Wild cultivation imitation method for pollution-free dendrobium officinale and barrel-frame-type seedling bed device thereof

Abstract

The invention discloses a wild cultivation imitation method for pollution-free dendrobium officinale. The method comprises the steps that multiple sets of square white cooked plastic water barrels areput in the woodland one by one and are close to one another, and the upper edges of the water barrels are bent inwards and obliquely extend 5 centimeters downwards in the direction of 45 degrees; theinner sides of the obliquely-extending outer edges are coated with anhydrous cupric sulfate; three square wooden strips are evenly placed on each white cooked plastic water barrel at intervals; a plate-shaped square bamboo-woven board is flat placed on the three square wooden strips and laid as a seeding bed board, and three layers of planting mediums are fully placed on the seeding bed board; abottom-layer filtering layer with the thickness of 5 cm is laid by mixing pine bark with the size of 4 cm and seaweeds according to the ratio of 3:1, a middle layer with the thickness of 8 cm is laidby mixing pine bark with the size of 2 cm and seaweeds according to the ratio of 4:1, and an upper layer with the thickness of 2 cm is laid by mixing pine bark dust and seaweeds according to the ratioof 5:1; the white cooked plastic water barrels are filled with water, and seedlings subjected to seedling verification are planted on the mediums of a bamboo-woven seedling bed in March. By means ofthe method, the planting survival rate can be increased to 90% or above, and the harvesting cycle is shortened.

Description

technical field [0001] The invention belongs to the technical field of cultivation of Chinese herbal medicinal materials, and in particular relates to a method for imitating wild cultivation of non-pollution dendrobium officinale and a barrel-type seedbed device thereof. Background technique [0002] Dendrobium officinale has the reputation of "gold in medicine" and "life-saving celestial grass". It is currently a popular Chinese herbal medicine and has become an important pillar industry for the structural adjustment of agricultural industries in Guizhou Province. In recent years, the inventor has conducted several investigations and studies on the cultivation bases of Dendrobium in Guizhou Province, and found that the most troublesome problem encountered by farmers is the harm of molluscs such as snails and slugs, especially for some extensively managed Dendrobium bases, snails, slugs, etc. The harm almost caused the harvest. At present, chemical pesticide control is a co...

Problems solved by technology

The pesticides commonly used by farmers are metaldehyde powder or granules. The control effect is good at the initial stage, but after several times of application, the control effect decreases; there are also excessive use of pesticides in the way of application, and repeated use of a single pesticide during the growth period In some cases, there are even behaviors such as blind application of pesticides, resulting in unsatisfactory field control effects and serious environmental pollution.
