Embodiment 1

[0030] In Baoying, Jiangsu, Dendrobium candidum is planted in the metasequoia forest, where snails, slugs and other reptiles can be found in the metasequoia forest, and the planting area near the base of the trunk has traces of Dendrobium candidum being eaten by snails, slugs and other reptiles. Treatment is carried out in accordance with the combinations and methods of the present invention. Specifically: prepare Baiji polysaccharide glue, apply the aqueous solution of Baiji polysaccharide glue to the 50cm area of ​​the base of Metasequoia tree, and reapply every three months to ensure the viscosity of Baiji polysaccharide glue. Compared with the control metasequoia in the same metasequoia forest, there were no traces of snails, slugs and other reptiles in the metasequoia coated with white and polysaccharide glue, while the dendrobium candidum in the control metasequoia showed signs of being eaten away.

Embodiment 2

[0032] In Baoying, Jiangsu Province, Dendrobium candidum is planted in the poplar forest. Snails, slugs and other reptiles can be found in the poplar forest. In the area near the base of the trunk, there are traces of Dendrobium candidum being eaten by snails, slugs and other reptiles. Treatment is carried out in accordance with the combinations and methods of the present invention. Specifically: prepare the composition of Baiji polysaccharide gum and fenugreek gum, apply the aqueous solution of the combined polysaccharide gum to the 50 cm area of ​​the base of the Metasequoia tree, and reapply every three months to ensure the viscosity of the combined polysaccharide gum. Compared with the control poplars in the same poplar grove, the roots of the poplars smeared with polysaccharide glue had sticky slugs, and the Dendrobium candidum planted on the poplars had no traces of being eaten away, while the Dendrobium candidum planted on the poplar trees had been eaten away. trace.

Embodiment 3

[0034] In Lishui, Jiangsu Province, Dendrobium candidum was planted on pear trees. Traces of snails, slugs and other reptiles can be found under the pear trees. In the area close to the base of the trunk, there are traces of Dendrobium candidum being eaten by snails, slugs and other reptiles. Treatment is carried out in accordance with the combinations and methods of the present invention. Specifically: prepare the composition of Baiji polysaccharide gum and Acacia japonica bean gum, apply the aqueous solution of the combined polysaccharide gum to the 50 cm area at the base of the pear tree, and reapply every three months to ensure the viscosity of the combined polysaccharide gum. Compared with the control pear trees in the same pear grove, the roots of the pear trees smeared with polysaccharide glue had sticky snails and slugs, and the Dendrobium candidum planted on the pear trees had no traces of being eaten away, while the Dendrobium candidum planted on the pear trees had no...

Abstract

The invention discloses a method for preventing and treating insect pests of dendrobium officinale imitated wild trees by utilizing plant polysaccharide gum and belongs to the technical field of plant biotechnology. The method is mainly applied to the biological insect prevention for the rare medicinal dendrobium officinale. The plant polysaccharide gum is a natural macromolecule formed by monosaccharide and uronic acid, has excellent viscosity and can be combined with water for forming a colloidal solution. One plant polysaccharide gum or the combined adhesive of two and more of plant polysaccharide gum of rhizoma bletillae, fenugreek, Chinese honey locust, gleditsia heterophylla and Tala is utilized to coat the base parts of the planted dendrobium officinale trees; the viscosity is utilized to prevent and treat creepers, such as snails and slugs; the plant polysaccharide gum is used as a drug carrier for preventing and treating the insect pests, such as scale insects, black cutworms and prodenia litura; the plant polysaccharide gum not only is suitable for planting trees but also can be applied to the bed legs and brackets of a facility cultivation bed. The method provided by the invention belongs to a biological control method, is simple and feasible, is high in preventing efficiency and is capable of effectively preventing and treating the dendrobium officinale insect pests.

Description

technical field [0001] The invention belongs to the field of plant biotechnology, and specifically relates to a method for preventing and controlling insect pests in Dendrobium officinale imitating wild trees by using plant polysaccharide gums such as basil, fenugreek, acacia, acacia, and Tara. Reptiles such as snails and slugs, and pests such as scale insects, cutworms, and Spodoptera litura. Background technique [0002] Dendrobium officinale Kimura et Migo is a perennial epiphytic herb of the genus Dendrobium in the family Orchidaceae, and is a unique and precious medicinal material in my country. Dendrobium officinale has the effects of nourishing the stomach and promoting body fluid, nourishing yin and clearing heat, anti-cancer and anti-aging, etc. The effect is remarkable, but the price is expensive. Dendrobium candidum likes a damp environment, its natural reproduction rate is extremely low, and wild resources are increasingly scarce due to massive and destructive m...
