一、前言稻瘟病往年在湖北省不是个嚴重問題,主要是由于栽种秈稻,而秈稻比較抗病,糯谷虽感病較重,但栽培面積很少,并不引起注意。自大量引种粳稻后,稻瘟病就成为突出問題之一,正因为这是个毁滅性病害,引起党和政府的重视,并領導試驗研究和教学机关共同進行研究,使科学技術赶上客观要求。今年在湖北省很多地方防治了稻瘟病,并取得了粳稻的丰收,但是在另一方面由于技術貫澈不够,也遭受了一定的損失。本文从彙报資料及調查試驗中加以分析研究,找出在湖北地区的發病規律,总結今年的防治技術,提出今后对此病防治的意見,以供参考。
I. Introduction Rice blast is not a serious problem in Hubei Province in previous years. It is mainly due to the planting of indica rice, while indica rice is more disease-resistant. Although waxy rice is more susceptible, the cultivated area is small and does not attract attention. Since a large number of introduced japonica rice, rice blast has become one of the prominent problems, precisely because it is a devastating disease, causing the party and government attention, and led the pilot study and teaching organs to conduct joint research so that science and technology catch up with the objective requirements. This year, prevention and control of rice blast in many places in Hubei Province have been achieved and the harvest of japonica rice has been achieved. However, on the other hand, due to insufficient technology, it has also suffered some losses. This article analyzes and studies from the reported data and investigation and experiment to find out the law of onset in Hubei Province, summing up the prevention and treatment technology of this year and putting forward the opinions on the prevention and treatment of this disease in the future for reference.
