Problems solved by technology

However, the non-woven fabric containers currently used in production are usually small in size, and they are not adapted to the characteristics of the seedlings. Especially for the deep-rooted tree species of Quercus liaotungensis, they cannot adapt to the characteristics of the root system of the seedlings and cannot achieve the goal of cultivating high-quality and strong seedlings. If the container is too deep or too large, it will directly lead to an increase in the filling matrix and an increase in cost
At present, there is no research on the structural optimization of seedling root balls in light-weight substrate Quercus liaotungen non-woven containers

example 1

[0028] Example 1: A method for optimizing the seedling root mass of a light-weight substrate Quercus liaodong non-woven container, the steps are: preparation of substrate, treatment of seeds, preparation of seedling container, preparation of seedbed, seed sowing, seedling stage management, air cutting root, data Investigation; fill the prepared substrates in the corresponding nursery containers of several specifications, sow the treated high-quality Quercus liaotungensis seeds in non-woven fabrics, carry out conventional nursery technology maintenance in the growing season, and measure the various items after the seedlings stop growing in autumn. growth indicators.

[0029] Specific steps are as follows:

[0030] According to peat soil: perlite: vermiculite: decomposed bark 2.5:2.5:2.5:2.5 (volume ratio), mix and stir evenly, and add 2% calcium superphosphate as base fertilizer; use 40% formalin Dilute the solution 800 times and pour the substrate, and the water content of th...

example 2

[0047] Example 2: In order to further prove the effect of the present invention, a non-woven container seedling with a specification of 6cm×25cm and a 16cm×16cm black nutrition pot container seedling were selected to carry out a comparative test. The test methods of substrate ratio, seed sowing, and seedling management are the same as those of Example 1. Randomized block design, one treatment is randomly arranged in each plot, and each treatment has 30 generations (pots). The growth indicators such as seedling height and ground diameter are counted, and the specific data are shown in Table 3. It can be seen that the strong seedling index of the 6cm×25cm non-woven container seedlings is significantly higher than that of the control black nutrition pot container seedlings.

[0051] Example 3: In order to further prove the effect of the present invention, the non-woven container seedlings and plug seedlings of 6cm×25cm specifications were selected to carry out a comparative test. The test method is the same as that of Example 2, and the specific data are shown in Table 4. It can be seen that the strong seedling index of 6cm×25cm non-woven container seedlings is significantly higher than that of control plug seedlings.

Abstract

The invention belongs to the technical field of forest tree seedling cultivation. Aiming at problems such as nest roots existing in container seedling cultivation, it provides a method for optimizing the container seedling root mass of Quercus liaotungen non-woven fabric with a light substrate. The main method includes substrate preparation, seed treatment, and seedling cultivation. Container preparation, seedbed preparation, seed sowing, seedling management, air root cutting, data investigation; fill the prepared substrate in the corresponding specifications of the seedling container, and sow the treated high-quality Quercus liaotungen seeds in the non-woven fabric In the growing season, conventional seedling raising techniques are carried out. After the seedlings stop growing in autumn, various growth indicators are measured. And after comprehensive analysis and comparison, the suitable container size for Quercus liaotungen seedlings with light substrate non-woven fabrics was screened out. The Quercus liaotungensis cultivated with this container specification has a robust root system, complete root mass structure, neat and robust growth of seedlings, significantly improved the quality of Quercus liaotungungen seedlings and the survival rate of afforestation, and has good ecological, economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of forest tree seedling raising, and in particular relates to a method for optimizing the root mass of light-weight matrix Liaodong oak non-woven container seedlings. Background technique [0002] Liaodong oak ( Quercus wutaishansea ) is of the Fagaceae genus Quercus ( Quercus ) is the main constructive tree species and dominant tree species in the warm temperate deciduous broad-leaved forest in my country. Liaodong Quercus is a deep-rooted tree species with developed root system. It has the characteristics of cold resistance, drought resistance, barren resistance, and strong stress resistance. It is an excellent ecological tree species for returning farmland to forest. , the sustainable development of natural forests, etc. play an important role. Liaodong Quercus has a wide range of uses, the wood is hard and rot-resistant, and can be used for construction, ore pillars, ships, etc. Its seeds are rich in...
