秋风就是在秋初由于冷空气南下,出现对水稻抽穗扬花有影响的低温并常伴阴雨的天气。在我省大部分地区,这种天气常出现在“立秋”之后,故称之为秋风。为了战胜秋风危害,以保水稻丰收,本文针对秋风对水稻的危害及其在我省出现的气候规律,进行了初步分析,并提出一些御防秋风的措施和方法。(一)秋风对水稻的危害水稻是喜温作物,在抽穗扬花期间对环境条件的反应特别敏感,据研究此期适宜的农业气象指标是:温度25～30℃,相对湿度70～80％,微风,日照充足。如遇低温、阴
Autumn is the beginning of the fall due to cold air south, there is the impact of heading and flowering of rice cold and often accompanied by rainy weather. In most parts of our province, this kind of weather often appears after “establishing autumn”, so it is called the autumn wind. In order to overcome the harmful effects of the autumn wind and ensure the harvest of paddy rice, this paper conducted a preliminary analysis on the hazards of the autumn wind to rice and the climate laws in our province and put forward some measures and methods to prevent the autumn wind. (A) the impact of autumn wind on rice Rice is a thermophilic crop, during the flowering and flowering of the response to environmental conditions are particularly sensitive, according to the study of the appropriate agricultural meteorological indicators are: temperature 25 ~ 30 ℃, relative humidity 70 ~ 80% Breeze, plenty of sunshine. In case of low temperature, overcast
