Embodiment 1

[0030] Embodiment 1 is used for the preparation of Panax notoginseng anti-heavy cropping soil conditioner

[0031] Each microbial strain that has been fermented (the fermentation method here is according to the fermentation method disclosed in the prior art) is compounded to form a mixed bacterial liquid, and the number of active bacteria of each microbial bacterium in the mixed bacterial liquid is as shown in Table 1 (Table 1 Among them, cfu / mL refers to the total number of bacteria contained in each milliliter sample; cfu / g refers to the total number of bacteria contained in each gram of sample), and then mix the mixed bacterial solution with the carrier (the use of mixed bacterial solution and carrier The amount is shown in Table 1), at 15 ℃, fermented under the condition of moisture content 25%, leave after 72 hours and get final product. Table 2 is the specific material source of the strains used in the examples of the present invention.

Embodiment 2

[0032] Embodiment 2 is used for the preparation of Panax notoginseng anti-heavy cropping soil conditioner

[0033] The ratio of raw materials is shown in Table 1, the fermentation temperature is 30° C., the water content is 30%, and it is placed for 48 hours. Other methods are the same as in Example 1.

Embodiment 3

[0034] Embodiment 3 is used for the preparation of Panax notoginseng anti-heavy cropping soil conditioner

[0035] The ratio of raw materials is shown in Table 1, the fermentation temperature is 45° C., the water content is 40%, and it is placed for 120 hours. Other methods are the same as in Example 1.

Abstract

The invention belongs to the technical field of agricultural microorganisms and particularly relates to a soil conditioner for resisting pseudo-ginseng continuous cropping diseases and improving the survival rate of pseudo-ginseng seedlings. The soil conditioner for resisting the pseudo-ginseng continuous cropping diseases comprises active components including bacillus subtilis, bacillus licheniformis and trichoderma fungi; and the bacterial count ratio bacillus subtilis to bacillus licheniformis to trichoderma fungi in the soil conditioner is (0.5-2) to (0.2-1.8) to (0.3-1.5). The soil conditioner is used for pseudo-ginseng continuous cropping fields and can be used for increasing the content of beneficial microorganisms in soil, reducing the production of harmful pathogenic bacteria, promoting decomposition of organic matter, effectively reducing yellow seedlings, weak seedlings and dead seedlings caused by continuous cropping, and improving the survival rate of the pseudo-ginseng seedlings.

Description

technical field [0001] The invention belongs to the technical field of agricultural microbes, and in particular relates to a soil conditioner resistant to repeated cropping diseases of Panax notoginseng and its preparation and application. Background technique [0002] The authentic production area of ​​Panax notoginseng is around Wenshan, Yunnan, and its unique environmental requirements make its production account for 90% of the national production. Due to the extensive use of chemical fertilizers and pesticides, the soil ecosystem formed by soil-microbes-notoginseng roots has been severely damaged, beneficial bacteria have been inhibited, and pathogenic fungi, such as rot-inducing bacteria and Phytophthora, have spread and grown, resulting in three 7. Frequent cropping diseases, such as root rot, withering, yellow seedlings, mosaic leaves, black spots, etc., make the newly reclaimed forest soil cannot be reused after planting 3-5 years (one crop) of Panax notoginseng. It...
