牡丹盆栽基质热特性和热交换的初步研究

PRIMARY STUDY ON THERMAL EXCHANGE AND HEAT PROPERTIES OF SUBSTRATES FOR POT PEONY

本文对处于生育期的盆栽牡丹的四种基质,作了热特性和热交换的测定和计算。试验结果表明,选用的基质配方Ⅲ和Ⅳ,其导温率和热交换较大,且其开花率较高,而选用的基质配方Ⅰ和Ⅱ,其导温率和热交换较小,开花率较低。影响盆栽牡丹生长发育的因素极为复杂,本文仅从不同配比盆栽基质的热特性和热交换方面作了初步探讨。

Four different substrates were used to measure and calculate heat properties andthermal flux for pot peony during the growth and development. The results showed thatboth temperature conductivity and thermal exchange of substrates Ⅲ and Ⅳ were high andthose of substrates Ⅰ and Ⅱ were low. The flowering rate of peony plants cultured withsubstrates Ⅲ and IV was higher than that of peony plants cultured with substrates Ⅰ andⅡ. The factors influencing growth and development of pot peony were various. A primarydiscussion was made only about heat properties and thermal exchange of differentsubstrates.
