Since July 11, there have been many thunderstorms in Beijing. From the afternoon of the 24th, the Beijing area has experienced heavy rains from west to east. The heavy rains have continued from day to night and will turn into small to moderate rain this morning. As of 22:00 yesterday, the average precipitation in Beijing was 52 mm, and the maximum precipitation occurred in Shunyi, which was 172 mm. The Beijing Meteorological Bureau launched a heavy rain level III emergency response.
It is estimated that in the next 7 days, there will still be more rainwater in Beijing. The total rainfall is 70-90 mm, and the local area can reach 100-160 mm. The rainfall in most areas is slightly more than normal, and the local area is more than 50%. Times. There are two main rainfall processes: around the 25th, there is moderate to heavy rain in Beijing, heavy rain in some areas, and short-term thunderstorms and strong winds; from 28th to 29th, there is moderate rain in Beijing, and heavy rain or heavy rain in some areas. .
As there are still rainy weather in Beijing in the next few days, the inspection, consolidation and drainage of water conservancy facilities such as river embankments and reservoirs should be strengthened. At the same time, attention should be paid to flood control and drainage in the process of heavy precipitation to prevent or mitigate the adverse effects of heavy precipitation on agricultural production. Drainage work in crop fields, especially in low-lying areas, should be carried out to prevent crops from being flooded. All localities should promptly carry out post-disaster agricultural production recovery and remediation work. For crops that have been harvested, other crops should be replanted in time, and crops that are less affected by light should be cleaned and seeded, and soil fertility should be promoted in time to promote their recovery. Timely support the vegetable plant. It is necessary to correct the lodging of the vegetables, reduce the phenomenon of mutual extrusion, and properly cultivate the roots. Timely cultivating loose soil. After the rain, the soil is compacted. When the soil is slightly dry, the soil is ploughed to improve the soil structure, improve the root activity, and promote rain-proof cultivation. Covering the top of the greenhouse with plastic film, shading net and other materials can not only avoid the direct germination of rainwater, but also effectively improve the temperature, light, humidity, gas and other microclimates in the shed, and reduce the number of chemical control and the amount of drug used. The crops that are flooded with sweet potatoes, peanuts, soybeans, vegetables, etc. should be cleaned and drained in time, cleaned with mud, washed with soil, fertilized and fertilized, and promoted to restore growth. Crops that have been harvested should be replanted or replanted in time. In the orchard where the disaster is lodging and the branches are broken, it is necessary to carry out the clearing of the garden in time, remove the sundries, strengthen the tree body and cultivate the soil to increase the fertilizer, and the roots are severely damaged. At the same time, China Xingnong.com recommends that the rainwater resources be collected and comprehensively utilized in the near future.
Farmland submerged by heavy rain
Water soluble β- Cyclodextrin Polymers were prepared from β-cyclodextrin crosslinked with epichlorohydrin under basic conditions. The influence of preparation conditions on the molecular weight distribution has been investigated. The knowledge of this relationship allows for the choice of reaction parameters according to the desired weight distribution of the β-cyclodextrin polymer. A procedure was developed for the preparation of high molecular weight water soluble polymer
