三峡库区水面种植研究

STUDY ON THE FEASIBILITY OF FLOATING CULTURE OF CROPS ON THE WATER SURFACE OF THE THREE GORGE RESERVOIR AREA

在自然水域中，采用聚氯乙烯泡沫板材以及竹框草绳、草垫浮体，对１３种作物进行水面种植。结果表明，水稻、藤菜、生菜、芋头及花卉作物朱顶红、兰花等的成活率高，达７０％以上，并获得较高产量。对试验中存在的问题进行了探讨，并为水面种植技术的继续研究提出了建议。

In 1995～1996, in the Three Gorge Reservoir area, floating culture experiments were made of 13 crops on natural water surface, supported by polyvinyl cloride plastic plates or straw blankets. Paddy rice, vine vegetable, lettuce, taro, vermei flower and orchid gave a survival rate of over 70% and a considerable yield. Some existing problems are discussed and a few proposals for further research in this respect are offered.
