Problems solved by technology

Since the 1990s, although a large number of Magnolia officinalis artificial forests have been carried out, there are not many Magnolia officinalis forests with good stand quality.
The above methods have certain effects on the cultivation and felling of Magnolia officinalis in the early stage, but no better method has been proposed for the maintenance of the secondary forest after felling. Therefore, generally speaking, the economic benefits of its Magnolia officinalis are still not high

Embodiment

[0033] Embodiment Adopt the method of the present invention to cultivate magnolia officinalis

[0034] Seed selection: Select high-quality Magnolia officinalis species with a tree age of 25 years, tree height > 10m, diameter at breast height > 15cm, and active ingredient content in stem bark > 5.0% in Aba Prefecture, Sichuan Province. For the diseased cattail (Baogu), rub 1% lime water with wet fine sand to remove the wax on the surface of the seeds, and become the seeds to be sown for later use.

[0035] Seedling cultivation: The sowing time is around the beginning of spring. Soak the spare seeds to be sown at 28-30°C for 5 days, and change the water once a day (according to the situation, a certain concentration of germination agent can be added appropriately). Plant the spare seeds in the nursery, the sowing distance is 20cm×15cm, and the wet soil is 1.5-3.0cm, and keep it moderate, and the seedlings will emerge in about a month. The seedlings were watered and weeded in d...

Abstract

The invention relates to a magnolia officinalis cultivation method and belongs to the technical field of woody plant cultivation. The invention solves the technical problem of providing a magnolia officinalis cultivation method which has higher economic benefit. The magnolia officinalis cultivation method comprises the following steps of: a. seed selection; b. seedling cultivation; C. seedling planting: selecting 1.5-2.5-year and 0.8-1.2m-hight plants as saplings, digging 50-60cm-deepth pits with the spacing of (1.8-2.2m)*(2.3-2.8m), and planting one seedling in each pit; d. intermediate cutting: harvesting forest by intermediate cutting in an alternating way after 8-10 years, and after harvesting, adopting a method of removing a plurality of sprouts growing on stumps year by year, reserving 3-4 branches / stump in the first year, removing the sprouts to 1-2 branches / stump in the second year, and finally reserving 1 branch / stump in the third year; and e. replacement of old-growth forest: after intermediate cutting for three times, using cuttings or cultivated new saplings for replacing the stumps with reduced regenerative capacity, or conducting grafting treatment on magnolia officinalis sprouts by taking the stumps with low capability as rootstocks.

Description

technical field [0001] The invention relates to a cultivation method of magnolia officinalis, 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, wild resources have been mainly used for medicinal Magnolia officinalis. Due to increasing demand and 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 officinalis artificial forests have been carried out, there are not many Magnolia officinalis forests with good stand quality. Due to the lack of scientific guidance in artificial planting planning, and with the thinning and harvesting of Magnolia officinalis resources, the impact of diseases and insect pests, or the induction of natural factors (mainly referr...
