AI Technical Summary

Problems solved by technology

Chemical pesticides are less effective as slugs hide under pine needles
In addition, the cost of pine needles is high, and the cost of chemical control is also high, which is not conducive to large-scale control of the damage of slugs to Panax notoginseng plants

Embodiment 1

[0018] 1. Preparation of raw materials

[0019] a. Collect iron wire grass and shake off the soil on it to prevent it from carrying pathogenic bacteria;

[0020] b. Use a guillotine to cut the wire grass into 3-5cm grass sections, spread them out and dry them in the sun

[0021] c. When the water content is 8-15%, it can be used.

[0022] 2. Cover

[0023] Sowing is carried out according to the conventional Panax notoginseng sowing method. After covering with soil, the prepared iron wire grass section is evenly spread on the Panax notoginseng seedbed, and its thickness is between 0.5-1cm.

[0024] 3. Watering

[0025] The watering is carried out by sprinkler irrigation. The first watering should be fully watered, and then the water should be replenished in real time to keep the soil moisture content at about 20%-25%.

[0026] 4. Panax notoginseng fertilization

[0027] When the emergence rate of Panax notoginseng reaches 70%-90%, and the chlorophyll content is at 15-20SPA...

Abstract

The invention provides a method for effectively controlling the harm of slugs to Panax notoginseng seedlings. In the present invention, the mulch pine needles commonly used in the cultivation of Panax notoginseng seedlings are replaced by air-dried iron wire grass, and the thickness of the air-dried iron wire grass is 0.5-1.0 cm, the dried ironwort will slowly bond with the soil under water erosion, forming an approximate vacuum, which changes the original loose environment covered by pine needles, making it impossible for slugs to hide. Expose to death. The present invention is based on ecological principles and guided by the principle of controlling pests and diseases by agricultural biodiversity, and changes the living environment of pests so that they cannot survive, so as to achieve the purpose of continuously controlling pests.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a method for effectively controlling damage caused by slugs of Panax notoginseng seedlings. Background technique [0002] The main pests in the production and cultivation of Panax notoginseng are aphids, scale insects, thrips, and slugs. Among them, slugs are the most harmful, longest-lasting, and most difficult pests to control. Slugs mainly harm Panax notoginseng plants with adults. During the emergence stage of seedlings and second-year-old and third-year-old slugs, they harm young shoots before emergence and cause seedling deficiency. , the leaves are eaten into holes and notches, and in severe cases, the young stems are eaten up, resulting in missing plants and broken ridges; during the blooming period of biennial and three-year-old Panax notoginseng, slugs climb from the stem to the upper part of the plant and harm the moss, pedicels, and florets , resulting in r...
