摘要： 以山东省德州市为试验地点,对用TL-Fe根系输液法矫正苹果缺铁黄叶病的效果进行了研究,结果表明:TL₁根系输液 6d后,苹果叶片全铁含量比ck增加104.16%,活性铁含量增加307.61%,14d后叶片全铁和活性铁达到最大值,分别比ck增加了147.35 %和 393.04 %,然后开始下降.TL₂ 处理 6d后,苹果叶片全铁和活性铁含量达到最大值,分别比ck增加273.22 %和 642.14 %,然后开始下降。TL1处理苹果叶片花全铁、活性铁、挂果数、座果率分别比ck增加140.79%,137.24%,230.35 %和 696.56%,但花朵数比ck减少25.18%。TL2 处理苹果叶片花全铁、活性铁、花朵数、挂果数、座果率分别比ck增加157.90%,189.16%,38.21%,214.82%和150.46%。从试验结果来看,两种浓度TL(TL₁,TL₂)根系输液对矫正苹果缺铁黄叶病均有较好的效果,均可持续一年的时间,但相比较而言,以TL1处理效果更好,也更经济

Abstract: This study was conducted to test the TL root soaking method on correcting iron deficient chlorosis in Chao soil in Dezhou city,Shandong province.The results showed that six days after TL₁ root soaking,the total iron and active iron of apple leaves were increased by 104.16% and 307.61%respectively,comparing with ck.Fourteen days later,the total iron and active iron were increased by 147.35% and 393.04% respectively and reached the peaks.The values then began to drop.Six days after TL₂ root soaking the total iron and active iron of apple leaves were increased by 273.22% and 642.14% respectively,comparing with ck.The parameters then began to fall After TL₁ application, the total iron and active iron of apple flowers were increased by 140.79% and 137.24% respectively, and the fruit quantity and fruit set percentage were increased by 230.35% and 696.56% respectively,yet the flower quantity was decreased by 25.18%.After TL₂ application, the total iron and active iron of apple flowers increased by 157.90% and 189.16% respectively, the flower quantity,fruit quantity and fruit set percent age were increased by 38.21%,214.82% and 150.46% respectively.The study indicated that both TL₁ and TL₂ applications had beneficial effects on correcting iron deficient chlorosis, yet TL₁ application was better and more profitable.
