小麦花生两熟制一体化高产高效平衡施肥技术研究

Studies on the balanced fertilization techniques for integrated cultivation of high yield and benefit in wheat peanut cropping system

将小麦花生两作视为一项整体工程，经研究建立了麦油两熟制一体化栽培平衡施肥决策系统。该系统充分考虑了土壤、作物产量、栽培措施等对肥料决策的影响，并通过气候、土壤及农业措施等对作物产量的综合影响，总结出确定适宜目标产量的方法，确保了系统决策结果的准确性和经济性。该系统用ＢＡＳＩＣ语言编制而成，用户可直接进行人机对话，操作简单，使用方便。山东、河南两省５ 县（市）４ 年（１９９５～１９９８）１７６个定点农户使用结果表明，小麦、花生分别平均增产９．１％ 和１２．５％

Based on a large number of integrated and balanced fertilizer application trials (5 years), a balanced fertilizer decision making system for the integrated cultivation in wheat peanut cropping system was studied and established. In this system, numbers of factors influencing fertilizer decision making, such as soil, crop yield level and cultural pratices were fully considered. A method to determine the suitable target yield was developed, which assured the accuracy and high benefit of the decision making results. This system was compiled with BASIC language. Users can dialogue with the computer directly. Yields of wheat and peanut were increased, on the average, by 9.1% and 12.5% respectively, based on the 4 years (1995～1998) data from 176 fixed farmers' fields in 5 counties of Shandong and Henan province.
