在上海市气象局的主持下,我们参加了在郊区开展的后季稻安全齐穗气象工作方面的大协作,进行了多点试验,供试品种为沪选95、双丰1号、嘉农485、农红73,各品种在基本相同的肥水管理条件下,作了各生育期及抽穗扬花期的定穗、定粒观察试验,通过平行观测法(气象观测与作物农业观测一起进行),摸清上海各地气候差异对齐穗及扬花期空秕率的影响,并采取不同灌水方式和喷灌保温剂等措施,作减少空秕率的试验,现就两年的试验,作以下分析:
Under the auspices of the Shanghai Meteorological Bureau, we participated in large-scale cooperation in the safe and vigorous meteorological work of the latter part of paddy in the suburbs and carried out a number of experiments to test varieties for Shanghai 95, Shuangfeng No. 1, 485 and Farming Red 73. Under the same fertilizer and water management conditions, all varieties were given fixed-ear and fixed-grain observation experiments at different growth stages and heading and flowering stages. By means of parallel observation (together with meteorological observation and crop agriculture observation) To find out the effects of climatic differences across Shanghai on the percentage of spikelets and flowering stomata, and adopting different irrigation methods and sprinkler irrigation and thermal insulation agents to reduce the rate of air and plutonium, the following two years of experiments are as follows:
