Embodiment 1

[0030] The economic forest with a canopy density of 0.3 is selected as the forest land, and the soil quality is loose and fertile sandy soil with good drainage.

[0031] Spread the crushed straw and rice husk evenly in the woodland with a thickness of 5cm, and then use a small tractor to plow it to a depth of 30cm. It is fermented by mixing sheep manure and silkworm excrement at a weight ratio of 1:1 per mu. 600kg of organic fertilizer, and then plow the ground to mix the soil, straw, rice husk and organic fertilizer evenly, and the plowing depth is 40cm.

[0032] Three months later, when the above-mentioned three kinds of organic matter are retting, shallow plowing is performed once again, the plowing depth is 20cm, and the hardened seedlings are transplanted into the greenhouse for domestication for 2 months. The diameter of the original corm is greater than 0.5cm, and the seedling height is 3cm. Above, the Bletilla striata seedlings with a stem diameter of about 0.2 cm are ...

Embodiment 2

[0037] The economic forest with a canopy density of 0.5 is selected as the forest land, and the soil is loose and fertile sandy soil with good drainage.

[0038] Spread crushed soybean stalks and rice husks evenly in the woodland, with a thickness of 8cm, and then plow with a small tractor to a depth of 30cm. Apply sheep manure and silkworm excrement mixed and fermented at a weight ratio of 1:1 per acre. 800kg of organic fertilizer, and then turn the ground to mix the soil, soybean stalks, rice husks and organic fertilizer evenly, and the plowing depth is 30cm.

[0039] Three months later, when the above-mentioned three kinds of organic matter are retting, shallow plowing is performed once again, the plowing depth is 20cm, and the hardened seedlings are transplanted into the greenhouse for domestication for 2 months. The diameter of the original corm is greater than 0.5cm, and the seedling height is 3cm. Above, the Bletilla striata seedlings with a stem diameter of about 0.2 c...

Embodiment 3

[0044] The forest land is an economic forest with a canopy density of 0.7, and the soil is loose and fertile sandy soil with good drainage.

[0045] Scatter the crushed corn stalks and rice husks evenly in the woodland with a thickness of 6cm, then plow with a small tractor to a depth of 30cm, apply 800kg of fermented sheep manure per mu, and then turn the ground to make the soil, soybean stalks, rice Shells and organic fertilizer are mixed evenly, and the plowing depth is 40cm.

[0046] Three months later, when the above-mentioned three kinds of organic matter are retting, shallow plowing is performed once again, the plowing depth is 20cm, and the hardened seedlings are transplanted into the greenhouse for domestication for 2 months. The diameter of the original corm is greater than 0.5cm, and the seedling height is 3cm. Above, the Bletilla striata seedlings with a stem diameter of about 0.2 cm are transplanted into the woodland, and the seedling pits with a depth of 3 to 5 c...

Abstract

The invention discloses a bletilla striata cultivation method which is composed of forest land selection, land preparation, transplantation and cultivation management and the like. Compared with the prior art, according to the bletilla striata cultivation method, the under-forest space can be utilized effectively, the planting cost is reduced, the forest land unit area earning is improved, the planting cycle can be shortened, and bletilla striata quality and yield are improved. By utilizing cultivated seedlings of bletilla striata, the shortcomings that the tuber reproductive cycle is long, the reproductive efficiency is low, the seed consumption amount is large, the planting cost is high and plenty of artificial cultivation cannot be met easily can be overcome effectively. In addition, according to the method, agricultural straw and rice husk return to fields, not only can the environmental pollution caused by straw incineration be avoided, but also the soil structure can be changed, the soil fertility is improved, and the damage to the ecological environment caused by the use of chemical fertilizer is avoided.

Description

technical field [0001] The invention belongs to the technical field of cultivation of traditional Chinese medicinal materials, and in particular relates to a cultivation method of bletilla striata. Background technique [0002] Bletilla striata, also known as Baiji, Lianjicao, dry root, purple orchid, etc., is a perennial herbaceous bulbous plant of Orchidaceae. It grows in the evergreen broad-leaved forest at an altitude of 100-3200m. It likes a warm and humid habitat and is slightly cold-tolerant. . Mainly distributed in Shaanxi, Jiangsu, Guizhou, Guangxi, Sichuan, Zhejiang and other provinces. Bletilla striata is a kind of precious Chinese herbal medicine. Its tubers are used as medicine. It contains bletilla striata polysaccharides, bibenzyls, dihydrophenanthrenes and phenanthrene compounds. Chapped skin, water and fire burns, etc. [0003] Bletilla striata seeds are small and difficult to germinate in nature. Coupled with artificial over-harvesting and habitat destru...
