在英明领袖华主席的亲切关怀和支持下,我国杂交水稻在大发展。突破、实现了“三系”配套,并开始应用于大面积生产,取得显著成绩,为粮食大幅度增产,开创了又一新途径。现在一个群众性种植杂交水稻的高潮已经掀起。我省今年杂交水稻种植面积预计在250万亩左右。生产实践证明,杂交水稻生长优势强,基秆粗壮,叶色深绿,穗大粒多,产量高,我省最高单产达1400多斤。但杂交水稻,特别是当前移植面积较大的“闽优一号”等杂交组合,不抗白叶枯病,大流行率可能导致严重减产。因此,抓好以白叶枯病为重点的病虫防治工作,是夺取今年杂优水稻高产的重要保证。根据全国水稻白叶枯病综合防治会议精神和我省的防治经验,提出杂优水稻白叶枯病的防治意见如下:
Under the gracious care and support of Chairman Hua, wise leader, the hybrid rice in our country is undergoing great development. A breakthrough has been achieved in supporting the “three lines” and starting to be applied to large-scale production with remarkable achievements. This has opened up a new avenue for the substantial increase of grain output. Now a climax of mass planting of hybrid rice has been set off. The province of hybrid rice planted this year is estimated at about 2.5 million mu. Production practice has proved that hybrid rice has strong growth advantages, stalks stout, dark green leaves, spike large grain, high yield, the highest yield of our province up to 1400 kilos. However, the hybrid rice, especially the current hybrid rice combination “Min You 1” which is larger in area, is not resistant to bacterial leaf blight and the pandemic rate may lead to serious yield reduction. Therefore, doing a good job in pest control focusing on bacterial leaf blight is an important guarantee to seize this year’s high yield hybrid rice. According to the national conference on rice bacterial leaf disease prevention and control and our province’s prevention and control experience, put forward hybrid rice bacterial leaf blight control views are as follows:
