A Computer Program for Automatic Watering Based on Potential Evapotranspiration by Penman Method and Predicted Leaf Area in Miniature Pot Rose Production

In this study, we developed a computer program for automatic prediction of watering time point by considering the environmental factors such as solar radiation, air temperature and relative humidity based on the multiple linear regression equation of leaf area and Penman Method. The experiments were carried out for a year in two watering experimental plots, one of which was controlled by pF value, and the other by the computer program. After comparing the results of the two plots, the following findings were obtained. In the computer program plot, the observed and predicted values of both leaf area and evapotranspiration indicated significant correlation at the 1% level, which suggested that the computer program had high prediction accuracy. In addition, no significant difference was observed between the two experimental plots with respects to the plant height, plant diameter, leaf area, leaf number, fresh weight, and dry weight, which demonstrated that the plants in the computer program plot had normal growth. On the other hand, although the number of flower buds and flowering shoots showed higher values at the end of certain cultivations in the computer program plot than those in pF value plot, we proposed that it was due to the effect of cumulative daily solar radiation in the greenhouse, rather than the watering. Thus, we have reached the conclusion that the computer program for automatic prediction of watering time point developed by this study has high applicability in miniature pot rose production.     

田间与盆栽2种模式对皂荚光合特性的影响

为进一步探讨盆栽模式对树木幼苗光合的影响,以皂荚幼苗为材料,对田间与盆栽2种栽培模式下光合和荧光参数日变化展开了研究。光合日进程研究表明:盆栽皂荚Pn最大值出现在6:00,为5.8μmol/(m2.s),此时Pn、Tr和WUE高于田间,而Rs和Ci低于田间;而田间皂荚Pn最大值出现在10:00,为10.6μmol/(m2.s),此时Pn、Tr和WUE高于盆栽,而Rs和Ci低于盆栽。叶绿素a荧光日进程研究表明:盆栽皂荚Fo、Fm、Fv和Fv/Fm在午前没有降低;而16:00以后,除Fo外,Fm、Fv和Fv/Fm均明显降低,分别降低了23.1%~24.4%、23.1%~36.9%和16.6%~23.1%。说明盆栽模式改变了皂荚光合各参数日变化模式,而且午后盆内供水不足使皂荚叶片光合器官受到伤害。
