摘　　要：水稻推荐施肥电子计算机专家咨询系统,是以我国北方一季粳稻不同生育时期对于镶素养分的需要和影响土壤供氮能力的多种因素为依据,将专家们多年来的施肥试验结果和经验编成电子计算机程序,用以定量化和科学化的推荐指导水稻合理施肥,使水稻生产达到高产高效益。目前,人工智能在国际上发展十分迅速,其中专家系统的发展更为突出,但在作物施肥上的研究报导很少,国内应用人工智能专家系统确定小麦施肥方案,获得了较好效果,但只作到了确定总施肥量。The advisory computer system(ACE)was established on the basis of 27 factors,which belong to soil,temperature and light conditions,attributes of rice varieties,and vigour characters of rice seedling.These factors affected the nitrogen fertilizer effect in Single-crop Jing rice area in Northern China.They were divided into groups based on different development stages of plants and separetly givin of weight coefficients.ACS was built up in prolog and BASIC language with Great Wall-0520 and Purple Gold-Ⅱ micro- computer.It consists of one main and three auxiliary systems and can be used to determine the total amount of applying uitrogen,phosphorus,and potassium fertilizers as well as the program of applying nitrogen fertilizer in different stages of seedling,tilling,elongating,heading and filling.
