光生态膜的荧光光谱对番茄生态的影响

The Reformation of Tomato Ecology Using Photo-ecology Film

通过番茄叶片的荧光光谱和激发光谱测量 ,能够得到番茄的光合作用之作用光谱。模拟番茄的作用光谱制备出荧光助剂 ,将荧光助剂分散进高分子树脂中制成棚膜。用这种光生态膜苫盖日光温室 ,在哈尔滨市道里区新发乡建国村进行了温室番茄种植的示范推广 ,番茄产量提高了 5 3 7% ,产值提高了 6 1 4 %。

The action spectrum of photosynthesis of tomato was studied with excitation and fluorescence spectra of its leaf. To simulate action spectrum of tomato the fluorescent auxiliary was specially prepared and used to make the photo-ecology film. The film was used to cover the roof of greenhouses for planting tomatoes in Jianguo village of Xinfa town, Daoli district, Harbin. The survey of ecology conditions, tomato growth and yield has been made in comparison with those in the greenhouse using normal film. It is shown that the yield of tomato in the photo-ecology film greenhouse has increased by 53.7%, which leads to a production value rise of 61.4%.
