绿肥压青对芒果产量和品质的影响

目的]为三亚地区芒果高产优质栽培提供依据。方法]设计飞机草、大豆、紫云英3个绿肥压青处理,以休闲作对照,研究绿肥压青对芒果产量和品质的影响。结果]飞机草处理的芒果单果重、单株结果数和单株产量最高,其中单株产量分别比大豆、紫云英处理和对照增加0.4%、0.6%和14.0%。大豆处理的芒果可溶性固形物含量最高,为14.4%。绿肥压青处理的芒果Vc含量高于对照。飞机草处理的芒果总糖含量最高,为14.11%。对照的芒果总酸度、粗纤维含量均最高,分别为0.49%、0.62%。绿肥压青处理的芒果树叶片的N、K含量均高于对照。结论]绿肥压青能提高芒果产量,增加芒果Vc含量和总糖含量,提高芒果品质。

Influence of Green Manure Dressing on Yield and Quality of Mango

Objective] The aim was to provide the basis for high yield and quality cultivation of mango in Sanya area. Method] With fallow as the control , 3 treatments with green manures of Chromolaena odoratum, Glycine max and Astragalus sinicus were designed to study the influence of green manure dressing on yield and quality of mango. Result] The single fruit weight, fruit number per plant and yield per plant of mango treated with C. odoratwn was highest and its yield per plant increased by 0.4%, 0.6% and 14.0% than that treated with G. max, A. sinicus and control, resp. The soluble solid content of mango treated with G. max was highest, being 14.4% . The vitamin C content of mango treated with green manure dressing was higher than that of the control. The total sugar content of mango treated with C. odoratum was highest, being 14.11%. The total acidity content and crude fiber content of the control were all highest, being 0.49% and 0.62% , resp. The N and K content in the leaf of mango treated with green manure dressing were all higher than that in control. Conclusion]Green manure dressing could enhance the mango yield, increase the vitamin C content and total sugar content of mango and improve the quality of mango.
