滴灌对温室新几内亚凤仙生长的影响

Effects of Trickle Irrigation on the Growth of Impatiens New Guinea(Impatiens hawkerii) in Greenhouse

本文利用正交试验方法,研究了滴灌灌水量和灌水周期对温室新几内亚凤仙生长的影响,初步得出了温室中新几内亚凤仙生长的最佳灌水量和灌水周期.试验表明,灌水量和灌水周期以及它们的交互作用对新几内亚凤仙生长的影响主次和程度,因新几内亚凤仙生长阶段的不同而不同,因此灌水量和灌水周期应根据生长阶段和生产实际情况的不同分别确定.

The orthogonal design was used in a trickle irrigation experiment to study the effects of irrigation rate and periodicity on the growth of impatiens New Guinea （Impatiens hawkerii） in a greenhouse. The optimum irrigation rate and periodicity were tentatively established. The results showed that effects of irrigation rate and periodicity and their interactions on the growth of I. hawkerii varied with the growth stages of the plant. Therefore, we should refer to the different growth stages and actual production conditions in determining irrigation rate and periodicity for the plant.
