  • Detail

The 556000 mu of rubber in Xishuangbanna was affected

according to the official and enterprise data of Xishuangbanna Prefecture in Yunnan, the second largest rubber production area in China, 10% - 15% of the rubber planting area and production were affected and reduced in the continuous drought. If the rainfall from April to May was timely, the rubber production can still be guaranteed

as of March 24, the affected area of rubber in Xishuangbanna was 556000 mu, and the corresponding wear amount converted from the disaster area was 56100 mu. Zhou Hai, chief of the planting section of Xishuangbanna Agricultural Bureau, said that the rubber planting area in the whole Prefecture is 3.82 million mu. Based on this calculation, the rubber affected area and the affected area account for 14.6% and 1.5% of the total respectively. Zhou Hai said that the rubber disaster refers to the possibility of reducing production or delaying rubber cutting. The disaster means that the rubber basically fails to harvest or withers

muhongjun, director of the science office of Yunnan Institute of Tropical Crop Science, said: "Xishuangbanna rubber is less affected by the drought. The local rubber forest produces 110 kg of rubber per mu, which is the highest in the country. This year's drought has two main effects on rubber production. One is the delay of rubber cutting time. In normal years, the leaves of rubber trees gradually age from March, and after about 20 days, rubber cutting begins. This year, due to water shortage, the aging time of rubber leaves is postponed, and the rubber cutting time is also postponed accordingly; The other is the increase of insect pests. According to our observation, there are four tolerances in the table of rubber scale insects and six points. The number of leaf mites is higher than that in previous years. "

Yunnan Xishuangbanna Jinghong farm is the second largest local rubber plantation, with about 160000 mu of rubber forest, and the number of rubber trees exceeds 3million. Speaking of the losses caused by drought, Chen Kenan, member of the Standing Committee of the Party committee and deputy manager of Jinghong farm and Yunnan Natural Rubber Industry Co., Ltd., said that Jinghong branch of Jinghong farm was an early branch in Xishuangbanna Agricultural Reclamation Bureau, Some other branches of the Agricultural Reclamation Bureau have not started tapping due to the drought

Chen Kenan said that compared with the same period last year, the dry rubber production of Jinghong farm decreased by about 500 tons, with a loss of 10million yuan calculated at 20000 yuan per ton. According to the introduction of Jinghong farm, the production of raw rubber in the whole farm was about 80 tons per day in previous years, but now it is about 70 tons, a decrease of 12.5%

Chen Ke can't say that due to water shortage, rubber trees can't stretch their leaves, and the other is that they only bloom without leaves, so they can't carry out photosynthesis. The stimulants that catalyze rubber production of rubber trees dare not be used, which is the main reason for the reduction of production. Most rubber trees in Jinghong farm are located in mountainous areas, and the number is huge. Artificial irrigation and water replenishment is unrealistic, and the water needed by rubber trees can only depend on nature. In addition, Xishuangbanna is clay, and long-term drought will lead to the loss of soil viscosity and desertification. Rubber trees are tall trees. In case of sudden heavy rain, rubber trees may overturn and overturn their roots, which is another potential risk brought by drought

Mu Hongjun introduced that Yunnan produces more than 200000 tons of rubber every year, 80% of which comes from Xishuangbanna. At present, although the production of fatigue testing machines is also reduced, may is the peak period of rubber cutting in Xishuangbanna. As long as the rainfall from April to May is timely, the rubber output can still be guaranteed
