春花生高效量化施肥计算机咨询系统基本原理与应用研究

The Principle and Application of Computer Consultant System for Quantified Fertilizer-application with High Benefit in Spring-planting Peanut

春花生量化施肥咨询系统是在多年高产栽培、平衡施肥试验以及与其相配套的多种技术试验研究基础上建立的。该系统充分考虑了农业措施对肥料决策的影响,并通过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,从而确保了咨询系统决策结果的准确性和经济性。该系统用VisualBasic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。为花生精确施肥提供了有效途径。经烟台、青岛等花生主产区应用,增产荚果480～690kg/hm2,增效1620～2340元/hm2。

A quantified fertilizer application computer consultant system on spring-planting peanut was set up based on several year results of high yield culture, balanced fertilizer application and corresponding trials. This system fully considered the effect on fertilizing decision produced by agricultural actions and concluded the method of decision on appropriate target yield through the synthesized effect on crop yield produced by soil and agricultural actions, and so guaranteed the accuracy and economy of the decision result produced by the consultant system. The system was programmed with Visual Basic and it's interface is simple and convenient to operate. The system supplied an effective way to accurate fertilizer application on peanut. It increased pod yield of 480～690 kg/ha and profit of 1620～2340 yuan/ha through its application in main peanut production areas.
