Northeast Chinese yew transplanting method in coast saline-alkaline region

Abstract

The invention relates to a northeast Chinese yew transplanting method in a coast saline-alkaline region. The method comprises the steps of 1) selecting a place that has a shade and a high physical feature where hydrocele is difficult from the middle ten days of March to the middle ten days of April; 2) digging a tree aperture according to the soil ball size of a transplanted nursery stock; 3) mixing well raw soil dug from the tree aperture with turfy soil and river sand in volume ratio of 1:1:1 to obtain plantation soil; 4) filling part backfilling soil, putting the soil ball of the transplanted nursery stock to guarantee that the rhizome junction of the plant is 10cm higher than the ground, then filling the backfilling soil, stamping and compressing; 5) using an aqueous solution that containing 0.3mmp Naphthalene acetic acid, 0.5ppm indole butyric acid and 300ppm calcium nitrate as a root water. <{EN2}>According to the invention, the Chinese yew can be possibly planted in a coast saline-alkaline region, which means a lot for lifting city greening level and landscape effect.

Description

technical field [0001] The invention relates to a transplanting method of the northeast yew, in particular to a transplanting method of the northeast yew in coastal saline-alkali areas. Background technique [0002] Northeast yew (Taxus cuspidata), also known as yew, is a taxus tree plant. It is a precious tree species left over from the Tertiary Period.

[0003] In coastal saline-alkaline areas, the soil salinity can generally reach 0.5-1.0%, pH value > 8.0, and nutrients are poor. At the same time, the groundwater level is high, the degree of mineralization is high, and the natural drainage is not sm...

Problems solved by technology

However, Tianjin Binhai New Area is located in the coastal heavily saline-alkaline area, and greening is difficult. In recent years, through the unremitting efforts of governments at all levels and affiliated enterprises, the urban greening environment has been better improved, and the greening rate has been greatly improved. However, there are still Problems such as simple urban greening structure, single plant community and poor diversity

Northeast yew has a beautiful tree shape and is an excellent urban greening material. However, in the Binhai area of ​​Tianjin, the introduction has repeatedly failed, and there is basically no precedent for successful open-field cultivation.
