摘要
为分析动物源营养液在空气凤梨上的应用效果,以'卷叶霸王'空气凤梨为研究对象,以清水作对照,研究动物源营养液、磷酸二氢钾、尿素喷施后对空气凤梨新叶生长、单株增重、光泽度及矿质元素含量等的影响.结果表明,动物源营养液中含有钙、镁、铁、锌、硼和锰等矿质元素,空气凤梨在各种处理后 3 月内都没有新根萌出,均未出现肥害与微量元素中毒现象,光泽度没有明显差异.2.50‰营养液处理的第 1 小叶生长率增加 41.58%,增加幅度最大.0.10‰动物源营养液处理单株增重率最高,2.50‰、0.50‰营养液处理次之;不同浓度动物源营养液处理间单株增重率差异不显著.与CK相比,3.33‰营养液处理、1.00‰营养液处理显著增加空气凤梨新叶内钙、镁、铁和锰含量,3.33‰动物源营养液处理的钙含量增加 27.80%,镁含量增加 23.71%,铁含量增加 10.75%,锰含量增加 104.41%.3.33‰营养液处理新叶内钙、镁、锰和硼含量显著高于 1.00‰营养液处理,但铁和锌含量显著低于 1.00‰营养液处理,生产上可以将动物源营养液作为卷叶霸王空气凤梨新型叶面营养肥进行合理开发与利用.
Abstract
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.
