4.3 data statistic analysis
Each theoretical fresh weight survival rate rate for processing hybrid combining is calculated with Colby methodsSo Afterwards compared with actual measurement survival rate rate (E), the mixed synergy type to weeds of three is evaluated.When E0- E value less than -10% be antagonism, more than 10% for synergistic effect, between -10%～10% For addition.And determined most according to the factor such as actual preventive effect and herbicide feature, the balance of formula Good proportioning.
Fresh weight survival rate when X is P for sulphonyl triazolone consumption in formula；Y is for mesotrione consumption Fresh weight survival rate during Q；Fresh weight survival rate when Z is R for atrazine consumption.
Statistics is shown in Table 1.
5 interpretations of result and discussion
5.1 evaluating drugs
Synergy type：Result of the test shows (table 1)：Sulphonyl triazolone, mesotrione and green bristlegrass Tianjin is gone to use survival rate and theoretical survival rate difference (E-E of each combined treatment to 2 kinds of weeds with0) be on the occasion of, Illustrate that three pharmacy mix can improve preventive effect, each combined treatment E-E0Value is above 10%, illustrates that three mixes With belonging to synergistic effect.
Optimum proportioning determines：As it can be seen from table 1 in 8 proportionings, respectively combining to 2 kinds of weeds Preventive effect is higher.From preventive effect and cost consideration, with sulphonyl triazolone+mesotrione+atrazine= 75+75+750 or 75+75+900g/hm2It is mixed even more ideal.That is sulphonyl triazolone：Mesotrione： The proportioning of atrazine is 1：1：10 or 1：1：12 and its more suitable nearby.
When it is determined that total content is 30% suspending agent, sulphonyl triazolone+atrazine+mesotrione= 2.5%+2.5%+25% is more reasonably to select.
The sulphonyl triazolone of table 1, the mesotrione actual preventive effect and connection to weeds mixed with atrazine Close action effect (Colby methods)
