Effects of Spraying Animal-derived Nutrient Solutions on New Leaf Growth and Mineral Element Contents in Tillandsia Xerographica
To determine the effects of animal nutrient sources in the application of Tillandsia xerographica,'curly leaf bully'air bromeliad was used as the research object,and the impacts of animal nutrient sources,potassium dihydrogen phosphate,and urea spraying on T.xerographica new leaf growth,weight gain of a single plant,glossiness,and mineral element content were studied.The results revealed that the nutrient mixture of the animal source contained Ca,Mg,Fe,Zn,B,Mn,and other mineral elements.T.xerographica in the various treatments three months after the emergence of no new roots presented no fertilizer or trace element poisoning,and there was no significant difference in glossiness.In the 2.50‰ nutrient solution treatment,the 1st leaflet growth rate increased by 41.58%,with the greatest increase.In the 0.10‰ nutrient solution treat-ment,the weight gain rate of a single plant was the highest,followed by the 2.50‰ and 0.50‰ nutrient solution treatments;however,the differences in the weight gain rates of the single plant in the different nutrient solutions were not significant.In the 3.33‰ nutrient solution treatment,the 1.00‰ nutrient solution treatment significantly increased the air content of new pineapple leaves,with the contents of Ca,Mg,Mn,and BCa increasing by 27.80%,the Mg content increased by 23.71%,the content of Fe increased by 10.75%,and the Mn content increased by 104.41%,respectively.The 3.33‰ nutrient solution treatment significantly increased the Ca,Mg,Mn,and B contents in the new leaves compared with those in the 1.00‰ nutrient solution treatment.However,the Fe and Zn contents were significantly lower than those in the 1.00‰ nutrient solution treat-ment.The production of the animal source of the nutrient solution can be used as a new foliar nutrient fertilizer for T.xero-graphica curly leaves to carry out rational development and utilization.
