上杭县古田基点——溪背大队,春暖迟,秋寒早,原属单季稻区。无产阶级文化大革命后,抓革命,促生产,贯彻“以粮为纲,全面发展”的方针,实行科学种田。几年来,大力推广双季稻,普遍种植矮稈良种,获得了年年增产。由于耕作制度的变革,品种的调换,水稻主要病虫害发生发展的规律也相应起了变化。比如,山区以往发生较普遍的负泥虫、稻食根金花虫,稻胡麻叶斑病等日趋减少,而稻瘟病、稻螟、稻飞虱、叶蝉类、稻纵卷叶螟等为害逐渐加剧。早季以稻瘟病为害较重,晚季以稻螟、稻飞虱、叶蝉类为害最烈。为了确保今年粮食上《纲要》,在防治水稻病虫害工作上,要切实执行“预防为主,防治结合”的方针,在战略上要藐视它,在战术上要重视它,力争把它消灭在发生危害之前,勿使蔓延成灾,造成不应有的损失。 Gutian, Shanghang County base - Creek back brigade, late spring, early autumn cold, originally a single season rice area. After the great proletarian cultural revolution, we must grasp the principle of revolution, promote production, and implement the principle of “taking grain as the key link and all-round development” and carry out scientific farming. In recent years, vigorously promote double cropping rice, dwarfing common planting, access to annual yield. Owing to the change of farming system and the exchange of varieties, the law of the occurrence and development of major rice diseases and pests also changed correspondingly. For example, in the past, mountainous area occurred more common negative insect pests, rice root goldenrod, rice flax leaf spot and other declining, and the rice blast, rice stem borer, planthoppers, rice leaf roller and other damage Gradually intensified. In the early season, the damage to rice blast was heavier, and in the late season, rice borer, rice planthopper and leafhopper were the most damaging. In order to ensure the “outline” of food this year, we must earnestly defy the principle of “prevention first, combine prevention with prevention” in the prevention and control of pests and diseases of rice, pay attention to it tactically, and strive to eliminate it In the event of harm, do not let the spread of disaster, resulting in undue losses.
