Seedling culture container for the cyclocarya paliurus and seedling raising method for improving cyclocarya paliurus seedling quality

Abstract

The invention discloses a seedling culture container for the cyclocarya paliurus and a seedling raising method for improving cyclocarya paliurus seedling quality. The seedling culture container for the cyclocarya paliurus comprises an inner bag and an outer bag arranged on the outer side of the outer wall of the inner bag in a sleeving mode, wherien the inner bag is a non-woven fabric bag; the outer bag is a woven cloth bag; and the non-woven fabric bag and the woven cloth bag are sleeved together, vertical openings are formed in the adjacent side walls of the non-woven fabric bag and the woven cloth bag, the non-woven fabric bag and the woven cloth bag which are located on the same side of the openings are overlapped to form a layer, and zippers are arranged along the two side edges of the openings. The seedling culture container for cyclocarya paliurus is provided with the inner bag and the outer bag; the inner bag is the non-woven fabric bag; the outer bag is the woven cloth bag; the woven cloth bag can keep moisture for plants, and the heat preservation and moisture preservation bag of the double-layer structure has good air permeability, so that air at the roots of seedlings has fluidity, accumulated water is not prone to being generated at the roots, and the roots are prevented from rotting.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a seedling raising container for Cyclocarya paliurus and a seedling raising method for improving the quality of Cyclocarya seedlings. Background technique [0002] Cyclocarya paliurus (Batal.) Iljinskaja, also known as Cyclocarya paliurus (Batal.) Iljinskaja, is a plant of the genus Cyclocarya paliurus (Batal.) Iljinskaja in the class Dicotyledoneae. It is a unique single-species genus of plants in my country, one of the endangered plants under national key protection, and belongs to the third category of protected plants. When cultivating seedlings of Cyclocarya paliurus in the open field, due to the deep dormancy characteristics of the seeds, the germination rate in the field is low, the average germination time is long, and the emergence period lasts for a long time, up to 2-5 months, resulting in irregular seedling emergence and seedling growth.

Problems solved by technology

When cultivating seedlings of Cyclocarya paliurus in the open field, due to the deep dormancy characteristics of the seeds, the germination rate in the field is low, the average germination time is long, and the emergence period lasts for a long time, up to 2-5 months, resulting in irregular seedling emergence and seedling growth. The quality of seedlings is uneven, and the quality of seedlings varies greatly. The number of first-grade seedlings is only 12.7%, and the number of qualified seedlings is only 61.4%. less, so the slow seedling period is long, and the survival rate of afforestation is low. At the same time, due to the large difference in seedling quality, the seedling differentiation is serious, the afforestation preservation rate is low, and the forest phase of the young forest stage is poor, which seriously affects the cultivation of Cyclocarya paliurus plantation resources and their With the development of industrialization, with the rapid development of Cyclocarya paliurus industry, in order to improve the quality of seedlings of Cyclocarya paliurus, the cultivation of artificial forest resources tends to use seedling container seedlings for afforestation

[0003] At present, the seedling containers used in the market are mainly divided into two categories: containers that can be planted into the soil and containers that cannot be planted into the soil. The first type of containers can be planted into the soil together with the seedlings, including various paper nutrition cups, non-woven fabrics, etc. The container can be degraded in the soil, but it is easy to break during use, it is not easy to carry, and the service life is short, while the non-woven container is thin and has large pores, which causes the seedlings and seedling substrate to lose water too quickly, so it is necessary to replenish water in time , During the process of raising seedlings, the amount of irrigation water is large, and the water will flow out from the gaps of the non-woven fabric, resulting in waste of water

The second type of containers cannot be planted into the soil together with seedlings, including various plastic containers, ceramic containers and seedling trays. These containers are not easy to break, easy to carry, can be used continuously, have a long service life, and have good soil protection effects. One of the most commonly used seedling containers, but this type of container has poor air permeability and water permeability, the root system is easy to age and rot, and entangled roots and coiled roots are prone to occur in the container
