Yulan cultivation method

Abstract

The invention relates to a yulan cultivation method, pertaining to the technical field of woody plant cultivation. The technical problem is solved by providing the cost-effective yulan cultivation method. The yulan cultivation method comprises following steps of: a, selecting seeds; b, cultivating seedlings; c, planting seedlings: selecting plants at the seedling age of 1.5 to 3 years and height of 0.5 to 1.0m as seedlings, digging holes at depths of 45-55cm at intervals of 1.5 to 2m*2.0 to 2.5m and cultivating one plant in each hole; d, performing intermediate cutting: performing intermediate cutting and harvesting on forests after 8 to 10 years and adopting a one-spacing one-cutting form; sprouting multiple branches of new seedlings out of stumps after harvest and adopting the method of removing sprouts year by year, keeping 3-4 branches of stump plants / stump in the first year, removing sprouts to 1-2 branches / stump in the second year and finally keeping one new seedling in the third year; and e, replacing old-growth forests: utilizing cuttage or cultivated new seedlings to replace stumps of lower replacement and reproduction capabilities or grating young shoots of yulan by adoption of stumps of low capabilities as stock.

Description

technical field [0001] The invention relates to a cultivation method of magnolia, belonging to the technical field of woody plant cultivation. Background technique [0002] Magnolia officinalis (Magnolia officinalis) is a precious woody Chinese medicinal material and a rare plant unique to my country, belonging to the Magnoliaceae. For a long time, the medicinal magnolia has mainly used wild resources. Due to the increasing demand and the decreasing wild resources, it has been listed as a national second-class protected Chinese herbal medicine. Since the 1990s, although a large number of magnolia plantations have been carried out, there are not many magnolia forests with good stand quality. Due to the lack of scientific guidance in artificial planting planning, and with the thinning and harvesting of magnolia resources, the impact of diseases and insect pests, or the induction of natural factors (mainly referring to climate), the structure and stability of magnolia forests ...

AI Technical Summary

Problems solved by technology

Since the 1990s, although a large number of magnolia plantations have been carried out, there are not many magnolia forests with good stand quality.

[0003] In the past, there was a lack of in-depth research and effective methods for the transformation of magnolia low-efficiency forests, mainly through enclosure protection, allowing its natural growth and regeneration, or carrying out full-scale or high-intensity clearcutting and then carrying out artificial afforestation.

The above method has many disadvantages in the practical implementation, such as long time-consuming, low efficiency, low survival rate of afforestation due to soil erosion, and slow growth of magnolia seedlings, etc., resulting in unsatisfactory transformation effect of magnolia forest. However, no better method has been proposed for the maintenance of the felled secondary forest. Therefore, generally speaking, the economic benefits of its magnolia forest are still not high.
