Method for raising taiwania flousiana gaussen light-matrix container seedling

Abstract

The invention belongs to the technical field of cultivation of hops, grapes, fruit trees or similar trees, and discloses a method for raising a taiwania flousiana gaussen light-matrix container seedling. The method comprises the processes of taiwania flousiana gaussen superior seed source selection, nursery land selection, matrix material and seedling container selection, seeding, seedling transplanting, nursery management and the like, and is cahracteried in that guizhou or yunnan taiwania flousiana gaussen seed sources which grow well in guangxi are adopted, and from February to March of thenext year, the taiwania flousiana gaussen light-matrix container seedling is cultivated and obtained through seeding, seedling transplanting, nursery management and other measurements. The method forraising the taiwania flousiana gaussen light-matrix container seedling has the advantages that the quality of the seedling is good, the seedling has multiple roots, and the root system is developed,stretched completely and penetrates through a mesh bag easily, thereby improving the stress resistance of the seedling and being capable of improving the survival rate of afforestation; an adopted non-woven container is degraded easily, the matrix weight is light, the seedling cost is low, the promotion is easy, a taiwania flousiana gaussen artificial forest is developed for guangxi or surroundingareas, the sustainable and healthy development of forestry is promoted, a seedling raising method is provided, and the method has higher economic benefits, social benefits and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of cultivation of hops, grapes, fruit trees or similar trees, and relates to a method for cultivating seedlings in a light substrate container of bald fir. Background technique [0002] Bald fir (Taiwania flousiana Gaussen) is also known as soil fir and Southwest Taiwan fir. It is an evergreen tall tree belonging to the Chinese Taiwan fir genus of the Chinese fir family. The tree is tall, with a tallest plant up to 75m and a diameter at breast height of more than 2.5m. Naturally distributed in the southeast of Guizhou Province, west of Yunnan Province and southwest of Hubei Province in my country, the distribution area spans between 24°31′-30°08′ north latitude and 97°34′-109°08′ east longitude, and is vertically distributed at altitudes Between 800 and 2500m, it is a rare plant in the world unique to my country, and is now a second-class protected tree species. Bald fir has the characteristics of strong ad...

Problems solved by technology

Because the soil in the nursery (that is, the culture medium) is relatively compact and has poor air and water permeability, it is not conducive to the growth of the root system of the seedlings, resulting in uneven seedlings, and it is easy to cause damage to the root system when the seedlings emerge from the nursery. Coupled with inconvenient transportation, the afforestation time is not suitable for drought weather and can be extended, and the nursery is often replaced every year

[0005] (2) Traditional plastic film container bag seedling cultivation method

[0007] Because the traditional bare-root seedling raising method and the plastic film container bag seedling raising method of bald fir seedlings both use yellow core soil as the main culture substrate, the soil is compact, and the ventilation and water permeability are poor. Because the root system of the seedlings is young, it is difficult to intersperse and grow in the substrate. Therefore, it is not conducive to the growth of the root system of seedlings, so the root system of seedlings is not developed enough, and the stress resistance of seedlings is also weak, and the seedlings cultivated by the bare root seedling method are easy to cause damage to the root system when they go out of the nursery, and the seedlings cultivated by the plastic film container bag seedling method need to be removed when planting. Containers, afforestation construction efficiency is not high, it is difficult to meet the large-scale promotion and construction of bald fir forests in the current society.
