Description

Dendrobium officinale cultivation method for rooting and promoting germination by tying trees

Technical Field

The invention relates to a cultivation method of dendrobium officinale, in particular to a cultivation method for rooting and promoting germination of dendrobium officinale by binding trees.

Background

The existing planting method of the dendrobium officinale comprises the following steps: firstly, planting in a greenhouse. The method has the defects of high cost due to the requirement of greenhouse investment, seedbed investment, irrigation system investment, land investment and larger manual investment, high planting density and humidity in the greenhouse, high temperature, high possibility of breeding germs, excessive pesticide spraying, pesticide residue formation and low quality of the planted dendrobium officinale. Secondly, the existing wild-imitating dendrobium nobile cultivation is more typical of the wild-imitating dendrobium nobile cultivation appearing in scenic floods. In the scenic spot flood, a company or an individual firstly uses hormone to plant dendrobium in a greenhouse to be five to sixty centimeters or even eight to ninety centimeters long, then the dendrobium is tied to a tree for one or two months by a rope (generally a straw rope) together with a planted matrix (material), and then the dendrobium is harvested and sold. The actual method is the compound planting of greenhouse planting and wild-simulated planting, the quality of the obtained dendrobium is similar to that of the dendrobium planted in a greenhouse, but the substrate and labor cost are increased and the growth of the dendrobium is wasted for two months in the greenhouse planting cost. Thirdly, lichen seeds are paved on the stones. In fact, the lichens are bred firstly and then the dendrobium is planted, and the compound planting is also realized, because the natural lichens cannot be found at all when the dendrobium is planted in a large area. Therefore, the method is a high-cost planting method and cannot be used for large-scale planting. As for other planting methods such as placing or nailing the litchi trees on the litchi trees at the Liya , the method is not worthy of popularization, and the dendrobium cannot be well fixed or cannot be popularized due to higher cost. Therefore, how to overcome the defects of the prior art and provide a planting method with low planting cost and high quality of the planted dendrobium officinale is a problem to be solved urgently in the technical field of dendrobium officinale planting at present.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provides a cultivation method for rooting and promoting the germination of dendrobium officinale bound with trees, which overcomes the defects in the prior art, greatly reduces the investment cost, saves greenhouse investment, seedbed investment, irrigation system investment and land investment, and ensures that the cultivated dendrobium officinale has excellent quality.

The invention adopts the technical scheme for solving the technical problems that: the cultivation method for rooting and promoting the germination of the dendrobium officinale bound trees comprises the following steps:

step 1): selecting healthy, strong and disease and insect free; culturing herba Dendrobii seedling with stem and total length of 8-12cm for 2-3 years as new seedling, dividing the selected new seedling into several new seedlings, each new seedling contains 3-5 new seedlings;

step 2): selecting a healthy and disease-free broad-leaved tree with the diameter of 30-40cm and a humid growing environment and a high air humidity as a cultivation tree;

step 3): fixing a plurality of secondary seedlings in the step 1) on the surfaces of a plurality of strips of linen with the width of 10-11cm at intervals, fixing the roots of the secondary seedlings by fixing strips, and keeping the root systems spread, wherein the distance between each secondary seedling and each secondary seedling is 10-12 cm;

step 4): folding a 30cm wide cloth strip in the middle, fixing the cloth strip at a position 0.5-1cm away from the edge of the opening by using a sewing machine to form a sleeve, and sequentially filling water absorbing materials into the sleeve to form a water absorbing layer;
