、低di溫wen霜shuang凍dong。早zao稻dao育yu秧yang期qi間jian如ru遇yu較jiao強qiang冷leng空kong氣qi侵qin襲xi，就jiu有you可ke能neng出chu現xian低di溫wen霜shuang凍dong，極ji易yi造zao成cheng秧yang苗miao凍dong害hai，甚shen至zhi死si苗miao。對dui低di溫wen霜shuang凍dong的de預yu防fang，可ke在zai冷leng空kong氣qi來lai臨lin前qian夕xi
，采cai取qu灌guan深shen水shui保bao溫wen的de措cuo施shi，即ji灌guan水shui至zhi秧yang苗miao芯xin葉ye，待dai氣qi溫wen回hui升sheng後hou再zai落luo幹gan，恢hui複fu正zheng常chang管guan理li。如ru果guo低di溫wen時shi間jian較jiao長chang，在zai中zhong午wu氣qi溫wen相xiang對dui較jiao高gao時shi可ke適shi應ying排pai水shui通tong氣qi，然ran後hou再zai換huan成cheng新xin鮮xian水shui進jin行xing保bao溫wen。?
　　二、長chang期qi陰yin雨yu。早zao稻dao育yu秧yang期qi間jian往wang往wang雨yu水shui較jiao多duo，光guang照zhao偏pian少shao，氣qi溫wen也ye較jiao低di，有you時shi甚shen至zhi會hui出chu現xian長chang時shi間jian的de低di溫wen陰yin雨yu，容rong易yi造zao成cheng早zao稻dao秧yang苗miao黃huang枯ku，出chu現xian大da麵mian積ji的de料liao秧yang死si苗miao。遇yu到dao這zhe種zhong天tian氣qi，應ying增zeng施shi一yi些xie灰hui雜za肥fei作zuo秧yang田tian覆fu蓋gai物wu
，盡jin量liang少shao灌guan水shui上shang秧yang板ban。但dan在zai久jiu雨yu天tian氣qi突tu然ran暴bao晴qing時shi，則ze應ying適shi當dang灌guan深shen水shui護hu苗miao，防fang止zhi秧yang苗miao出chu現xian生sheng理li失shi水shui而er造zao成cheng青qing枯ku死si苗miao。?
