Problems solved by technology

Now, the demand for bletilla striata is very strong in the market. In addition, in recent years, wild bletilla striata has been excessively excavated in most areas of my country, resulting in a sharp decrease in its natural resources. It is on the verge of extinction and has been listed as a key protected wild plant by the state. One, it can be seen that the use of bletilla striata in medicine is relatively large
In recent years, the state has issued a series of measures to strengthen the protection, research and development, and rational use of traditional Chinese medicine resources, requiring that the protection and breeding of rare and endangered varieties and the standardization of planting Chinese medicinal materials be strengthened to promote the recovery and growth of resources. Therefore, many domestic agricultural The Academy of Sciences and the planting company cooperated in the artificial cultivation of Bletilla striata. Although Bletilla striata has low requirements on the growth environment and is easy to plant, the traditional planting method is short of planting technology, which makes the rhizome of Bletilla striata after harvest thin and slender, with many insect eyes and poor quality. , low yield, poor economic benefits, and in order to blindly increase the income, the growers use a lot of pesticides and chemical fertilizers in the process of planting. These pesticides will not only cause soil pollution, but also have a lot of pesticide residues in the stems. After eating, not only the purpose of curing the disease cannot be achieved, but also there is a potential threat of pathological changes, which seriously reduces the inherent efficacy of bletilla striata and the quality of bletilla striata

Embodiment 1

[0017] The specific steps of this embodiment are as follows

[0018] Land selection and land preparation: choose moist and fertile, strong water and fertility retention, loose texture, and neutral sandy soil. In winter, plow the plot for more than 30 cm, and then apply 3000 kg of decomposed farmyard manure per mu before planting as base fertilizer, and again Plow the ground to mix the soil and farmyard manure evenly, rake the soil finely, and then make a high border with a width of 100-150 cm and a height of 30-40 cm along the north-south direction of the plot, and open a planting ditch 10-20 cm deep;

[0019] Preparation of nutrient soil: choose orchid rhizobium or orchid mycorrhizal bacteria collected from the roots of wild bletilla striata, and isolate beneficial symbiotic bacteria after artificial cultivation. The beneficial symbiotic bacteria are blended with water and prepared to contain 2.8~ The symbiotic bacteria nutrient solution with 300 million active ingredient...

Embodiment 2

[0028] The concrete steps of this embodiment are as follows:

[0029] Land selection and land preparation: choose moist and fertile, strong water and fertility retention, loose texture, and neutral sandy soil, plow the plot for more than 30 cm in winter, and then apply 2500 kg of decomposed farmyard manure per acre as base fertilizer before planting, and again Plow the ground to mix the soil and farmyard manure evenly, rake the soil finely, and then make a high border with a width of 100-150 cm and a height of 30-40 cm along the north-south direction of the plot, and open a planting ditch 10-20 cm deep;

[0030] Preparation of nutrient soil: choose orchid rhizobium or orchid mycorrhizal bacteria collected from the roots of wild bletilla striata, and isolate beneficial symbiotic bacteria after artificial cultivation. The beneficial symbiotic bacteria are blended with water and prepared to contain 2.8~ The symbiotic bacteria nutrient solution with 300 million active ingredie...

Embodiment 3

[0039] The concrete steps of this embodiment are as follows:

[0040] Land selection and land preparation: choose moist and fertile, strong water and fertility retention, loose texture, and neutral sandy soil. In winter, plow the plot for more than 30 cm, and then apply 3000 kg of decomposed farmyard manure per mu before planting as base fertilizer, and again Plow the ground to mix the soil and farmyard manure evenly, rake the soil finely, and then make a high border with a width of 100-150 cm and a height of 30-40 cm along the north-south direction of the plot, and open a planting ditch 10-20 cm deep;

[0041] Preparation of nutrient soil: choose orchid rhizobium or orchid mycorrhizal bacteria collected from the roots of wild bletilla striata, and isolate beneficial symbiotic bacteria after artificial cultivation. The beneficial symbiotic bacteria are blended with water and prepared to contain 2.8~ The symbiotic bacteria nutrient solution with 300 million active ingredien...

Abstract

The invention discloses a high-yield cultivation method for pollution-free bletilla striata. According to the method, a beneficial symbiotic bacterium nutrient solution obtained after orchidaceae rhizobium or orchidaceae mycorrhizal fungi are subjected to artificial cultivation and separation and humus soil are subjected to propagation fermentation, then nutrient soil is prepared, and after the nutrient soil and soil in planting trenches are mixed, field transplantation of tissue culture seedlings is performed; then intertillage weeding, topdressing and reasonable insect prevention are performed in the growing period, and harvesting can be performed after two years of growth. The method has the advantages that due to combination of symbiotic bacteria and an ecological planting technology, generation of bletilla striata new roots and large tubers are promoted, and meanwhile EM pest preventing liquid is used so that disease and pest damage can be totally avoided; compared with a traditional planting method, the harvested bletilla striata is large in size and small in individual difference, superior products can be over 95%, the yield per mu is increased by 40-50%, and the method has good economic benefits, social benefits and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese herbal medicines, and in particular relates to a high-yield large-scale cultivation method for bletilla striata. Background technique [0002] Bletilla striata is a perennial herbaceous plant of the genus Bletilla striata in the family Orchidaceae, mainly distributed in Henan, Shanxi, Sichuan, Guizhou, Yunnan and other places in my country. Bletilla striata is used as a tuber, which is recorded in "Shen Nong's Herbal Classic". It has the effects of nourishing the lung, reducing swelling, promoting muscle growth, and stopping bleeding. and other symptoms, in addition, Bletilla striata has gorgeous flowers and is also a good landscape plant. Now, the demand for bletilla striata is very strong in the market. In addition, in recent years, wild bletilla striata has been excessively excavated in most areas of my country, resulting in a sharp decrease in its natural resources. It is on the verg...
