早熟温州蜜柑开花习性研究

The Investigation Flowering Habit of the Precocious Citrus unshiu

为了给早熟温州蜜柑（Citrus unshiu Marc．）栽培技术提供理论依据和制定科学管理措施提供参考．试验对早熟温州蜜柑的开花习性进行了调查研究。结果表明．早熟温州蜜柑早秋梢结果母枝群体中以结果母枝直径在2．1～9．0mm的百分率最大．占早秋梢结果母枝总数的87．7％．其中又以直径6．1～7．0mm的为最高，其百分率高达15．8％，其次是直径为5．1～6．0mm和7．1～8．0mm的，其百分率分别为14.3％和13．2％；早秋梢结果母枝粗细直接影响结果母枝上的总节位、萌芽节数量、萌芽率、混合芽花芽量、纯花芽花芽量、花芽总量、花果总量等农艺性状，以直径6．1～7．0mm的效果最好。其次是7．1～8．0mm和8．1～9．0mm的。春梢结果母枝粗细也影响早熟温州蜜柑结果母枝的总节位、萌芽节数量、萌芽率、混合芽花芽量、纯花芽花芽量、花芽总量、花果总量等农艺性状．春梢结果母枝粗的比细的好。结果母枝种类影响早熟温州蜜柑结果母枝的总节位、萌芽节数量、萌芽率、混合芽花芽量、纯花芽花芽量、花芽总量、花果总量等农艺性状，早秋梢结果母枝的效果显著优于春梢结果母枝。建议在早熟温州蜜柑的生产管理上．培养结果母枝首先要以早秋梢结果母枝为主，其次是培养春梢结果母枝：考虑结果母枝直径大小时．尽可能选择适宜直径的结果母枝，早秋梢以直径6．1～7．0mm的结果母枝为佳，其次是直径7．1～9．0mm的结果母枝：春梢以4．1～5．0mm的结果母枝为好．其次是直径3．1～4．0mm的结果母枝。

In order to provide theoretical basis for precocious Citrus unshiu Marc. cultivation techniques and provide reference for scientific management measures. Based on the investigation of the premature C. unshiu flowering habit. The results showed that, results in early autumn shoots female branch diameter size directly influence the outcome of different diameter size, the percentage of female branches result mother branch diameter and 2.1 to 9.0 mm accounted for 87.7%, and the diameter of 6.1 to 7.0mm as the highest, the percentage is as high as 15.8%, followed by a diameter of 5.1 to 6.0 mm and 7.1 to 8.0 mm, its high percentage of 14.3% and 13.2% respectively; Early autumn tip results mother branch diameter size directly affect the total section a, section germination, germination rate, bud type, quantity of flower bud, bud flower quantity and total amount of flowers, etc, the results to deal with the effect of the five best, second is the effect of treatment 6.1 to 7.0 mm Mother branch diameter. Spring tip results affect the precocious wenzhou mandarin result always a mother branches, germination, germination rate, amount of mixed bud bud, pure, mixed bud flower bud bud, bud total quantity, the total amount of pure bud flower, flower, the result shows that early spring of C. unshiu tip mother branches as thick as possible. The result mother branch type influence the outcome of a precocious C. unshiu mother branches, germination, germination rate, amount of mixed bud bud, pure, mixed bud flower bud bud, bud total quantity, the total amount of pure bud flower, flower, explain precocious C. unshiu early autumn tip results mother mother branches significantly better than the spring pin branch. On the production and management of premature C. unshiu, consider the parent branch type, advise first develop with early autumn female branch tip results was given priority to, the second was to develop the spring pin result mother branches; Considering the mother branches, mother branches for appropriate selection of the diameter of the result was good as far as possible, early autumn tip to the result of the 6.1 to 7.0 mm female branch is best, followed by the diameter of 7.1 to 8.0mmand 8.1 to9.0mm results mother branches; Spring pin to the result of the 4.1 to 5.0 mm female branch is best, second is the resuh of the diameter of 3.1 to 4.0 mm female branch.
