Uniformly placing the cultured test material on a 0.5m area2Spraying stem and leaf by using a 3WP-2000 model walking spray tower on the platform, wherein the liquid spraying amount is 450 kg/hectare. The spraying pressure is 0.3 MPa. And after all the liquid medicine is sprayed, closing the air valve, opening the spraying tower door after 30 seconds, and taking out the nutrition pot. Then the air valve is opened, 50mL of clean water is sprayed, and the liquid spraying pipe is cleaned.
3) Test method
The potting method is adopted. The weed cultivation is shown in 1.1), and the method is carried out according to 'herbicide in pesticide indoor bioassay test guidelines'. The application method is shown in 2.3.2), and stem and leaf treatment method is adopted. After treatment, the cells were transferred to a greenhouse for conventional culture.
4) Data investigation and statistical analysis
4.1) investigation method
The complete survival weed seedlings are cut off along the soil surface by a blade by adopting an absolute number survey method, and the fresh weight of the weeds is weighed by an analytical balance. For the weeds that have died, the fresh weight is zero.
4.2), investigation time and number of surveys
The investigation was carried out 20 days after the treatment, and the total number of the investigations was 1.
4.3), statistical analysis of data
The theoretical fresh weight inhibition rate (E0 ═ X + Y-X Y/100) of each treatment mixed combination is calculated by a Gowing method, and then compared with the actually measured inhibition rate (E), the combined action type of the two mixed combinations on the weeds is evaluated, and when the E-E0 value is more than 10 percent, the effect is synergistic, when the E-E0 value is less than-10 percent, the effect is antagonistic, and when the E-E0 value is between-10 percent and 10 percent, the effect is additive. And the optimal proportion is determined according to factors such as actual control effect, characteristics of the herbicide, balance of the formula and the like. Wherein X is the fresh weight inhibition rate when the dosage of the active component A is P; y is the fresh weight inhibition rate of the active component B when the dosage is Q.
