摘要
本文通过测定不同种植方式的玉米群体基部光斑密度模拟出其相应的群体结构函数,同时通过实测的叶倾角与上述模拟函数最大值的叶倾角做了比较,两者相差不大。说明利用光斑密度,简化Ross方法是可行的。
In this paper the author measured facala density at the bottom of different planting way maize population, and simulated corresponding population structure functions. Comparimg actual leaf dip angle with that of simulated function, the maximum of both was close. It demonstrated that this method is a possible way to simple ROSS measuring method by measuring facala density.
