低丘红壤花生南酸枣间作试验结果表明:农林间作枣间作有利于促进南酸枣的生长,提高系统生产力。与单作南酸枣相比,间作5龄和9龄南酸枣生物量分别提高42.8%和72.9%。但农林间作会导致花生产量的降低,随着树龄的增加,这种影响愈来愈严重。与花生单作相比,5龄南酸枣间作和9龄南酸枣间作系统中可比种植面积花生产量分别降低了35.9%和44.6%。而且,在农林间作系统中花生产量与其对间作南酸枣带的距离呈显著相关。距离南酸枣带愈近,花生产量愈低。
The results showed that the intercropping of jujube with agro-forestry was beneficial to the growth of S. japonicus and the increase of system productivity. The biomass of the fifth and ninth instar larvae increased by 42.8% and 72.9%, respectively, compared with the single asparagus japonica. However, intercropping with agriculture and forestry will result in a decrease in the yield of peanuts. As the tree ages increase, the impact will be more and more serious. Compared with peanut single cropping, the peanut yield of comparable planting area in the fifth instar and second trimester jujube intercropping system decreased by 35.9% and 44.6% respectively. Moreover, there was a significant correlation between the yield of peanuts and the distance between them in the agroforestry system. The closer to the southern acid jujube belt, the lower the yield of peanut.
