摘要: 对沿江低丘李园4种优化模式的间作物生态效应分析表明,随重复种植的增加,4种间种模式土壤的有机质年均增加5%~20%;全N年增加7%~40%,全P年增加8%~70%,全K年增加15%~80%;全垦种植的土地水土流失严重,土壤侵蚀和地表径流第1年平均达1415.2t·hm-2和790.7m3·hm-2;水土保持最好的是马铃薯+毛豆,其次为油菜+花生、马铃薯+西瓜、小麦;土壤平均侵蚀量和地表径流量与对照相比分别降低44.19%、38.24%、39.52%、37.56%和22.40%、9.28%、24.11%、21.16%.4种模式中油菜+花生生物量最高,年均达100276kg·hm-2,其次是马铃薯+西瓜,年均达73692kg·hm-2;生产力最高的是马铃薯+西瓜,年均达37565kg·hm-2,其次是马铃薯+毛豆,年均达25934kg·hm-2;投能效率最高的是油菜+花生,年均达到2.96.其次为马铃薯+西瓜、马铃薯+毛豆、小麦,分别为2.08、2.01、0.96.同时,有机、无机能输入效应表明,以生物能为主源输入进行转化利用太阳光能和水土资源,维护了果园生态系统的能量盈余,生态效益较高.

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·hm-2. Potato-watermelon had the highest productivity,which averaged 37 565 kg·hm-2 annually,and the second was potato-soybean,averaged 25 934 kg·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.
