Embodiment 1

[0014] This embodiment of the present invention is implemented according to the following steps:

[0015] 1. Select the area near the water source or the area with high ambient air humidity throughout the year, choose fertile sandy loam fields without water accumulation; prepare the ground from February to March, the width of the compartment is 1.2m, and the height of the compartment is 20cm; pave a layer of thickness 10cm The substrate consists of 7 parts of fully fermented sawdust + 1 part of fully fermented broken pine bark + 1 part of decomposed sheep manure + 1 part of peat soil to build a good seedbed.

[0016] 2. Sowing: From March to June, from October to December, select white bulbs and tissue culture bulbs and wash them, cut off the stems and leaves and sow them directly on the seedbed. Water, just wet, not drenched.

[0017] 3. Shed setup and management: build a shed after sowing, pay attention to ventilation when the temperature is high, and add a layer of sun...

Embodiment 2

[0019] This embodiment of the present invention is implemented according to the following steps:

[0020] 1. Select the area near the water source or the area with high ambient air humidity throughout the year, choose fertile sandy loam fields without water accumulation; prepare the ground from February to March, the width of the compartment is 1.2m, and the height of the compartment is 30cm; lay a layer of thickness 10cm The substrate is composed of 7 parts of fully fermented sawdust + 1 part of fully fermented broken pine bark + 1 part of decomposed cow dung + 1 part of peat soil to build a good seedbed.

[0021] 2. Sowing: After cleaning the white and tissue-cultured bulbs from March to June, cut off the stems and leaves, and sow directly on the seedbed. The diameter of the bulbs should be more than 1cm, and then cover them with plant ash mixed with fine sand, spray water, and moisten. , can not be poured through.

Abstract

The invention discloses a one-step seedling forming method of bletilla striata tissue culture corm and substrate adopted by the one-step seedling forming method. The method comprises the following steps: selecting fertile sandy soil field where water is not accumulated to be used as seedling growing field, ensuring that the width of a seedbed compartment surface is 1.2m, the height is 20 to 30cm and the thickness of the substrate is 10cm, selecting and washing bletilla striata tissue culture corms and directly seeding the bletilla striata tissue culture corms on a seedbed, covering the seedbed with plant ash doped fine sandy soil, spraying water to the seedbed, controlling the wettability, constructing a field inserting shed, and covering the shed with a shading net. The substrate comprises seven parts of fully fermented saw powder, one part of fully fermented broken pine bark, one part of rotten sheep manure, and one part of peat soil. The method solves the problem of technical difficulty of bletilla striata tissue culture seedling land transplantation, realizes one-step seeding forming of bletilla striata tissue culture corm, avoids the process of hardening-seedling and domestication of tissue culture seedling, reduces the production cost, realizes the scale production of bletilla striata, and provides technical support for the manual development and utilization of rare and endangered medicinal plant bletilla striata and the effective protection of wild resources.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a method for acclimating and transplanting tissue-cultivated seedlings of rare and precious medicinal material Baiji and its seedling-raising substrate. Background technique [0002] The rare and precious medicinal material Baiji is the orchid plant Baiji ( Bletilla striata ) of dried tubers. Baiji is a small perennial herb. Due to its high medicinal value and continuous expansion of industrial uses, the market demand is increasing year by year. The market supply mainly depends on wild resources. At present, it is rare to have a planting base of more than 100 mu. The price has continued to rise by more than 100 times, reaching 500 yuan / kg. It is one of the very few rare medicinal materials that only increases in price and does not superimpose. Wild resources have been destructively excavated, and wild resources are endangered. They are listed as rare and endan...
