水、气、热是与土壤肥力密切相关的三要素,只有三者充分协调,土壤肥才能得到充分发挥,作物生长才有可靠的基础。调解土壤水、气、热的主要措施是: 一、加强农田基本建设。对农田要做到精耕细作,加深活土层,增加有机质,改良土壤,提高土壤肥力。为此,必须因地制宜,坚持不懈的大搞农田基本建设。具体讲,山区、丘陵地,由于坡陡,径流量大,水土流失严重,因此要以改
Water, gas and heat are three elements that are closely related to soil fertility. Only when the three are fully coordinated can soil fertilizers be fully utilized and crop growth has a reliable foundation. The main measures to mediate soil water, gas and heat are: First, to strengthen farmland capital construction. To farmland to be intensive, to deepen the living soil, increase organic matter, improve the soil, improve soil fertility. To this end, we must, according to local conditions, unremittingly engage in farmland capital construction. Specifically, mountainous areas and hilly areas, due to steep slopes, heavy runoff and serious soil erosion,
