【摘要】 本研究以水稻土植棉系统为例证,利用经验模式及一九八四年正交试验结果,进行了通用旋转组合设计的田间试验;建立了籽棉产量等十项性状依因子水平而变化的四元二次回归方程;通过电子计算机的模拟寻优,获得了高产农艺组合方案,特别对多目标约束条件下的优化方案进行了探讨;通过对因子主效应、交互效应的分析,找出影响水稻土植棉的主导因子以及因子间的配合关系,为农艺决策提供了科学依据。棉花生产是由各种自然条件、经济目的及技术条件等构成的多目标系统。为了对该系统进行深入的认识,需要作定性和定量相结合分析,使这一多目标系统达到协调一致。本试验是在我校水稻土上进行的,采用品种为豫棉一号。计算机运算由江西农大计算机中心进行。更多还原

【Abstract】 This paper makes a demonstration of cottongrowing system in paddy soil.Field trials were made by following rotation combination design according to the“Empirical Model”and the results of the orthogonal experiment,in 1984.Thefour-factor quadratic regression equations which show ten economic charactersincluding the seed cotton out-put were set up separately.The agronomic schemesfor high yields were produced by computer simulation and sieving,especially,the optimal plans under multiple objective contrarieties were approached.Themain factors which affect growing-cotton in paddy soil and their combinativerelation were found out through analysing the main mutual and marginal effectsof the four factors selected.All this provides the scientific basis for agronomicdecision.更多还原
