摘要：

通过对安溪县感德镇茶园基地高密度(80%-95%)、低密度(30%-50%)马唐与铁观音茶树复合生长系统的生态效应观测,结果发现:高密度马唐生长环境下,茶园温度较纯茶园降低1-2℃,湿度明显增加;生物种群上呈现多样化,并能够有效减少害虫数目,增加天敌数量,而低密度马唐环境下次之,无草条件下最差;在土壤方面,通过留长马唐土壤的容重降低24%,土壤孔隙度增加近22%,改善了茶园土壤结构;留长马唐还可以提高茶鲜叶水浸出物含量,氨基酸含量增加50%,茶多酚减少16%,降低酚氨比。

摘要：

In order to explore the new Anxi local green manure in tea garden, has nearly 10 kinds of tea common grass species were observation and analysis, ultimately determine the Digitaria sanguinalis(L.) Scop. as the research object and carry out tests.This experiment selected Anxi tea Gande Huaizhi tea garden as the experimental field,finding different growth density of Digitaria sanguinalis(L.) Scop. as experimental plots in the natural growth state,and taking them as three groups, respectively is: high density crabgrass growth area and low density crabgrass growing area, no growth of Digitaria sanguinalis(L.) Scop.(no grass) region. By observing the study found that: high density of Digitaria sanguinalis(L.) Scop. growth environment, ecological better, species diversified, and the ability to control pests and their natural enemies,in low-density is the next, no grass under the worst; In terms of soil condition, through to keep long Digitaria sanguinalis(L.) Scop, soil bulk density decreased about 24%, soil porosity increased by nearly 22%, the tea garden soil structure and the soil water storage capacity are improved; For the influence of the tea quality, keep long Digitaria sanguinalis(L.) Scop. can improve the tea water extract content and the tea amino acid content increased about 50%, while the polyphenols decreased by 16%. That can decrease phenol ammonia ratio.
