不同栽培方法對溫室洋香瓜根溫及生育之影響

Abstract

現行溫室洋香瓜水耕栽培，不但能避免天然災害的發生，同時易於自動化管理，較土耕節省勞力，且突破連作的限制，更能調節栽培環境，而提高產量及品質。本試驗發現，利用銀黑色塑膠布包裹岩綿塊及栽培床於溫室秋作栽培，確能在日間提高根溫及養液溫度，並於夜間降低其溫度，與保麗龍栽培箱相差5〜7 °C，又可提高溫室洋香瓜之生長勢及著果率，爲一理想之栽培方式。 Current greenhouse muskmelon hydroponic culture has many advantages. It avoids natural disaters, favors automatic management, and reduces production cost. With proper adjustment, it can also break off succeeding crop limitation, modify culture environment, and improve yield and quality of muskmelon. By wrapping rockwool block and cultural bed with silver plastic film sheet and planted in autumn season, this experiment found that plants growth and fruit setting were better than those of polylon box culture. The method increased root and nutrient solution day temperature and decreased night temperature. Temperature difference between new method and polylon box culture was 5-7 °C. Results proved it to be an ideal muskmelon culture method.
