糜子是喜温作物,对温度反应十分敏感,它在整个生育期间都需要有较高的温度。据我所试验,当5厘米深的地温,日平均在12.7～16.7℃时,播种后11天出苗,日平均温度上升到16.8℃时,播后8天出苗,达19.3～24.9℃时,6～7天出苗。日平均气温在19℃以下时幼苗生长缓慢,在22～24℃时生长最快。开花期的日平均气温低于17℃时影响授粉,结实率很低。糜子在20℃以上时播种,生育期显著缩短,特别是出苗至抽穗的日期缩短很多,影响穗部性状和产量。所以
Millet is a thermophilic crop that is very sensitive to temperature and requires a high temperature throughout its growth. According to my test, when the ground temperature is 5 centimeters deep, the average daily temperature is 12.7 ~ 16.7 ℃, the seedlings emerge 11 days after sowing, when the average daily temperature rises to 16.8 ℃, the seedlings emerge 8 days after sowing, reaching 19.3 ~ 24.9 ℃ ~ 7 days of emergence. When the average daily temperature is below 19 ℃, the seedling grows slowly and grows fastest at 22 ~ 24 ℃. The average daily temperature at flowering less than 17 ℃ affect pollination, seed setting rate is very low. When millet is sown above 20 ℃, the growth period is significantly shortened, especially the date of emergence to heading is shortened, and the ear traits and yield are affected. and so
