Problems solved by technology

The use of chemical pesticides is not recommended because they are likely to cause pesticide residues and pollute the environment; soil fumigation and physical disinfection are two commonly used methods, but they also kill beneficial microorganisms in the soil

Embodiment 1

[0069] A method for safely adding microorganisms for the soil biocontrol of Panax notoginseng in continuous cropping. The method is that during the transplanting process of Panax notoginseng seed strips, the seed strips are treated with a microbial agent, and the hole application treatment is to sprinkle the microbial agent into the transplanted In the hole where the seed strips are planted, mix well with the soil in the hole and then transplant. Described microbial bacterial agent is bacillus, and application concentration is 10 5 cfu / mL, the size of the acupoints in the acupoint application treatment is 9cm×9cm; the dosage is 1g / acupoint.

[0070] The present invention applies the bacillus microbial bacterial agent to effectively control the diseases and insect pests of Panax notoginseng and the phenomena of continuous cropping obstacles by taking advantage of its advantages of rapid reproduction and strong vitality. Bacillus can occupy a space advantage and inhibit the gro...

Embodiment 2

[0072] A method for safely adding microorganisms for the soil biocontrol of Panax notoginseng. The seed strips are treated with a microbial agent, and the hole application treatment is to sprinkle the microbial agent into the hole where the seed strips are transplanted, and then fully mix it with the soil in the hole. transplant. Described microbial bacterial agent is Trichoderma, and application concentration is 10 6 cfu / mL, the size of the acupoints in the acupoint application treatment is 12cm×12cm; the dosage is 3g / acupoint.

[0073] The invention uses the Trichoderma microbial bacterial agent to inhibit the growth, reproduction and infection of pathogenic bacteria through the production of small molecule antibiotics and macromolecular antibacterial proteins or cell wall degrading enzymes by the Trichoderma. Trichoderma can seize water and nutrients, occupy space, consume oxygen, etc. through rapid growth and reproduction, so as to weaken and eliminate the gray mold patho...

Embodiment 3

[0075] A method for safely adding microorganisms for soil biocontrol in continuous cropping of Panax notoginseng, the method is that after the seed strips of Panax notoginseng are normally transplanted, after the seed strips emerge, the growth height of the seed strips emerging is 5-10 cm, and when the leaves are all unfolded, The root soil is irrigated with microbial agents. Described microbial bacterial agent is bacillus, and wherein the application concentration of bacillus is 10 2 cfu / mL.

[0076] In the present invention, the soil humidity is controlled at 25% to 30% during the irrigation treatment, which can not only promote the penetration of the bacterial solution into the deep layer of the soil, but also avoid the large loss of the bacterial agent caused by excessive humidity, thus affecting the protective effect of the microbial bacterial agent on Panax notoginseng .

[0077] In the process of irrigation treatment, the present invention dilutes the microbial inocul...

Abstract

The invention discloses a pseudo-ginseng continuous cropping soil biocontrol microbe safely adding method; the method uses microbe inocula to carry out hole application treatment before a pseudo-ginseng seed strip is transplanted, and / or to carry out fertigation treatment after the pseudo-ginseng seed strip is transplanted, wherein the microbe inocula refers to Bacillus spp and / or Trichoderma spp. The biocontrol microbe safely adding method can effectively control pseudo-ginseng diseases, and can effectively improve soil conditions especially on a pseudo-ginseng continuous cropping obstacle land, thus alleviating continuous cropping obstacles, improving pseudo-ginseng emergence rate and survival rate, and improving soil usage efficiency.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for safely adding microorganisms to soil biocontrol of Panax notoginseng continuous cropping. Background technique [0002] Panax notoginseng is a plant of the genus ginseng of Araliaceae, known as "gold does not change", "sacred grass of the south", "king of ginseng", etc. It is a rare and precious Chinese medicinal material unique to Yunnan and a bright pearl in Chinese traditional medicine. [0003] The soil of Panax notoginseng continuous cropping refers to the soil after one crop (2-3 years) of Panax notoginseng has been planted and excavated. If Panax notoginseng is planted again in the continuous cropping soil of Panax notoginseng, the emergence rate will decrease, and the root rot of Panax notoginseng will be serious in the later period, resulting in a large reduction in yield and no harvest of Panax notoginseng. This is the obstacle of continuous cropping ...
