Efficient interplanting method of bletilla striata and perilla frutescens

Abstract

The invention discloses an efficient planting method of bletilla striata and perilla frutescens. The method comprises the steps as follows: the bletilla striata is interplanted under crude medicines of honeysuckle and the like and covered with decayed livestock manure and grass, and harvest is achieved after about five-year plantation through management of procedures such as fertilization, weeding, insecticide and the like. According to the production method, two types of crude medicines are simultaneously produced in the same land, so that the cropping index is improved; and the labor cost is saved, the production cost is reduced, the output is increased, and economic benefits are doubled.

Description

technical field [0001] The invention relates to a high-efficiency interplanting method of bletilla striata and perilla, belonging to the technical field of modern Chinese herbal medicine cultivation. Background technique [0002] Bletilla striata, also known as Baiji and Ruolan, is a species of Orchidaceae, and its Latin name is Bletilla striata . Perennial herb, pseudobulb tuberous, white, plump, with finger-like divergences. The stem is stout, erect, 30-60 cm high. 3-6 leaves, lanceolate or broadly lanceolate, apex acuminate, base sheath-like clasping. Raceme terminal, sparse, with 3-8 flowers, large and beautiful, purple-red. Petals 3, labial obovate-oblong, deeply 3-lobed, middle lobe with wavy teeth, side lobes partially covering stamen; sepals 3, petal-shaped. Capsule, terete, above, with 6 longitudinal ribs prominent. The seeds are as small as dust. The flowering period is from late April to late May, and the fruit ripening period is mid-to-late November. Ther...

Problems solved by technology

[0009] Due to the large wild output of Bletilla striata, but in recent years, local governments have implemented the policy of returning farmland to forests, and the forests have recovered rapidly. Mountain forests or shrubs directly affect the lighting of Bletilla striata during the emergence stage, resulting in slow growth of Bletilla striata. In addition, the demand for Bletilla striata is strong. In the main production areas of bletilla striata, artificial planting has not yet been carried out, and the price of bletilla striata has risen from 30 yuan / kg to 380 yuan / kg now

Although there is a patent report on the interplanting technology of honeysuckle and bletilla striata, the existing problems of artificial planting of bletilla striata have been discussed, such as low planting yield and low benefit, which have partially solved the cultivation problem of bletilla striata, but due to the tree shape of about 1 meter honeysuckle on bletilla striata There are also certain problems in the growth of bletilla striata: for example, it partially affects the lighting of bletilla striata, tramples on bletilla striata during the four-time picking process of honeysuckle, and honeysuckle needs to be replenished after picking, which has a great impact on the expansion of bletilla striata in the later stage of bletilla striata. The expansion period is not synchronized with the honeysuckle picking period

[0010] To sum up, the interplanting technology of Bletilla striata and other plants is still immature, and there is no method suitable for large-scale production, and there is no fundamental solution to the short growth period of Bletilla striata, short rhizome growth period, low yield, and difficult harvesting. , high labor costs, serious pest damage and other key technologies
