一、主要作物吸收氮磷钾的数量作物生长的好坏和产量的高低,主要靠路线、靠干劲、靠“八字宪法”的综合运用。土是基础,水是命脉,肥料是植物的粮食。作物生长在土壤上,从土壤中吸收各种养分。土壤的水、肥、气、热等理化生物性状,耕性结构,生产性能和养分供应能力,直接关系到作物的生长发育和产量水平。通过施肥,不断地补充、调节和增强土壤养分供应能力,是获得
First, the main crops to absorb the amount of NPK Potential growth and yield of crops and the level of production, mainly by route, by motivation, by the “Eight Character Constitution” comprehensive utilization. Soil is the foundation, water is the lifeblood, and fertilizer is the plant’s food. Crops grow on the soil, absorbing various nutrients from the soil. Soil physical and chemical properties such as water, fertilizer, gas, heat and so on, tillage structure, production performance and nutrient supply ability are directly related to crop growth and yield. Through fertilization, continuous replenishment, regulation and enhancement of soil nutrient supply capacity are obtained
