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 Quercus liaotungen non-woven container with light substrate, the steps are: substrate preparation, seed treatment, seedling container preparation, seedbed preparation, seed sowing, seedling management, air root cutting, data Investigation: fill the prepared substrates in the corresponding seedling containers of several specifications, sow the treated high-quality Quercus liaotungensis seeds in non-woven fabrics, carry out conventional seedling raising technology maintenance during the growing season, and measure the seedlings 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 superphosphate with a weight ratio of 2% as base fertilizer; use 40% formalin Dilute the solution 800 times and sprinkle the substrate, the water content...

example 2

[0047] Example 2: In order to further prove the effect of the present invention, choose the non-woven container seedling of 6cm * 25cm specification and 16cm * 16cm black nutrient bowl container seedling to carry out comparative test. The test methods of substrate ratio, seed sowing, seedling management, etc. are the same as Example 1. Randomized block design, each plot is randomly assigned a treatment, and each treatment has 30 generations (bowls). The growth indicators such as seedling height and ground diameter were 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 fabric container seedlings is significantly higher than that of the control black nutrient pot container seedlings.

example 3

[0051] Example 3: In order to further prove the effect of the present invention, the non-woven fabric container seedling and plug seedling of 6cm * 25cm specification were chosen to carry out 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 the 6cm×25cm non-woven fabric container seedlings is significantly higher than that of the control plug seedlings.

Abstract

The invention belongs to the technical field of seedling raising of forest, and provides a method for optimizing light-substrate non-woven fabric container seedling root balls of quercus wutaishanseain order to solve the problem that at present, during seedling raising with containers, roots are bent. The main method comprises steps of compounding substrates, performing seed treatment, preparingseedling raising containers, preparing seedbeds, sowing seeds, performing seedling stage management, cutting roots in air, and performing data survey. The prepared substrates are loaded in corresponding seedling raising containers having many specifications, treated superior quercus wutaishansea seeds are sown in non-woven fabrics, conservation is performed in growth seasons through a conventionalseedling raising technique, and after seedlings stop growth in autumn, various growth indexes are measured. Through comprehensive analysis and comparison, the container specification suitable for light-substrate non-woven fabric seedling raising of the quercus wutaishansea is screened out. The quercus wutaishansea cultivated through the container specification is strong in root systems and complete in root ball structure, seedlings grow tidily and strongly, the quality and the forestation survival rate of quercus wutaishansea seedlings are notably increased, and the method has good ecologicalbenefits, economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of tree seedling cultivation, and in particular relates to a method for optimizing the seedling root mass of a light-duty substrate Quercus liaotungen nonwoven fabric container. Background technique [0002] Quercus liaotungensis ( Quercus wutaishansea ) is a family of Fagaceae (Fagaceae) of the genus Quercus ( Quercus ) deciduous trees are the main building species and dominant tree species of deciduous broad-leaved forests in the warm temperate zone in my country, and also one of the excellent tree species for building coniferous and broad-leaved mixed forests in North China, and are important zonal forest vegetation communities. Quercus liaotungensis is a deep-rooted tree species with a well-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 forests...
