Description

Combined suspension type dendrobium candidum under-forest planting structure and planting method

Technical Field

The invention relates to a combined suspension type dendrobium candidum under-forest planting structure and also relates to a planting method for planting according to the combined suspension type dendrobium candidum under-forest planting structure.

Background

Herba Dendrobii is a perennial grass plant of Orchidaceae, and has effects of nourishing yin and yang, cooling, moistening, and dredging air. Wild plants generally grow on the trunk of cliffs or tall trees in the back, are perennial herbaceous plants with very strict requirements on ecological environment, and have slow growth, low natural propagation rate and low natural yield.

Dendrobium nobile has extremely high value of traditional Chinese medicine, wherein Dendrobium officinale is a top-grade product in Dendrobium nobile. The chemical substance components such as water-soluble polysaccharide, alkaloid, amino acid, trace elements and the like contained in the dendrobium have certain efficacy in the aspects of enhancing immunity, resisting tumor, reducing blood sugar, protecting liver injury, easing pain, resisting inflammation, resisting aging and the like. Because all wild orchid plants are protected plants, the dendrobium candidum products sold in the market at present are planted manually.

At present, agricultural greenhouse facilities are mostly used in the manual cultivation of dendrobium candidum, but dendrobium candidum is planted in a greenhouse, so that the quality of finished dendrobium candidum products is easily reduced. Related researches show that compared with dendrobium candidum plants naturally grown in a wild environment, dendrobium candidum produced in an artificial planting environment does not show obvious difference in active ingredients, but has insufficient accumulation of effective dry matters and taste due to the difference of growth environments. Therefore, in order to obtain products with the quality similar to that of wild dendrobium candidum, the dendrobium candidum is planted in a forest land in many areas by simulating the natural growth environment of the dendrobium candidum. The method mainly comprises the steps of directly covering a proper arbor trunk with a binding planting matrix, then planting dendrobium candidum seedlings, or directly binding a planting bag filled with the planting matrix on the trunk.

The method for planting the dendrobium candidum on the tree trunk and the outer skin of the tree trunk in the woodland simulates the natural growth environment of the dendrobium candidum to a certain extent, so that the dendrobium candidum grown under the planting condition has the quality similar to that of the wild dendrobium candidum. There are also many problems:

1. the tree species has small choice and limited application degree in forest lands

Because dendrobium candidum is an orchid plant, the root systems of the plants are all fleshy root systems, independent roots and unnecessary roots, and the dendrobium candidum can be divided into thicker straight root-like stems and slender transverse root-like stems according to the forms. In the root growth process, the root needs to climb on the substrate. Therefore, when tree species are selected for field planting, arbor species with rough bark must be selected, which limits the possibility of planting under-forest dendrobium candidum on certain arbor species with smooth surfaces. Resulting in a low degree of application to the woodland.

2. The difficulty of pest and disease control is great

Because the dendrobium candidum under-forest planting mode is to directly fix the dendrobium candidum growing bag on the arbor trunk and directly contact with the bark, a channel is provided for the transmission of bacteria, viruses, pests and the like. And the controllability of the pest management under the forests is much unpredictable compared with the greenhouse environment. Therefore, the method has extremely high requirements for keeping the suitable under-forest natural optimal environment of the dendrobium candidum.

3. The optimal environment for natural growth of dendrobium candidum is not fully simulated

Dendrobium officinale is planted under the forest, and the most critical point is to create a continuous optimal growth environment. The most suitable growing environment of orchid is the environment of semi-yin and semi-yang, cool, moist and smooth air, and the condition is most suitable for the root system of orchid. Dendrobium officinale is planted under the forest, the semi-negative and semi-cool condition is easy to realize, but the matrix bag is tightly attached to the trunk of arbor, so that great difficulty exists in keeping cool, moist and smooth air in the matrix.

