荞麦是最喜温作物之一,它的生物学特性与北方许多作物不同。与温度的关系:荞麦在生长发育期间需要很高的温度,当温度在7～8℃时开始发芽,但是在13～15℃情况下幼苗才能正常发育。出苗的最适宜温度为15～30℃。播种到出苗期间遇到低温是降低产量的主要原因之一。温度在16℃以上才能形成植株的繁殖器官。在出苗期间,如果天气变冷会使荞麦苗大量死亡。1981年在呼和浩特郊区榆林公社苏木沁大队,不同时期播
Buckwheat is one of the most warm crops, its biological characteristics and many different crops in the north. Relationship with temperature: Buckwheat during growth and development needs a high temperature, when the temperature at 7 ~ 8 ℃ began to germinate, but in the case of 13 ~ 15 ℃ seedlings to normal development. The most suitable temperature for emergence is 15 ~ 30 ℃. Encountering a low temperature during sowing is one of the main reasons for reducing production. The temperature above 16 ℃ to form the plant’s reproductive organs. During the emergence period, a large number of buckwheat plants die if the weather becomes cold.
