Problems solved by technology

[0003] Because most of the spore preparations of Trichoderma are living bacteria preparations, they are easily affected by complex factors in the soil. At the same time, the soil provides limited nutrients, which often cannot provide enough nutrients for Trichoderma to germinate and reproduce in large numbers, and in the current mechanized production Under the general environment, some original dosage forms are difficult to meet the requirements of mechanized fertilization

Embodiment 1

[0022] Trichoderma sorghum granules are prepared by the method of the present invention. Corn seeds (Zhengdan 958) that have been germinated in dark conditions for 2-3 days at 28°C are put into flower pots together with the granules. Each pot contains 10 corn seeds and inoculates 1 g of them respectively. , 2g, and 3g granules were treated three times, and each treatment was repeated 5 times. With no granules as a control, the emergence rate and plant height of corn were detected when the corn grew to the three-leaf stage.

[0023] The results showed that the three treatments of 1g, 2g and 3g of granules all promoted the plant height and emergence rate, which were higher than CK. When the treatment dosage was 1g and 2g, the emergence rate was the same and the promoting effect was obvious, but the plant height of 1g treatment dosage was lower than that of 2g treatment dosage. It is concluded that Trichoderma sorghum granules have a growth-promoting effect on corn growth, and th...

Embodiment 2

[0025] Trichoderma sorghum granules prepared by the method of the present invention are compounded with chemical pesticide Manshijin granules in the following ratios: 1:1 (g / g), 5:1 (g / g), 10:1 (g / g) ) were tested as three treatments. Take corn seeds (Zheng Dan 958) that have been germinated in the dark at 28°C for 2-3 days, and put them into flowerpots together with the compound granules, with 10 corn seeds per pot, and 5 replicates for each treatment, without granules As a control, the emergence rate and plant height of corn were detected when the corn grew to the three-leaf stage.

[0026] The results showed that the compound ratios of 1:1 (g / g) and 5:1 (g / g) both promoted plant height and emergence rate, which were higher than CK. When the compound ratio is 10:1 (g / g), it can promote the plant height but have a certain inhibitory effect on emergence. It can be seen from the results that the compound ratio of 1:1 (g / g) has achieved the best promotion effect on plant heigh...

Abstract

The invention relates to a preparation method of trichoderma biocontrol granules. According to the preparation method, sorghum seeds are soaked by fermentation bacterium liquid prepared by antifungal trichoderma strains and trichodermaharzianum SH2303, then, the soaked sorghum seeds are taken out, film-forming agents and nutrition bodies are covered, and prepared granules are stored after being dried. The goals of preventing and controlling soil-borne diseases and promoting the crop growth can be realized through the antifungal trichoderma strains. The preparation method overcomes the defects that the nutrition in soil is insufficient, the environment is complicated, trichoderma is influenced, and the mechanical fertilization cannot be implemented. The nutrition for the massive propagation of the antifungal trichoderma is provided, and the competitiveness of the trichoderma in the soil is improved. The preparation method can also be used for preparing other biocontrol agent granules, in addition, the compounding among different biocontrol agents can be realized, and the goal of synergistically preventing and controlling pest and disease damage is reached.

Description

technical field [0001] The invention relates to a preparation method of a Trichoderma biocontrol preparation, in particular to a preparation method of adsorbing an antagonistic Trichoderma on a carrier and wrapping it with other nutrients to provide nutrition. Background technique [0002] At present, the Trichoderma fungi commonly used in production are mostly spore preparations. The spore preparation made by fermenting Trichoderma is used for seed coating or soil treatment. There are as many as 11 kinds of Trichoderma preparations registered at home and abroad. These include 5 preparations of Trichoderma harzianum, such as Topshield (T.harzinum T-22 strain) from the United States. Israel's Trichodex (T.harzinum T-39 strain), etc. Lewis et al. (1983) studied the amount of spores produced by Trichoderma on various solid media. Corn flour and peanut shell powder have the same effect as wheat bran in stimulating Trichoderma sporulation. Zhao Peijie et al. have done researc...
