芒種(zhong)時(shi)節麥已(yi)成熟，若遇連(lian)雨天(tian)氣，甚至冰雹(bao)災害，會使小(xiao)麥無(wu)法及時(shi)收割(ge)、脫粒(li)而(er)導致倒伏、落(luo)粒(li)、穗上發芽、爛麥場。必須(xu)抓緊一切有利時(shi)機，搶割(ge)、搶運、搶脫粒(li)，“收麥如救火(huo)，龍(long)口把糧奪”正形(xing)象地說明了麥收季(ji)節的(de)緊張氣氛。

民間有“芒(mang)(mang)種(zhong)(zhong)(zhong)(zhong)不種(zhong)(zhong)(zhong)(zhong)，再種(zhong)(zhong)(zhong)(zhong)無用(yong)”、“芒(mang)(mang)種(zhong)(zhong)(zhong)(zhong)插(cha)得是個寶(bao)，夏至(zhi)插(cha)得是根草”這些(xie)諺語，是因(yin)為(wei)夏大豆、夏玉米等夏種(zhong)(zhong)(zhong)(zhong)作(zuo)物的生長期有限(xian)，為(wei)保證到(dao)秋霜(shuang)前收獲，必須(xu)提早播種(zhong)(zhong)(zhong)(zhong)栽插(cha)，才能(neng)取得較高產量。

芒種節氣后雨水(shui)(shui)漸多，氣溫(wen)漸高(gao)，棉花、春玉(yu)米等(deng)春種的莊稼(jia)已進人需(xu)水(shui)(shui)需(xu)肥(fei)與生(sheng)長高(gao)峰，不僅(jin)要追(zhui)肥(fei)補水(shui)(shui)，還需(xu)除(chu)草(cao)和防病治蟲。否則(ze)(ze)，病蟲草(cao)害(hai)(hai)、干(gan)旱、漬(zi)澇、冰雹等(deng)災害(hai)(hai)同時(shi)發生(sheng)或(huo)交替出現，春種莊稼(jia)輕則(ze)(ze)減產(chan)，重則(ze)(ze)絕收。
