摘要
以香蕉和粉蕉为试验材料,研究施用肥料增效剂的效果。结果表明:施用肥料增效剂能极显著增加蕉果产量,增产量为7 85t/hm2~22 15t/hm2,相对增产19 6%~57 8%,收益增加7704元/hm2~23150元/hm2,每公斤肥料增效剂增值8 87元~14 82元。肥料增效剂的适宜用量为1500kg/hm2,施用肥料增效剂能加快出叶速度,提早现蕾28~60天,增强蕉株抗寒力,明显增加蕉叶N、P2O5、K2O、MgO、S、Zn和B的养分含量。
Studies on the effect of the FS applied on bananas (Musaceae AAA, ABB) showed that the FS could extreme significantly increase the yield of fruits by 785t/hm2~2315t/hm2(196%~578%), and the net income were increased by RMB 7704yuan/hm2~23150yuan/hm2, The efficiency per Kg FS were 687yuan~1482yuan The adequate doses of FS were 1500kg/hm2 The application of FS could Promote the speed of leaf emerging, made the flower bud developed 28-60d earlier than no FS, strengthen the coldness tolerance and significantly increase the contents of N, P2O5, K2O, MgO, S, B and Zn of Leaves
