生物有机肥在茶园的肥效试验

为进一步探讨生物有机肥在茶园上的使用效果,在6年、3年生茶园设计不同的处理,以常规施肥为对照(分别为CK1、CK2),在常规施肥的基础上施生物有机肥0.80 kg/hm2、休眠期后喷施生物菌液10 mL/hm2(分别为T1、T3),施生物有机肥0.80kg/hm2、休眠期后喷施生物菌液10 mL/hm2(分别为T2 、T4),观测茶树乌牛早物候期、百芽重、发芽密度等指标.结果表明:无论是在6年生茶园还是3年生茶园,施用生物有机肥、休眠期后喷施菌肥对茶树物候期影响效果明显,与对照相比茶树芽萌动提前3～5 d;一芽一叶期和一芽二叶期比对照提早2～4 d:施生物有机肥、休眠期后喷施菌肥能显著提高春茶产量,与对照相比,T1、T2、T3、T4处理分别增产38.3％、13.6％、27.4％和17.1％,以T1处理芽萌发最早、产量最高.

Study on application effect of bio-organic fertilizer in tea garden

For further study on application effect of bio-organic fertilizer in tea garden,the experiment set different treatments in 6 years,3 years tea garden,compared with conventional fertilization(CK1,CK2),on this basis,applied bio-organic fertilizer 0.80 kg/hm2,sprayed bacterial liquid 10 mL/hm2 after dormant period(T1,T3);applied bio-organic fertilizer 0.80 kg/hm2,sprayed bacterial liquid 10 mL/hm2 after dormant period(T2,T4),observed the phonological phase,weight of 100 buds,density of buds of Wuniuzao.The results showed that applied bio-organic fertilizer and sprayed bacterial liquid had a significant influence on phonological phase,the buds germinating 3～5 d earlier than the control;the sprouting stage with 1-leaf-1-bud and 2-leaf-1-bud was 2～4 d earlier than the control;applied bio-organic fertilizer and sprayed bacterial liquid could significantly increase spring tea yield,compared with the control,T1,T2,T3,T4 respectively increased yield 38.3%,13.6%,27.4%,17.1%,T1 had the earliest germinating and the highest yield.
