The investigation result of each process is shown in following table 1.
The preventive effect to Amaranthus retroflexus is respectively processed after table 1 simulated rainfall
As can be seen from upper table 1, relative to blank, when not carrying out artificially-simulated rainfall, the preventive effect of embodiment of the present invention 1-12 preparation and reference examples 1-3 is suitable.When respectively after treatment 30min, 1h, 2h time carry out artificially-simulated rainfall after, the preventive effect of reference examples 1-3 obviously declines, after carrying out artificially-simulated rainfall during 30min especially after treatment, preventive effect decline especially obvious.And contrary, after artificially-simulated rainfall process, embodiment of the present invention 1-12 preparation to the preventive effect of Amaranthus retroflexus without obvious decline.
Test example 2
For examination weeds: Veronica;
Application method: for each process, is watered dilution spraying by described preparation, each process effective ingredient consumption is 800ga.i./ha, for blank, sprays with equivalent clear water;
Test method: for each process, the respectively laggard row artificially-simulated rainfall when spraying process 30min, 1h, 2h, rainfall standard is 25-30mm, not carry out artificially-simulated rainfall process in contrast, carries out cellar culture afterwards, often processes 3 times and repeats.
Preventive effect is added up: the rear fresh weight preventive effect (mean value) of adding up each process for 10 days of spraying process, circular is
E: fresh weight preventive effect;
C: " blank " weeds acrial part fresh weight;
T: " process " weeds acrial part fresh weight;
The investigation result of each process is shown in following table 2.
The preventive effect to Veronica is respectively processed after table 2 simulated rainfall
As can be seen from upper table 2, relative to blank, when not carrying out artificially-simulated rainfall, the preventive effect of embodiment of the present invention 1-12 preparation and reference examples 1-3 is suitable.When respectively after treatment 30min, 1h, 2h time carry out artificially-simulated rainfall after, the preventive effect of reference examples 1-3 obviously declines, after carrying out artificially-simulated rainfall during 30min especially after treatment, preventive effect decline especially obvious.And contrary, after artificially-simulated rainfall process, embodiment of the present invention 1-12 preparation to the preventive effect of Veronica without obvious decline.
Above-mentioned example is only to further explanation of the present invention, is not limitation of the invention, by the scheme simply adjusted by such scheme and then obtain, equally within the protection domain of the application.
