Problems solved by technology

At present, the main method of control is still chemical control, which is very harmful and seriously damages the ecological environment. Especially in the protection of ancient trees, it is difficult to use general methods to achieve good results, and it may cause a certain degree of harm to ancient trees.

specific Embodiment approach

[0021] Selectivity experiments were used to count the selectivity of termites to the soil treated with and without biochar after a certain period of time. The specific implementation is as follows:

[0022] Collect the soil back from the vicinity of the original termite nest group in the field, dry and pulverize, pass through a 20-mesh sieve, and configure the application amount of 5%, 10% and 20% biochar for soil treatment respectively by weight ratio (dry sample). Add biochar to the soil so that the weight ratio of biochar is: 5%, 10% and 20%), the soil without biochar is used as the control group (denoted as CK), and every 500g contains biochar Add 80ml of water to the soil or CK soil without biochar application, mix well, and set aside. Experimental device such as figure 1 , three small basins (5.5cm in diameter, 5.5cm in height, 0.5cm away from the bottom, and a circular hole with a diameter of 1.0cm in the side) are placed at right angles, and each small basin is compo...

Embodiment 2

[0031] Using a non-selective experiment, termites are placed in the soil applied with biochar, and after a certain period of time, whether they leave is analyzed to judge their avoidance effect. The specific implementation method is as follows:

[0032] Collect the soil back from the vicinity of the original termite nest group in the field, dry it and pulverize it, pass through a 20-mesh sieve, pass through the weight ratio (dry sample), configure the application amount of biochar of mass fraction 5%, 10% and 20% respectively for soil treatment, The soil without biochar was used as the control group (denoted as CK). For every 500g of biochar-containing soil or soil, add 80ml of water, mix well, and set aside. Experimental device such as image 3 , consisting of two small basins (diameter 5.5cm, height 5.5cm, a circular hole 0.5cm from the bottom) connected by a hollow pipe (inner diameter 0.7cm, outer diameter 1.0cm, length 5.5cm) , The pipe is convenient for termites to cho...

Abstract

The invention discloses an application of biomass charcoal in preparation of a termite repellent. It is found in the invention that biomass charcoal can effectively repel termites when applied to soil. Therefore, termites can be repelled by applying a certain amount of biomass charcoal to the soil. The termite repellent has a good repellent effect, is green and harmless, and can promote crop growth and the like. When used for dam protection and ancient wood protection, the termite repellent not only can achieve the purpose of repelling termites, but also can improve the soil environment, is beneficial to growth of forest vegetation, and is superior to other chemical repellents in the aspect of interaction with the environment.

Description

technical field [0001] The invention belongs to the field of termite control, and in particular relates to the application of biomass charcoal in the preparation of termite repellents. Background technique [0002] Termites are a worldwide important pest, especially in tropical and subtropical regions. my country has been found to be distributed in 23 provinces and cities, and the endangered area is close to 40% of the total area of ​​the country (Huang Fusheng et al., 2000). They are highly proliferative and quick to destroy, causing huge damage in a short period of time. The economic loss caused by termite damage is about 2 billion to 2.5 billion yuan per year (Li Xiaoying and Wang Yiyan, 2003). At present, the main method of control is still chemical control, which is very harmful and seriously damages the ecological environment. Especially in the protection of ancient trees, it is difficult to use general methods to achieve good results, and it may cause a certain degr...
