Breeding method of Chinese black olive cutting seedlings

Abstract

The invention discloses a breeding method of Chinese black olive cutting seedlings. The breeding method comprises the following steps that 1, newly growing-out twigs of more than 10 years old are selected as cutting collection objects; 2, cuttings are processed, the collected cuttings are soaked in a nutrient solution for 30 minutes after being disinfected with a mercury bichloride solution, thenare dried in the shade and are stored at the temperature of 4-5 DEG C; 3, the cuttings are taken out during cuttage, are placed at the temperature of 25-30 DEG C for 2 hours and then are put in a dormancy breaking solution for 1 hour; 4, a cutting seedling matrix is prepared; 5, the cuttings subjected to dormancy breakage is inserted into the cutting seedling matrix; 6, water and fertilizer management and disease prevention are conducted on the cuttings, and transplantation with soil is performed when the number of roots of each cutting is more than 10 and the average root length is greater than 7 cm. The problem is solved by adopting the method that at present, no mature Chinese black olive breeding method is provided and large-range popularization is difficult. The cutting breeding method makes the survival rate reach 90% or above, makes the survival rate of transplantation after outplanting reach 86% or above and has the great value for continuation of precious species.

Description

technical field [0001] The invention belongs to the field of plant breeding, and in particular relates to a method for cultivating black olive tree cutting seedlings. Background technique [0002] Black olive (scientific name: Canarium pimela Leenh.) Trees, up to 20 m in height, 45 cm in diameter at breast height. The fruit can be eaten raw, and the pulp is marinated as "Lanjiao" (or "Lanchi") for cooking. Terminalia is a good ingredient for cakes and dishes; the seed oil is used for food, soap making or other industrial oils. The wood is grayish-yellow brown, and the material is quite solid. It is used for the same purpose as olives. The root is used as medicine, which can cure rheumatism, low back pain, numbness in hands and feet, stomach pain, and burns. Black olive has important medicinal value and economic value: Medicinal value: [Zhuang medicine] Asami: The bark is used for internal injury and vomiting blood "Guiyao Bian". Root (black olive root): sour, astringent...

AI Technical Summary

Problems solved by technology

[0003] The breeding of black olives is generally carried out by grafting in the second year after planting, but there are disadvantages such as low survival rate, poor heritability of good traits, weak tree vigor after survival, poor resistance to stress, and easy to suffer from pests and diseases.
