在自然降雨条件下的中南丘陵茶园小区进行定点观测,比较了农民习惯施肥处理(T1)、分别以有机肥代替10%化学氮肥或磷肥(T2、T4)及有机肥代替10%化学氮肥或磷肥+覆盖稻草(T3、T5)对不同形态氮、磷养分径流流失的影响,以期为防控茶园氮磷流失从施肥和茶园管理的角度提供借鉴。结果表明:与T1相比,T2和T4径流量减少15.4%~31.5%(P

Field experiment was conducted in Zhongnan hilly tea garden,and the effects of the farmers used to fertilize treatment (T1),replace the 10％ chemical nitrogen or phosphorus fertilizer with organic manure (T2,T4) and organic fertilizer instead of chemical nitrogen or phosphorus fertilizer + straw covering 10％ (T3 and T5) on nitrogen and phosphorus nutrient runoff erosion were explored.The results showed that compared with T1,runoff of T2 and T4 decreased by 15.4％～31.5％ (P ＜0.05),T3 and T5 reduced by 46.8％～52.9％ (P＜0.01).Compared with T1...
