Seedling culture method for Camellia oleifera

Abstract

The invention discloses a seedling culture method for Camellia oleifera. The seedling culture method for Camellia oleifera comprises the following steps: (1) picking of cutting leaves; (2) preparationof a seedling culture substrate: mixing, in parts by weight, 100 parts of sandy loam, 50-70 parts of clay, 15-20 parts of expanded perlite, 10-15 parts of earthworm soil, 10-15 parts of plant ash, 10-12 parts of magnesium ammonium phosphate, 0.1-0.2 part of biological pesticide and 30-35 parts of organic fertilizer uniformly, wherein the biological pesticide comprises the following raw materials:in parts by weight, 4-8 parts of nano titanium oxide, 1-2 parts of Bacillus thuringiensis and 2-4 parts of Berberine; (3) treatment of the cutting leaves: adding the cutting leaves to a 500-fold growth enhancer solution, and performing soaking at 15-25 DEG C for 2-3 h; (4) cuttage; (5) management after cuttage: constructing a shed for sun shading, maintaining the humidity of the seedbed substrateat 65-70%, performing dressing of urea once at the dosage of 25-30 g / m<2> every time the plant height of Camellia oleifera seedlings is increased by 3-4 cm; and (6) transplantation. The cutting-leafseedling culturing method is adopted for vegetative propagation, excellent characteristics of mother Camellia oleifera trees can be maintained, stable inheritance and a high differentiation speed areachieved, and the survival rate of the cultured seedlings is 93.5% or above.

Description

technical field [0001] The invention belongs to the technical field of camellia oleifera planting, and in particular relates to a method for growing seedlings of camellia oleifera. Background technique [0002] Camellia oleifera, belonging to the family Theaceae, is an evergreen small and medium-sized tree, also known as tea seed tree, camellia oil tree, and white flower tea. Camellia oleifera fruit can be squeezed into camellia oil for consumption. Camellia oil has a clear and fragrant taste, rich nutrition and storage resistance. It is a kind of high-quality edible oil and can also be used as lubricating oil and anti-rust oil. Camellia oleifera is one of the four major woody oil plants in the world. It grows in the mountains and hills in the subtropical regions of southern my country. It is a unique pure natural high-grade oil plant in my country. [0003] At present, the seedling raising methods of Camellia oleifera mainly include sowing seedlings, cutting seedlings, and...

AI Technical Summary

Problems solved by technology

[0003] At present, the seedling raising methods of camellia oleifera mainly include sowing seedlings, cutting seedlings, and leaf cutting seedlings. Among them, sowing seedlings needs to consume a large number of Camellia oleifera seeds, and are prone to genetic variation. Cutting seedlings can maintain the excellent traits of the female parent, but the amount of ears used is too large. It affects the output of the mother oil tea tree in the same year, and leaf cutting seedlings have the advantages of stable genetics, can reduce the transpiration of the mother tree, and do not affect the yield of the mother tree. However, the current technology of leaf cutting seedlings is not mature enough, and the survival rate can only reach about 80%. , slow differentiation and rooting
