Problems solved by technology

The safflower tree is usually seeded to breed seedlings, but its capsules are easy to fall off after ripening, the seeds lose their vitality within 3 months, the germination rate is extremely low, and the germination rate in the field is only about 30%, and the offspring of seed breeding are prone to variation , the seedlings are uneven

Embodiment 1

[0027] A method of asexual and rapid propagation of safflower safflower, which selects mature safflower safflower trees with straight trunks, excellent robustness, and no pests and diseases after planting for 25 years as the mother tree for seed collection. Seed husks are rotten and washed with clean water to obtain seeds. Soak the seeds in hot water at 65°C, and continue to soak for 24 hours after cooling naturally, sow them on a clean wet sand bed, cover with fine sand with a thickness of 2cm, sprinkle with clean water, and cover with a shading net with a shading degree of 65%. Maintain proper humidity during this period. Plow and smash the ear-picking nursery, evenly sprinkle superphosphate 100Kg / mu, garbage disposal fertilizer 200Kg / mu, and stir evenly with the surface soil for seedling raising, and form a seedling raising bed with a width of 1m for use. When the seeds germinate and have 2 pairs of complete leaves, transplant the seedlings to the nursery bed and plant the...

Embodiment 2

[0032]A method of asexual and rapid propagation of safflower safflower, which selects mature safflower safflower trees with straight trunks, excellent robustness, and no pests and diseases after planting for 27 years as the mother tree for seed collection. Seed husks are rotten and washed with clean water to obtain seeds. Soak the seeds in hot water at 70°C, wait for natural cooling and continue to soak for 24 hours, sow them on a clean wet sand bed, cover with 2cm thick fine sand, sprinkle with clean water, and cover with a 70% shading net for shade. Maintain proper humidity during this period. Plow and smash the ear-picking nursery, evenly sprinkle 100Kg / mu of superphosphate and 200Kg / mu of garbage disposal fertilizer, stir evenly with the surface of the nursery, and form a nursery with a width of 1m for use. When the seeds germinate and have 2 pairs of complete leaves, transplant the seedlings to the nursery bed and plant them according to the row spacing of the seedlings ...

Seed husks are rotten and washed with clean water to obtain seeds. Soak the seeds in hot water at 70°C, wait for natural cooling and continue to soak for 24 hours, sow them on a clean wet sand bed, cover with fine sand with a thickness of 3 cm, sprinkle with clean water, and cover with a 75% shading net for shade. Maintain proper humidity during this period. Plow and smash the ear-picking nursery, evenly sprinkle 100Kg / mu of superphosphate and 300Kg / mu of garbage disposal fertilizer, stir evenly with the surface of the nursery, and form a nursery with a width of 1m for use. When the seeds germinate and have 2 pairs of complete leaves, transplant the seedlings to the nursery bed and plant them according to the row spacing of the seedlings...

Abstract

The invention discloses a method for asexually and rapidly propagating homalium hainanense. The method includes working procedures for collecting seeds, constructing cutting orchards, managing mother plants, collecting shoots for cutting, performing cutting and managing cutting seedlings, and particularly includes selecting excellent and healthy mature trees without disease and pest injury to be used as mother trees for seed collection; collecting the seeds and conventionally accelerating germination of the seeds; transplanting sprouts of the seeds on seedling growing beds to culture seedlings and using the seedling growing beds as the cutting orchards; pruning tops of the seedlings to promote germination; cultivating totally-lignified branches to be used as the cutting scions; performing cutting on the scions in container cups filled with media; cultivating cutting seedlings to acquire the excellent and healthy cutting seedlings of the homalium hainanense. The method for asexually and rapidly propagating the homalium hainanense has the advantages that the homalium hainanense can be asexually propagated by means of cutting, so that the seedlings keep original excellent genetic characters of female parents, large quantities of seedlings can be neatly outputted from the orchards, the problem of shortage in improved varieties due to massive development of the homalium hainanense can be solved, afforestation development of the homalium hainanense can be accelerated, living requirements of people on furniture made of precious wood can be met, and the method has an important significance.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a method for rapid asexual propagation of safflower. Background technique [0002] Homalium hainanense, Homalium hainanense, is a large evergreen tree in the family Homalium hainanense. It is a precious timber tree species suitable for growing in the southwestern to eastern parts of China, especially Hainan Island. It has been introduced in other areas of Guangdong, Fujian, Guangxi and other places. It grows well, and most of the areas have blossomed and fruited. The safflower is an evergreen broad-leaved tree. The tree has a beautiful body and a straight trunk. It is an excellent greening tree species suitable for planting "all around". It is slightly shade-tolerant when young, and large trees need strong light. The wood is reddish-brown, with straight texture, tough wood, dense texture and toughness. It is used for shipbuilding, bridges, pillows, furniture, hydraulic ...
