以‘金煌1号’杧果为试材,研究双层搭架矮化避雨栽培对其物候期与果实形质、产量的影响。结果表明:与露地栽培相比,矮化避雨栽培可使‘金煌1号’杧果盛花期推迟2~3 d,末花期及果实转色期推迟3~4 d,果实成熟期推迟5~6 d;特级果比率提高17.22%,发病率、裂果率分别降低7.41、1.84百分点,商品果率、优质果率分别提高12.96、10.5百分点;平均单果重提高18.01%,可溶性固形物含量提高1.2百分点;树冠高度降低33.77%,两性花坐果率提高49.04%,株产、667 m~2产量分别提高29.21%、24.63%。
Taking ’Jinhuang No.1’ as experimental material, the effects of double-shelled dwarf shelter-rain cultivation on its phenology, fruit shape and yield were studied. The results showed that compared with the open field cultivation, dwarf rain-sheltering cultivation could delay the flowering period of ’Jinhuang 1’ from 2 to 3 days, the post-flowering stage and the fruit color-changing period postponed for 3 to 4 days, and the fruit ripening stage postponed 5 ~ 6 d, the rate of special grade fruit increased by 17.22%, the incidence rate and split fruit rate decreased by 7.41 and 1.84 percentage points respectively, the average fruit weight increased by 12.96 and 10.5 percentage points respectively; the average fruit weight increased by 18.01% and the soluble solid content increased by 1.2 Percentage points; crown height decreased by 33.77%, breeder fruit rate increased 49.04%, plant yield, 667 m ~ 2 output increased by 29.21%, 24.63%.
