摘要
对轻型铧式犁增设深松装置，可以在耕层以下间隔松土，打破犁底层，获得虚实并存的良好耕层结构。田间试验表明：在不影响原耕层质量的前提下，可以保证在耕层以下松土，深度达５～１５ｃｍ。在耕层以下松土深度１５ｃｍ，单铧松土宽度为１２ｃｍ、１０ｃｍ、６ｃｍ时，牵引阻力分别增加１２．１６％，９．５４％，７．５６％。
Loosen the soil device was designed and installed on the light moldboard plow. It can be used for loosening the plough sole at a distance and creating a good cultivated layer of sallow ploughing and deep loosening. Field tests showed that the depth of the plough was about 20cm, the depth of the loosen the soil beneath the plough layer were 5～15cm, the pl oughing quality was satisfactory,while the depth of loosen soil was 15cm and the width were 12cm. 10cm. 6cm respectively, the pulling force increased by 12.16%. 9.54%.7.56% respectively.
