Insect controlling method of dendrobium officinale

Abstract

The invention provides an insect controlling method of dendrobium officinale and belongs to the technical field of disease and plague control of plant cultivation. The method comprises steps as follows: selection of tissue culture seedlings, preparation of an insect controlling and seedling hardening substrate, preparation of insect controlling fertilizer, field planting and management after field planting, wherein the insect controlling and seedling hardening substrate is prepared from peanut shells, broken saw dust and broken stone through mixing; the insect controlling and seedling hardening substrate is prepared with a method comprising steps as follows: the broken saw dust and the broken stone are proportionally mixed and uniformly stirred to form a mixture, before mixing, the peanut shells, vesuvianite and the broken saw dust are put in liquid medicine at the temperature of 100 DEG C for cooking and then are fished out and dried, the dried materials are cooked and then are fished out and dried, and the operation is repeated 3-4 times. The raw materials of the insect controlling and seedling hardening substrate are simple and available, chemical fertilizer is not required to be applied, the insect controlling cost is low, the seedling hardening survival rate of the tissue culture seedlings reaches 97% or higher, the insect controlling and disease resisting effects are good, and besides, obtained domestication seedlings have well developed root systems, avoid pathogenic bacterium invasion, have strong and thick stems and thick and dark green leaves, and are high in adaptive capacity to environment and low in cost.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of plant cultivation and disease prevention and epidemic prevention, in particular to an insect prevention method for Dendrobium candidum. [0003] 【Background technique】 [0004] Dendrobium officinale, also known as black knotweed, belongs to the Angiosperm, Monocotyledon, Trinite, Orchidaceae, and Dendrobium genus. It is a precious Chinese medicinal material with high medicinal value and strong health care function. Dendrobium officinale is naturally wild on cliffs tens of meters high. Wild Dendrobium officinale has low natural reproduction ability, slow growth, and demanding environmental conditions. In recent years, due to the devastating mining of wild resources of Dendrobium officinale, the wild Dendrobium officinale is on the verge of extinction. At present, the state has listed Dendrobium officinale as a rare and endangered species under key protection. [0005] In recent years, Chinese technicians...

Problems solved by technology

Both of these two cultivation methods have their disadvantages: direct planting in greenhouses is likely to cause insect damage, especially underground pests and molluscs such as snails and slugs. In some mountainous areas, there are also ants. Once pests occur, chemical agents cannot completely eradicate them. Candidum candidum has pesticide residues while affecting the yield; direct planting can also cause poor drainage, cause rotten roots of Dendrobium candidum and induce disease; it is difficult to completely replace the substrate after a long period of direct planting, which is likely to cause continuous cropping-induced diseases

Greenhouse seedbed overhead container cultivation is extremely expensive, and the volume of the container limits the growth of Dendrobium officinale, resulting in relatively low input and output

Under the existing cultivation methods, the quality and food safety of artificially cultivated Dendrobium officinale cannot be guaranteed, and the production efficiency is low, which restricts the dev
