种田要好土,养儿要好祖农业生产要求在不断提高劳动生产率的基础上,得到稳定高产,而肥沃的土壤則是达到这种理想的重要物质基础。我們知道,在植物的生活条件中,除了日光和热来自宇宙外,其余的养料、水分和一部分空气,都是取之于土壤的。在一个不良的土壤中,这些因素不能够充足而經常地滿足植物的需要,在很大的程度上依賴于自然的調节(如气溫、降雨)和人为的調节(如施肥、灌溉排水、耕作等)。但是由于气
Farming is better for soil and raising children. Good Agricultural production requires steady and high yield on the basis of continuous improvement of labor productivity. Fertile soil is an important material basis for achieving this ideal. We know that in the living conditions of plants, except the sunlight and heat from the universe, the rest of the nutrients, moisture and some of the air are taken from the soil. In a poor soil, these factors do not adequately and frequently meet the needs of plants and depend largely on natural adjustments (such as air temperature and rainfall) and man-made adjustments (such as fertilization, irrigation and drainage , Farming, etc.). But due to gas
