According to the area of experimental plot, the good various medicaments of precise, and be watered after dilution, using knapsack sprayer, Carry out even spraying, the special Fan spray head of sprinkler selection herbicide.During spraying, it should be noted that decoction is uniformly sprayed application to experiment small Qu Zhong, accomplishes the phenomenon sprayed without drain spray, more.20d, 40d observe weeds death condition after medicine respectively after experiment, and relatively more each The activity of weeding of medicament is planted, 4,5 are specifically shown in Table in addition, the condition of production of crop is also observed in 1-15d after medicine, to investigate medicine Whether agent has poisoning to crop, is specifically shown in Table 6.
Effect of the table after 4 20 days
Effect of the table after 5 40 days
As can be seen that the present invention is used by three kinds of active ingredient mixtures from table 4,5, closing is two-tube neat with cauline leaf process Under, make the rapider of its drug effect performance, the preventive effect to barnyard grass, moleplant seed, water amaranth, rhizoma alismatis, cyperus iria, difformed galingale herb is higher than The preventive effect that agricultural chemicals is used alone, at the same to grass family, broad-leaved section, overall also above the three kinds agricultural chemicals of preventive effect of sedge weed individually or The overall preventive effect of any two kinds of compounding uses, achieving significant synergistic effect, there is provided overall preventive effect so that the present invention Herbicide controlling spectrum further expand.The herbicide medication of the present invention simultaneously is substantially better than two kinds of agricultural chemicals lists after 20 days with drug effect after 40 days The prevention effect solely used, this show the present invention herbicide not only act on more persistently, and be difficult so that weeds especially Malignant weed develops immunity to drugs.
Table 6 is to crop rice safety sex investigation
Table 6 shows that the rice seedlings that herbicide of the present invention is respectively handled in cell grow fine, and has no any obvious medicine spot, explanation The herbicide of the present invention is safe to paddy rice.Herbicide of the present invention is easily degraded, to rice safety, is had no side effect；In soil Middle residual life, is short, to succession crop safety.
It is known that the illustrative embodiments that above-described embodiment uses only for explanation inventive principle, but it is of the invention This is not limited only to, those skilled in the art can make various improvement and change in the case where not departing from real situation of the present invention, these Improve and change falls within protection scope of the present invention.
