水培和琼脂培养试验的结果表明，缺Ｆｅ时，花生能有效地吸收利用Ｆｅ－Ｐ中的铁，与施用Ｃａ８－Ｐ相比，地上部吸铁增加３０．５８％，而在缺Ｐ条件下则没有这种趋势。在缺Ｐ条件下，花生能从Ｃａ８－Ｐ和Ｆｅ－Ｐ中吸收一定的磷，以Ｃａ８－Ｐ有效性稍高。而小麦在两种条件下均较好地利用Ｃａ８－Ｐ，在缺Ｆｅ条件下，两个小麦品种施Ｃａ８－Ｐ处理植株吸磷量分别增加了４３．６８％和７５．７４％；缺Ｐ时则分别增加４０．４８％和１１０．４９％，８１（８５）５－３－３－３品种比莱阳２６利用Ｃａ８－Ｐ的能力强得多。
The results of hydroponics and agar culture experiments showed that peanut can effectively absorb and utilize iron in Fe-P when compared with Ca-P, and the iron uptake in shoot increased by 30.58% in the absence of Fe, while in the absence of P Under this trend is not. In the absence of P, peanuts can absorb certain amounts of phosphorus from Ca8-P and Fe-P, with Ca8-P being slightly more effective. However, Ca8-P was better utilized in wheat under both conditions. In the absence of Fe, P uptake by two wheat cultivars increased by 43.68% and 75.74%, respectively. P deficiency (40.48% and 110.49% respectively). The 81 (85) 5-3-3-3 variety is much more capable of using Ca8-P than Laiyang 26.
