Since July, the South 19 provinces (autonomous regions and municipalities) of high temperature weather, an area of ​​3,177,000 square kilometers. According to the China Meteorological Administration, expected in the next 10 days will continue in most areas south of a large range day maximum temperature exceeded 35 ℃ hot weather. Continued hot dry weather, right adversely affect crop growth and development, especially for the heading and flowering in rice and corn tasseling silking cause thermal damage. In this regard the Ministry of Agriculture attaches great importance to and issued "the General Office of the Ministry of Agriculture to prevent heat injury on the good work of the emergency notice", requiring a solid job in the agricultural sector at all levels of heat injury prevention.

Request of the Ministry of Agriculture, First, attach great importance to early arrangements. The impact of heat injury has a hidden and hysteresis. All localities should attach great importance to prevent heat injury as an important task of the current autumn grain production, early arrangements, extensive mobilization launched, the implementation of key measures, to do preventive work. The second is to strengthen the monitoring and timely dissemination of early warning information. Localities should strengthen consultation with the meteorological department, pay close attention to sustained high temperatures and the occurrence of regional and accurately grasp the process of crop growth and development, scientific judgments, and timely dissemination of early warning information to prevent heat injury well ahead of the preparation. Third, strengthen the guidance, promote scientific disaster. Depending on soil moisture and crop growing process, because due to the implementation of good anti-heat injury of technical measures. Rice focused on the implementation of two key technical measures: timely watering, increasing humidity field. Generally have water of rice paddies, canopy temperature lower than the temperature 1-2 ℃. Right at the booting to heading and flowering terraces, field maintained 5-8cm aqueous layer to reduce the spike layer temperature, increasing humidity field. Water drought plots to early for irrigation to prevent drought and heat injury superimposed effect. Foliar spraying, enhance plant resistance to high temperature capability. Heading and flowering in rice before spraying potassium dihydrogen phosphate and fertilizer, increasing canopy humidity, high temperature enhanced the ability of the blade. Lesser evil for booting heated terraces, fill in before and after the break to recover a Postheading, improve seed setting rate and grain weight. Moisture corn to timely irrigation complement and enhance high temperature capability, prevent "card neck drought." Quefei plots to seize the dressing. Meanwhile, we should strengthen the pest monitoring and early warning, and vigorously promote the anti-rule, to prevent and control diseases and insect pests of rice and corn, and "insect population take food." Fourth is to strengthen guidance services, to promote implementation of the measures. Experts and technicians went to the fields, checking Miao Qing, moisture, depending on the crop growth process to develop a comprehensive technical solutions to prevent heat injury. On key areas, including films to take the form of an extended stay, villages and peasant households to guide farmers from place to place because due to moisture in the implementation of field management measures to promote normal growth and development of crops.
