4) Data investigation and statistical analysis
4.1) investigation method
The living weed seedlings were cut off by absolute number survey along the soil surface with a blade, and the fresh weight of the weeds was weighed with 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 15 days after the treatment, and was carried out 1 time in total.
4.3), statistical analysis of data
The combination action type of any two or the mixture of the two and the three on the weeds is evaluated by a Colby method.
And (5) cutting green tissues on each treatment ground in 15 days, weighing by adopting an electronic balance, and calculating the actual survival rate: e (%) × 100 (fresh weight of weeds in treatment area/fresh weight of weeds in control area) × 100
The theoretical weed survival rate calculation formula is as follows: e0 (%) ═ X Y/100 (binary mixed use)
Wherein X represents the survival rate of weeds A at a dose of P, Y represents the survival rate of weeds B at a dose of Q, E0 represents the theoretical survival rate of weeds A + B at a dose of (P + Q), and E represents the actual survival rate of weeds for each treatment.
E0(％)＝X×Y×Z×…×N/100(n-1)(use of three or more elements)
X, Y, Z, N in the formula respectively represents the actual survival rates of n single agents, and n is the number of varieties of the compound herbicide.
When E0-E is more than 10%, the synergistic effect is generated; when E0-E < -10%, antagonism is indicated; when E0-E is within. + -. 10%, it is indicated that an additive effect is produced.
The evaluation statistical results of the actual control effect and the combined action of the mixed components on weeds are shown in tables 1-20.
