摘要
以两系法杂交稻两优培九在南京和镇江两地的分期播种资料为基础 ,选出与产量密切相关的 5个高产关键期 ,用回归统计分析方法组建气象响应模型 ,得出各高产关键期的最适气象条件值。以此为依据 ,用 1 95 1～ 1 992年江苏省赣榆、徐州、高邮、南京、常州、溧阳、苏州等 7个地区的气象资料 ,在高产关键期预测的基础上 ,计算了 4种茬口各产量构成因素的气候值并与最适气候值进行比较 。
In terms of data on staging sowing experiments with two line hybrid rice Liangyou Peijiu in Nanjing and Zhenjiang,five critical stages in which high yield could be achieved were chosen.Using regression analysis,models were established and optimal meteorological condition for each stage was obtained.Furthermore,by dint of meteorological data from Ganyu,Xuzhou,Gaoyou,Nanjing,Changzhou,Liyang and Suzhou of Jiangsu Province separately,yield built climate elements were estimated and compared with optimal ones for four crop rotations respectively and recommendations for high rice yield were presented in view of agrometeorological technique.
