Container nursery method for magnolia

Abstract

The invention provides a container nursery method for magnolia. The container nursery method includes harvesting seeds, cleaning seeds, drying seeds in shade, breaking dormancy to accelerate germination of the seeds, preparing base materials and containers, bagging the seeds, supplying nutrition to the seeds in black bags, cultivating by changing the black bags, and thereby obtaining the magnolia seedlings. Compared with the prior art, the container nursery method for the magnolia has the advantages that seedling cultivation time is shortened, the seeds begin to sprout after 20 days since the seeds are harvested and cleaned, the cultured seedlings are high in uniformity, the average sprouting percentage of the seeds is increased by 85% above, and the outplanting percentage is up to 95%.

Description

Technical field: [0001] The invention belongs to the field of plant propagation, in particular to a method for growing magnolia plants in containers. Background technique: [0002] At present, a few species of Magnoliaceae plants have successfully bred some offspring through cuttings, grafting, tissue culture and other asexual reproduction methods. However, due to the advantages of economical application, convenient portability, and rich genetic diversity, most Magnoliaceae plants still use Seed reproduction. Forestry institutions and scientific research institutes all over the country have conducted a lot of research on the seedling raising techniques of multiple Magnoliaceae tree species. [0003] At present, most of the main sowing seedlings are nursery seedlings. The specific technical steps are: (1) Harvesting seeds: harvesting seeds during the ripening season, and harvesting seeds too early or too late will affect the germination rate; (2) Seed cleaning : The harvest...

AI Technical Summary

Problems solved by technology

[0005] The traditional nursery technology of magnolia plants has the following disadvantages: (1) in the cultivation of magnolia seeds, the germination rate is generally low, according to statistics, the germination rate is between 13% and 80%; (2) it is affected by seasons, Due to technical limitations, the seeds have a storage period of about 4 months, which prolongs the cultivation period of seedlings; (3) The density of seedlings in the nursery is different, and the seedlings are prone to be squeezed in the later stage, which affects the quality of seedlings; (4) The seedlings need to be transplanted when they come out of the nursery, and there is one more transplanting process, and the root system of the seedlings must be damaged during the transplanting process, which will cause the death of the seedlings in the later stage and reduce the survival rate of the seedlings

[0006] The shortcomings of the traditional container seedling raising technology are: (1) The seed storage period is about 4 months, which prolongs the cultivation period of the seedlings; When transplanting into a container, it is easy to damage the root system of the seedling if you don’t pay attention to it when transplanting. At the same time, there is a process for the root system of the seedling to fuse with the substrate in the container. growth rate
