採用小型PE隧道棚模式栽培洋香瓜較畦面敷蓋稻草,畦面敷蓋稻草+玉米植株暨畦面敷蓋銀黑色塑膠布+玉米植株之栽培模式,其平均最高溫度增加9℃(大型PE隧道棚僅增4.4℃),平均最低溫度增加2℃,平均地溫則增加2.3℃;植後50日之瓜蔓生長勢,小型及大型PE隧道棚栽培模式分別增長59.9%及51.7%;從73年12月上旬種植迄瓜果採收所需日數,小型PE隧道棚平均為119.5日,較大型PE隧道棚,畦面敷蓋稻草,畦面敷蓋稻草+玉米植株及畦面敷蓋塑膠布+玉米植株之栽培模式分別提早1.5日,10.7日,13.7日及10.9日,採收始期則提前4日,16日,26日及18日。大型PE隧道棚栽培模式之單粒果重最重,比小型PE隧道棚,畦面敷蓋塑膠在+玉米植株,畦面敷蓋稻草+玉米植株與畦面敷蓋稻草等栽培模式比較分別增產4.7%,26.7%,37.8%及50.2%;小型或大型PE隧道棚栽培模式之果實糖度較其他三種處理高1.4∼2.2度。小型PE隧道棚栽培模式裂果率最低僅1.5%,較大型PE隧道棚,畦面敷蓋塑膠布+玉米植株,畦面敷蓋稻草+玉米植株及畦面敷蓋稻草等栽培模式分別減少3.7%,8.9%,16.7%及18.9%。

Effect of the Different Cultivation Systems on the Growth Yield and Quality of Muskmelon

S. R. Yang

Summary

An experiment was carried out in the soil texture of sandy-loam at An-Nan, Tainan City to study the effect of the different cultivating system on the growth, maturity, productivity and quality of muskmelon. cv. No. 8 Tainan. The cultivating systems were adopted as follows: (a) Plots mulched with rice straw; (b) Plots mulched with rice straw and planted corns as windbreak; (c) Plots mulched with black polyethylene film and planted corns as windbreak; (d) Plots covered with 0.15 mm thick transparent polyethylene plastic tunnel (0.8m high); (e) Plots covered with 0.15 mm thick transparent polyethylene plastic tunnel (2.5m high). The results showed that the mean min.-max. temperatures were 2~9℃ and 1.6~4.4℃higher, respectively in (d) and (e) than other systems. The growth rate was highest in (d), followed by (e) and lowest in (b). The days from planting to harvesting were 9.2~13.9 days earlier (16~26 days earlier in 1st harvesting date) in plastic tunnels then other systems. The highest yield, produced by (e), were 4.7, 26.7, 37.8 and 50.2% higher, respectively than those obtained by (d), (c), (b) and (a). The sugar content were greatest (14.1 & 14 oBrix, respectively) in (e) and (d), followed by (a) and (c) and lowest by (b). The least percentage of fruit cracking (1.5%), obtained by (d), were 3.7, 8.9, 16.9 and 18.9% less, respectively than those obtained by (e), (c), (b) and (a).
