2010—2013年连续3年,分别采用≤7.2℃模型、0~7.2℃模型和犹他模型,对适宜设施栽培的6个枣品种的需冷量及相关特性进行研究。结果表明,同一枣品种在不同模型下的需冷量差异较大,不同品种间需冷量差异明显,6个枣品种在3种模型下的需冷量均依次为马牙枣<早脆王<沙窝枣、马铃脆枣<红螺脆枣<冬枣。枣品种果实成熟期与需冷量存在一定的关系,需冷量低的品种解除休眠早,物候期亦早,果实成熟期也早,反之则晚。建议天津地区设施栽培马牙枣于12月上旬扣棚,早脆王12月中旬扣棚,沙窝枣、马铃脆枣12月中下旬扣棚,红螺脆枣12月下旬扣棚,冬枣1月上旬扣棚。 2010-2013 for three consecutive years, respectively, ≤ 7.2 ℃ model, 0 ~ 7.2 ℃ model and Utah model, suitable for the cultivation of 6 jujube varieties of cold storage capacity and related characteristics were studied. The results showed that the same jujube varieties in different models of the greater demand for cooling capacity, different varieties of cold required significant differences in the 6 jujube varieties in the three models were followed by the cooling needs of the early teeth crisp
