A kind of method of dendrobium candidum under plantation

Abstract

The invention relates to the technical field of agriculture, in particular to a method for planting dendrobium officinale under a forest. The method is characterized by including the specific steps of selecting epiphytic culture trunks, arranging irrigation devices, preparing dendrobium officinale seedlings, and transplanting dendrobium officinale seedlings. By means of the method for planting dendrobium officinale under a forest, 360-degree dead-corner-free irrigation is achieved for planting dendrobium officinale under a forest, the effect of increasing the yield is achieved, the input cost of irrigation is reduced, and the waste of water resources is reduced; the method is simple and easy to implement and can increase the emergence rate, the survival rate and the polysaccharide content of dendrobium officinale and ensure a larger tiller number, so that the quality of dendrobium officinale is improved, and obtained dendrobium officinale has high economic value.

Description

【Technical field】 [0001] The invention relates to the field of agricultural technology, in particular to a method for planting dendrobium officinale under forests. 【Background technique】 [0002] Dendrobium officinale, also known as black knot grass, is the stem of the perennial epiphytic herb Dendrobium officinale in the genus Dendrobium orchidaceae. It is named for its iron-green skin and is a precious wild medicinal plant. Born on the semi-shady rocks in the mountains at an altitude of 1600 meters, it likes warm and humid climates and semi-shady and semi-yang environments, and is not cold-resistant. Generally, they can withstand low temperatures of -5°C. Dendrobium can be divided into dozens of species such as yellow grass, nobile, horsewhip, etc. Dendrobium candidum is the best product of Dendrobium. Dendrobium candidum has unique medicinal value. Its stems are used as medicine. According to the "Chinese Pharmacopoeia", Dendrobium has the effects of nourishing the stom...

Problems solved by technology

[0003] In recent years, there are many planting methods, and the "greenhouse planting method" is widely used at present. This method is concentrated planting, easy to manage, high in output, and good in economic benefits. However, building a greenhouse scaffolding requires a large one-time investment cost. In the process, the growth environment conditions of Dendrobium must be strictly controlled to shorten its growth cycle, and the stems are thick and plump. Some farmers even over-use pesticides and fertilizers to increase production. The result of the synergy of various factors makes the production of Dendrobium officinale Although it is high, its internal quality is far worse than that of wild dendrobium, and its medical and health effects are also greatly reduced.

There are also under-forest planting methods. Currently, there are various irrigation methods for under-forest planting of Dendrobium officinale, but there are often phenomena such as insufficient irrigation, waste of water resources, and easy blockage of nozzles.

Because Dendrobium candidum is planted under the forest, when the trunk is straight and the tree is 360°circular, and the nozzles are used to irrigate, under normal circumstances, only one-third of the entire trunk can be sprayed. If each tree is equipped with three nozzles It will lead to high production costs and waste of water resources

If you don’t install so many nozzles, there will be dead spots in the irrigation, which will cause insufficient water in some Dendrobium officinale and affect the production in the long run.
