Medicinal anoectochilus formosan stem-cutting root-retaining regeneration planting method

Abstract

The invention discloses a method for regenerating and planting medicinal anoectochilus roxburghii with the stem removed but the root left, which has the key point of regeneration with the root left and stem removed. First, strong tissue culture seedling are elected and then transmitted to be planted in a mixed substrate consisting of soil, coarse sand and wood dust after plantlet hardening and watered with a mixed liquid of root agent and carbendazim wettable powder. Field management, fertilization and disease preventing and treating are required to be respected during the growth period of the anoectochilus roxburghii. By applying the method of regeneration with the stem removed and the stem left, the anoectochilus roxburghii stems on the ground are harvested but a stem node at each stem is left before the bolting and blossom of the anoectochilus roxburghii. After harvesting, the remained plant is sprayed with a mixed liquid of 6-benzyl aminopurine and carbendazim wettable powder. The method aims at solving the problem of narrow availability of the anoectochilus roxburghii seedling and easily sprouting of the stem node thereof and adopts the production method of regeneration with the stem removed and the stem left, thereby improving the seedling use ratio, guaranteeing the product supply and realizing continuous production. Meanwhile, the complete retaining of the root system creates the good condition for the quick growth of new sprouts and therefore, the regeneration method of the invention has comparatively high production efficiency and good economic benefit.

Description

technical field

[0001] The invention relates to a method for regenerating medicinal clematis by cutting stems and leaving roots, which is mainly used for the industrialized planting of medicinal clematis. Background technique

[0002] Anoectochilus roxburghii (wall.) lindl] is a perennial herb of the family Orchidaceae. It uses the whole herb as medicine. It is also known as golden silkworm, golden thread orchid, golden thread orchid, etc. It is a traditional and precious medicinal material in my country. "Golden grass", "miracle medicine", "black ginseng" and other laudatory names have a wide range of folk applications, and are widely used in the treatment of rheumatoid arthritis, high blood pressure, diabetes, kidney disease and other intractable diseases, as well as for strengthening the body and treating diseases. It is regarded as a rare and precious medicinal material especially in Zhejiang, Fujian, Taiwan and other provinces and Southeast Asia, especially in Taiwan Prov...

Embodiment 1

[0043] 1) Prepare the planting site. The base is about 620m above sea level, with sandy yellow loam soil, pH value 6.1, loose soil and good drainage. The greenhouse is made of wood and moso bamboo, with a width of 4m, a height of about 2.3m, and a length of 24m. It is covered with a layer of nylon film and a layer of shading net with a shading rate of 70%. There are two doors at each end. The substrate is improved by the ratio of one part of soil plus two parts of river sand with a diameter of about 3mm and one part of sawdust. Before the substrate is mixed, apply 45% nitrogen, phosphorus and potassium equivalent compound fertilizer as the base fertilizer according to the standard of 50kg per mu, and then mix well , make a furrow surface about 20cm high and 1.2m wide, the furrow surface is flat, 2 furrows are built in one greenhouse, and drainage ditches about 25cm deep and 50cm wide are opened around (also used as operation channels), the actual planting area is about 55m2 2...

[0051] 1) Prepare the planting site. The base is about 760m above sea level, with sandy yellow loam soil, pH value 6.3, loose soil and good drainage. The greenhouse is made of wood and moso bamboo, with a width of 2m, a height of about 2m, and a length of 16m. It is covered with a layer of nylon film and a layer of shading net with a shading rate of 70%. There are two doors at each end. The substrate is improved according to the ratio of one part of soil plus two parts of river sand with a diameter of about 2-3 mm and one part of sawdust. Before mixing the substrate, apply 45% nitrogen, phosphorus and potassium equivalent compound fertilizer as the base fertilizer according to the standard of 50 kg per mu. Mix well to make a furrow with a height of about 20cm and a width of about 1.2m. The furrow is flat.

The greenhouse is made of wood and moso bamboo, with a width of 4m, a height of about 2.2m, and a length of 30m. It is covered with a layer of nylon film and a layer of shading net with a shading rate of 70%. There are two doors at each end. The substrate is improved by the ratio of one part of soil plus two parts of river sand with a diameter of about 3mm and one part of sawdust. Before the substrate is mixed, apply 45% nitrogen, phosphorus and potassium equivalent compound fertilizer as the base fertilizer according to the standard of 50kg per mu, and then mix well , make a furrow surface with a height of about 20cm and a width of about 1.2m. The planting area is about 140m 2 .
