Problems solved by technology

However, this method is time-consuming and labor-intensive, and the cost of manual excavation, transportation and handling is extremely high, but the effect of root system restoration is often unsatisfactory. The rate of dead branches in the late stage of magnolia plants is relatively large, and the plant landscape effect is poor.

Embodiment 1

[0031] According to this method, 56 Lechang Michelia seedlings with a DBH of 20 cm were transplanted in Hangzhou City, Zhejiang Province in spring. The soil at the excavation site of Lechang Michelia was sandy loam. Digging to 25cm place, its first layer of lateral roots is all dug out, its lower main root and other lateral roots are shoveled off, and the soil on its root system is knocked out to obtain the bare root seedling of Lechang Michelia. After the Lechang Michelia was transported to the transplanting site, it was pruned, with 2 / 3 branches thinned and 4 / 5 leaves removed; planting management was carried out according to other steps of this method. One year after planting, 55 Lechang Michelia trees survived, with a survival rate of 98.2%, and the rate of dead branches of the surviving Lechang Michelia chinensis was 0. The survival rate of ordinary transplanted Lechang Michelia seedlings is less than 60%, and the rate of dead branches after survival is more than 30%. Ado...

Embodiment 2

[0033] Transplant 87 Liriodendron seedlings with a DBH of 15cm in autumn according to this method in Hangzhou City, Zhejiang Province. The soil at the excavation site of Liriodendron is sandy loam. Dig out its first layer of lateral roots to 30cm place, shovel off its lower main root and other lateral roots, knock out the soil on its root system, and obtain the bare-rooted tulip tree seedlings. After the Liriodendron is transported to the transplanting point, it is pruned, the amount of thinning is 2 / 3, and all the leaves are removed; planting management is carried out according to other steps of this method. One year after planting, 85 Liriodendron trees survived, with a survival rate of 97.7%, and the rate of dead branches of the surviving Liriodendron was less than 5%. Liriodendron tulipifera seedlings generally have a survival rate of less than 55% after transplanting, and a dead branch rate of more than 30% after survival. The adoption of the method greatly improves the ...

Abstract

The invention provides a method for bare root transplantation by expanding magnoliaceae plant fibrous root reserving range. During excavation, a shovel and the like are utilized to perform excavation outwards and downwards gradually along a magnoliaceae trunk; and when excavation is performed to lateral roots, excavation is performed in the lateral root extending direction until a first layer of lateral roots is all exposed. Redundant soil on the lateral roots is removed, only soil on the original growth site of the seedlings is reserved, and it is guaranteed that fibrous root systems on the lateral roots are complete. The method has the advantages of having convenience in transportation and being simple to operate, high in survival rate and good in later period landscape effect and the like.

Description

technical field [0001] The invention belongs to the field of landscaping, in particular to a method for improving the survival rate of magnoliaceae seedlings after transplanting. Background technique [0002] Magnoliaceae plants have the characteristics of bright colors and pleasant fragrances, and are widely used in gardens, parks, roads and other garden landscapes. However, the root system of Magnoliaceae is a fleshy root, and improper handling during transplanting is likely to cause slow recovery of the root system, or even rotten roots, resulting in a low survival rate for transplanting large seedlings of Magnoliaceae. [0003] At present, the transplanting of large seedlings of Magnoliaceae plants usually increases the survival rate by enlarging the diameter of the soil ball. The existing technology often uses the trunk as the center and draws a circle with a diameter 6-10 times the diameter at breast height. The circle is the soil ball. Boundary, dig vertically down a...
