发展三熟制不仅需要适宜的自然生态条件,而且要有一定的社会经济技术条件,其制约、影响因素多,关系复杂,且作用大小不一。为了综合地评价和比较浙江北部平原稻区稻田“两水一旱”和“二旱一水”三熟制的生态适应性,本研究通过田间试验(1987～1988,绍兴市农科所)和广泛的调查,在系统分析6种不同种植制度对气候、土壤、社会经济技术条件的需求及其生态、经济、社会效益的差异的基础上,选择26个评价因素,应用层次分析法和综合评分法,全面地评价了不同种植制度的生态适应性。研究分析结果表明:6种种植制度中,(鲜)蚕豆—早稻—秋玉米的总生长期短,所需的有效积温少,化肥、农药和资金的需求量低;大麦=春玉米+春大豆—晚稻的总生长期 The development of the three-cropping system not only requires suitable natural and ecological conditions, but also has certain social, economic and technological conditions. The constraints and influencing factors are numerous, the relations are complex, and the functions vary in size. In order to comprehensively evaluate and compare the ecological adaptability of the “two water and one drought” and “two dry and one water” three-cropping systems in paddy fields in the northern plain of Zhejiang Province, the study was conducted in field trials (1987 ~ 1988, Shaoxing Agricultural Science Institute) Based on systematic analysis of the needs of six different cropping systems for climate, soil and socio-economic and technological conditions and their differences in ecological, economic and social benefits, a total of 26 evaluation factors were selected and applied by AHP and comprehensive evaluation Act, a comprehensive assessment of the ecological adaptability of different planting systems. The results showed that the total growth period of (fresh) broad bean - early rice - autumn maize was low, the required effective accumulated temperature was low and the demand for chemical fertilizers, pesticides and capital was low; the barley = spring maize + spring soybean The total growth of late rice
