植物病害是农业生产的大敌,防治植物病害是夺取农业丰收的重要战斗任务。植物病害种类繁多,为害情况也很复杂。如果对植物病害在田間为害的情况和发生发展的规律没有很好了解,就无法进行适时有效的防治。有些病害的病原可能我們还不了解,或者病害的侵染循环我們还没有搞清楚,必須通过試驗研究加以確定,才能对症下药。为了帮助基层讀者在科学实驗的革命运动中开展植物病害的调查研究工作,我們将在本栏陆續发表一些文章,簡单介紹植物病害调查研究的基本方法,以供参考。
Plant disease is the enemy of agricultural production. Plant disease control is an important combat task to seize the agricultural harvest. A wide range of plant diseases, damage situation is also very complicated. If the plant diseases in the field damage and the occurrence and development of the law is not well understood, it can not be timely and effective control. We may not know the pathogen of some diseases or we have not figured out the infection cycle of the diseases and we must make sure through the experimental research that we can make the right remedy. In order to help grass-roots readers carry out investigation and research on plant diseases in the revolutionary movement of scientific experiments, we will publish some articles in this column one after another to briefly introduce the basic methods of plant disease investigation and study for reference.
