摘　　要：以中杂9号番茄为试材,研究了秋冬、冬春两个茬口日光温室内不同光温环境下番茄对锌的吸收和分配规律。结果表明:秋冬茬番茄对锌的吸收量仅为冬春茬的76．98％。不同茬口不同生育阶段植株吸收锌的量不同,秋冬茬和冬春茬番茄对全锌的吸收量均呈单峰曲线,生育前期吸收量所占的比例小,果实膨大期和采收初期吸收量所占比例大,冬春茬为63．07％,秋冬茬约为68。36％。Tomato cultivar Zhongza No. 9 was planted as experimental material to investigated zinc uptake and distribution under different inner light and temperature conditions during winter-spring and autumn-winter crops. Results indicated that zinc uptake amount was 76.98 % of that in winter-spring crop; the content of uptake to zinc was a single peak curve,and the proportion is larger in fruit formation and early picking stage,which were about 63.07 % and 68.36 % respectively in winter-spring and autumn-winter crops.
