Problems solved by technology

The current cultivation techniques are: large seedlings (2 years old), sparse planting (plant spacing 2m×3m), extensive management, harvesting in 25 to 30 years, digging up and down with roots, bark, dry bark, and root bark are all used as medicine. The purple oil Magnolia not only grows slowly, has low yield, but also has poor quality, only one-time income, and the overall economic benefit is not high

Embodiment Construction

[0020] In order to describe the present invention in more detail, the present invention will be further described in detail below in conjunction with specific implementation examples.

[0021] The technical route adopted by the present invention is: seed selection, rare seedling cultivation, small seedling planting, planned dense planting, reasonable spacing, annual cutting and harvesting, and regrowing forests to achieve one-time afforestation and long-term benefits. Its specific regenerative cultivation method is as follows:

[0022] 1. Selected seeds. Ziyou Magnolia began to flower and set seeds in 15 years. However, the seedlings before 20 years old are low in seedling growth, and the seedlings are weak and grow slowly. The seed selection of the present invention includes two aspects: 1. selecting mature and more than 20-year-old mother trees for seed collection;

[0023] 2. Raise seedlings evenly. The prior art raises 30,000 to 35,000 plants / mu, and the seedlings are ...

Abstract

The invention discloses regeneration cultivation technology for cortex magnoliae officinalis. The technology comprises the following steps: performing seed cleaning; selecting sparsely planted strong seedlings, wherein the density is lower than 20,000 to 25,000 plants per mu, the neck size is more than and equal to 1.0 centimeter and the average height is 30 to 50 centimeters; performing fixed planting of young seedlings; performing planed compact planting; and starting intermediate cutting since the fifteenth year, and in the intermediate cutting, leaving roots, barks and butts, loosing earth and applying additional fertilizer(oil cakes), and spraying 50 to 100ppm indolylacetic acid to prompt latent buds of butts to burgeon and quickly grow into forest. Therefore, the users can enjoy long-term benefits by once forestation.

Description

technical field [0001] The invention relates to a cultivation technology of Magnoliaceae plants, in particular to a regenerative cultivation method of Magnolia officinalis. Background technique [0002] Magnolia officinalis belongs to Magnoliaceae, a broad-leaved deciduous tree with a height of up to 15m. It is a national Class II protected tree species and one of the precious Chinese herbal medicines. The current cultivation techniques are: large seedlings (2 years old), sparse planting (plant spacing 2m×3m), extensive management, harvesting in 25 to 30 years, digging up and down with roots, bark, dry bark, and root bark are all used as medicine. The purple oil Magnolia not only grows slowly, has low yield, but also has poor quality, only one-time income, and the overall economic benefit is not high. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages, and provide a cultivation method that can make Magno...
