The effective maintenance of soil moisture in the tillage layer is conducive to the sprouting and emergence of the crop. The effective soil moisture on the ridge is conducive to the downrooting of the main root system to the deep soil, which can increase the water absorption and utilization, and prevent crop lodging. The effective maintenance of inter-row soil moisture can promote the lateral growth of the crop roots, increase the radius of the nutrient absorption area of ​​the crop, and prompt the crop to rapidly form a huge root structure, which is conducive to improving the resistance of the crop. We used experiments to understand the effect of different treatment of sugarcane leaves on soil moisture. The determination of soil moisture can be determined by a portable soil moisture meter.
Compared with the control incineration process, the soil water content of different sugarcane leaves returned to the field was higher than that of the control treatment during the key agronomical water demand during budding, emergence and late maturation of ratoon cane. The relatively high soil moisture content in ratoon cane leaves is treated with interlacing and returning to the sugarcane leaves. If this sugarcane leaf returning mode is used, the sugarcane leaves scattered in the field should be collected and interlaced after the sugarcane is harvested. place. The soil moisture content in the whole growing period of ratoon sugarcane leaves in the whole growing period of sugarcane leaves was comparable to that of the control treatment. The total coverage of sugarcane leaves could maintain a certain amount of soil moisture, but it had a certain inhibition effect on the sprouting and emergence of ratoon cane. Because sugarcane leaves contain a large amount of phenolic acids and flavonoids, such allelochemicals and autotoxic substances have a strong inhibitory effect on the sprouting of ratoon root buds. However, we usually use multiple soil temperature and humidity recorders to track soil moisture. The multi-point soil temperature and humidity recorder can also provide us with relevant soil temperature information while measuring soil moisture, so that we can better understand the physiological conditions of the soil. Therefore, when implementing full coverage of sugarcane leaves, the sugarcane leaves near the cane must be opened slightly to allow the sugarcane to transmit light to minimize the influence of phenolic acids and flavonoids in the sugarcane leaves. The results showed that the water retention effect in the early stage of row sugarcane leaves and mulching film treatment was better, but the soil moisture in the middle and later periods had a tendency to decrease. This may be due to the fact that degradable plastic film was used in the experiment, and the plastic film was partially degraded in the middle and later stages, resulting in soil The evaporation of water increases. On the other hand, the soil moisture content of sugarcane between rows of ratoon cane was higher than the control incineration during the whole growth period, indicating that the sugarcane rows were locked under the backing sugarcane leaves and locked in considerable soil moisture, which favored the horizontal growth of sugarcane roots. To expand the nutrient absorption area of ​​sugarcane, and at the same time effectively promote the replacement of sugar cane roots.
XS Hub Centric Rings, designed to fill in the gap between the hub of the car and the center bore of the wheel for averting vibration. There ar two kinds of material used, one is PE, another is T6-6061 aluminum.
why Hub Ring? O`Rings / Spigot Rings or Alloy Wheel Hub Centric Rings are designed to
fill in the gap between the hub of the car and the center bore of the wheel.
Most wheel manufacturers design their wheels with a center bore large enough to
fit on most cars. Therefore, since wheel manufactures make their center bore
large enough to fit most cars, most wheel fitments have a gap between the hub
and the center bore.This gap usually doesn't allow for the wheel to fit hub
centric but rather lug centric which causes vibration. Therefore, to fill the
gap and ensure the fitment is hub centric, hub rings are used.
