Embodiment 1

[0030] The preparation of embodiment 1 metarhizium anisopliae granule

[0031] Take rice and vermiculite with a mass ratio of 5:10, and after autoclaving for 100 minutes, insert Metarhizium anisopliae. The inoculum amount of the liquid strain is 10% (mL / g). The water content is up to 70%, the amount of culture medium is 1 / 2 of the culture tank, and solid-state fermentation is carried out in a sterile constant temperature and humidity culture room at 25°C for 14 days. During this period, there is an important link, that is, the mycelium to be grown covers the fermentation medium Finally, it is necessary to shake the culture tank to fully disperse the mycelium, which can increase the spore production by 50%. The fermented product and light calcium carbonate were compounded at a ratio of 10:2 to obtain Metarhizium anisopliae granules, sealed with a vacuum sealing machine, and stored at 15°C.

[0032] After testing, the quality parameters of the Metarhizium anisopliae granule are...

Embodiment 2

[0033] The application of embodiment 2 metarhizium anisopliae granules

[0034] From late April to early May, 37.5kg / hm of Metarhizium anisopliae was applied during the plowing period of the bamboo forest 2 (ie 2.5kg / mu). The pesticide application method adopts furrow application, the furrow width is 20cm, the distance between the furrows is 50-80cm, and the furrow depth is 20-30cm. After the bacterial agent and sand are evenly mixed at a mass ratio of 1:5, they are applied in the furrow and then covered with soil. When the time comes, it can be mixed and applied together with the fertilizer; it will be applied again from early October to late October of the same year.

Embodiment 3

[0035] Example 3 Applying Metarhizium anisopliae granule and using chlorpyrifos granule control effect contrast

[0036]The test forest is located in Shanming Village, Deqing County, Huzhou City, Zhejiang Province, and the bamboo species is Zaoyuanzhu. Set up two different test control areas for the application of Metarhizium anisopliae granules and chlorpyrifos granules, each with an area of ​​20m × 20m, with no treatment blank as the control, and each treatment repeated 3 times. Each test area is separated by 5m. The method of administration of Metarhizium anisopliae granules is as described in Example 2. Chlorpyrifos granules are applied when plowing, and the application rate is 2.5kg / mu. Metarhizium anisopliae granules are applied continuously for three years, and chlorpyrifos granules are applied continuously for four years.

[0037] Before the experiment, during the period from mid-March to mid-April, regularly (every 7 days) the data on the damage rate of bamboo shoot...

Abstract

The invention discloses a biological prevention and control method for wireworms in a bamboo forest, which comprises the following steps: in a wireworm damage period, applying Metarhizium anisopliae granules in a bamboo shoot forest land to prevent and control the wireworms; the metarhizium pingshaense granules are prepared by performing solid fermentation on metarhizium pingshaense WP08 strains and then compounding the fermented metarhizium pingshaense WP08 strains with light calcium carbonate, the spore content of the metarhizium pingshaense WP08 strains is 30-60 billion spores / g, the viable spore rate is greater than or equal to 90%, the infectious microbe rate is less than or equal to 5%, and the storage stability is greater than or equal to 80%. According to the activity law of wireworms in the bamboo forest, the green muscardine fungus granules are used for specifically preventing and treating the wireworms in the bamboo forest, the prevention and treatment targeting is clear, the specificity is high, the prevention and treatment effect is good, the safety of bamboo shoot food and the planting environment is guaranteed, 100% replacement of chemical pesticides can be achieved, and the yield and quality of the bamboo shoots are improved.

Description

technical field [0001] The invention belongs to the technical field of biological control, and in particular relates to a biological control method for the bamboo forest needleworm. Background technique [0002] Bamboo is an important forest resource in China, and occupies a pivotal position in the development of forestry economy in my country with its unique growth adaptability and economic value. Bamboo shoots are the most critical link in the growth and development of bamboo, and are the basis for the renewal and continuation of bamboo forests. Simultaneously, bamboo shoots (and products thereof) are excellent dietary fibers and forest vegetables. [0003] Bamboo forest needleworm is the most harmful pest in bamboo shoot stage at present in bamboo shoot forest. Taking Zhejiang Province as an example, since 2010, the bamboo forest needleworm has sporadically occurred in a few bamboo production areas such as Lin'an and Deqing to the whole area, and the economic loss due t...
