摘要
在相同生态条件下 ,研究了人工生态茶园、密植免耕园、常规栽培园 3种主要栽培方式对土壤肥力的影响。结果表明 :人工生态茶园栽培方式不仅能提高土壤肥力 ,而且土壤肥力有上升和富集向上的趋势 ;密植免耕栽培方式 ,土壤肥力也有提高 ,但较人工生态茶园栽培方式差 ;
WT5”BZ]A fire year's follow up monitoring program was carried out on the tea garden in Gui zhou. It was found that, at a same ecological condition, for three main cultivatoion systems had different soil fertilities. The convention cultivation tea gardens resulted in decrease and retrogression of soil fertility. The artificial ecological tea garden bring about good ecological benefit. Under this cultivation system, soil fertility appeared to be in creased. Intensive planting could not only make a full use of the land, but also make the soil fertility increase. However, under the artificial ecological tea graden of intensive planting, soil fertility was relatively low. Comparing all the advantages and disadvantages of three cultivation systems. It is suggested that the artificial ecological tea garden will be a better cultivation system for tea.
