A tree eggplant and a cultivation method, a rapid propagation method and an application thereof are provided by the present disclosure. In the present disclosure, the Solanum wrightii is specifically selected as the female parent, and the Solanum torvum is used as the male parent, and the tree eggplant variety obtained by hybridization has fast growth, developed trunk, strong growth potential, and is perennial, and is strong in photosynthesis, strong in nutrient and water absorption capacity, high in affinity with the scion, fast in healing at the scion interface of the rootstock and good in healing; and has good resistance to soil-borne diseases such as fusarium wilt, verticillium wilt, bacterial wilt and root knot nematode; and the rapid propagation method of the tree eggplant has strong operability and high efficiency, and is easy to popularize in practical application.

Provided is a cultivating material composition including a cultivating substrate and a bio-cellulose film, wherein the bio-cellulose film is in contact with the cultivating substrate, such that highly increased yield and quality of crops, a shorter harvest period, less water and nutrient sources, and low cost can be achieved.

A method for growing a seedling, the method includes specifying a growth-contributing fungus contributable to growth of a target plant to be grown artificially, isolating the growth-contributing fungus, culturing the isolated growth-contributing fungus to obtain an inoculum, growing the inoculum with a growth substrate to obtain a microorganism bed, and rooting and growing the target plant in compost including the microorganism bed. In the specifying a growth-contributing fungus contributable to growth of a target plant to be grown artificially, the growth-contributing fungus is an indigenous nonmycorrhizal filamentous fungus to inhabit a planting site in which the target plant is to be planted or a neighborhood of the planting site and to live in symbiosis with a plant without a mycorrhiza.

The composition contains, as essential components, coconut fibers, compost of sheep manure and Glomus iranicum var. tenuihypahrum. The composition is included into a bag that has at least two parts joined together through at least a first weakened portion, allowing to separate it into two bags each having an opening wherein the composition contained in the bag parts is accessible. The composition inside each of the bags is contacted with a plant or at least a seed via the opening.

The present invention provides a slope repair method. The method includes pretreating a slope, so that an average roughness of the pretreated slope is not greater than ±8 cm to ±12 cm per linear meter; (2) hanging a hard protective mesh on the pretreated slope, where the distance between the hard protective mesh and the slope is 3-4 cm, and the hard protective mesh has an aperture size of 4-6 cm; and (3) spraying a loam-like matrix on the slope with the hard protective mesh hanged, where the loam-like matrix includes not less than 0.04/m.sup.2 of plant seeds; the plant seeds include tree seeds, shrub seeds and herb seeds with a mass ratio of (2.5-3.5):(4-6):(1.5-2.5). The method provided by the present invention effectively restores the mountain vegetation, and only needs 1-2 years of artificial maintenance after the restoration to form a cyclically stable ecosystem.
