【目的】研究覆盖稻草与间作白三叶草对亚热带丘陵幼龄茶园的生态综合调控效果及对茶叶品质和产量的影响。【方法】以常规管理茶园（清耕茶园）为对照，连续4a进行大田对比试验，并采用DPS分析软件对数据进行显著性分析。【结果】两种生物措施均降低了土壤容重，增加了土壤有机质含量，影响了土壤养分的供应状况，提高了茶树土壤关键层次（0-20cm）和关键时期（4-6月）的水分含量，获得了不同观察时刻、不同深度土壤温度的多种调控效果，延缓和缩短了高温和干旱时间，抑制了杂草的生长，增加了天敌的种类和种群数量，减少了虫害发生率，促进了蚯蚓的生长，使茶树-立地环境-伴生生物群落处于良好...

[ Objective ] Integrated ecological effects of straw mulching and intercropping with white clover as well as impacts on the quality and yield of tea were studied in young tea plantation in subtropical hilly region. [ Method ] Compared to general tea plantation （i.e. clean tillage tea plantation）, continuous 4 years＇ field contrast experiments have been done and all the data have been analyzed by DPS software. [ Result ] Both of the two biological measures improved soil physical properties and soil fertility. They increased the soil water con...
