摘要: 为明确保水栽培方式与硼素两因素处理对甜菜叶片光合性能及产量品质的影响,探讨栽培方式和硼素对甜菜产质量影响规律,以期为甜菜抗旱高产高糖栽培提供理论依据。试验于2016年进行,通过不同栽培水分处理(CK、JG、FM、JF)和中后期叶片硼素施用(CK+B、JG+B、FM+B、JF+B)处理,对甜菜叶片SPAD值、产量以及品质进行了测定,并对SPAD值与产量品质的相关性进行了统计分析。结果表明,与对照相比JF保水处理能够显著提升产糖量;施硼能提升大田甜菜的含糖率、产量和产糖,JG+B提升含糖率和产量效果最佳,JF+B提高甜菜的产糖量效果最佳;施硼均提高甜菜叶片SPAD值,且SPAD值与甜菜含糖率存在最大的灰色关联度,两者具有紧密关系。综合分析得出,该生态条件下JF可作为抗旱节水的栽培模式,施硼增强了叶片光合能力、提高了产量和含糖,建议在生产中施硼与秸秆覆膜(JF+B)结合进行。

Abstract: The study aims to clarify the effects of soil moisture preserving methods and boron treatment on photosynthesis of sugarbeet leaves, and the yield and quality of sugrabeet, in order to provide a basis for cultivating drought-resistant, high-yield and high-sugar sugarbeet. The experiment was conducted in 2016. The SPAD value, yield and quality of sugarbeet were determined under different cultivating water treatments and foliar boron application in the middle and late stage. The correlation between SPAD values and the yield and quality was analyzed. The results showed that compared with the control, JF (the ridge mulched with plastic film and furrow cover the straw) water treatment significantly increased sugar yield, boron application improved the sugar content, yield and sugar production in field. For improving the sugar content and yield, JG+ B (the furrow cover the straw+ foliar boron application) had the best effect. JF+B had the best result for improving the yield of sugarbeet. The application of boron increased the SPAD value of sugarbeet leaves, and the SPAD value had the largest gray correlation degree with sugar content of sugarbeet, which had a close relationship. The comprehensive analysis shows that JF can be used as a cultivation model for droughtresistant and water- saving under the ecological condition. Boron application enhances leaf photosynthetic ability and increases yield and sugar content. It is suggested that boron application should be combined with straw mulching (JF+B) in production.
