摘要

本試驗以不同栽培季節行溫室洋香瓜對養液之消耗量調查，以做為養水分管理之調節基礎資料，其結果顯示：早春作、夏作、秋作、晚春作之每株每日之養液消耗量分別為1.56、1.71、1.02、1.43公升，以夏季最高。季節別每株之養液總消耗量分別為141.5、130、101、118.7公升，以早春作最高。溫室洋香瓜在各栽培季節的生育期間，依養分之消耗量可分為營養生長期、授粉小果期、果實肥大期和果實成熟期四個階段。而以果實肥大期之養液消耗量最大。該養液之消耗量與果實大小似有正相關。養液消耗量除季節別、生育階段之差異外，其他環境因素如氣溫、日照、風等環境因素亦有密切關係，本試驗各季節和生育階段之消耗量的調節與提高溫室洋香瓜品質之關係尚需行進一步試驗。

The purpose of present experiment was carried out to investigate the different growing seasons. The results indicated that the removal of nutrient solution at different cropping seasons of early spring, summer, autumn and late spring were 1.59, 1.71., 1.02 and 1.43 1/plant/day, respectively. While the total nutrient solution removed at different cropping seasons were 141.5, 130, 101 and 118.7 1 plant, respectively. The daily removal of nutrient solution per plant was higest in summer, and total removal was highest in early spring cropping season. Based on the removal of nutrient solution, the growth and development of greenhouse muskmelon can be divided into four stages, namely vegetative growth stage, pollinated young fruit stage, fruit enlargement stage and fruit mature stage. Maximum removal of nutrient solution was found in the fruit enlargement stage. This seems to be high correlation with fruit size. In addition to the growth stage and growing season, the removal of nutrient solution of greenhouse muskmelon might also be correlated with environmental factors such as temperature, light and wind.
