Embodiment 1

[0014] (1) By weight, 45 parts of Spartina alterniflora, 20 parts of phoenix leaves, 10 parts of Calculus Calculus, 7 parts of Radix Paeoniae Alba, and 20 parts of Dandelion. Mix and pulverize, and sieve with a 20-mesh sieve, and discard coarse raw materials to form raw materials;

[0015] (2) Add 12 parts of distilled water to the above raw materials and heat them to 85°C, then add 0.0005 parts of mannanase for the first enzymolysis. During this process, the temperature is maintained at 80-85°C for 3 hours to obtain the first secondary enzymatic solution;

[0016] (3) Add sodium hydroxide to the first enzymolysis solution to adjust the pH value to 8.0-8.5, lower the temperature to 50°C, add 0.0015 parts of xylanase for the second enzymolysis, and maintain the temperature at 80°C during the process -85°C to obtain the second enzymatic hydrolysis solution.

Embodiment 2

[0018] The method is the same as in Example 1, except that 40 parts of Spartina alterniflora, 25 parts of phoenix leaves, 13 parts of Calculus Calculus, 11 parts of Radix Paeoniae Alba, and 22 parts of Dandelion are mixed and pulverized by weight.

Embodiment 3

[0020] The method is the same as in Example 1, except that 43 parts of Spartina alterniflora, 24 parts of phoenix leaves, 14 parts of Calculus Calculus, 9 parts of Radix Paeoniae Alba, and 21 parts of Dandelion are mixed and pulverized by weight.

Abstract

The invention discloses a natural repellent for forestry pine moth. The preparation process of the natural repellent comprises the following steps: mixing marigold, phoenix tree leaves, radix salviae miltiorrhizae, calculus bovis, agastache rugosus, radix paeoniae alba, herba taraxaci, Japanese ardisia herb and venenum bufonis; performing micro-grinding; sieving with a 20-mesh screen, and discarding thick and big raw materials to form a raw material; adding 10-16 parts of distilled water into the raw material, heating up to 80-85 DEG C, and conducting twice enzymolysis. As marigold, phoenix tree leaves, radix salviae miltiorrhizae, calculus bovis, agastache rugosus, radix paeoniae alba, herba taraxaci, Japanese ardisia herb and venenum bufonis are mixed proportionally and subjected to twice enzymolysis, the enzymatic hydrolysates have a favorable repelling effect on pine moth, pine moth has sensitive resisting behavior to the natural repellent, and experiments show that the pine moth repelling rate can be about 85% and no toxic or side effect is caused.

Description

technical field [0001] The invention relates to a natural repellent for forestry pine caterpillars. Background technique [0002] Masson pine is planted in a wide range in the south, and a large number of masson pine are planted on Zimao Mountain, which is the most common place for people to climb. Masson pine caterpillar is a major pest that endangers the growth of masson pine. The masson pine caterpillar belongs to Lepidoptera, Sagittaridae, also known as trichotomy, caterpillar, mainly damages masson pine, and also damages black pine, slash pine, and loblolly pine. It is a historical forest pest in my country. It feeds on pine needles with larvae. When a large-scale outbreak occurs, the contiguous pine forest can be eaten away within a few days. From a distance, it looks yellow and scorched, like a fire. It is often called "forest fire without smoke". , and the severe ones cause the pine trees to die. After being harmed by the masson pine caterpillar, it is easy to att...
