It is estimated that before September 10, Anhui Province will be dominated by rainy weather. The precipitation will be obvious around the 8th, and heavy rain will occur in some areas. The precipitation will basically end on the 11th to 12th, but the province is still dominated by cloudy to cloudy weather. From June to August, most of Hubei Province experienced a moderate-intensity precipitation and temperature-cooling process from west to east. From 9 to 14 days, it was affected by high-altitude fluctuations and cold air southward. Most of the province's areas were cloudy and rainy. On the 5th to 7th of September, precipitation weather occurred in the eastern part of Heilongjiang Province. The precipitation process eased the drought of some soils in the dry land, but the precipitation process was accompanied by cloudy and cloudy weather, and the sunshine was less, which was not conducive to crop filling and grain dehydration. .
In the next few days, Anhui Province will continue to be dominated by rainy weather. As most of the crops are in the late stage of maturity, the occurrence of continuous rainy weather in this period has a greater impact on the yield and quality of crops. Rainy weather will delay the maturity of the crops, leading to late crop maturity; short-term guilt in areas with large rainfall, causing hypoxia in crop roots, easy detachment of cotton buds, lodging of tall crops and weak stems; The increase in crop pests and diseases will eventually lead to a decline in crop yield and quality. In order to alleviate the harm of rainy weather and autumn harvest crops, it is necessary to arrange labor reasonably, strengthen field management, clean up the three ditch in time, eliminate the water accumulated in the field, and reduce the soil moisture; the cotton area should grab the cotton that has been spun cotton in time before raining. Ventilation and light transmission of cotton, corn and other crop fields; at the same time, we must pay close attention to the dynamics of pests and diseases, rational use of drugs, active prevention and control, minimize losses, and ensure a bumper harvest.
Continued illuminating of the fish pond will result in weak photosynthesis of phytoplankton in the water and insufficient oxygen production, resulting in insufficient dissolved oxygen in the breeding environment. In addition, the fish density is high, and the phenomenon of fish anoxic floating head or even pan-yellow is very likely to occur. The fish ponds in Jingzhou and other places in Jianghan Plain have experienced serious floating heads in the fish ponds from the night of September 6 to the morning of the 7th. Suggestions for this:
1. The fish caught in the specifications will be listed in time to reduce the breeding density and reduce the water load.
2. For aquaculture waters such as ponds where oxygen deficiency has occurred, use an aerator to increase oxygen or pump water to aerate oxygen; or use oxygen in oxygen cylinders to oxygenate fish in cages and high-density fish ponds through plastic pipes. .
In the Heilongjiang area, there are many cooling weather after the rain, so you need to pay attention to the preparation of low temperature and frost protection. It is suggested that farmers should strengthen field management and do a good job in promoting early maturity. Appropriate irrigation of rice, keep the mud temperature, make the grain more full, reach full maturity; soy leaves to promote ripening; corn adopts the measures of drying the skin to reduce the grain water content and improve the quality of corn; can appropriately increase the leaf fertilizer beneficial to crop maturity And growth regulators that extend the photosynthesis time of functional leaves.
Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
