溫網室栽培衍生之土壤鹽化改良技術

Abstract

台灣的設施蔬菜生產對台灣調節惡劣氣候的菜價有大貢獻，然而設施栽培常面臨高鹽分累積限制其蔬菜栽培。田菁的品系相當多台灣以往主要注重在其為重要綠肥作物。然而越來越多國家採用田菁做鹽分地改良及鹽分地利用的重要植物，因此，本研究其利用田菁作為溫網室鹽分去除作物且可做為綠肥，希望一舉兩得。

The housing vegetable in Taiwan is a very important gorwing system to ease the pressure of high vegetable price during serious weather, especially the heavy rain which comes more often in recent years. However the accumulation of salt in housing plantation system is a serious problem in liminting the growth of most vegetables. Sesbania scop. has about 70 species, and there are wild type in Taiwan. The planting of sesbania is usauaaly focused on their nitrogen fixing potential and species are known as good green manures. Nowadays some countries already have noticed on their potential in desalination of salt affected soils. This study will introduce the sesbania in housing vegetable growing system for removing the extra salt and supplying as organic fertilizer as well.
