<正>沂水县目前栽植的黄桃主要有黄肉毛桃、黄肉毛蟠桃、黄肉油蟠桃等十余个品种,栽植面积3 333 hm2,其中以‘金皇后’为主的加工黄桃约1 333 hm2。普通鲜食黄桃在套袋情况下是黄皮黄肉的,不套袋是红皮黄肉的。‘黄桃920’套袋是黄皮黄肉的,不套袋也是黄皮黄肉的,但外皮略微有点黄绿色。沂水县发展的晚熟黄桃主要以‘新世纪’和‘黄金脆’为主,这两个品种都需要套袋管理,其中‘黄金脆’花粉量很少,需要人工授粉。 相似文献

SummaryThe effects of light, moderate, or heavy thinning (5, 10, or 20 cm between fruit, respectively), conducted before (7 d or 15 d), during, or after (7 d or 15 d) pit hardening (PH), on the incidence of split pits, fruit yield, fruit quality characteristics, and leaf mineral contents, were studied in the canning peach (Prunus persica L. Batsch.) cultivar ‘Andross’ over two growing seasons. The percentage of fruit with split pits increased by 58.2% in heavily-thinned trees compared with moderately- or lightly-thinned trees, and by 22.9% for the earliest time of thinning (15 d before PH) compared with thinning during, or after PH. Fruit fresh weight (FW) was greater in moderately- and heavily-thinned trees compared with lightly-thinned trees, but yields were similar among the different crop-load treatments. The latest time of thinning (15 d after PH) also had a negative impact on yield at first harvest and on total yield, fruit FW, and delayed fruit ripening compared to thinning during, and 15 d before PH. Total anti-oxidant capacities and phenolic contents were usually greater in fruit from heavily-thinned compared with lightly- or moderately-thinned trees only when thinning was conducted during, or 15 d after PH. Moreover, anti-oxidant levels were highest in fruit from the earliest-thinned trees. There was no significant effect of crop load, or of time of thinning application treatment on fruit colour, or on the K, P, Fe, Mn, and Cu contents of leaf tissues. In conclusion, light or moderate thinning during PH resulted in minimal split pits during processing, and in optimal yields and fruit quality characteristics in the canning peach cultivar ‘Andross’. 相似文献

酵素有机肥对京郊桃的产量品质与贮藏性的影响 总被引:5,自引:2,他引:3
以6 a生"久保"品种桃和4 a生"北京24号"品种桃为试材,比较了基施酵素有机肥,配合叶施和根灌酵素处理,基施农家肥,配合叶面喷肥处理及常规施肥3种处理对桃果实产量、品质和贮藏性的影响.结果表明:在3种施肥处理中,施用酵素有机肥的处理能够显著提高"久保"桃和"北京24号"桃果实产量,分别为8 250 kg/hm2和4 365 kg/hm2;可溶性固形物含量分别增加1.36%和1.92%,Vc含量分别降低0.64 mg/100g和0.68 mg/100 g,着色指数分别增加63.5%和67.7%;并且贮藏中烂果率降低13%. 相似文献
