Problems solved by technology

[0017] Aiming at the problems that the seeds of Dendrobium candidum are very small and difficult to grow into seedlings, and the seedlings cultivated by various methods are difficult to survive in the transplanting process, the present invention provides a method for mechanized cultivation of seedlings and field cultivation using Dendrobium candidum seeds to solve the difficulty of transplanting and labor costs. Advanced problems, easier to achieve the purpose of imitating natural environment cultivation

Embodiment 1

[0042] Take 100kg of dried kudzu for crushing, wash with 300L of water, collect the water and residue, let the water stand for a period of time to obtain the upper layer and sediment; take half of the upper layer and add it to 70kg of residue, then add 70kg of tung tree shells and stir at 50°C Soak for 10 hours, filter to obtain the filter residue and filtrate; after the filter residue is air-dried, conduct direct carbonization at 400°C to obtain activated carbon granules; add 25kg of tung dry cake, 12kg of potassium dihydrogen phosphate, and 10kg of potassium nitrate to 100L of filtrate, and then add 9kg of Bacillus subtilis powder Ferment for 24 hours, then add activated carbon particles to it, sterilize at 110°C for 20 minutes to obtain a suspension; add 25kg of precipitate to 120L of supernatant, gelatinize at 90°C for 30 minutes, add 20kg of acrylic acid, 3kg of catalyst and 4kg of cross-linking agent, and react at room temperature for 15 minutes Finally, 150L of reaction ...

Embodiment 2

[0044] Spray 2% carbendazim solution on the gel fertilizer granules to make the water content reach 250%, and make the surface of the gel fertilizer smooth; spread the Dendrobium officinale seeds evenly on the gel fertilizer, and germinate and cultivate them under the light intensity of 350LX After the dendrobium candidum seed turns green, the water content of the gel fertilizer is at 160%, and the gel fertilizer granules are directly sown on the surface of the dendrobium candidum substrate, the NAA aqueous solution 3L / m of 30mg / L every two days 2 The air humidity is 75-80% under the shade net condition, and the ambient temperature is 15°C-20°C to continue the cultivation. After the seedlings start to grow, water management and pest control are carried out according to conventional methods.

Abstract

The invention provides a dendrobium candidum gemmule seedling culture method which includes the steps: spraying 1-2.55 of carbendazim solution on gel fertilizer particles, enabling the content of the gel fertilizer particles to reach 200-250%, and enabling the surfaces of the gel fertilizer particles to be smooth; uniformly spreading dendrobium candidum seeds on gel fertilizers, and performing sprouting culture under 200-500LX illumination intensity; enabling the content of the gel fertilizers to reach 150-180%, directly spreading the dendrobium candidum seeds and the gel fertilizer particles on the surfaces of the dendrobium candidum media, spraying 2-4L / m<2> of 20-40mg / L NAA (naphthylacetic acid) water solution every three days after dendrobium candidum seeds turn green; continuing culture under a shade net and the air humidity of 75-85% at the environmental temperature of 15-25 DEG C, and performing water management and prevention and treatment of diseases and insects by a conventional method after young plants begin to grow. According to the method, starch materials are sufficiently converted into organic matters, active carbon is fixed in the gel fertilizer particles, and the loss possibility of organic fertilizers in the water spraying process is reduced.
