项根本措施。 Soil is the foundation of agriculture. All biological products come directly or indirectly from the soil. For crops, soil is an irreplaceable base. Various agricultural technologies, such as seeds, dense planting, fertilizers, water conservancy and agricultural machinery all work through the soil, and many pests and diseases are also closely related to soil factors. Without good soil conditions, there will be no solid foundation for agriculture, forestry and animal husbandry that yields high yields, stable yields, high quality and low costs and doubled agriculture. Therefore, vigorously improving the soil is actually a fundamental measure for the development of agriculture.
