绵竹县位于四川平原,都江堰灌区尾水,盛产水稻、晒烟。长期以来,春烟生长季节气温偏低(3、4月份的月平均气温分别为11.3℃、16.1℃),降雨量少(3、4、5月份降雨量分别为29.8mm、57.8mm、78.2mm),灌区水源不足,常年农民种烟,都要多浇灌水、肥3—4次。尽管费力大,投资多,晒烟仍然生长缓慢,以致拖长生育期,使后作水稻不能
Mianzhu County is located in Sichuan Plain, Dujiangyan irrigation tailwater, rich in rice, sun-cured tobacco. For a long time, the temperature of spring growing season was low (monthly mean temperature in March and April was 11.3 ℃ and 16.1 ℃ respectively), and the rainfall was small (the rainfalls in March, May and May were 29.8mm, 57.8mm and 78.2mm respectively ), Inadequate irrigation water, perennial farmers grow tobacco, should be more irrigation water, fertilizer 3-4 times.
