1, different light intensity, yellow LED trapping effect It can be seen from Table 1 that the stronger the light intensity, the more insecticidal effect, the insecticidal effect of the LED insecticidal lamp is higher than that of the corresponding antagonistic yellow smear, and the number of insecticidal lamps hitting the yellow plate is higher than that without killing. The yellow plate of the insect lamp is due to the fact that the insecticidal lamp has increased the insecticidal ability of the part of the yellow scorpion at night, but the nighttime insecticidal effect of the yellow plate is not as good as that of the corresponding LED insecticidal lamp. The stronger the intensity, the better the insect attracting effect. Tests have shown that due to the small area of ​​the insecticidal net, there are many insect sources, and the insects are stuck to the grid after being electrically dead by the grid, blocking the scattering of light. As the duration of continuous use is extended, the number of effective insecticides is significantly reduced, so the grid should be cleaned once after 2 days of continuous use. 2, different color LED lights insecticidal effect By comparing the insecticidal effects of different color LED insecticidal lamps for 2 consecutive days, the green and blue insecticidal lamps have the highest number of insecticides, the yellow insecticidal lamps are the second, and the red insecticidal lamps are the least. It is indicated that the LED light spectrum of the blue and green bands of Liriomyza is the strongest, followed by the yellow spectrum. 3. Control effect on different weeds in grasses Different grass weeds in wheat fields have different degrees of sensitivity to macrogenesis. Look at Mai Niang and Japan to see the sensitive and high activity of Mai Niang; and the sedge and hard grass followed; the head grass can generally control its harm; it has a certain growth inhibition effect on the bluegrass, but the plant does not die. 4, the weeding effect after mixing The combination of Daeneng and isoproteren, Maixi and other herbicides has obvious effects of improving the herbicidal effect of the high-energy herbicide. However, when mixed with the superstar, the effect of high-energy herbicide is reduced, and the increase of the amount of energy can improve the mixed effect. 5, the herbicidal effect of different spray volume The treatment of 22% and 450.0L/hm2 of the medicinal fluid before and after the winter can effectively prevent the grass weeds in the wheat field; while the control effect of the application of 450.0L/hm2 is slightly higher than 225.0L/hm2. Processing area, but the difference is not obvious. 6, the effectiveness of different sprayers on weeds The test results showed that the three kinds of sprayers sprayed with the same liquid amount had good control effect on low leaf age (2~4 leaves) grass, and there was no significant difference. The effect of using high leaf age (5-9 leaves) grass after spring is also similar, and the use of mist machine is slightly worse. Whether this is related to the easy drift of the liquid when the fog machine is applied remains to be further studied. 7. Test on the control effect of older weeds In the first ten days of March, weeding and looking at the booting stage of A. chinensis, and some large grasses were applied with 60.0, 75.0 and 90.0 ml (ai)/hm2, and the herbicidal effect was 86.3%-100.0% after 30 and 60 days, and it was safe for wheat. . encapsulated power transformer,EI low frequency transformer,Industrial transformer,power supply transformer,alarm system transformer IHUA INDUSTRIES CO.,LTD. , https://www.ihua-magnetics.com.jpg)
