在渭北旱塬澄城县自然气候条件下，用高效沼气池的沼液对旱地小麦进行了浸种试验。结果表明，沼液浸种能促进旱地小麦的发芽势，提高出苗率２５．０％，根系发育与对照相比差异极显著，次生根数和根长分别比对照提高１１．６５％和１４９．１６％，根系生物量和茎叶生物量分别比对照增加１７５％和３３．３％，苗壮根多，为旱地小麦丰产奠定了基础
Under the natural climatic conditions of Chengcheng County in Weibei Arid Highland, the soaking liquid of dry land wheat was tested with biogas slurry of high-efficiency biogas digester. The results showed that soaking biogas slurry could promote the germination potential of dryland wheat and increase germination rate by 25.0%. The root development was significantly different from that of the control. The number of secondary roots and root length increased by 11.65% and 149.16, respectively %, Root biomass and stem and leaf biomass increased by 175% and 33.3% respectively compared with the control, with strong seedlings and strong roots, which laid the foundation for the high yield of dryland wheat
