Problems solved by technology

[0004] The purpose of the present invention is to provide a method for cultivating Polygonatum multiflora with limited roots under high-slope forests, which can solve the problems of low utilization efficiency of such woodlands, heavy cleaning workload, and water and fertilizer utilization in traditional understory ridge cultivation of Polygonatum multiflora. Low efficiency and serious soil-borne diseases affect the yield and quality of Polygonatum multiflora

preparation example Construction

[0042] The preparation method of the special cultivation medium for Chinese herbal medicines used (refer to ZL 201410228080.6):

[0043] 1) Preparation of the mother seed of the strain: take the waste bacteria sticks after cultivating shiitake mushrooms, black fungus, ganoderma and other wood-rot fungi, remove the plastic bag, and use it as the raw material of the strain after being broken; add 0.5-3% of the weight of the raw material of the strain Brown sugar, 3-10% wheat bran, 2-8% corn flour, 1-7% ammonium bicarbonate, 3-15% superphosphate, stir evenly in a blender and use it as a strain compound material; Trichoderma live spores powder (effective number of viable bacteria ≥ 10 9 cfu / g) and the strain compound material are fully mixed at a weight ratio of 1:1000-1500, covered with a white plastic film and fermented for 15-20 days to obtain the mother species of the strain; the fermentation conditions are: pH value 7-8, CO 2 The concentration is 0.5%, the cultivation temper...

Embodiment

[0048] A method for root-limited cultivation of Polygonatum multiflora under a high-slope forest, the specific steps of which are as follows:

[0049] 1) Seedling propagation:

[0050] a) Preparation of seeds and seedlings: From late October to early November, harvest berries with dark red or purple-black skin, stack and ferment the berries, rub and rinse them, and sort out plump and undamaged seeds. River sand is evenly mixed at a weight ratio of 1:3, and stored at 3-5°C for 2-3 months to keep the seeds moist; combine it with a special cultivation medium for Chinese herbal medicines at a rate of 500 kg / hm 2 ~750 kg / hm 2 ; Then sow in early January to mid-February, before sowing, pour the seedbed thoroughly with 30wt% ferrous sulfate solution or 0.3wt% potassium permanganate solution for disinfection, then adopt drill or broadcast; remove weeds in time, do To "remove the early, remove the small, and remove"; after more than 10% of the seedlings are unearthed, spray or water ...

Abstract

The invention discloses a root restriction cultivation method of polygonatum multiflorum L. under high-slope forests. The method comprises seven aspects of seedling reproduction, forest selection, soil preparation and placement of root control devices, seedling transplanting, under-forest management, prevention and control over diseases and insect pests, harvesting and primary processing; according to the method, forests such as mixed forests, bamboo forests and broad-leaved forests where slopes are greater than 25 degrees, and ridging and formation of rectangular pieces of land are not easilyconducted are mainly selected, seedlings or seed stems (bud heads face upward) are planted in the root control devices, and a base fertilizer prepared by adopting a special formula and a planting substrate special for traditional Chinese medicinal materials are applied for planting. By adopting the method of cultivation of the polygonatum multiflorum L. under the high-slope forests, the problemscan be solved that at present, the utilization efficiency of the forest type is low, the impurity removal workload is high, according to traditional under-forest ridging cultivation of the polygonatummultiflorum L., the water and fertilizer utilization efficiency is low, soil-borne diseases are severe, and the yield and quality of the polygonatum multiflorum L. can be influenced; effective components of the obtained medicinal materials are consistent in content, stable and reliable, and can meet the standards of the 'polygonatum multiflorum L.' item of the 2015-version 'Chinese pharmacopoeia', and the method has a good popularization prospect.

Description

technical field [0001] The invention belongs to the field of planting Chinese medicinal materials, and in particular relates to a method for cultivating Polygonatum polyflora with limited roots under a high-slope forest. Background technique [0002] There are the following four problems in the existing Polygonatum multiflora under-forest cultivation technology. First, high-slope forest land is not easy to ridge and cultivate Polygonatum multiflora, which leads to low utilization efficiency of this type of woodland; The workload is heavy and the planting cost is high; third, due to the cumulative effect of infection sources, the understory ridge cultivation or imitation wild cultivation leads to increasingly serious pests and diseases, which affects the yield and quality of Polygonatum multiflora; fourth, the understory ridge cultivation has more Polygonatum is easily affected by flood and site soil conditions, and its water and fertilizer use efficiency is low. [0003] Th...
