摘  要：
为了降低新栽皇冠梨越冬期间抽条率和提高萌芽后枝条生长量,研究了树干不同保护措施土袋保湿、石灰涂白、薄膜包裹和草绳缠绕对树温、树干含水量、电导率、发芽率、抽枝率和萌发后新枝生长量的影响。结果表明:土袋保湿措施的13:00树温、树干相对电导率和抽枝率相对最低分别为5.6℃、42.1%和8.6%,较对照CK分别降低了56.4%、40.0%和71.7%;土袋保湿措施的树干相对含水量、树干顶部81~120cm处的发芽率、新枝长度和粗度分别为42.5%、85.6%、72.3cm和35.5mm,较对照CK分别提高了65.4%、64.6%、121.8%和179.5%。土袋保湿措施的所有测定指标与对照CK相比,均达到了显著水平(P<0.05)。鉴于土袋保湿措施的相对最佳效果,建议在皇冠梨越冬期间可采用这一措施来保护树体。

摘  要：
The effects of different protecting measures in soil bag,lime,film and rope on the water content,conductivity,germination rate,dry rate and shoot growth were studied for decrease dry rate in winter and increase shoot growth of Pyrus bretschnelder Rehd after germination.The result showed that the branch temperature in 13:00,relative conductivity,dry rate of protecting measure in soil bag were 5.6℃,42.1%and 8.6%respectively,decreased 56.4%,40.0%and 71.7%compare to CK;the branch relative water content,germination rate in 81~120cm,shoot length and diameter were 42.5%,85.6%,72.3cm and 35.5mm respectively,increased 65.4%,64.6%,121.8%and 179.5%compare to CK.All index of protecting measure in soil bag were significant(P<0.05).Protecting measure in soil bag was suggested to protect Pyrus bretschnelder Rehd branches in winter for its best effect.
