田间喷施和埋瓶吸收尿素铁试验表明,能增加叶片和果实活性铁和全铁含量,使叶绿素含量大幅度提高,增加结果数,提高大果率和单果重,改善果实品质和果实均匀度。从单株产量看,喷施1.0％浓度的尿素铁效果较好。埋瓶吸收增产幅度达50％以上。~(59)Fe示踪试验证明,铁肥不同施用方法~(59)Fe的吸收率埋瓶>涂叶>土壤施入。埋瓶与土壤施入相比,埋瓶吸收的~(59)Fe往叶片运转的数量较土壤施入高得多。配合施肥的结果表明,高量钾肥影响~(59)Fe的吸收,而牛粪则有利~(59)Fe的吸收。磷肥、牛粪和醋酸均能促进铁素向叶部运转,其中醋酸效果尤为明显。
Field spraying and buried flask absorption of urea iron test showed that the activity of iron and iron can increase the leaves and fruits, so that significantly increased chlorophyll content, increase the number of results, increase the rate of large fruit and fruit weight to improve fruit quality and fruit uniformity . From the yield per plant, spraying urea concentration of 1.0% better. Buried bottle absorption rate of increase of more than 50%. ~ (59) Fe tracer test showed that the application rates of iron fertilizer ~ (59) Fe were buried in bottles> painted leaves> soil. Compared with the soil application, the amount of ~ (59) Fe adsorbed by the buried flask was much higher than that of the soil application. The results of fertilization showed that high K fertilization affected the absorption of ~ (59) Fe, while that of cow dung was beneficial to the absorption of ~ (59) Fe. Phosphate, cow dung and acetic acid can promote the operation of ferrite to the leaves, especially acetic acid effect is obvious.
