小麦籽粒的蛋白质含量与小麦抽穗到蜡熟期的日照时数的关系极为密切。经过多次反复试验研究证实 ,小麦要形成良好的品质 ,需要较强的太阳辐射。为了分析研究太阳光照对于小麦品质的影响程度 ,有人曾进行过如下试验 :采用人工降雨机对春小麦进行人工降水试验 ,白天因人工降水的 The relationship between the protein content of wheat grains and the hours of sunshine from the heading date to the ripening stage of wheat is very close. After repeated trial and error studies have confirmed that wheat to form a good quality, the need for strong solar radiation. In order to analyze and study the influence of sunlight on the quality of wheat, the following experiments have been carried out: artificial rainfall test on spring wheat for artificial precipitation, artificial precipitation during the day
