以2个果桑品种“无核大十”、‘46C019’为试材,通过避雨栽培和露地栽培对比试验,分析探讨了避雨栽培对2个供试果桑品种主要物候期与主要经济性状的影响。结果表明:避雨栽培使2个果桑品种物候期较露地栽培提前6~10d,具体提前时间因品种及其物候期不同而稍有差别。同时,避雨栽培方式下,2个果桑品种成熟果色泽没有变化,但平均单株产量、总糖含量均高于露地栽培,而成熟期落果性、病果率均低于露地栽培,但对总酸含量、出汁率影响不大。
Two fruit mulberry cultivars, “Seedless” and “46C019”, were used as materials to analyze the effects of shelter-cultivation on the main phenophase and The main economic traits. The results showed that the rain-shelter cultivation made the early growth of the two fruiting mulberry varieties 6 ~ 10 days earlier than that of the open-field cultivation. The specific advance time was slightly different due to the different varieties and their phenophase. At the same time, under the rain-shelving method, the color of ripe fruits of two mulberry cultivars did not change, but the average per plant yield and the total sugar content were higher than those of the open field cultivation. The total acid content, juice yield little effect.
