Method of improving seedling rate of magnolia biondii

Abstract

The invention belongs to the technical field of tree planting and particularly relates to a method of improving seedling rate of magnolia biondii. The method comprises treatment of seeds and management of a seedling stage, wherein the treatment of seeds comprises the following steps: keeping the temperature of a hydrochloric acid liquid at 3-5 DEG C for later use; putting the heated seeds in the hydrochloric acid liquid for later use; stirring the mixture for 2-4min by means of a stirring device; and washing the same with a sodium hydroxide liquid for 8-12min, wherein the stirring device comprises a rotary shaft, groups of stirring blades are uniformly distributed in the radial direction of the rotary shaft, and the stirring blades are fixed and wrapped by hemp materials; the management ofthe seedling stage comprises the followings steps: collecting and filtering the hydrochloric acid liquid which treats the seeds for 3-4 times; mixing the obtained filtrate with biogas slurry in a weight ratio of 1: (3-4) to obtain a mixed liquid; and diluting and spraying the mixed liquid. The whole process can be mechanically operated, the seedling rate of magnolia biondii reaches about 90%, thesurvival rate of the seedlings reaches 97% or above, and the economical benefit is remarkable.

Description

technical field [0001] The invention belongs to the technical field of tree planting, and in particular relates to a method for improving the seedling rate of magnolia wangchun seeds. Background technique [0002] Wangchun magnolia, also known as Wangchunhua and Yingchun tree, belongs to the perennial deciduous tree of Magnoliaceae Magnolia. The general tree height is 6-12 meters, the highest can reach 25 meters, and the male diameter is 1.4 meters. It can treat symptoms such as nasal congestion, headache, rhinitis, sinusitis, etc. In addition, Wangchun Magnolia has beautiful properties and fine material. It is a good timber tree and woody flower species for traditional Chinese medicine, with high economic value. Wangchun Magnolia is mostly wild. With the continuous development of economic value, there are more and more cases of artificial planting of Wangchun Magnolia. During artificial production, seedling seedlings and transplanting methods are often used, but because the...

Problems solved by technology

Wangchun Magnolia is mostly wild. With the continuous development of economic value, there are more and more cases of artificial planting of Wangchun Magnolia. During artificial production, seedling seedlings and transplanting methods are often used, but because there is a layer of wax on the outside of the seeds, it is generally Using plant ash mixing, wet sand mixing, soaking in warm water, and manual rubbing to remove the wax to remove the wax requires a lot of time and procedures, and the seedling rate after this treatment is generally about 35%. In order to improve the economy benefits, this problem should be addressed
