Embodiment 1

[0043] 1) Selection of seedlings: select protocorms that have been cultured for 3 months.

[0044] 2) Selection of metasequoia forest land: choose the artificial metasequoia forest in Jiangsu Baoying Lake National Wetland Park, which is rich in humus layer.

[0045] 3) Forest land consolidation: plow outside the diameter of the Metasequoia trunk 1.5 times to break up the soil clods; set up drainage ditches according to the height of the woodland and the direction of water flow.

[0046] 4) Forest land fertilization: Apply 50-60 kg of base fertilizer per mu, which consists of 60% decomposed manure by weight, 25% fermented rapeseed cake, 5% silkworm excrement and 10% compound fertilizer.

[0047] 5) Planting under the forest: Sow the tissue-cultured protocorms directly, and cover with a small amount of soil rich in humus layer, and pour enough root-fixing water after planting.

[0048] 6) Forest land management: In the first year of tissue culture protocorms, add protocorm spec...

Embodiment 2

[0052] 1) Selection of seedlings: Select direct seeding domesticated seedlings.

[0053] 2) Selection of metasequoia forest land: choose the artificial metasequoia forest in Jiangsu Baoying Lake National Wetland Park, which is rich in humus layer.

[0054] 3) Forest land consolidation: plow outside the diameter of the Metasequoia trunk 1.5 times to break up the soil clods; set up drainage ditches according to the height of the woodland and the direction of water flow.

[0055] 4) Forest land fertilization: Apply 50-60 kg of base fertilizer per mu, which consists of 60% decomposed manure by weight, 25% fermented rapeseed cake, 5% silkworm excrement and 10% compound fertilizer.

[0056] 5) Under-forest planting: Live-directed domesticated seedlings are planted at intervals of 20-30 cm, and the planting depth is 5-8 cm. After planting, pour enough water for rooting.

[0057] 6) Forest land management: 50-60 kg of live-directed domesticated seedlings are topdressed 3-4 times a ye...

Embodiment 3

[0061] 1) Selection of seedlings: select domesticated seedlings for tissue culture.

[0062] 2) Selection of metasequoia forest land: choose the artificial metasequoia forest in Jiangsu Baoying Lake National Wetland Park, which is rich in humus layer.

[0063] 3) Forest land consolidation: plow outside the diameter of the Metasequoia trunk 1.5 times to break up the soil clods; set up drainage ditches according to the height of the woodland and the direction of water flow.

[0064] 4) Forest land fertilization: Apply 50-60 kg of base fertilizer per mu, which consists of 60% decomposed manure by weight, 25% fermented rapeseed cake, 5% silkworm excrement and 10% compound fertilizer.

[0065] 5) Under-forest planting: Tissue-cultured domesticated seedlings are planted at intervals of 20-30 cm, and the depth of planting is 5-8 cm. After planting, water enough root-fixing water.

[0066] 6) Forest land management: Tissue culture and domesticated seedlings are topdressed 50-60 kg 3-...

Abstract

The invention discloses a technology for efficiently planting bletilla striata (Thunb.) Rchb. F. under a metasequoia forest. The technology comprises the following steps of selection of seedlings, selection of the metasequoia forest, forest trimming, forest fertilization, under-forest planting, forest management, overwintering of bletilla striata (Thunb.) Rchb. F. and the like. The technology is suitable for domesticated seedlings and tissue culture protocorms, and a special fertilization scheme for topdressing of special foliage fertilizer is put forward for the protocorms. The method is adopted for seed selection of the protocorms, the survival rate can reach 90-95% or above, the seedling growing period is shorter than that of tissue culture domesticated seedlings and direct-sowing domesticated seedlings, and the growth period is shortened. Through seed selection of the tissue culture domesticated seedlings and direct-sowing domesticated seedlings, the survival rate can reach 96-100%, the bletilla striata (Thunb.) Rchb. F. grows vigorously and is high in yield, and the conventional management cost is significantly reduced relative to that of greenhouse planting and field planting. Besides, the promotion effect of the growth habit of metasequoia on the growth of the bletilla striata (Thunb.) Rchb. F. is proved by means of the technology. The technology is simple and feasible,and the resource utilization rate and the forest output rate can be increased.

Description

technical field [0001] The invention belongs to the field of plant planting, and in particular relates to a technical system for high-efficiency planting whitening under a metasequoia forest, so as to improve resource utilization rate and forest land output rate. Background technique [0002] White and ( Bletilla striata (Thunb.) Rchb. F.) also known as Bletilla striata, is also an important Chinese medicinal material in my country. Its dry tubers are recorded in the "Pharmacopoeia of the People's Republic of China". It is mainly used to treat hemoptysis, hematemesis, traumatic bleeding, sores and swelling, chapped skin, etc. In recent years, based on techniques such as tissue culture, live broadcasting, and root division, germplasm resources of Baiji have been widely used in artificial cultivation to provide raw materials for food processing, biomedicine, and natural daily chemical fields. It is also a drug with good market application potential with plants. The white an...
