摘要
Four crop species were intercropped in fast-growing and high-yielding poplar plantation.After intercropping with different crops,the increments of poplar increased to different extent.Intercropping with watermelon had the best effects.The height,DBH and amount of new breach increased by 21.6%,44.8% and 100% respectively.The annual net income could be as high as 7 800 yuan·hm^2.
