鼓粒期叶施烯效唑对绿豆各器官糖分积累及籽粒产量的影响

Effects of Foliar Spraying Uniconazole in Seed Filling Period on Sugar Accumulation in Various Organs and Grain Yield of Mung Bean

探讨鼓粒期叶施烯效唑对绿豆叶片、根系和茎杆糖分积累与光合特性及产量的影响,为绿豆高产栽培提供理论依据。在2013和2014年连续2年大田栽培条件下,以‘小明绿’为试验材料,鼓粒期叶施不同浓度烯效唑(15、30、60 mg/L),对照喷施等量清水,研究其对绿豆各器官糖分积累及产量的影响。研究结果表明:绿豆鼓粒期后,3种浓度烯效唑处理均呈不同程度提高了植株叶绿素、可溶性糖和蔗糖含量。与对照相比,烯效唑处理下绿豆糖分含量增加显著,且生育后期仍能维持相对较高的糖分积累。可得出结论:鼓粒期叶面喷施烯效唑可调控绿豆植株不同器官光合特性与糖分积累,最终提高籽粒产量。

In order to provide theoretical foundation for high-yield cultivation, the effects of foliar sprayinguniconazole of different concentrations（15, 30 and 60 mg/L） in seed filling period on sugar accumulation ofleaves, root and stem, photosynthetic characteristics and yield were discussed. Field tests were conducted in2013 and 2014, the effects of uniconazole of different concentrations（water was used as CK） on sugaraccumulation and yield of‘xiaominglv＇were analyzed. The results showed that those three concentrations ofuniconazole could improve chlorophyll, soluble sugar and sucrose contents of plant in different degrees afterseed filling period. Compared with CK, uniconazole could increase sugar content of mung bean and keep a highsugar content level in the late growth period. Foliar spraying of uniconazole could regulate and control photosynthetic traits of different organs and sugar accumulation of mung bean, which could increase the yieldat last.
