肥料是农业生产的一项重要内容。它的作用主要是促进土壤团粒结构的形成,使土壤中空气和水的比值协调,使土壤疏松,增加保水、保温、透气、保肥的能力;全面供应作物生长所需的养分;减少养分固定,提高肥效;减少流失,改善作物对养分的吸收条件;调节土壤酸碱性,改良土壤结构。
Fertilizer is an important part of agricultural production. Its main role is to promote the formation of soil aggregate structure, so that the ratio of air and water soil coordination, the loose soil, increase water retention, heat, breathable, fat-saving capacity; the full supply of nutrients needed for crop growth; reduce nutrient fixation , Improve fertilizer efficiency; reduce loss, improve crop nutrient absorption conditions; regulate soil acid-base, soil structure improvement.
