摘　　要：为探究复合肥和铁元素肥料对四川苏铁生长繁育的影响,2022年在福建三明沙县区淘金山自然保护区和四川苏铁移植园建立试验区,以不施肥作为对照(CK),测定不同施肥量(0.10、0.25、0.50、0.75、1.00和1.25kg/株)下该植物新叶的叶长、叶宽和叶数;分析复合肥中添加95%硫酸亚铁肥对其叶片生长的影响。结果表明,不同复合肥用量的四川苏铁新生叶片生长状况存在差异,施用复合肥的新叶长度、宽度和数量均优于CK,以沟施0.50~0.75kg/株复合肥生长较佳;在施肥的过程中,添加0.10kg/株95%硫酸亚铁肥,可防止新叶出现缺铁性黄化症状。综上,施用复合肥的同时添加0.10kg/株95%硫酸亚铁肥有利于四川苏铁的生长繁育,改善其自然群落的生存环境,进而保护该植物的自然资源。本文为四川苏铁种群繁育提供参考。To explore the effects of compound fertilizers and iron element fertilizers on the growth and breeding of Cycas szechuanensis,experimental areas were established in Taojinshan Nature Conservation Community and Cycas szechuanensis transplant park in Shaxian District,Sanming City,Fujian Province in 2022,with no fertilization as control(CK).The leaf length,leaf width and leaf number of the plant were measured under different fertilization rates(0.10,0.25,0.50,0.75,1.00 and 1.25 kg/plant);the effects of adding 95%ferrous sulfate fertilizer to compound fertilizer on leaf growth were analyzed.The results showed that there were differences in the growth of new leaves of Cycas szechuanensis with different amounts of compound fertilizer.The length,width and number of new leaves applied compound fertilizer were better than CK,and the growth applied 0.50-0.75 kg/plant compound fertilizer was better.In the process of fertilization,adding 0.10 kg/plant 95%ferrous sulfate fertilizer can prevent the symptoms of iron deficiency yellowing in new leaves.In conclusion,applying compound fertilizer and adding 0.10 kg/plant 95%ferrous sulfate fertilizer was beneficial to the growth and breeding of Cycas szechuanensis,improve the living environment of its natural community,and protect the natural resources of the plant.This paper provides references for the population breeding of Cycas szechuanensis.
