摘　　要：【目的】探讨生物有机肥对春茶生长、产量、品质及经济效益的影响,为生物有机肥的推广提供理论依据。【方法】采用微生物好氧发酵技术,分别以鸡粪、玉米秸秆和牛粪、玉米秸秆为主要原料,堆制优质生物有机肥料A和B。以不施肥为对照,研究施用2 250 kg/hm2生物有机肥A和B及施用450 kg/hm2无机复合肥和有机肥等4个不同施肥处理(分别为T1,T2,T3和T4)对春茶产量、品质和经济效益的影响。【结果】施肥能显著提高春茶产量,与不施肥处理相比,T1,T2,T3,T4处理分别增产23.5%,21.8%,15.0%和9.9%;4种施肥处理的茶鲜叶内含物含量均大于不施肥处理;T1,T2,T3,T4和不施肥处理的酚氨比依次为6.65,6.20,7.06,5.72和5.77;与T3处理相比,T1,T2和T4处理分别增收15.54%,11.49%和0.86%。【结论】堆制的生物有机肥安全、高效,能促进茶树生长,改善茶叶品质,提高茶园经济效益,具有广泛的推广价值。[Objective] This experiment studied the effect of bio-organic fertilizer application on grouth,yield and economic effectiveness of spring tea, to provide theoretical foundation for the generalization of bio-organic fertilizer. [Method] Using technique of compost fermented by aerobic microbe, high quality Bio-organic fertilizer A and B were composted by using chicken manure, and corn stalk and cattle manure,corn stalk as raw material, and the effects of 2 250 kg/hm^2 bio-organic fertilizer A and B, 450 kg/hm^2 inorganic complex fertilizer and organic fertilizer （T1 ,T2 ,T3, T4 ） on yield, quality and economic effectiveness of spring tea were analyzed, and compared the effect with no fertilizer. [Result] Fertilization could significantly increase spring tea yield, compared with no fertilizer, T1 , T2, T3, T4 respectively increased yield by 23.5% ,21.8%,15.0% ,9.90% ;The nutrient content in fresh tea-leaves of 4 different fertilization treatments was higher than that of no fertilizer; The P/A of T1 , T2, T3, T4 and no fertilizer trentments were respectively 6.65,6.20,7.06,5.72,5.77 ; Compared with T3, the annual production income of T1 ,T2 ,T4 were increased by 15. 54% ,11. 49% and 0. 86%. [Conclusion] The composting bio-organic fertilizer is safe and effective, and can promote growth of tea plant, improve quality of tea, increase economic benefits, hence it is worth to be widely spread.
