Prescription method is shown in 2.3.2, uses stem and leaf facture.
4) data survey and statistical analysis
4.1), investigation method
Use absolute number survey method, cut off survival weeds whole strain seedling with blade along soil surface, weigh with analytical balance
Weeds fresh weight.For dead weeds, it is based on zero by fresh weight.
4.2), control time and number of times
Process investigation in latter 20 days, altogether investigation 1 time.
4.3), data statistic analysis
With Gowing method calculate each process hybrid combining theoretical fresh weight inhibition (E0=X+Y-X*Y/100), then with
Actual measurement suppression ratio (E) compares, and evaluates the two mixed synergy type to weeds, when E-E0 value is made for potentiation more than 10%
With, less than-10% be antagonism, being addition between-10%～10%.And it is special according to actual preventive effect and herbicide
Point, the factor such as balance of formula determine optimum proportioning.
In formula X be A consumption be fresh weight inhibition during P；Y be active component B consumption be fresh weight inhibition during Q.
Statistical result see table.
