Apple cockroach control has a coup, spore catcher can be prevented in advance
Apple Alternaria deciduous is an early defoliation disease with a short history and serious harm. The plant disease mainly damages the leaves and causes serious early defoliation, which in turn causes serious economic losses. Therefore, in the cultivation and management of apple orchards, how to strengthen the control of apple spotted leaf disease is one of the most important items. Since the occurrence of apple leaf spotted leaf disease is related to the spores of scattered spores in apple orchards, spore traps have been installed in many apple orchards in order to improve the control effect of apple spotted leaf disease and reduce disease losses in recent years. To collect disease spores can prevent apple deciduous disease in advance and improve the control effect of apple deciduous disease. In general, there are three main methods for preventing and treating apple leaf spotted leaf disease. The first is strict quarantine. Try not to introduce seedlings and scion from the ward; second is to strictly clean the garden. In autumn and winter, the fallen leaves are carefully removed, the diseased branches are cut off, and the burning is concentrated. Before germination, spray 40% of Formamide arsenic wettable powder 100 times, eradicate the source of the disease; the third is prediction. The most common and effective way is to use spore traps for monitoring; the fourth is chemical control. Focus on the protection of early leaves, based on the defense. Spore traps were used to monitor spores. Fixed spore traps were installed in the apple orchard. Mobile spore traps were also used for the detection. Vaseline was applied on glass slides to capture disease spores every 3 days. Change it one time and remove it under a microscope. On the fourth day of the spore peak, the size of the diseased millet grains can be seen; on the seventh day after the peak day, the first spot was found in the field, which should be controlled by drugs. Because apples are for human consumption, spraying a large amount of chemicals can easily cause pesticide residues in agricultural products. Using spore traps for forecasting can help growers to grasp the best timing of medicine, control the amount of medicine, and achieve good results. Therefore, it can be said that the use of spore traps to do forecast work and carry out early prevention are small tricks for the control of apple spotted leaf disease, and it is also an effective way to prevent and control diseases. Therefore, in modern green plant protection work, spores The use of traps has become more and more widespread and more and more important.
For
most car brands, the headlight is just a part of the car, and its meaning is
not much different from other parts, but Audi is different, it has a unique
view on the design of the car headlights.
In the 1990s, like most
car brands, Audi lights used halogen light sources as the main lighting source
for Audi headlights.
At
the North American International Auto Show held in 2003, Audi brought the Pikes
Peak quattro concept car (the predecessor of the Audi Q7). One of the most
prominent designs was to change the round fog lights to narrow strips and
integrate them With the addition of LED light sources, this is the earliest
prototype of daytime running lights.
In
2005, Audi shifted its focus to the taillights and tried to equip the A6 Avant
with LED taillights. Compared with traditional taillights, Audi LED taillights
are better in terms of light source intensity, and can also have extremely high
penetration in extreme weather. Some people even joked a little, "No
matter how far away or how poor the line of sight is, as long as there is a
little light in front, don`t think about it, it must be an Audi car."
Since then, Audi has
been fascinated by "lights", and has gone further and further on the
road of headlight R&D and design, such as Audi LED headlights, Audi dynamic
flow turn signals, Audi laser headlights, Audi matrix headlights, and now Audi
LED matrix laser headlights all reflect Audi's obsession and attainments in the
field of lighting.
