Vagetables Soilless Culture In Taiwan

Abstract

The earliest recorded scientific approach to soilless culture in Taiwan was in 1969 in the form of gravel culture. Commercial-oriented water culture researches started in 1984 with rockwool culture initiatied in 1988. The total acreage of soilless culture in Taiwan is estimated to be about 35 hectares in 1990. Among the 35 hectares, 20 hectares are water-cultured water convolvulus, leaf lettuce, pei-tsai, chinese kale and amaranthus etc.; 13 hectares are rice-hull-cultured pea sprout; 1.2 hectares rockwool carnation and 0.5 hectare gravel cultured daylily. Soilless culture systems used includes : water level regulating system and forced circulating system (deep water type); improved NFT system; root-floating system and rockwool culture. 台灣之無土栽培始於1969年。礫耕、水耕於1984年，岩綿耕於1988年開始有經濟生產。目前栽培面積估計約有35公頃。其中水耕約20公頃，以蘿菜、葉萵苣、白菜、芥藍、筒蒿、莧菜等為主，岩綿耕1.2公頃以番茄為主，礫耕0.5公頃以金針菜為主。另有13公頃的木屑或稻殼耕，以生產豌豆苗為主。 栽培方式可分為水位調節法、強制循環法、養液薄膜法、浮根法和岩綿法。
