Embodiment 1

[0026] 1. Process the live white and the substrate and put it on a plate

[0027] Dry the first-year direct-seeded white and the substrate after drying, pass through a 20-mesh sieve, and then mix the sieved substrate with fermented bark powder (provided by Shaanxi Qinfeng Agrochemical Company) at a volume ratio of 5:1 , then the resulting mixture and carbendazim are mixed evenly in a volume ratio of 1000:5, and are mixed with the direct-broadcasting substrate of Dendrobium candidum, and the direct-broadcasting substrate of Dendrobium candidum is packed into a rectangular plate (made by Provided by Zhejiang Taizhou Yiyuan Agricultural Products Factory), the size of the rectangular plate is 54cm×27cm×6cm, installed to 2 / 3 of the depth of the rectangular plate, flattened and compacted, and then placed in the plastic greenhouse (for the convenience of operation, the height of the seedbed is 1m, the width is 2m, and every 2m along the length direction of the seedbed is set with a c...

Embodiment 2

[0038] In step 1 of processing the direct seed white and the substrate after the present embodiment, the substrate after the first year direct seed white is dried and passed through a 20-mesh sieve, and then the substrate after the sieving is mixed with the fermented bark powder (provided by Shaanxi Qinfeng Agrochemical Co., Ltd.) mix uniformly by volume ratio 10:1, then mix the gained mixture and carbendazim uniformly by volume ratio of 1000:5, and prepare Dendrobium officinale direct seeding matrix, other steps and embodiment 1 same. The plant picture of Dendrobium officinale 120 days after sowing is shown in Figure 4 .

Embodiment 3

[0040] In the present embodiment, the substrate of the first year's direct-seeding white rice is a mixture of fermented bark powder, nutrient soil, and river sand in a volume ratio of 1:8:1 and carbendazim in a volume ratio of 1000:1. For details, see the description of Example 2 in CN103404341B. Other steps are the same as in Example 1, and the plant diagram after sowing Dendrobium officinale seeds for 120 days is shown in Figure 5 .

Abstract

The invention discloses a method for recycling rhizoma bletillae nursing media and directly seeding dendrobium officinale. Media obtained after the rhizoma bletillae is directly seeded the first year are dried, sieved and then evenly mixed with fermented bark powder and carbendazim, then direct seeding media of the dendrobium officinale are prepared, and the dendrobium officinale is directly seeded through the media, so that the rhizoma bletillae nursing media are recycled, and the defect that the media can not be recycled after the rhizoma bletillae is directly seeded is overcome. The method is easy to implement, low in cost, high in speed of emergence of seedlings, low in dependence on seasons and territories, convenient to popularize and capable of completely meeting the requirement for large-area and large-scale seedling cultivation. The method overcomes the shortcoming that as dendrobium officinale seeds do not have endosperm, sprouting of the dendrobium officinale seeds is difficult under natural conditions, and a new path is developed for rapid propagation of dendrobium plants.

Description

technical field [0001] The invention belongs to the technical field of artificial planting of medicinal plants, and in particular relates to an artificial planting method of dendrobium officinale. Background technique [0002] Dendrobium officinale (Dendrobium officinale) is a perennial herb of the genus Dendrobium in the family Orchidaceae. As a traditional precious Chinese medicine, it is listed among the "Nine Immortal Grasses of China" because of its functions of nourishing the stomach and promoting body fluid, nourishing yin and clearing heat, moistening the lungs and relieving cough. First, it is the 2010 edition of Pharmacopoeia. [0003] The seeds of Dendrobium officinale are extremely small, without endosperm, low germination rate, low reproduction rate, slow growth, and harsh requirements on the growth environment (under natural conditions, it mainly grows on cliffs and rotten wood), and the natural yield is extremely rare. Under traditional conditions, propagatio...
