新型水溶肥料对茶叶产量与生化成分影响的灰色关联度分析

摘要

为了探讨不同类型新型水溶肥料对云南茶叶产量与生化成分的影响,应用灰色关联度分析模型对6种新型水溶肥料(含腐植酸水溶肥料、含氨基酸水溶肥料、大量元素水溶肥料、微量元素水溶肥料、含海藻酸水溶肥料和含调节剂水溶肥料)在茶叶生产上的应用效果进行评价.结果表明,从产量性状与生化成分角度看,微量元素水溶肥料增产效果最好,较CK(喷清水处理)增产13.13％；其与理想新型肥料的关联度值最大,加权关联度为0.873 7,等权关联度为0.905 4.从茶叶生产经济效益分析角度看,喷施含腐植酸水溶肥料的产值与利润最高,较CK增加利润5 613.75元/hm2.综合产量、生化成分和经济效益三方面的效果,建议茶叶生产上使用微量元素水溶肥料和含腐植酸水溶肥料.%In order to explore the effect of the new water soluble fertilizer on output and biological component of Yunnan tea, gray relation analysis was applied to evaluate the tea production of 6 new water soluble fertilizers (humic acid water soluble fertilizer,amino acid water soluble fertilizer, microelement water soluble fertilizer,trace element water soluble fertilizer,alginic acid water soluble fertilizer and regulator water soluble fertilizer). The results showed that microelement water soluble fertilizer had the best effect among these samples from the aspect of output and biological composition,and increased the production by 13. 13% compared with control. It had the biggest correlation degree value with new ideal fertilizer,with weighted correlation degree 0. 873 7 and equal correlation degree 0. 905 4. On the other hand,humic acid water soluble fertilizer led the most benefit,increasing by 5 613. 75 yuan/ha from the aspect of economic benefits. Conclusively, microelement water soluble fertilizer and humic acid water soluble fertilizer are recommended to tea production.
