Cultivation method for promoting expansion of bletilla striata tubers and bletilla striata tubers cultivated therefrom

Abstract

The invention relates to a cultivation method capable of promoting expansion of bletilla striata tubers and the bletilla striata tubers cultivated through the cultivation method, and belongs to the field of bletilla striata planting. A drainage bottom layer prepared from at least one of pebbles and river sand is arranged in a planting ditch, a first net frame, a second net frame, a supporting part connected with the first net frame and the second net frame, and an isolating planting frame provided with a first reverse osmosis membrane and a second reverse osmosis membrane in a clamping mode are arranged on the drainage bottom layer, soil with the standard that 500 kg to 800 kg of base fertilizer is applied per mu is stacked in a stacking cavity of the first net frame, and a planting ridge is formed; after seeding tubers with at least two eyes are soaked in a tuber pretreatment agent including at least one of KH2PO4 with the mass percent of 3%-4%, sodium molybdate with the mass percent of 1.5%-3% and KNO3 with the mass percent of 3%-4% for 30-36 h, and sowing, field management and harvesting are carried out. According to the method, nutrients in the soil are effectively prevented from being lost, and expansion of the tubers is promoted.

Description

technical field [0001] The invention relates to the field of bletilla striata planting, and in particular to a cultivation method for promoting the expansion of bletilla striata tubers and bletilla striata tubers cultivated therefrom. Background technique [0002] Bletilla striata (scientific name: Bletilla striata), also known as Lianjicao, Gangen, Baigi, Zhulan, etc., is a perennial herb bulbous plant, which has good hemostasis, protection of gastric mucosa, antibacterial, anticancer, antiradiation and other drugs. Use value. However, with the increase in the dosage of bletilla striata, wild bletilla striata resources have decreased sharply, coupled with people's excessive excavation and predatory random harvesting, so that wild bletilla striata has become very few. Cultivation, using conventional cultivation methods, the bletilla striata planted is often the aerial part of bletilla striata grows luxuriantly and has a strong growth potential, but the underground tuber par...

Problems solved by technology

However, with the increase in the dosage of bletilla striata, wild bletilla striata resources have decreased sharply, coupled with people's excessive excavation and predatory random harvesting, so that wild bletilla striata has become very few. Cultivation, using conventional cultivation methods, the bletilla striata planted is often the aerial part of bletilla striata grows luxuriantly and has a strong growth potential, but the underground tuber part used for medicine grows very poorly. In order to enhance the growth of the underground tuber part, it is usually used to apply The mode of a large amount of fertilizer, this mode can promote the expansion of bletilla striata tuber to a certain extent, but causes the application amount of fertilizer to be big, has increased the cost of production, also can cause excess fertilizer to be enriched in soil simultaneously; And, through Applying a large amount of fertilizers makes the tubers of Bletilla striata expand, and the weight of the tubers of Bletilla striata does increase to some extent, but its medicinal effect is reduced, and it does not actually achieve the meaning of expanding the tubers of Bletilla striata
