摘要
[目的]探究铁、镁、锌肥配施对兰州百合根系活力及产量质量的影响,以期为兰州百合绿色高产栽培技术提供科学依据.[方法]采用"3414"正交试验设计方案,测定铁、镁、锌肥配施对兰州百合根系活力及产量质量.[结果]铁肥5 kg/hm2的600倍液+镁肥5 kg/hm2的800倍液+锌肥5 kg/hm2的800倍液混合喷施对兰州百合根系活力及产量质量影响最佳,鲜、干产量分别为 5 864.8 kg/hm2、1 646.7 kg/hm2,分别较对照增加 1 238.5、535.3 kg/hm2;根系活力为127.55 μg/(g·h),较对照增加68.68 μg/(g·h);鼠李糖、木糖、果糖、葡萄糖、蔗糖、浸出物含量分别为 1.069%、1.182%、2.757%、4.519%、11.151%、44.70%,分别较对照增加 15.06%、74.67%、144.21%、44.50%、84.00%、45.78%.[结论]铁肥 5 kg/hm2 的 600 倍液+镁肥 5 kg/hm2 的 800 倍液+锌肥5 kg/hm2的800倍液混合喷施效果最佳,两两配施对其根系活力及产量质量促进作用由高到低依次铁镁>镁锌>铁锌,单素施肥对其根系活力及产量质量促进作用由高到低依次为锌>铁>镁.铁、镁、锌肥配施对兰州百合根系活力及产量质量具有显著影响,不施肥或过量施肥均会抑制兰州百合的根系活力,降低产量质量.
Abstract
[Objective]To study the effects of combined application of iron,magnesium and zinc fertiliz-ers on root activity,yield and quality of Lanzhou lily,in order to provide a scientific basis for the green and high-yield cultivation technology of Lanzhou lily.[Method]A"3414"orthogonal experimental design was used to determine the effects of combined application of iron,magnesium,and zinc fertilizers on the root ac-tivity,yield,and quality of Lanzhou Lily.[Result]The best effect of mixed spraying of 600 times solution of 5 kg/hm2 of iron fertilizer,800 times solution of 5 kg/hm2 of magnesium fertilizer,and 800 times solution of 5 kg/hm2 of zinc fertilizer on the root vitality,yield and quality of Lanzhou lily is achieved.The fresh and dry yields were 5 864.8 kg/hm2 and 1 646.7 kg/hm2,respectively,increased by 1 238.5 kg/hm2 and 535.3 kg/hm2 compared with the control.Root activity is 127.55 μg/(g·h),increased by 68.68 μg/(g·h)compared to the control group.The contents of rhamnose,xylose,fructose,glucose,sucrose,and extract were 1.069%,1.182%,2.757%,4.519%,11.151%and 44.70%respectively,increasing by 15.06%,74.67%,144.21%,44.50%,84.00%and 45.78%compared to the control.[Conclusion]T6 has the best effect,which is a mixed application of 600 times the liquid of iron fertilizer 5 kg/hm2+800 times the liquid of magnesium fertilizer 5 kg/hm2+800 times the liquid of zinc fertilizer 5 kg/hm2 solution.The promoting effect of paired fertilization on root vitality,yield,and quality is from high to low,followed by iron-magnesium>magnesium-zinc>iron-zinc.The promoting effect of single element fertilization on root vital-ity,yield,and quality is from high to low,followed by zinc>iron>magnesium.The combined application of iron,magnesium,and zinc fertilizers has a significant effect on the root activity,yield,and quality of Lanzhou lily,no fertilization or excessive fertilization will inhibit the root activity of Lanzhou lily and reduce the yield and quality.
