在石灰性土壤上以磷矿粉和天然沸石为试材进行盆栽试验,结果表明,在石灰性土壤上沸石对磷矿粉具有较强的活化作用,能使土壤速磷增加14.1%~50.5%,植物磷素增加5.0%~21.7%,大豆产量增加9.8%~20.7%,另外,沸石的施用量也并非越多越好,在本试验中,沸石以每盒施12.5g的效果最好。
In calcareous soil, phosphate rock and natural zeolite were used as potting materials. The results showed that zeolite had a strong activation on phosphate rock in calcareous soil, which could increase the soil phosphorus up to 14.1% 50.5%, Phosphorus increased by 5.0% ~ 21.7% and soybean yield increased by 9.8% ~ 20.7%. In addition, the application rate of zeolite is not as good as possible. In this experiment, Zeolite 12.5g per box is best.
