摘 要:本文重点是阐明“七·五” 期间多功能新技术的研究、评价和利用。包括:高产多抗新品种10个,应用面积近千万亩;新一代昆虫生长调节剂扑虱灵,推广面积达一千万亩;将控害措施融合到高产栽培中,形成了高产控害栽培的新技术;从实际出发,研制出纹枯病与褐稻虱等一批多病虫复合防治指标;已检测出白叶枯病菌菌系群及稻瘟病小种群的变化动态及分布;最终,根据地区特征,建成江淮稻区病虫综合防治区域模式。In this paper, we set the Yangtze-Huai rice production region as an example and sumed up the new development of integrated pest control(IPC) on rice in recent years in China. In our research, the effective approaches of IPC are natural control which is taken as major parts and the artificial regulation as assistant parts. Our research work from 1986-1990 was focussed on exploitation, evaluation and utilization of multi-function or multi-effectiveness control techniques. The main contents of the systems are as follows:1. Evaluation and utilization of resistant varieties have been made great progress. More than 10 resistant varieties which possess high yield potential and grain quality, and double or multiple resistance to diseases and insect pests, such as NANJING 14, YANGDAO No.3, SHANYOU 63 etc., are recommended for commercial production with growing area over a million hectares.2. It is great successful in exploitation of new chemical generation to control pests, such as PUSELING, which is a new chitin synthesis inhibitor of insects. Spraying only once could depress the population of brown planthopper in the whole growing season of rice. The application areas of this chemical are over a million hectares in China.3. Based on the rule of occurrence of diseases and pests in rice, improvement of cultural practices are combined with the high yield cultural plan to ensure healthy plant grouwth. Corresponding fertilizer and water control measures are adopted to prevent and lessen damage and give full play to fertilizer and water control. The pressure on chemical control can be reduced.4. An index of multiple-species control thresholds for major diseases and insect pests in rice which could raise comprehensive extent of IPC have been drawn up.5. The distribution and variation dynamics for physiological races of Pyricularia oryzae Car. including B.C.D.E. groups have been researched. The seven bacterial pathotypes (or races) of Xanthomonas campestris pv. oryzae in China are divided into sevsen bacterial strain groups acc
