and (5) establishing a slurry pool and mixing the slurry. This scheme design has characteristics such as construction convenience is swift, with low costs and practicality are strong.
In the scheme, in order to realize other functions of the prepared slurry, such as adding plant nutrients to the trees or adsorbing redundant moisture to the trees so as to ensure the humidity of soil layers around the trees, the prepared slurry is required to be improved; correspondingly, before the prepared mud is injected into the soil layer along the periphery of the arbor, the method further comprises the following steps:
additives are incorporated into the prepared mud to form a modified mud.
Specifically, in order to achieve the above object, accordingly, the additive comprises: resin and lime soil. The resin can be used for adsorbing redundant moisture in a soil layer around the arbor so as to ensure that the soil layer around the arbor is maintained at proper humidity; in addition, the lime soil can be used to provide plant nutrients to the surrounding soil layers of the trees to further benefit the growth of the trees.
Further, the mass ratio of the prepared slurry to the resin to the soil ash is 600: 1: 2.5. the scheme is designed like this, and has the characteristics of good anti-liquefaction effect, low cost and the like.
Still further, in order to improve the water absorption of the resin and reduce the soaking of the water body on the root of the arbor, correspondingly, the resin is super water-absorbent resin.
