Severe weather has seriously affected the supply of domestic natural rubber. In the two major producing areas in China, Yunnan experienced severe drought, and Hainan suffered heavy rain, resulting in reduced production of rubber. Moreover, the heavy rain in Hainan has not yet completely stopped, and the number of losses is still expanding.
The drought at the beginning of the year led to a decrease in rubber production in Yunnan. Since September 2009, the precipitation in Yunnan Province has been significantly reduced, and high-temperature, low-rain weather has continued. By the end of March 2010, precipitation in the whole province was 59% less than the same period of the normal year, and the precipitation volume had the record with the least history since 1961. The impact of drought on the cutting of the Xishuangbanna planting area was delayed by about 10 to 15 days compared with previous years. In the absence of rainfall, forcible cutting causes the gum trees to lose glue after they flow out of the glue, resulting in leaf shrinkage and even the death of the rubber tree. Only a third of the normal years are less than the output of the partially cut farms.
In addition, the annual rubber planting in March is an effective measure to increase production and improve the wintering capacity of rubber trees in the Yunnan reclamation area. Due to the lack of water, the technology could not be carried out normally, which also has a great impact on rubber production. The continuous drought has caused 2.51 million mu of rubber in Yunnan's reclamation area to be affected to varying degrees. Yunnan farming reclamation projected that the annual dry rubber production loss will reach 20,000 tons.
Since October, the torrential rain has caused an overall impact on Hainan's agriculture. The areas with the most severe rubber disasters were mainly distributed in the cities of Wenchang, Qionghai and Wanning in the east. The disasters in the central and western regions were relatively light. The Agriculture Department of Hainan Province stated that heavy rains delayed the cutting and that other lodgings and immersions took place to varying degrees. In addition, as of the 9th of October, the natural rubber private sector in Hainan Province has been completely shut down, and the total production has been reduced by more than 10,000 tons. With regard to the agricultural reclamation system, rubber has been completely shut down, and the total production of dry rubber has been reduced by more than 10,000 tons. Hainan's natural rubber planting area has reached 6030000 mu, dry glue output is 248,000 tons, accounting for 47% of the country's total output. The reduction in production has a serious impact on the national supply.
In recent days, Hainan was hit by heavy rain. At 13:00 on October 16th and 13:00 on the 17th, the average rainfall of all the cities and counties in the entire island was 79.7 mm, of which precipitation occurred at 100 mm above the representative stations of 6 cities and counties, and the largest precipitation occurred at the south farm of Qiongzhong, reaching 268.7 mm. From the night of October 17 to the day of the 18th, there were heavy rains in the northern and eastern parts of Hainan Province, with heavy rains in some areas, heavy rains in the central and southern regions, heavy rains in some areas, moderate to heavy rain, and heavy rain in the western regions. In the next few days, the super typhoon "Catfish" will enter the eastern sea of ​​the South China Sea. The Hainan Meteorological Observatory has issued strong wind warnings and super typhoon news. Heavy rain will come again. Most of the rubber production in Hainan in October was the highest peak of annual production. By December, the rubber production volume soon fell to around 1/3 in October. Therefore, multiple rounds of heavy rainfall seriously affected the annual supply level.
Affected by severe weather, the total output of Hainan and Yunnan dropped by more than 40,000 tons, a decrease of 6% compared to 2009.
