When determining the distribution ratio or content of each group, the action characteristics and toxicity of the three agents should be measured, and the main purpose of the formulation should also be considered. In this study, on the basis of pre-tests in the early stage, set single use and mixed dosage. Water containing no medicine, containing the same solvent and emulsifier was used as a blank control.

2.2.2) Repeat the test

Each treatment was repeated 4 times, each time with 3 pots, 30 weed seeds were planted in each pot, and a total of 90 grains were treated per treatment.

2.3), processing method

2.3.2), Use of equipment and medication

The cultivated test materials are evenly placed on a platform with an area of 0.5m ² and sprayed with the surface layer of the 3WP-2000 walking spray tower. The spray volume is 450 kg/ha. Spray pressure 0.3MPa. After all the liquid medicine is sprayed, the gas valve is closed. After 30 seconds, the spray tower door is opened and the nutrition bowl is taken out. Then open the air valve and spray 50mL of clean water to clean the spray tube.

3) Test method

4) Data survey and statistical analysis

4.1), survey method

4.2), investigation time and frequency

Survey 15 days after the treatment, a total of 1 survey.

4.3), data statistical analysis

The Colby test was used to evaluate the type of joint action of any two or a mixture of the three on weeds.

At 15d, cut the green tissue on the ground of each treatment, weigh it with an electronic balance, and calculate the actual survival rate: E (%) = (fresh weed weight in treatment area/fresh weed weight in control area) × 100

The theoretical weed survival rate calculation formula is: E0 (%) = X × Y/100 (binary mixed use)

Where X represents the weed survival rate of A when the dosage is P, Y represents the weed survival rate of B when the dosage is Q, E0 represents the theoretical weed survival rate of A+B when the dosage is (P+Q), and E represents Actual weed survival rate for each treatment.

E0(%)=X×Y×Z×…×N/100 ^(n-1) (Mixed with ternary and above)

In the formula, X, Y, Z, N respectively represent the actual survival rate of n single agents, n is the number of compound herbicide varieties.

When E0-E>10%, it indicates synergistic effect; when E0-E<-10%, it indicates antagonistic effect; when E0-E is within ±10%, it indicates additive effect.
