为了研究玉米整个生育期有效积温以及钾肥使用量与茎粗的关系,通过设置不同钾肥水平处理的田间试验,定期定株测量甜玉米茎粗数据,以及同步记录相关气象数据,并利用CurveExpert软件进行拟合.结果表明, Richards模型和高斯模型拟合结果最好,相关系数分别为0.995和0.996.该结果可以有效地估测各个生育期甜玉米茎粗的变化,可为甜玉米生产管理提供数据支持.
為瞭研究玉米整箇生育期有效積溫以及鉀肥使用量與莖粗的關繫,通過設置不同鉀肥水平處理的田間試驗,定期定株測量甜玉米莖粗數據,以及同步記錄相關氣象數據,併利用CurveExpert軟件進行擬閤.結果錶明, Richards模型和高斯模型擬閤結果最好,相關繫數分彆為0.995和0.996.該結果可以有效地估測各箇生育期甜玉米莖粗的變化,可為甜玉米生產管理提供數據支持.

In order to study the relationship among the effective accumulated temperature , stem diameter and the K rate , different K treatments were set , the data of stem diameter and weather regime were taken notes regularly , and the data were analyzed by Curve Expert software .The results showed that the Rich-ards model and Gauss model were fitting best , the correlation coefficients were 0.995 and 0.996 , respec-tively.The results could be effectively used to estimate the changes of stem diameter in every period of sweet corn growth , and provided the data support in production management .
