Drip irrigation method for planting tree-planted dendrobium nobile

Abstract

The invention discloses a drip irrigation method for planting tree-planted dendrobium officinale. According to the drip irrigation method, during the planting of the tree-planted dendrobium officinale, a water storage device of a drip irrigation device is hung on a planting tree trunk. After that, a flow guide capillary tube is led out of the water storage device. The planting water in the water storage device is continuously led out to the tree foundation at the planting position of the dendrobium officinale by connecting a constant-flow needle with the flow guide capillary tube. According tothe method, the drip irrigation method is adopted. During the planting of the tree-planted dendrobium officinale, the root system of the dendrobium officinale is induced to be effectively combined with the tree body (effective parasitism) through keeping the tree bark to be moist. The survival rate and the yield of the dendrobium officinale are improved. In addition, due to the adoption of the drip irrigation method, the tree body does not need to be damaged during the planting of the tree-planted dendrobium officinale. The health of the planting tree body is not threatened at all. The mutualistic symbiosis of the tree-planted dendrobium officinale and the economic forest is realized. The economic value of the forest land in the unit planting area is effectively improved.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a drip irrigation method for planting Dendrobium dendrobii. Background technique [0002] Dendrobium, as a famous traditional medicine, has been regarded as a treasure for nourishing yin and tonifying since ancient times, especially Dendrobium candidum is known as "the first of the nine Chinese immortal herbs". At present, the resources of wild Dendrobium officinale are becoming increasingly depleted, and the mining of wild medicinal species that has been listed as a key protected species by the state is prohibited. However, the demand in the entire Dendrobium candidum market has increased, and the market supply is seriously in short supply. According to the statistics of the national traditional Chinese medicine resources survey, the total annual demand of the entire Dendrobium candidum market is 8,000 to 10,000 tons, and the annual demand increases by 10%-15%. The ...

According to the statistics of the national traditional Chinese medicine resources survey, the total annual demand of the entire Dendrobium candidum market is 8,000 to 10,000 tons, and the annual demand increases by 10%-15%. The market supply is seriously in short supply. It is estimated that the output of Dendrobium candidum will be difficult to meet within 10 years. need

[0003] The current cultivation of Dendrobium officinale in China mainly adopts greenhouse cultivation, which requires a large investment and occupies arable land; especially the high incidence of diseases and insect pests in greenhouse cultivation, the use of pesticides is inevitable, which will inevitably cause pesticide residues and heavy metals to exceed the standard, bringing great safety hazards to consumers. product is impossible

In recent years, with the continuous development of science and technology, the planting method of Dendrobium candidum has gradually become popular, which has effectively improved the pesticide residue problem of Dendrobium candidum in greenhouses, and improved the quality of artificially cultivated Dendrobium candidum; During the planting process, the low survival rate of Dendrobium candidum was highlighted
