Application of earthworm faeces, compost or earthworm faeces-compost leaching liquor soaked seeds in lawn plant

Abstract

The invention discloses the applications of earthworm cast, dunghill, and mixing leaching liquor soaking seeds of the earthworm cast and the dunghill in the aspect of improving the early-stage growing vitality of a lawn plant which improves the early-stage growing vitality of the lawn plant through 3 methods of soaking seeds by water extract; thereby reaching the target of improving excellent lawn building at the early-stage of the lawn. A test result shows that the earthworm cast, the dunghill, and the mixing leaching liquor soaking seeds of the earthworm cast and the dunghill can improve the seed bourgeon rate of the lawn plant and the leaching liquor with a certain proportion has remarkable promoting effects on increasing the biomass on a land of ryegrass and tall fescue; wherein, the effect of the earthworm cast is the most remarkable; meanwhile, the water extract also increases the chlorophyll content of the plant, promotes the photosynthesis and growth of the plant and improves the capacity of the lawn plant to compete with weeds; thereby reaching the target of improving the excellent lawn building at the early-stage of the lawn.
