摘要:

为探究岩棉水肥一体化技术在茶园的应用效果与潜力,以浙江省安吉县灵峰寺林场茶园基地为研究对象,设置常规施肥对照,分析岩棉水肥一体化处理对0~10、11~20和21~40 cm土层土壤胞外酶活性(extracellular enzyme activities,EEAs)、养分含量及其他化学性质的影响。结果表明,与常规施肥相比,岩棉水肥一体化处理提升了深层土壤有机碳和养分含量,且降低了3层土壤中纤维素二糖水解酶、β-1,4-葡萄糖苷酶、β-1,4-木糖苷酶、β-N-1,4-N-乙酰基氨基葡萄糖苷酶、酸性磷酸酶的活性。综上,应用岩棉水肥一体化技术能够有效缓解茶园深层土壤养分限制,有利于作物生长。

Abstract:

By revealing the effects of rockwool water-fertilizer integration technology(RWFIT)on extracellular enzyme activities(EEAs)and nutrients in different soil layers of tea plantations,this study preliminarily explored the application effectiveness and potential of this technology in tea cultivation. We investigated the soil EEAs,nutrient content,and other chemical properties at different depths(0-10,11-20,and 21-40 cm)under the application of RWFIT in Lingfengsi Forest Farm Tea Plantation,Anji County,Zhejiang Province. The results showed that the RWFIT enhanced organic carbon and nutrient content in deeper soil layers while reducing the activities of cellobiohydrolase,β-1,4-glucosidase,β-1,4-xylosidase,β-N-1,4-N-acetylglucosaminidase,acid phosphatase across the three soil layers,indicating its potential to effectively alleviate nutrient limitations in deep soil layers and promote crop growth. This study provided a theoretical foundation for the future application and promotion of this technology in agricultural and forestry soils.

Key words: soil extracellular enzyme activities, rockwool water-fertilizer integration technology, tea plantation, soil nutrient, soil organic carbon