Compared with the prior art, the invention has the following beneficial effects:

1. the final goal of planting dendrobium candidum under the forest is to produce the dendrobium candidum product with the quality similar to that of natural environment growth. The best growing environment of the dendrobium candidum in a natural state is half-yin and half-yang, cool, moist and smooth in air. The best growing environment of the dendrobium candidum in a natural state is half-yin and half-yang, cool, moist and smooth in air. The most difficult problem of planting dendrobium candidum under the forest is to always keep the growth substrate where the root system of the dendrobium candidum is located cool, moist and smooth in air. In order to ensure that air in a growth substrate is kept smooth, a vertical blind hole, a bottom side hole and a side wall vent hole are arranged on a columnar wood block for attaching a growth substrate layer, and due to the thermal effect of the air, the air uniformly enters the vertical blind hole from bottom to top through the bottom side hole and then enters the growth substrate layer through the side wall vent hole. Meanwhile, the horizontal wood plates and the filling moss are arranged in the vertical blind holes, so that the air circulation speed can be restrained, and the air in the growth substrate layer is kept slowly updated at any time, so that the smoothness of the air in the growth substrate layer for growing dendrobium candidum is better kept.

2. The invention can better circulate tissue air, when air enters the vertical blind hole from the bottom side hole, the air can pass through the filling moss to enter the growth matrix layer from the side wall vent hole or be discharged from the side hole of the wood board on the horizontal wood board. In the process, flowing air is always fully contacted with the moss for filling, and because the moss has a good water storage function, the temperature of the circulated air can be reduced by contacting with liquid water, so that the cool and moist air discharged is ensured, and the growth substrate layer and the periphery of the planting assembly are effectively kept in a cool and moist microenvironment (an air flow schematic diagram is shown in fig. 11, and the direction shown by an arrow is the air circulation direction).

3. In order to prevent excessive moisture in the growth matrix layer from influencing the growth of dendrobium candidum, the invention adopts vertical arrangement when the whole arrangement is adopted, the growth matrix layer is designed to be a layer covered on the outer wall of the columnar wood block, when natural precipitation is encountered, liquid water exceeding the storage capacity of the growth matrix layer directly flows downwards due to the action of gravity, and the moisture content of the growth matrix layer cannot exceed the highest value excessively under the rainy season; in dry seasons, the materials used by the planting structure are organic hydrophilic materials such as log, coir rope and moss, so that the water retention performance is good, the moisture can be kept for a long time, moisture is provided for a growth substrate layer, and the influence of insufficient humidity in the air on the growth of dendrobium candidum is buffered. Thereby better maintaining proper moisture conditions.

4. According to the invention, a plurality of planting assemblies can be vertically connected in series, and when water is supplemented, water is supplemented to the planting assembly at the uppermost layer. When fully moisturizing is carried out to the planting subassembly at the uppermost layer, outside unnecessary moisture can down flow along the outer wall of column wood piece, and inside unnecessary moisture can down flow the discharge through perpendicular blind hole, connecting rope, bottom mesopore and bottom side opening, and in the planting subassembly of parallel flow below, automatic down flow can reduce the work load that the manual work watered, and can realize the high-efficient application of water, reduce the waste of water (as the water flow schematic diagram shown in fig. 12, the direction that the arrow shows is the water flow direction).

5. The lower surface of the columnar wood block can be provided with the inverted conical surface, so that the external water body can flow downwards more conveniently, and most of the external water body flows to the connecting rope along the inverted conical surface and then flows downwards along the connecting rope.

6. The existing dendrobium candidum planting technology is to cover and plant dendrobium candidum on arbor stems, firstly, arbor varieties with rough barks need to be selected, and selectable arbor varieties are limited; secondly, binding can only be carried out on trunks, the production capacity is greatly influenced by the tree diameters of the trees, the production scale is limited, and a large amount of understory empty lands cannot be applied. The application of the invention does not need to consider arbor varieties, and the invention can be hung and fixed on various supports below a tree forest or directly hung on branches, can be applied to the space under the forest, reduces the application limiting conditions for the planting of the dendrobium candidum under the subway forest, and enlarges the planting range of the dendrobium candidum under the forest in a large area.
