摘要
通过一年半的对比试验与跟踪调查,从不同角度研究了一种茶树专用肥"茶宝保"对成龄采摘茶树的生长发育影响。结果表明,施用"茶宝保"牌茶树专用肥能够促进茶树早发芽,提高茶芽密度,增加百头芽重和叶片厚度,提高茶叶产量及茶农经济效益等。在推荐施用量的条件下,与当地茶农常规施肥(处理D)相比,萌芽密度提高14.9%,一芽三叶期百头芽重增加7.3%,茶树开花结子率降低22.9%,枝梢黑点病减少17.6%,同时降低了茶饼病病情指数,每667m^(2)经济效益增加1246元,明显提升了茶叶品质,改良了土壤结构。
Through a year-and-a-half comparative experiment and follow-up investigation,the effects of a special fertilizer"Cha Bao Bao"on the growth and development of tea trees at the mature age were studied from different angles.The results showed that the application of"Cha Bao Bao"tea plant special fertilizer could promote early germination,increase the density of tea buds,increase the weight of 100 buds and the thickness of leaves,increase the yield of tea and the economic benefits of tea farmers.Under the condition of recommended application rate,compared with the local tea farmers’conventional fertilization(treatment D),the germination density increased by 14.9%,the weight of one bud with three leaves increased by 7.3%,the flowering and seed setting rate of tea tree decreased by 22.9%,the shoot black spot disease decreased by 17.6%,and the disease index of tea cake disease was reduced,and the economic benefit per 667 m^(2)was increased by 1246 yuan,which significantly improved the quality of tea and improved the soil structure.
