Description
[01] The present disclosure relates to the technical field of plant growing, and in particular to a container seedling substrate for Lithocarpus polystachyus and a seedling raising method.
[02] Lithocarpus polystachyus is a tree species of the genus Lithocarpus of the family Fagaceae, mainly distributed in the provinces south of the Yangtze River in China. Traditionally, the folks often harvest L. polystachyus leaves for making tea, which has a long drinking history. Modern medicine has confirmed that Z. polystachyus is rich in a variety of nutrients, trace elements and vitamins necessary for the human body; phloridzin, trilobatin and flavonoids are the main biological active ingredients thereof, which have anti-inflammatory, antioxidant, hypoglycemic/hypolipidemic, and diabetes-controlling effects. Because Z. polystachyus is mostly available from wild resources, natural habitats thereof have been destroyed and wild resources have declined sharply with the increase in resource usage. Therefore, it is very necessary to carry out the artificial breeding and cultivation of L. polystachyus to conserve the natural germplasm of 1. polystachyus and meet the demand for high-quality raw materials in the future.
[03] At present, the research on the artificial cultivation of L. polystachyus has just started, mainly focusing on the research on cutting seedling raising technology of L. polvstachvus, and effects of planting density and light on seedling survival and sapling growth. Compared with ordinary bare-root seedlings, container seedlings of forest trees have the advantages of well-developed root system, easy transport, long afforestation season, high survival rate, and appropriateness for afforestation at difficult sites. Corresponding container seedling experiments have been carried out in roburs and oaks, like Quercus aliena, Quercus variabilis, Quercus ilex, and Quercus robur, and have achieved excellent results. For example, container seedlings of Quercus velutina cultivated by RPM technology can reach 2.5 times the diameter at breast height (DBH) of ordinary bare-root seedlings after 10 years of afforestation. L. polystachyus has the typical characteristics of tree species of the family Fagaceae. That is, the seedlings have developed axial roots, sparse lateral roots, and low afforestation survival rate, and grow slowly. Cultivating large-sized container seedlings is conducive to improving the morphological quality and the level of nutrient pools in the tissue, increasing the afforestation survival rate and promoting stand growth. However, there are relatively few studies on the cultivation of large-sized container seedlings of Z.
polystachyus. Therefore, in order to improve the quality of the seedlings of 1. polystachyus, it is very necessary to carry out research on the raising technology of container seedlings of I.

[29] Examplel
[30] Cutting seedlings of L. polystachyus were cultivated in seedling containers with a diameter x length of 15 x 20 cm. Seedling substrates in the seedling containers were separately set as follows: Al: peat, rice husk-sawdust mixture and yellow subsoil mixed in a ratio of 3:6:1; A2: peat, rice husk-sawdust mixture and yellow subsoil mixed in a ratio of 4:4:2; and A3: peat, rice husk-sawdust mixture and yellow subsoil mixed in a ratio of 5:2:3; 3.0 kg of slow-release fertilizer was added per 1 m® of the substrate, and growth indexes of container seedlings of L. polystachvus were measured to obtain Table 1 below.

[62] Example 8
[63] In December, 2018, after the I. polvstachyus seedlings in Examples 4 to 7 and Comparative Examples 1 to 3 stopped growing, the seedling height and ground diameter of each seedling in each example were measured, and the height-diameter ratio was calculated; the ground diameter was measured with a digital vernier caliper; the seedling height was measured with a tape measure, and the calculation formula of the height-diameter ratio was: height-diameter ratio = seedling height/ground diameter.
[64] 10 healthy plants were randomly selected from Examples 4 to 7 and Comparative Examples 1 to 3, respectively, and the biomass of the seedlings was measured. During biomass measurement, the seedlings of each example were divided into three parts: roots, stems, and leaves. After water-removing at 105°C for 2 h, the seedlings were dried in a constant temperature oven at 80°C to constant weight. The biomass of each part was measured with an electronic balance; root-shoot ratio was calculated, and the calculation formula of the root-shoot ratio was: root-shoot ratio = aboveground biomass/belowground biomass. Furthermore, the root length, root surface area, root diameter, root volume and number of root tips of the seedlings were measured with a WinRHIZO root-measuring system, and Tables 4 and 5 were obtained.

[67] From Tables 4 and 5 above, the seedling raising methods for L. polystachyus in Examples 4 to 7 of the present disclosure can significantly improve the growth performance of L. polystachyus seedlings, and also help improve the root indexes of the L. polystachyus seedlings, providing a scientific basis for the cultivation of high-quality container seedlings of L. polystachyus.
[68] Example 9
[69] The membership function method was used to comprehensively evaluate the seedling raising indexes of different seedling raising methods of the foregoing Examples 4 to 7 and Comparative Examples 1 to 3, and Table 6 was obtained.
[70] To achieve data processing and statistical analysis, WPS Excel was used for basic data statistics, and SPSS 22.0 statistical software was used for membership function. The calculation formula of the membership function 1s: U(x;) = (Xi - Xmin)/(Xmax - Xmin), Where x; is a measured value of an index, Xmax is a maximum value of a processing index, and Xmin is a minimum value of a processing index.

[72] From Table 6, the maximum of integrated average membership function value of Example 4 is 0.7712, and the average membership function values of growth and root indexes are 0.8964 and
0.646, respectively, ranking first, and showing the best seedling raising effect. Meanwhile, the above results indicate that, when raising L. polystachyus seedlings, if the optimal seedling substrate ratio, application amount of slow-release fertilizer, and specification of seedling raising bag are selected as seedling raising conditions, respectively, the final seedling raising effect of the container seedlings of Z. polystachyus may not be necessarily the best; the seedling substrate ratio, the application amount of slow-release fertilizer and the specification of the seedling raising bag influence each other, and jointly determine the seedling raising effect of ZL. polystachyus.
[73] It can be seen from the above-mentioned examples that the container seedling raising method for LZ. polystachyus provided by the present disclosure can significantly improve the growth indexes of L. polystachyus seedlings; the growth indexes, including seedling height, ground diameter, height-diameter ratio, aboveground biomass, root biomass, stem biomass, leaf biomass, and total biomass, are increased by 0.49-5.25 times. Meanwhile, the method of the present disclosure is beneficial to improve the root indexes of the L. polystachyus seedlings, in which the volume and the number of root tips are increased by 2.48 and 2.62 times, respectively, providing a scientific basis for the cultivation of high-quality container seedlings of L. polystachyus.
[74] The above are only the examples of the present disclosure and therefore do not limit the patent scope of the present disclosure. Any equivalent structure or equivalent process transformation used according to the contents of the specification in the present disclosure, no matter whether it is directly or indirectly used in any other related technical field, should be included within the scope of patent protection of the present disclosure.
