Description

Arbor transplanting method

Technical Field

The invention relates to the technical field of arbor transplanting.

Background

Sandy soil is generally difficult to be directly applied to seedling cultivation, particularly when trees such as arbors have tall trees and developed root systems, the sandy soil is difficult to maintain stable and healthy growth and development. However, trees are main tree species in gardens due to the characteristics of dense crowns, tall and straight bodies, strong vitality and the like, transplanting requirements are met in many places, a lot of sandy soil sites particularly hope to improve and beautify the environment through arbor transplanting, and the survival rate of the trees transplanted to the sandy soil in the prior art is extremely low.

Therefore, in part of the technologies, improvement of sandy soil is considered, for example, a aeolian sandy soil modifier is proposed in Chinese patent CN201010167195.0, and the modifier is prepared from cow dung, corn straw, furfural residue, sheep dung and CO (NH)₂)₂、NH₄H₂PO₄Mixing, fermenting to form, can play certain improvement effect to wind sand, effectively improved the water conservation of wind sand, protect fertile ability, but it mainly concentrates on adding nutrient composition to soil, do not play the effect of improving to the loose texture of soil, even make soil after adding nutrient substance, the fertility still can run off fast, be difficult to maintain, too much nutrient composition supply simultaneously, also cause harmful effects to the nursery stock of cultivating itself easily, in addition, nursery stock root system and huskyThe soil is loosely combined, so that the transplanting is difficult.

In a thesis of 'improvement test research of dredger fill sea sand soil in Qidong area' ('construction technology', 11 months 2014), well known people and the like research the improvement of the dredger fill sea sand soil through inorganic binders, and find that the shear strength of the dredger fill sea sand soil can be effectively improved, the plasticity of the dredger fill sea sand soil can be reduced, and the engineering performance of the dredger fill sea sand soil can be improved by adopting certain inorganic materials, such as lime and the like; however, the method for improving sandy soil by using inorganic materials usually has too strong consolidation force on soil particles, is difficult to apply to agriculture and forestry cultivation, and when the sandy soil improved by using inorganic binders is used for seedling cultivation, seedlings usually die quickly.
