茶园土壤有机肥施用效应和施肥技术

Application effect and fertilization technology of organic fertilizer in tea garden soil

茶园土壤施用有机肥在提高土壤肥力、增加茶叶产量和改善茶叶品质方面具有积极效应,同时也应注意施用有机肥带来的安全性风险。对茶园施用有机肥的作用、施肥技术与安全性风险进行研究发现,茶园施用有机肥能改善土壤理化性状和土壤生物环境,促进茶树生长及提升茶叶品质。有机-无机肥料配合施用是适宜现代化绿色、安全、可持续发展茶园的施肥模式。畜禽粪便生产的有机肥存在含有重金属、抗生素和激素残留的现象,茶园施用动物源有机肥存在环境和健康风险。基于以上研究,展望了茶园土壤有机肥施用的研究方向,为茶园土壤推广和应用有机肥提供科学依据。

The application of organic fertilizer in tea garden soil has a positive effect on soil fertility,tea yield and tea quality improvement.At the same time,more attention should be paid to the risk of tea safety brought by organic fertilizer.This paper studies the effects of organic fertilizer,fertilization technology and risk of tea safety on organic fertilizer application in tea garden.The results show that the application of organic fertilizer in tea garden has a great influence on soil physical and chemical properties as well as the biological environment,promote the growth of tea trees and improve the quality of tea leaves.The combined application of organic with inorganic fertilizer is suitable for modern green,health and sustainable development of tea garden.Heavy metals,antibiotics and hormone residues exist in the organic manure produced by livestock and poultry manure,application of animol-derived organic fertilizer in tea gardens has environment and health risks.Based on the above research,this paper prospect the theoretical research direction of organic fertilizer application in tea garden soil,meanwhile,provide scientific basis for the promotion and application of organic fertilizer in tea garden soil.
