Embodiment 1

[0026] A seedling raising method of direct seeding dendrobium candidum, in which the seeds of dendrobium candidum are directly sown on moss, and the seed germination and emergence process of the dendrobium candidum seeds are completed in the moss; the moss grows on the moss growth matrix layer .

[0027] In this embodiment, the moss growth matrix layer is bark; the moss is moss on the bark. In other embodiments, the moss grows on a growth substrate layer consisting mainly of bark and sawdust.

[0028] The Dendrobium candidum seeds are directly sown on the moss, and the Dendrobium candidum seeds complete the seed germination and emergence process in the moss; specifically: the Dendrobium candidum seeds are configured into a seed suspension, and the seed suspension is evenly sprayed on the moss On the surface, manage the seedling stage so that the germination rate is higher than 50%. The seedling stage management is specifically as follows: within 30 days before spraying the s...

Embodiment 2

[0031] The invention discloses a direct seeding seedling raising method of dendrobium candidum. In the method, seeds of dendrobium candidum are directly sown on moss, and the seeds of dendrobium candidum complete seed germination and emergence in the moss.

[0032] In this embodiment, the moss growth substrate layer is soil; the pH of the soil is adjusted so that the pH of the soil is between 5-5.5, and the soil of this pH is suitable for the growth of moss.

[0033] The moss is artificially cultivated moss. The planting steps of the moss are as follows: put the block moss, milk and water together into a mixer for stirring to obtain a moss seed liquid; evenly sprinkle the moss seed liquid on the moss growth substrate layer to provide an environment suitable for moss growth Conditions (spraying every day, keep moist, 22-27 ℃, weak light), when the coverage rate of moss on the moss growth matrix layer is higher than 90%, it can be used as seedling of Dendrobium officinale. In t...

Abstract

The invention mainly belongs to the field of dendrobium officinale seedling growing and particularly relates to a seedling growing method and a cultivation method of direct-sowed dendrobium officinale. According to the seedling growing method and the cultivation method, dendrobium officinale seeds are directly sowed on moss, and seedling germination and seedling emergence processes of the dendrobium officinale seeds are completed on the moss; the moss grows on a moss growth substrate layer. According to the seedling growing method, the dendrobium officinale is subjected to direct-sowed type seedling growing, and the disadvantage of tissue-cultured seedling is avoided; according to the cultivation method, the seedlings obtained from the direct-sowed type seedling growing method are subjected to transplantation and cultivation with the moss and the moss growth substrate layer, and the survival rate of the dendrobium officinale can be improved in cultivating.

Description

technical field [0001] The invention mainly belongs to the field of seedling raising of dendrobium candidum, and in particular relates to a seedling raising method and a cultivation method of direct seeding dendrobium candidum. Background technique [0002] Dendrobium officinale Kimura et Migo (Dendrobium officinale Kimura et Migo) is a perennial epiphytic herb belonging to Dendrobium officinale and is one of the most precious Chinese herbal medicines in my country. Efficacy and a wide range of applications are gradually known. With the integration of planting technology, the planting industry of Dendrobium officinale has achieved large-scale and intensive development, and the planting area and output have increased year by year. [0003] The current propagation of Dendrobium officinale is mainly to obtain seedlings through plant tissue culture, and the cultivation process mainly uses tissue cultured seedlings as seedlings. Plant tissue culture, that is, plant aseptic cultu...
