適用於果菜類作物栽培之溫室

Abstract

溫室披覆材料的光線穿透性是影響作物生長及發育的重要因子，本文收集多篇相關文獻，探討不同披覆材料對溫室內光質及光強的影響。此外，台灣夏天溫室降溫為重要的課題，在自然通氣無法將過多能量帶走前提下，披覆材料塗成白色或溫室遮蔭也是可考慮的降溫策略。此外，紫外光可誘導合成類黃酮，該物質是作物花色素的重要成分；因此，溫室栽種花卉作物應避免使用過濾紫外光的披覆材料。增加溫室內二氧化碳濃度有助於作物生長，但實際運用時，需考慮作物反應效率及設備使用方法，例如成本、氣候及二氧化碳之分布等。 Light transmitted by greenhouse cladding or shading materials is essential to influence on the growth and development of plants. This review article collected abundant literature to evaluate the light quality and quantity within greenhouse with different photoselective plastic films. In addition to, greenhouse cooling is an important matter during sunny summer days of Taiwan. Natural ventilation is the normal practice, however, it is not sufficient for extracting the excess energy. Therefore, whitening the cover material or shading the greenhouse may be considered as the strategy of cooling. UV light induces the synthesis of flavonoids which are the important component of flower pigments for plant, therefore, the UV-cut plastic sheet should be avoid when cultivated flower crops in greenhouse. Many greenhouse crops respond favorably to CO2 enrichment, however, the constraints was found in crop response efficiency and method of implementation, such as cost, climate and CO2 distribution.
