Problems solved by technology

Soil-borne pathogens generally infect through soil and invade plant roots, stems, leaf orifices or wounds, causing crop root and even whole plant diseases, causing serious economic losses
At present, chemical control and screening of disease-resistant crop varieties are commonly used, which are only effective for a few soil-borne diseases, and have little effect on most soil-borne diseases, and the use of chemical pesticides will also cause pesticide residues and pollute the environment
At the same time, the long-term use of chemical pesticides will increase the resistance of pathogenic bacteria, resulting in a decline in the control effect or even failure.

Embodiment 1

[0016] The effect of Trichoderma inoculum plots on tomato yield, plot three treatments, treatment 1, 2, 3 repeated three times, a total of 9 treatment comparison experiments, each treatment plot 100kg farmyard manure, treatment 1 is 400 times of water, treatment 2 It is 600 times of water liquid, and treatment 3 is clear water control. Compared with the control, the yield of treatment 2 increased by 5.1%, and the yield of treatment 1 increased by 12% compared with the control, which was a significant increase.

[0017] The effect of Trichoderma inoculum on the yield per mu of tomato, the test set up three treatments 1, 2, 3, three repetitions of 1, 2, 3, a total of 9 treatment comparison experiments, each test applied 2000kg of farmyard manure, and treatment 3 was the control area , the yield of treatment 2 increased by 6.2% compared with the control, and the yield of treatment 1 increased by 12% compared with the control, which was a significant increase. Implemented by the ...

Embodiment 2

[0019] The influence of Trichoderma plots on cucumber yield, three treatments 1, 2, and 3 were repeated three times, a total of 9 treatment comparison experiments, each treatment plot 100kg farmyard manure treatment 3 was the control area, and the yield of treatment 2 increased by 51.6 compared with the control %, the yield of treatment 1 increased by 51% compared with the control, and the yield of treatment 2 increased by 51.6% compared with the control, which was a significant increase. Implemented by Shanghai Longfang Vegetable Gardening Farm, the test report was received on February 2, 2007.

Embodiment 3

[0021] The control effect of Trichoderma agent on watermelon Fusarium wilt was set as treatment 1, 2 and 3, and treatment 3 was the control area. The control effect of treatment 1 and 2 was 85.7% and 85.7% in 40 days after the first application; %, 85%; the 60-day control effect of the third medication was 73%, 80%; the 80-day control effect of the fourth medication was 68%, 56%, and the control effect was remarkable.

[0022] Effect of Trichoderma inoculum on sugar content of watermelon. Suppose processing 1, 2, 3, processing 1 is 400 times of water liquid, processing 2 is 600 times of water liquid, processing 3 is clear water contrast, and processing 1, 2 melon heart sugar content increases 11%, 11.4% respectively than contrast; Treatment 1 and 2 increased by 31% and 15% respectively compared with the control; it was implemented by Shanghai Longfang Vegetable Gardening Farm, and the test report was received on February 28, 2007.

Abstract

The invention relates to the technical field of biology and particularly relates to a temperature-sensitive trichoderma harzianum microbial agent carrier formula and a preparation process thereof. The temperature-sensitive trichoderma harzianum microbial agent carrier formula is characterized by being composed of the following raw materials in percentage by weight: 35%-45% of organic matter decomposed coal, 25%-35% of humic acid, 15%-25% of trichoderma harzianum fermented raw liquid and 5%-15% of diatomite. Compared with the prior art, a biological probiotic can be applied to various facilities including outdoor cultivation, greenhouse cultivation and the like, can be used for repairing soil and preventing soil-borne diseases, such as stem rot, wilt, damping-off, stalk break, rhizoctonia solani and root rots of various vegetables, grain crops, fruits, medicinal materials, flowers, nursery-grown plants and the like; microbes such as trichoderma harzianum and pathogenic bacteria interact; essentially, three organisms including trichoderma harzianum, plants and pathogenic bacteria interact.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a thermosensitive Trichoderma inoculum carrier formulation and a preparation process thereof. Background technique [0002] Use biological beneficial bacteria to develop and prevent soil-borne diseases, focusing on microbial soil-borne pathogens in soil-borne diseases. Soil-borne pathogens generally infect through soil and invade plant roots, stems, leaf orifices or wounds, causing crop root and even whole plant diseases, causing serious economic losses. At present, chemical control and screening of crop resistant varieties are commonly used, which are only effective for a few soil-borne diseases and have little effect on most soil-borne diseases. Moreover, the use of chemical pesticides will also cause pesticide residues and pollute the environment. At the same time, the long-term use of chemical pesticides will increase the resistance of pathogenic bacteria, resulting in a dec...
