Embodiment 1

[0013] A method for planting Sophora japonica in a flue-cured tobacco field to lure pests such as aphids with trapping belts. The current cultivation method of flue-cured tobacco is maintained. The distance between the plants is 1 meter, that is, a row of Acacia japonica is planted at both ends of the flue-cured tobacco plot, and a row of Acacia japonica is planted on both sides of the plot parallel to the tobacco ridge, and the flue-cured tobacco plot is surrounded in the middle. complete.

Embodiment 2

[0015] A method for planting Sophora japonica in a flue-cured tobacco field to lure pests such as aphids with trapping belts. The current cultivation method of flue-cured tobacco is maintained. The distance between the plants is 0.8 meters, that is, a row of Saccharia japonica is planted at both ends of the flue-cured tobacco plot, and a row of Saccharia sativa is planted on both sides of the plot parallel to the tobacco ridge, and the flue-cured tobacco plot is surrounded in the middle. complete.

Embodiment 3

[0017] A method for planting Sophora japonica in a flue-cured tobacco field to lure pests such as aphids with trapping belts. The current cultivation method of flue-cured tobacco is maintained. The distance between the plants is 1.3 meters, that is, a row of Acacia japonica is planted at both ends of the flue-cured tobacco plot, and a row of Saccharia japonica is planted on both sides of the plot parallel to the tobacco ridge, and the flue-cured tobacco plot is surrounded in the middle. complete.

[0018] Control group:

[0019] On the basis of the examples, only flue-cured tobacco was planted, and no pagoda japonica was planted, and other planting methods and conditions were consistent as a control field.

Abstract

The invention discloses a pest control method for a tobacco field. Sophora japonica is planted around the tobacco field to form a trapping zone, on the basis of 5 mu of the tobacco field, the spacingof the Sophora japonica is 0.8-1.2 m, row spacing of flue-cured tobacco is 120 cm, plant spacing is 50 cm, and the Sophora japonica is planted before transplanting of the flue-cured tobacco. With adoption of the technical scheme, the Sophora japonica trapping zone capable of effectively trapping aphids and other pests in the flue-cured tobacco field is established, harm of the pests is controlledby the aphid trapping plant Sophora japonica, the application frequency and the residual quantity of pesticides in the tobacco field are reduced, and quality and safety of tobacco leaves are improved.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a method for controlling pests in tobacco fields. Background technique [0002] The use of chemical pesticides to control aphids in tobacco agriculture is still one of the most important control means and measures. For a long time, people have been accustomed to using pirimicarb and omethoate to prevent and control aphids, resulting in increasing resistance of aphids and killing a large number of natural enemies. Due to the extensive use of chemical pesticides, ecological damage and environmental pollution have become the main obstacles to agricultural production. Using ecological principles to restore ecological balance and virtuous circle and promote the development of agricultural production is an important task at present. Significantly reducing the use of chemical pesticides has important ecological significance. [0003] Trapping plants are plants used to lure pes...
