Embodiment 1

[0063] Present embodiment provides a kind of Tibetan cypress seedling raising method, comprises the following steps:

[0064] (1) Seed collection

[0065] The collection site is Yigong, Tibet. From October to November, when the cones turn from green to brown and the cracks between the scales are obvious, it is the best time for seed collection. Before seed collection, it is necessary to select a plant that is strong in adulthood, has a good stem shape, and has no quarantine diseases as the mother tree for seed collection. Remember to pick cones that have grown on the main and large branches for many years without falling off, persist for a long time, and do not crack. The seeds are mostly empty and have no germination ability.

[0066] The collected cones are spread out in a ventilated and dry place, and after a little drying, the seed scales can be cracked, the cones are turned, and the seeds come out. Sieve the seeds, remove impurities and shriveled seeds, put them in clot...

Embodiment 2

[0086] Present embodiment provides a kind of Tibetan cypress seedling raising method, comprises the following steps:

[0087] (1) Seed collection

[0088] The collection site is Yigong, Tibet. From October to November, when the cones turn from green to brown and the cracks between the scales are obvious, it is the best time for seed collection. Before seed collection, it is necessary to select a plant that is strong in adulthood, has a good stem shape, and has no quarantine diseases as the mother tree for seed collection. Remember to pick cones that have grown on the main and large branches for many years without falling off, persist for a long time, and do not crack. The seeds are mostly empty and have no germination ability.

[0089] The collected cones are spread out in a ventilated and dry place, and after a little drying, the seed scales can be cracked, the cones are turned, and the seeds come out. Sieve the seeds, remove impurities and shriveled seeds, put them in clot...

Embodiment 3

[0109]Present embodiment provides a kind of Tibetan cypress seedling raising method, comprises the following steps:

[0110] (1) Seed collection

[0111] The collection site is Yigong, Tibet. From October to November, when the cones turn from green to brown and the cracks between the scales are obvious, it is the best time for seed collection. Before seed collection, it is necessary to select a plant that is strong in adulthood, has a good stem shape, and has no quarantine diseases as the mother tree for seed collection. Remember to pick cones that have grown on the main and large branches for many years without falling off, persist for a long time, and do not crack. The seeds are mostly empty and have no germination ability.

Abstract

The invention relates to the technical field of forest tree propagation, and in particular relates to a himalayan cypress germination accelerating composite and a preparation thereof and a seed sowing and seedling growing method of himalayan cypress. The himalayan cypress germination accelerating composite comprises IAA (Indole Acetic Acid), 6-BA (benayl aminopurine) and sodium nitroprusside. With the adoption of the himalayan cypress germination accelerating composite, the germination rate of himalayan cypress seeds can be obviously increased. According to the seed sowing and seedling growing method, the seed sowing and seedling growing are artificially performed through a greenhouse in a fine manner, so that a series of problems in a traditional seedling growing method can be overcome; the seedling rate is more than 85%; the uniformity is high; in addition, the seedlings grow well; the method has the characteristics that the seedling can grow quickly, the growing period is short, and the operation is simple; the problems in the himalayan cypress seed sowing and seedling growing process, such as low germination percentage of seeds, low seedling rate, weak seedlings, and seed sowing and seedling growing in spring, can be solved.

Description

technical field [0001] The invention relates to the technical field of tree propagation, in particular to a cypress germination accelerating composition and its preparation and a method for sowing and raising seedlings of Tibetan cypress. Background technique [0002] Tibetan cypress (Cupressus torulosa D.Don), also known as Himalayan cypress, is a national protected plant, an endangered species, a tall tree, 30-50m high, 1-3m diameter at breast height, and a crown width of 6m. The unique conifer species in the Himalayas are distributed in the southeastern part of Tibet at an altitude of 2000-2500m, specifically in Tongmai and Yigong in Bomi County and the line from Pailong, Tongdeng to Menzhong in Nyingchi County. Indonesia, Nepal, Bhutan, and Sikkim are also distributed. [0003] Tibetan cypress is a precious fast-growing timber tree species. The trunk is full and straight, the wood is light yellow, the texture is straight, the structure is fine, the material is hard, fra...
