Method for planting fraxinus chinensis in saline-alkaline land using containers for alkaline insulation

Abstract

The invention discloses a method for planting fraxinus chinensis in saline-alkaline land using containers for alkaline insulation. The method includes the following steps that 1, planting baskets are made, each planting basket includes an inner frame and an outer frame, the inner frame is arranged in the outer frame, the inner frame and the outer frame are fixedly connected into a whole, wire meshes are fixed on the four sides and bottom face of the inner frame and the four sides and bottom face of the outer frame, and reed is placed in four-side interlayers and a bottom interlayer between the inner frame and the outer frame; 2, suitable saplings are selected; 3, an excavator is adopted to dig holes, removed saline-alkaline soil is transported to the outside of a field, and the sizes of the holes are greater than those of the planting baskets; 4, the planting baskets are placed into the holes, the selected saplings are planted into the planting baskets, fertile and ripened soil which is used for cultivation many years is adopted to bury the saplings and then trodden to be compact, and the saplings are watered thoroughly. By the adoption of the method for planting fraxinus chinensis in the saline-alkaline land, the purposes are achieved that the survival rate of the year reaches 100%, the saplings grow vigorously and a forest is formed rapidly, the forest form is equal in size, and the beautifying and greening effects are ensured.

Description

technical field [0001] The invention relates to the technical field of tree planting in saline-alkali land, in particular to a method for planting ash trees in saline-alkali land by using containers to isolate alkali, which is applied to heavy saline-alkali land with a salt content of more than 0.6%. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares, if such a large area of ​​saline-alkali land can be utilized, it will have important market value and social value, so the development of saline-alkali land planting technology is extremely critical. [0003] For many years, the tree planting on the heavy saline-alkali land in most areas has caused the phenomenon that no trees are...

Problems solved by technology

[0003] For many years, the tree planting on the heavy saline-alkali land in most areas has caused the phenomenon that no trees are planted every year. The survival rate of trees is extremely low, which wastes a lot of manpower, material and financial resources. In some areas, it is difficult to achieve greening effect for many years. Planting every year and replenishing every year, the size of the forest is uneven, which seriously affects the beautification and greening effect. It is particularly important to invent a planting method that can improve the survival rate of planting and ensure one-time forest formation.
