水稻具有喜温好湿的生物学特性.为夺取水稻高产稳产必须创造一个最优的温湿环境,而水温则是影响水稻生长环境的重要因素之一.建国以来,我国修建了大量水库工程,大多是采用底孔放水建筑物,取水库深层低温水进行灌溉,影响水稻的生长和产量.若遇低温时期,则更加重对水稻的冷害.为引起对灌溉水温的重视,开展水库表层取水建筑物的研究,促进水稻的高产稳产,本期发表了四篇有关提高灌溉水温、水库表层取水建筑物等的文章,以供参考.
Rice has the biological characteristics of good temperature and good wet.In order to seize the rice with high and stable yield, it is necessary to create an optimal temperature and humidity environment, and the water temperature is one of the important factors that affect the growth environment of rice.After the founding of the PRC, a large number of reservoirs, Most of them use the bottom hole water diversion structures and take the deep water of the reservoirs for irrigation and affect the growth and yield of rice.In case of low temperature period, the chilling injury to rice is even more serious.In order to arouse the attention of irrigation water temperature, Studies of the matter, to promote high and stable yield of rice, this issue published four articles about raising irrigation water temperature, reservoir surface water intake structures, for reference.
