覆膜对济渎红蒜产量及营养成分的影响

Effects of Film Mulching on Yield and Nutritional Components of Jidu Red Garlic

以济渎红蒜为试材,设覆黑膜、覆白膜、不覆膜3个处理,研究不同处理对大蒜营养生长、产量及营养成分的影响。试验结果表明,不覆膜利于济渎红蒜分瓣;覆膜可增加济渎红蒜株高、假茎粗以及叶片数,增加济渎红蒜鳞茎的横径、单头质量、单瓣质量及产量;白膜与黑膜相比,白膜更利于增加济渎红蒜植株的叶片数、大蒜鳞茎的纵径以及蛋白质含量;黑膜则更利于增加济渎红蒜的可溶性总糖及维生素C含量。

Taking Jidu red garlic as material, we studied the effects of different three treatments, black plastic film mulching, white plastic film mulching and no plastic film mulching on the vegetative growth, yield and nutritional components of garlic. The results showed that, the no plastic film mulching treatment had largest number of galic cloves, but the difference was not significant. Mulching plastic film could increase the plant height, stem diameter and leaf number of Jidu red garlic, and could increase the bulb diameter, single bulb weight, single clove weight and yield as well. Mulching white plastic film was more beneficial to increase the leaf number, longitudinal diameter of bulb, protein content of Jidu red garlic, while mulching black plastic film was more conducive to increase the total soluble sugar and vitamin C content of Jidu red garlic.
