洋香瓜產期調節之試驗研究

Abstract

以色列生產之Netafilm 滴水灌溉系統，其出水量較為穩定，滴管長度由 0-100公尺之間，每一滴嘴出水量皆能維持本均每分鐘為20cc。養液滴灌區本均單株結果數為3.2個，果重為1.26公斤，果長15.1公分，果寬12.5公分，糖度 12.6 Brix均較對照區(不滴灌)單株結果數2.8個，果重1.05公斤，果長14.4公分，果寬12.0公分，糖度9.6 Brix 為佳。初步結果得知日本山崎洋香瓜養液配方亦適於洋香瓜露地滴灌栽培。 Netafilm drip irrigation system made by Israel had a morestable water exuding capacity. It was found that water exuding capacity for each drizzle maintained persistently 20 cc/minin a irrigation tube within 0-100 meter. Muskmelon cultivated in the field by means of nutrient drip irrigation indicated that the mumber of fruit per plant (3.2 fruit/plant), fruit weight (1.26 Kg/fruit), fruit length (15.1 cm), fruit width (12.5 cm) and sugar content (12.6 Brix) were much better than control one. In case of control treatment, it was 2.8 fruit/plant, 1.05 Kg/fruit, 19.4 cm fruit length, 12.0 cm fruit width and 9.6 Brix to be observed, This result showed that Yamasaki's muskmelon nutrient formula was also favoured for use in muskmelon outdoor culture irrigation.
