土壤机械化深松就是利用耕作机械疏松土壤,加深耕作层。它是适合现代农业的保护性耕作技术之一。一、土壤机械化深松的好处1、打破犁底层。家庭承包土地,多用中小型机械旋耕或翻耕作业,耕作层较浅,年复一年,一般在15厘米以下的土壤中形成犁底层,板结、坚硬、通透性差,影响作物根系下扎。而机械化深松后,耕深可达20—30厘米以下,消除犁底层,为作物生长提供疏松深厚的土层。 Soil mechanization deep loose is the use of farming machinery loose soil, deepen farming layer. It is one of the conservation tillage technologies suitable for modern agriculture. First, the benefits of soil mechanization deep loose 1, to break the plow bottom. Family contract land, use small and medium-sized mechanical rotary plowing or tillage operations, farming layer shallow, year after year, generally below 15 cm in the soil to form plow the bottom, hardened, poor permeability, affecting crop root bar . And mechanized subsoiling, deep plowing up to 20-30 cm below the elimination of the plow bottom, providing a loose soil for crop growth.
