云南省许多地区雨量多、湿度大,尤其滇南一些地区,每年5～10月的降雨量,几乎占全年的90%,一般达1350mm以上,且此季又正为高温季节,给种子的收获贮藏造成了极大的威胁。一些地方种子部门,因为无能按种子安全水分保存,致使在贮藏过程中,种子品质受到极大破坏,造成很大的经济损失。如思茅地区原种场,1981年因干燥不及时,损失西南175水稻种子10多万公斤。根据不完全统计,全省每年至少有200万公斤种子受到霉烂出芽和虫害的威
In many parts of Yunnan Province, there is more rainfall and humidity, especially in some parts of southern Yunnan. Rainfall from May to October each year accounts for almost 90% of the whole year, generally reaching over 1350mm, and this season is again for the hot season, Harvest storage poses a great threat. Some local seed departments, because of their inability to preserve seed-safe moisture, have caused tremendous damage to the quality of the seeds during storage, resulting in significant economic losses. Such as the Simao region of the original species field, due to lack of drying in 1981, Southwest 175 lost 100000 kilograms of rice seeds. According to incomplete statistics, at least 2 million kilograms of seeds in the province are affected by mildew and pests
