Method for raising seedlings of golden camellia tea in light matrix container

Abstract

The present invention discloses a light-substrate container seedling raising method for golden camellia. The present invention aims at providing the light-substrate container seedling raising method for the golden camellia, which is low in cost, balanced in nutrients and strong in operability, can accelerate the germination rate and the growth speed of the golden camellia, and also can solve the problems that the survival rate of traditional seedling raising is low and the transportation cost of nursery-grown plants is high. The method sequentially comprises the following steps of: (1) picking and storing seeds; (2) accelerating germination of the seeds; (3) transplanting the golden camellia seeds subjected to the germination acceleration into a container filled with a light substrate, drenching the seeds thoroughly and shadowing the seeds; the light substrate being prepared from peat soil, wood dust and yellow soil in a volume ratio of 8 to (0.8-1.2) to (0.8-1.2); (4) keeping the substrate wet and shadowing the seeds after the seeds germinate, spraying a pesticide for preventing plant diseases and insect pests once every 1-2 months, and keeping a nursery garden clean and sanitary; and (5) transplanting nursery-grown plants out of the nursery garden. The light-substrate container seedling raising method for the golden camellia belongs to the technical field of plant cultivation.

Description

technical field [0001] The invention relates to a method for raising seedlings, in particular to a method for raising seedlings of Camellia japonica light substrate containers, belonging to the technical field of plant cultivation. Background technique [0002] Camelia nitidissima (Camelia nitidissima) is a plant of the Theaceae, Camelia, Sect.Chrysantha Chang group. It is an evergreen shrub or small tree. Because it is the only group of camellias with yellow flowers, it is known as "" The "Queen of the Tea Clan" and "The Giant Panda in the Botanical Kingdom" have aroused widespread attention in the fields of botany and horticulture at home and abroad, especially the International Camellia Society. It has been listed as a national first-class protected plant and is a rare ornamental plant in the world. and germplasm resources. Golden camellia contains a variety of trace elements, amino acids, vitamins, tea polyphenols, tea polysaccharides, flavonoids, saponins, etc., which ...

AI Technical Summary

Problems solved by technology

The disadvantages of direct seedling cultivation in the field are reflected in the following aspects: (1) Raising seedlings on flat land needs to occupy a certain amount of land, which will greatly increase production costs in today's land resource shortage

(2) There are too many seeds used for raising seedlings on flat land. Generally, the amount of seeds used for direct seeding is more than that for transplanting seedlings. However, the yield of Camellia japonica seeds is already very low, so a certain amount of seeds will be wasted for raising seedlings on flat land.

(3) The soil in the field is difficult to arrange too finely, and it is difficult to control the temperature, moisture, and sowing depth under the environmental conditions suitable for seed germination and seedling growth, which may easily cause serious seedling shortage

(4) Too much labor and difficult management, and it is difficult to control the management work such as fertilization, watering, intertillage and soil loosening in the seedling stage within a suitable range.

(6) The weight of the soil is heavy, the labor intensity of handling is high, and the transportation cost is high

(7) It is easy to cause damage to the root system when transplanting, which affects the absorption, synthesis, storage and other functions of the root system, making the seedling slow seedling period long and the survival rate of transplanting low

However, the role of light substrate in Camellia camellia seedling cultivation has not been reported, and further research is needed
