生物有机肥在茶园的肥效试验

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

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。

For further study on application effect of bin-organic fertilizer in tea garden, the experiment set different treatments in 6 years, 3 years tea garden, compared with conventional fertilization （CKI, CKE）,on this basis, applied bio-organic fertilizer 0.80 kg/hm2, sprayed bacterial liquid 10 mL/hm2 after dormant period （T1, T3） ;applied bin-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 pJhonological phase, the buds germinating 3-5 d earlier than the control; the sprouting stage with l-leaf-l-bud and 2-1ear-l-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.
