摘要： 在幼龄茶园套种美洲狼尾草、高丹草和白三叶,比较不同牧草在茶树行间套种的生物产量及对土壤理化性质的影响、对茶园杂草的控制。结果表明:幼龄茶园套种牧草处理中美洲狼尾草生物产量最高,达到597.0 kg·hm-2,套种牧草能有效提高茶园0~10 cm土层的有机质含量,降低土壤容重,其中豆科的白三叶效果明显。与对照相比,幼龄茶园套种牧草不仅能整体提高土壤氮、磷、钾等养分含量,也可以抑制茶园的杂草危害。综上,茶园套种牧草是培肥地力、改善茶园生态的有效措施。

Abstract:

Pennisetum americanum, Sorghum-sudangrass, and Trifolium repens were intercropped with tea trees in young tea plantations to compare their biomass yields, effects on soil physicochemical properties, and weed control efficacy. The results showed that Pennisetum americanum exhibited the highest biomass yield at 597.0 kg·hm-2 among the intercropped forage grasses. Intercropping forage grasses increased the organic matter content in the 0-10 cm soil layer and reduced soil bulk density, with the leguminous Trifolium repens demonstrating the most pronounced effects. Compared with the control, intercropping forage grasses in young tea plantations not only enhanced overall soil nutrient content (nitrogen, phosphorus, and potassium) but also suppressed weed infestation. In conclusion, intercropping forage grasses in tea plantations is an effective measure to improve soil fertility and enhance the ecological environment of tea plantations.

Key words: young tea plantation, intercropping, forage grass, biomass yield, soil properties
