我国热带海岛地区极端环境下蔬菜椰糠基质栽培系统的建立

研究并建立了适合我国热带海岛地区高温、高湿、强光照、多台风、缺水、缺土等极端条件下蔬菜椰糠基质栽培系统,包括以抗强台风、防日晒、防暴雨、防腐蚀的四防温室为主的环境调控系统、以椰糠为主要栽培基质的栽植系统和肥水供给系统。在建立的椰糠基质栽培系统下,抗强台风、防日晒、防暴雨效果明显,而温度和湿度调控效果不佳。较岛上人造菜地,适宜栽培蔬菜种类和产量明显增加,节水率达到70%以上。

Establishment of Vegetable Coconut Coir Cultivation System under Extreme Environment in Torrid Islands Region of China

We studied and established a vegetable coconut coir cultivation system fit for torrid island regions of our country under extreme environment, such as high temperature, high humidity, strong illumination, varied typhoon, water and soil shortage, etc. The whole system consists of three subsystems: environment control system mainly including anti-typhoon, anti-solarization, anti-rainstorm and anti-corrosion greenhouse, fertilizer and water supplying system and coconut coir planting system. It has an obvious effect on anti-typhoon, anti-solarization and anti-rainstorm, but a poor performance on controlling of temperature and humidity. Comparing to vegetable plot in these islands, suitable cultivated vegetable species and their yields are significantly increased. The water saving rate has reached over 70 %.
