Embodiment 1

[0038] Embodiment 1: clear water spraying. At 7 o'clock in the evening, 100 strong potted seedlings of Dendrobium officinale 2 years old were sprayed with clear water, and the snail damage situation was observed and recorded on the 1st day, 3rd day, and 5th day after spraying, and the number of damaged plants was recorded respectively.

Embodiment 2

[0039] Embodiment 2: Spraying of garlic extract. Add garlic and salt to make mashed garlic, the mass ratio of garlic to salt is 1:0.1, soak in water for 4 hours, the mass ratio of garlic to water is 1:8, stir once every 1 hour during this period, and then filter and separate with 100-mesh gauze Obtain the extraction stock solution. The extraction stock solution was diluted 300 times with clear water and then sprayed. The spraying method and data records were the same as in Example 1.

Embodiment 3

[0040] Embodiment 3: Spraying of tea dry powder extract. Soak the tea dry powder in warm water for 8 hours, the mass ratio of tea dry powder to warm water is 1:12, the temperature of the warm water is 50°C, stir once every hour during this period, and then filter and separate with 200-mesh gauze to obtain the extraction stock solution. The extraction stock solution was diluted 300 times with clear water and then sprayed. The spraying method and data records were the same as in Example 1.

Abstract

The invention discloses a method for preventing damage by snails in organic cultivation of Dendrobium officinale Kimura et Migo by using tea cake powder extract, which includes the following steps: preparing tea cake powder extract solution; preparing garlic extract solution; mixing the tea cake powder extract solution with the garlic extract solution to obtain mixed extract solution; diluting themixed extract solution with water by a factor of 100 to 300; and evenly spraying the mixed extract solution diluted by a factor of 100-300 on Dendrobium officinale Kimura et Migo cultivation seedlingbeds at 7-9pm every 5-7 days during the periods from March to May and from September to November. The garlic extract prevents damage by snails mainly by odor. By mixing the two kinds of solutions atan appropriate ratio and setting the application time, snails can be repelled. Therefore, the yield of Dendrobium officinale Kimura et Migo is improved, and the eating safety is ensured.

Description

technical field [0001] The invention relates to the organic cultivation of dendrobium candidum, in particular to a method for preventing and controlling snail damage in the organic cultivation of dendrobium candidum by using tea dry powder extraction liquid. Background technique [0002] Dendrobium officinale Kimura et Migo (Dendrobium officinale Kimura et Migo) is a perennial epiphytic herb belonging to the genus Dendrobium officinale and is one of the most precious Chinese herbal medicines in my country.
