The present invention discloses a stichopus japonicus grading breeding method. It is characterized by that said method includes the following steps: making sex glands of Chinese stichopus japonicus and Chinese-Russian hybrid stichopus japonicus be simultaneously developed and matured, using shade-drying parturifacient method to respectively obtain sperm of Chinese stichopus japonicus and ovum of Chinese-Russian hybrid stichopus japonicus, making artificial insemination and incubating fertilized ovum until the laval plankton is formed, after the laval plankton is attached, utilizing conventional method to breed F1 generation of stichopus japonicus of Chinese stichopus japonicus and Chinese-Russian stichopus japonicus, then using said F1 generation stichopus japonicus as seed stichopus japonicus, accelerating the sex glands of said F1 generation stichopus japonicus and Chinese stichopus japonicus to make them be synchronously matured, making artificial insemination and breeding so as toobtain a new young of stichopus japonicus.

The invention discloses a cutting breeding technology of vine tea, which comprises the following steps: (1) selection of nursery land; (2) deep plowing and land preparation and base fertilizer application; (3) soil disinfection; Ridging and covering with plastic film; (5) green branch cutting; (6) nursery field management; (7) nursery stock transplantation; it is characterized in that the green branch cutting method and the bed making of the seedbed. Compared with the prior art, the invention can improve the survival rate and yield of vine tea plants; shorten the soaking time and improve the cutting efficiency; and is suitable for large-scale cultivation and transplantation.

The invention provides a culture substrate for dendrobium candidum tissue-cultured seedlings. The culture substrate comprises a first substrate layer, a second substrate layer, a third substrate layer and a fourth substrate layer from top to bottom sequentially, wherein the first substrate layer is formed by mixing laying of one or two kinds of crushed wood shavings and crushed bark, the second substrate layer is formed by laying of a plurality of small wood blocks, the third substrate layer is formed by laying of a plurality of long wood strips, and the fourth substrate layer is formed by laying of a plurality of crushed stones. According to the culture substrate for the dendrobium candidum tissue-cultured seedlings, the first substrate layer, the second substrate layer, the third substrate layer and the fourth substrate layer are arranged from top to bottom sequentially, and the substrate layers are made of different materials, so that the culture substrate for the dendrobium candidum tissue-cultured seedlings is low in pathogenic microorganism content and high in air permeability, seedling hardening is not required to be conducted when the substrate is used for culturing the dendrobium candidum tissue-cultured seedlings, and the survival rate of cultivation is high.

The invention relates to bonsai cultivation methods, in particular to a making method of a tea tree bonsai. The making method comprises the following steps that firstly, a Fuyun No.6 tea tree is selected as a female parent, a Foshou or Xiaoqi tea tree is selected as a male parent, artificial hybridization is performed, and tea seeds of a single offspring plant are obtained; secondly, the tea seeds are planted in a pot; thirdly, normal temperature and humidity of soil in the pot are well kept after germination of the tea seeds; when growing to 18-22 cm, the tea tree seedlings are inspected and screened, and the tea tree seedlings integrating excellent characteristics of the male and female parents are selected for styling. According to the making method of the tea tree bonsai, firstly, the Fuyun No.6 tea tree which is high in stress resistance, wide in adaptability and high in planting survival rate serves as the female parent during artificial hybridization, and the rare tea tree variety, namely the red-shoot or green-shoot Foshou tea tree which is unique in leaf structure, rich in leaf type and diversified in leaf color and shoot and leaf color serves as the male parent. Through the making method, the problems that an original tea tree bonsai is simplex in variety, monotonous in style, low in survival rate, slow in growing trend, poor in insect resistance, prone to aging, high in management difficulty and the like are solved.
