Embodiment 1

[0026] The preparation of embodiment 1 Momordica grosvenori biomimetic extract

[0027] Follow the steps below:

[0028] (1) drying and pulverizing the roots of Luo Han Guo, and passing through a 100-mesh sieve to obtain the root powder of Luo Han Guo;

[0029] (2) Preparation of bionic extract: 0.2% sodium chloride, 0.32% pepsin and 0.02mol / L hydrochloric acid, adjust pH=5.5;

[0030] (3) Mix according to the weight ratio of Luo Han Guo root and biomimetic extract 1:30, heat in a water bath at 37°C, seal with a plastic film, extract with magnets for 120 minutes, filter, collect the filtrate, concentrate in a water bath to 1 / 4 volume, and collect the concentrate;

[0031] (4) Mix the concentrated solution in step (3) with ethyl acetate-butyl acetate solution in a volume ratio of 1:4, extract 3 times, collect the organic phase, remove the solvent by rotary evaporation under reduced pressure, and obtain a white powder, which is Monk Fruit Root Biomimetic Extract.

Embodiment 2

[0032] Example 2 Chinese medicine granules containing the biomimetic extract of Luo Han Guo root

[0033] Composition of raw materials: 15 parts of biomimetic extract of Luo Han Guo root, 15 parts of deer vine root, 10 parts of Tripterygium wilfordii, 4 parts of quicklime;

[0034] Preparation steps:

[0035] (1) Grind Deutschia Root and Tripterygium wilfordii, add water with a weight ratio of 1:10, soak for 1 hour, decoct for 2 hours, filter, then add filter residue with water with a weight ratio of 1:8, decoct for 2 hours, and concentrate to a density of 0.9 -1.5, add maltodextrin, spray dry to obtain spray powder;

[0036] (2) Adding the biomimetic extract of Luo Han Guo root, quicklime and 90% ethanol solution to the spray powder prepared in step (1), making granules, drying, sizing, and packaging to make blood lipid-lowering granules.

Embodiment 3

[0037] Embodiment 3 Chinese medicinal liquid containing the biomimetic extract of Luo Han Guo root

[0038] Composition of raw materials: 13 parts of biomimetic extract of Luo Han Guo root, 12 parts of deer vine root, 7 parts of Tripterygium wilfordii, 2 parts of quicklime.

[0039] Preparation steps: pulverize the roots of Dergonia wilfordii and Tripterygium wilfordii, add water with a weight ratio of 1:10, soak for 1 hour, decoct for 2 hours, filter, then add filter residue with water with a weight ratio of 1:8, decoct for 2 hours, and concentrate to a density of 0.6 -0.8, add the biomimetic extract of Luo Han Guo root dissolved in water and quicklime, mix evenly, continue to concentrate until the density is 0.7-0.9, and make a traditional Chinese medicine liquid;

Abstract

The invention provides an application of traditional Chinese medicine composition containing a momordica grosvenori root bionic extract in resisting root-knot nematodes. The traditional Chinese medicine composition containing the momordica grosvenori root bionic extract is prepared from raw materials in parts by weight as follows: the momordica grosvenori root bionic extract, derris roots, commonthreewingnut roots and quicklime. A method for controlling root-knot nematodes of momordica grosvenori is characterized in that a medicine liquid is prepared from traditional Chinese medicine granulesor medicine liquids containing the momordica grosvenori root bionic extract and water in the weight ratio being 1:10, the medicine liquid is sprayed or irrigated into momordica grosvenori fields at the dosage of effective components of 80 g / mu, and the medicine liquid is applied once every day and continuously applied for 7 days. The traditional Chinese medicine composition has a remarkable effect of resisting the root-knot nematodes, and the safe, effective and environment-friendly method is provided for control of the root-knot nematodes.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a traditional Chinese medicine composition for resisting root-knot nematodes and an application thereof. Background technique [0002] Nematodes belong to the phylum Nematodes and are a class of lower animals with a wide variety. Nematodes live in soil, sea water and fresh water, and also parasitize humans, animals and plants, causing diseases. Plant parasitic nematodes or plant parasitic nematodes that parasitize on plants and cause diseases are called plant pathogenic nematodes. Root-knot nematode is a highly specialized omnivorous plant pathogenic nematode. Root-knot nematodes have a wide host range of more than 2000 plant species, including monocots, dicots, herbaceous plants and woody plants. They account for more than 90% of the losses of crops and belong to the worldwide distribution. The commonly used nematode control methods include crop rotation for disease pr...
