Bletilla germchit propagation method

Abstract

The invention provides a bletilla germchit propagation method, belonging to the technical field of Chinese medical herb cultivation. The method consists of five steps of preparation of propagation field, preparation of protospecies, field planting propagation, seedbed management and germchit coming out of nursery, comprising the following steps: fertilizing 2-3kg of thoroughly decomposed farmyard manure, 50-55g of compound fertilizer and 15-17g of 80% soluble dipterex powder agent in the protected field to be evenly mixed with the soil; selecting the bletilla tuber having 3-5g of single tube with at least one hibernaculum as the protospecies; digging transversely shallow furrows with depth of 5-8cm on the border checks with the space between rows of 6-8cm*8-10cm, the seedbed soil humidity of 60-70%, and the room temperature of 15-20 DEG C; and covering a black lightproof net with the lightproof rate of 70-75% when the germchits coming out of the nursery. In the invention, the propagation period is one year earlier than the contrast and the average income of the germchits per mu can achieve * yuan. As the quality of the germchits is good, each mu can increase 100-240kg of production, thus increasing income.

Description

technical field

[0001] The invention relates to the technical field of cultivation of Chinese herbal medicines, in particular to a method for multiplying the seedlings of the herbal medicine. Background technique

[0002] White and (Bletilla striata), belongs to Orchidaceae, perennial herb. It is native to China and is widely distributed in southwest, southeast and most parts of North China. It grows in forests, valleys and rock crevices at an altitude of 1100m-3200m. It has strong resistance to shade. Slightly cold in nature, sweet and astringent in taste, it has the effects of astringent, hemostasis, detumescence and muscle growth. It is an important raw material of "Baiji Granules" in Chinese Pharmacopoeia.

[0003] In recent years, due to the prominent contradiction between natural resources and development and utilization of white and natural resources, artificial domestication and planting of white and is an effective way to alleviate the contradiction of resource sho...

Examples

Embodiment 1

[0021] Embodiment 1: Radix Radix Radix Radix and seedling propagation method of the present invention, carry out according to the following steps:

[0022] 1. Preparation for multiplication: Use loose and fertile soil as the soil for multiplication in the greenhouse protection area, and make a low-level plot. The width of the border is 1.2m, and the working path is 25cm. The border is 3cm lower than the working path. In conjunction with site preparation, apply 3kg of decomposed farmyard manure, 50g of compound fertilizer (the ratio of nitrogen, phosphorus and potassium is 12:15:15) and 15g of 80% soluble trichlorfon powder per square meter, and mix evenly with the soil;

[0023] 2. Preparing the original seed. Select a single tuber that weighs 3-5g, is full and plump, has no pests and diseases, has a well-developed root system, has at least one overwintering bud, and is uniform in size as the original seed. Preservation, the preservation time shall not exceed 48 hours;

Embodiment 2

[0031]Embodiment 2 and embodiment 3: embodiment 2 and embodiment 3 are also the embodiments of the Radix Radix Radix Radix Sinensis of the present invention, except that the measures listed in table 1 are different, all the other steps are the same as embodiment 1, no longer repeat.

Embodiment 4

[0032] Embodiment 4 contrast 1-tuber dicing direct planting

[0033] The specific method is as follows: divide a single white and tuber into 3-5 small pieces with a knife, and then directly sow the divided small pieces in the field as seedlings, smear the plant ash on the incision, and press the plant spacing 10-12cm, row spacing 12 -15cm drill, cover soil 3-4cm thick, harvest after three to four years.

[0034] Test results: the overwintering buds are small, the bud length is 1-2cm, and the diameter of the bud base is 0.1-0.3cm; the plant height is uneven, and the plant height is 5cm-30cm; the survival coefficient is as low as 65-70%; It can only be harvested after 3-4 years of production; the yield is low, and the weight of the original species is removed, and the new weight per mu per year is 120-150kg. The reproduction coefficient is 1:1-3 strains.
