Effect of combined iron-magnesium-zinc application on root activity,yield and quality of Lanzhou lily
[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.
