江西省红壤旱地多年轮种模式的综合效益评价

南方红壤区是我国重要的经济林果、粮食、渔业、牧业生产基地,为筛选出具有经济、生态、社会效益较好、适合南方红壤区旱地种植的高效模式,根据江西省红壤研究所开展的红壤旱地作物的田间试验,采用2015—2017年江西省红壤研究所5种旱地3年轮作模式的试验数据,开展红壤地区旱作物不同种植模式的评价,运用层次分析法和一致性准则法采用Lingo软件求解,筛选出具有经济、生态、社会效益、综合效益较好的不同种植模式。结果表明,经济效益较好的种植模式为花生—冬闲→玉米(鲜食)—芝麻→花生—玉米(鲜食);生态效益和社会效益较好的种植模式均为花生—芝麻—马铃薯→(春玉米—绿豆)—绿肥→花生—芝麻—马铃薯;综合效益评价较好的种植模式为花生—芝麻—马铃薯→(春玉米—绿豆)—绿肥→花生—芝麻—马铃薯。

Comprehensive Benefit Evaluation Of Crop Rotation Patterns Of Upland Red Soil in Jiangxi

Southern red soil region is an important production base of economic forest, grain, fishery and animal husbandry in China. In order to select the high-efficient cultivation model with better economic, ecological and social benefits, which is suitable for Dryland Cultivation in southern red soil region, the field experiment data of red soil upland crops in three years carried out by Jiangxi Institute of red soil were used from 2015 to 2017. Using the analytic hierarchy process (AHP) and Consistency criterion method to evaluate the different planting patterns of dry crops in the red soil area. The different planting patterns with better economic, ecological, social and comprehensive benefits were selected in turn. The results were as follows: Crop rotation pattern L5 (peanut - winter fallow - corn (fresh food) - sesame - peanut - corn (fresh food)) is the best economic benefits in all patterns; Crop rotation pattern L1(peanut - sesame - potato green manure peanut - sesame - potato) is the best ecological and social benefits in all patterns; The best comprehensive benefits in all patterns is Crop rotation pattern L1(peanut - sesame - potato green manure peanut - sesame - potato).
