Embodiment Construction

[0013] The method of ramet propagation of Daming Mountain Orchid is mainly carried out according to the following steps: 1. Planting land: use sandy loam rich in humus, slightly acidic, 5.5≤pH value≤6.5, rich in iron , good drainage performance, sandy soil, which is conducive to the operation of pulling out ramets; 2. Weeding: level the land, surround the field, pour water, immerse the soil for 2-3 cm, and immerse for 7-8 days. The weeds and evil roots of the plant are all soaked and dead, and then drain the water until the water content is 25-30%. Cut and separate the sprouts of each strain, and each strain preserves 5 connected pseudobulbs; 4. Ditch the furrow with a distance of 20-25 cm and a depth of 5-6 cm. On, compacted, watered, sprayed with liquid nutrient foliar fertilizer, sprayed once every two days, after 15 days, the roots can be poured with fertilizer; 5. Regularly spray Bordeaux mixture and chlorothalonil to prevent gray mold, anthracnose, white silk Fungal dis...

Abstract

The invention relates to a division propagation method for platanthera damingshanica. The method mainly comprises the following steps that 1, subacid sandy soil rich in humus is adopted; 2, weeding iscarried out, wherein land is leveled, the surrounding of the land is enclosed, water is poured into the land, the soil is immersed for 2-3 cm, and the soil is immersed for 7-8 days; 3, platanthera damingshanica stock plants are dug out, all the stock plants with dense pseudobulbs can be divided, bud seedlings of the plants are separated through cutting by blades, and five connected pseudobulbs are kept on each plant; 4, ditching is carried out, the ditch distance ranges from 20 cm to 25 cm, the plants are placed, the ditches are filled, compacting and watering are carried out, and liquid nutrient leaf fertilizer is sprayed; 5, a Bordeaux mixture and chlorothalonil are sprayed at regular intervals, gray mold, anthracnose, southern blight and other fungi diseases are prevented, and andthiophanate methyl, carbendazim, Mancozeb, anthrax opponents and other agents can be applied for prevention and control; 6, pesticide, such as Supracide and omethoate can be sprayed at regular intervals to kill thrips, scale insects, mites and the like; 7, generated rust diseases are prevented, wherein 500-600-fold liquid of 65% dithane powder or copper-bearing fungicide is sprayed.
