Embodiment 1
[0077] A method for regulating the diversity of soil nematodes with modified nanocarbons:
[0078] (1) Handling of materials:
[0079] The collected soil samples were passed through a 2 mm sieve and mixed for use; soil properties were: pH 7.44, organic matter content 4.68, total nitrogen 0.21%, total phosphorus 22.03 mg·kg -1 , the saturated water content is 0.58 mL g -1 , and the soil sample was passed through a 2 mm sieve and mixed for use;
[0080] Tall fescue (tall fescue) Festuca arundinacea L . );
[0081] The particle size of nanocarbon is 20 nm, and the specific surface area is 1.2×10 5 m 2 ·kg -1 , pH 7, modified before application to obtain KMnO 4 , H 2 SO 4 or HNO 3 Modified nanocarbon;
[0082] (2) Experimental method:
[0083] 1) The experiment used plastic flower pots with a height of 25 cm and a diameter of 12 cm. The gauze was washed and dried, and then cut into a circular fixed flower pot with a suitable size. Each container weighed 2 kg of ma...

Embodiment 3
[0098] A method for regulating the diversity of soil nematodes with modified nanocarbons:
[0099] (1) Handling of materials:
[0100] The collected soil samples were passed through a 2 mm sieve and mixed for use; soil properties were: pH 7.44, organic matter content 4.68, total nitrogen 0.21%, total phosphorus 22.03 mg·kg -1 , the saturated water content is 0.58 mL g -1 , and the soil sample was passed through a 2 mm sieve and mixed for use;
[0101] Tall fescue (tall fescue) Festuca arundinacea L . );
[0102] The particle size of nanocarbon is 50nm, and the specific surface area is 1.2×10 5 m 2 ·kg -1 , pH 7, modified before application to obtain KMnO 4 , H 2 SO 4 or HNO 3 Modified nanocarbon;
[0103] (2) Experimental method:
[0104] 1) The experiment used plastic flower pots with a height of 25 cm and a diameter of 12 cm. The gauze was washed and dried, and then cut into a circular fixed flower pot with a suitable size. Each container weighed 2 kg of mat...
