摘要
葡萄是喜光植物,设施葡萄栽培中最难克服的是光照不足问题。除改进农膜透光性之外,通过合理的架式,改善设施葡萄的光照条件成为设施葡萄栽培中的重要技术措施。通过对改良式"V"形架不同叶幕层次、不同生育时期光照强度的测量和分析研究,以期探知最有利于葡萄生长发育的架式结构。试验结果表明,与直立篱架相比,改良式"V"形篱架能有效改善设施葡萄的光照条件,有利于设施葡萄的生长发育。
Grape is a light plant,light shortage is the most difficult problem to overcome in grape protected cultivation.In addition to improving light transmission of agricultural film,using a reasonable frame and improving light conditions is an important technical measure in grape protected cultivation.In this study,in order to get a rack structure of the most conducive to growth and development of grape,light intensity of different leaf screen levels and different growth stages of modified V-shaped frame were measured and analyzed.The results showed that,compared with upright frame,modified V-shaped frame can effectively improve light condition of facilities grape,and it is beneficial to the growth and development of facilities grape.
