小麦种子发芽的适宜温度为20—25℃.我省7、8月间的室内温度,一般为30—35℃,这时做发芽试验,如用一般方法,便不能准确的测出其真实发芽率.1979年7—8月,我们根据保温瓶可以保温(保冷)及冰棒融解或汽化需要吸收熔解热80卡/克与汽化热595卡/克的原理,创用了简易控温法测小麦发芽率,其最高的发芽率达到或超过了95％,比室温发芽率高出19.8％—43％.近几年来,在湖北咸宁、嘉鱼、崇阳及河南许昌等县引进 Wheat germination suitable temperature is 20-25 ° C in our province in July and August, the indoor temperature, usually 30-35 ° C, then do germination test, as with the general method, it can not accurately measure the true germination 1979. From July to August of 1979, based on the principle that the thermos can be insulated (cold) and the popsicles melt or vaporize and need to absorb the heat of fusion of 80 calories per gram and the heat of vaporization of 595 calories per gram, a simple temperature-controlled method of measuring wheat Germination rate, the highest germination rate reached or exceeded 95%, higher than the germination rate at room temperature 19.8% -43% .In recent years, in Xianning, Jiayu, Chongyang and Henan Xuchang County introduced
