[0007] Experimental Example of Seedling Cultivation Method of Fast-growing and Early-bearing Pinus koraiensis

[0008] Ten years ago, the branches of Korean pine with female cones were grafted with the branches of Chinese pine seedlings. After surviving, they grew for one year and transplanted to the mountain to grow naturally. After 6 years, 3-4 pine cones will be formed, and the height will be about 5 meters after 10 years. , about 10 centimeters in diameter, and bear fruit 3 times, with an average annual growth of 50 centimeters, and it is growing well now. If carefully managed and fertilized more, the growth will be better.

Abstract

The invention relates to a plant grafting method, in particular to a fast-growing and early fruit bearing seedling raising method for a Pinus koraiensis Sieb.et Zucc., which is realized in such a way that branches of the Pinus koraiensis Sieb.et Zucc. with female cones are grafted on seedling branches of a Pinus tabulaeformis Carr. The seedling of the grafted Pinus tabulaeformis Carr. is transplanted on the hill one year after survival, can grow 50 centimeters tall per year on average and can bear 3-4 fruits after being planted for 6 years under natural growth without fine management. By grafting branches of the Pinus koraiensis Sieb.et Zucc. on the seedling of the Pinus tabulaeformis Carr., the practice shows that the grafted seedling grows faster than the naturally planted Pinus koraiensis Sieb.et Zucc. seedling, has early fruit bearing time, short cycle and low requirement on geologic conditions, is widely planted and inevitably brings good economic benefits with respect to fruit and wood.

Description

technical field [0001] The invention relates to a plant grafting method, namely a fast-growing and early-fruiting seedling raising method of Korean pine. Background technique [0002] Red pine (Pinuskoraiensis Sieb. et Zucc.) is a valuable and rare economic tree species. In my country, it is only distributed in the Changbai Mountains in the northeast to the Xiaoxingan Mountains, and in foreign countries it is only distributed in parts of Japan, North Korea and Russia. Usually, the early growth rate of Korean pine is slow, and it can only grow a few centimeters per year. It takes more than ten years to grow to a height of more than 1 meter. It cannot achieve the purpose of growing fruit and obtaining materials. Korean pine fruit - pine nuts and wood are very popular among consumers, but the price is relatively high and resources are limited. Chinese pine (Pinustabulaeformis Carr.) has a wide range of natural distribution, fast growth, low requirements on the growth environme...
