摘要: The invention discloses a high-temperature insect killing and sterilization treatment method for soil. comprises the following steps that A, straight ditch is dug in crop planting land, out-dug soil stacked at two sides of separately; B, soft heating pipe laid direction ditch, venting holes are uniformly distributed an array mode; C, backfilled with sides; D, surface covered transparent thin film; E, high-pressure hot steam introduced into to conduct on backfill ditch; F, after finished, drawn back, film removed, pests cleaned away. Chineseyams pretreated modes digging laying pipe, bacteria harmful crops killed; meanwhile, plowing, airing other linksof land before planted simplified, efficiency Chinese yam seedlings improved, survival rate increased.
