摘    要:
为获得准确可行的判断植株快速生长期的方法,在确定了几种花卉营养条件的调控以植株生长状况为主要参考标准的前提下,通过建立无土栽培条件下的生长动力学方程,得到了形如Logistic方程的结果,并以此进行了讨论,为无土栽培中确定植物的需肥高峰及持续时间、高效科学的肥水管理措施以及培养条件的优化提供了参考依据。

关 键 词:无土栽培 回归 生长动力方程 Logistic

Abstract:
To obtain an accurate and feasible method to determine the rapid growing period of several ornamental plants, a kinetic equation similar to the Logistic equation was established. The equation is based on a relationship between the nutrition and growth conditions of these plants under soilless (cultivation). A discussion on the equation is presented. By these results, the peak period of the (fertilizer) demand of the plants and the lasting time of the fertilizer can be found, thus providing a basis for (determining) the optimum cultivation process in practical production.
Keywords:soilless cultivation  regression  growth kinetic equation  Logistic.
