摘要
在同一区域内,对某一水稻亲本材料进行多点观察,应用皮尔生长曲线对叶片生长动态进行拟合,建立水稻展开叶生长模型。依据模型计算出水稻父(母)本的生长日数、两生育时期的期距,以此预测水稻花期,确定相应的技术措施。
Based on the performances of some parental materials of rice observed at multi-site of the same region, the growth model of rice expanding leaves was established by drafting the leaf growth dynamic with Peal growth curve. According to the growth dates and gap of the two parental lines to predict the flowering stage and take appropriate technical approaches by use of the model is possible.
