Application effect of bio-organic fertilizer on spring tea

【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/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.【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%,9.9%;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 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.
