摘　　要：研究了日光温室春茬栽培两个番茄品种中杂9号和百利对养分的吸收规律。结果表明:无论哪个生长阶段,除P2O5 外,百利对全N、K2O、Ca、Mg、Fe的吸收速率和需求量均明显高于中杂9号;对主要营养元素的吸收比例,品种间也存在差异,中杂9号对P、K的吸收比例相对较高,而百利对Ca、Mg的吸收比例较高。The experiment was conducted in solar greenhouse with tomato varieties Zhongza No.9 and Beril, in order to investigate the nutrient absorption characteristics in winter-spring. The results showed that, except P 2O 5, the uptake rate and amount of total N, K 2O, Ca, Mg, and Fe of Beril is obviously higher than that of Zhongza No.9. The uptake percentage of main elements is also different between varieties. Zhongza No.9 has a higher percentage of P 2O 5 and K 2O, but has a lower percentage of Ca and Mg.
