Application Effect Of Bio-Organic Fertilizer On Spring Tea | 生物有机肥对春茶的肥效研究

chinois. 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。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。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%。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。

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. 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/hm2 bio-organic fertilizer A and B, 450 kg/hm2 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. 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%, 9.9%; 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 treatments 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%. 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.
