Abstract

The study on the ecological effects of intercrops in four cropping patterns showed that with the increase of multiple cropping, the annual increase of soil organic matter, total N, total P and total K was 5% - 20%, 7% - 40%, 8% - 70% and 15% - 80%, respectively. Potato-soybean had the best benefit in soil and water conservation, followed by cole-peanut, potato-watermelon, and wheat. Compared with control, the average soil erosion module and runoff amount of 4 patterns were decreased by 44.19%, 39.55%, 38.24% and 37.56%, and 22.40%, 9.28%, 24.11% and 21.16%, respectively. Cole-peanut had the highest biomass, being averaged 100 276 kg . hm(-2) annually, and the second was potato-watermelon, with an average of 73 692 kg x hm(-2). Potato-watermelon had the highest productivity, which averaged 37 565 kg x hm(-2) annually, and the second was potato-soybean, averaged 25 934 kg x hm(-2). The efficiency of energy input was in order of cole-peanut, potato-watermelon, potato-soybean, and wheat, and the value was 2.96, 2.08, 2.01 and 0.96, respectively.
