水稻是一种喜温作物,它的生长发育与温度关系极其密切。研究水稻发育转变与温度条件的关系,是充分利用我省热量资源,合理安排品种,适时采取栽培措施,促进水稻高产的一项必不可少的工作。 过去,研究水稻的生长发育与温度条件的关系,多采用“积温指标法”。由于积温指标的统计,是 Rice is a hi-temperature crop, its growth and development are closely related with the temperature. Studying the relationship between the change of rice development and temperature conditions is an indispensable task for making full use of the caloric resources of our province, arranging varieties rationally and adopting cultivation measures timely to promote high yield of rice. In the past, research on the relationship between the growth and development of rice and temperature conditions, more use of “temperature index method.” Due to the statistics of accumulated temperature index, yes
