Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, highlands planting tree is cheated, and comprises hole body 1 and is positioned at the planting soil of cheating body 1 inside; The inner surface of described hole body 1 is provided with one deck mud off 11.Mud off 11 is between the inner surface and planting soil of hole body 1, and thickness is preferably 5 ~ 8cm, makes mud off 11 both have good insulating effect like this, is convenient to again penetrating of tree root.Mud off 11 is made up of mud, the semifluid that described mud mixes primarily of water, clay and curing agent, and it has serum denseness; During making, can by mud by smearing, the mode such as grouting is arranged on the inner surface of hole body 1; Wherein, curing agent has another name called curing agent, curing agent or set agent, is that a class is promoted or controls material or the mixture of curing reaction.In the early stage of arboreal growth, mud off 11 can reduce the loss of moisture and fertility in the body 1 of hole; In the intermediary and later stages of arboreal growth, mud off 11 basic with planting soil with cheat the outer soil of body 1 and combine together, the root system of trees can penetrate mud off 11 continued growth, has good facilitation to the growth of trees, and can not to environment; And mud off 11 itself still has certain seepage of water, when cheating hypervolia in body 1, unnecessary water can ooze out from mud off 11.
In order to make the mud off 11 made have best effect, selecting sticky content to be not less than 30%, clay that plasticity index is not less than 25 prepares mud; The mud of grouting is 1.45 ~ 1.7 relative to the proportion of water, and in mud, the weight proportion of clay and curing agent is 10:1.According to GB/T501231999 " Standard for test methods of earthworks " regulation, the content that particle diameter is less than 0.005mm soil particle is sticky content.Plasticity characterizes fine grained soil physical property key character, generally represents by plasticity index; Plasticity index to a certain extent concentrated expression affects the various key factors of cohesive soil feature; Plasticity index is larger, and show that the particle of soil is thinner, specific surface area is larger, and glutinous grain or hydrophilic mineral (as the montmorillonite) content of soil are higher, and the change of moisture content scope that soil is in plastic state is just larger.
In order to improve the survival rate that sapling 8 is planted in highlands, simultaneously in order to ensure the growing way in sapling 8 later stage, we are provided with the hole body 1 of specific standard for the sapling 8 of dissimilar, different size; The size of concrete arbor class and flowering shrub class sapling 8 and the corresponding relation of hole body 1 specification are as following table:
