阶段性避雨及基肥施用时期对毛葡萄产量及品质的影响

Effect of Periodical Rain-shelter-cultivation and Application Stages of Base Fertilizer on the Yield and Quality of Vitis quinquangularis Rehd

为探讨阶段性避雨及基肥施用时期对毛葡萄两性花新品种野酿2号产量和品质的影响,进行了覆盖薄膜及不同时期基肥施用试验。结果表明:在毛葡萄生育期间采用阶段性避雨栽培对产量增加和品质提升均有明显的效果,产量和可溶性固形物含量分别比对照增加107.4%、5.8%。在采取阶段性避雨栽培模式下,分别在采后、落叶初、萌芽前三个不同时期施用基肥也对毛葡萄产量和品质有较大影响,以阶段性避雨采收后即施用基肥对野酿2号产量的影响最为明显,产量为22 211.1kg·hm-2,比阶段性避雨萌芽前施基肥增产57.4%;该处理对毛葡萄野酿2号品质的影响最为显著,其可溶性固形物含量为11.6%,比阶段性避雨萌芽前施基肥增加6.4%。阶段性避雨采收后即施用基肥处理是野酿2号较优基肥施用时期,可在生产上推广应用。

In order to study the effects of periodical rain-shelter-cultivation and application stages of base fertilizer on the yield and quality of Vitis quinquangularis Rehd.,the mulching films and different period of fertilizer test.The results showed that periodical rain-shelter-cultivation had obvious effect on yield increase and quality upgrading.Yield and soluble solids content increased by 107.4%,5.8%than that of CK,respectively.In taking periodical rain-shelter-cultivation modes,respectively in the early postharvest,deciduous,germination of three different periods fertilizer also had greater impact on the yield and quality of Vitis quinquangularis Rehd.That effect of fertilizer post harvest on the yield was the most obvious,the yield was 22 211.1kg·hm-2,compared with CK（fertilized before sprout）yield 57.4%;The effect of the treatment on quality was also the most significant.The content of soluble solid was 11.6%,an increase of 6.4% compared with CK（fertilized before sprout）.This test was a better application stage of base fertilizer,which could be applied in production.
