  • Results showed : ( 1 ) if the proportion of water in the soil is lower than wilting coefficient , and if irrigating water is very little , ( irrigating water is spreading horizontally and vertically ) the relationship between the horizontal width ( x ) and the ? rtical depth ( y ) is remarkable . the equation is y - 0 . 02 12x2 + l . 8546x - 17 . 88 . the related coefficient is r = 0 . 9350
    结果表明: ( 1 )在土壤含水量低于萎蔫系数的干燥条件下,进行微量穴滴灌,滴灌点土壤湿润面直径x与最大垂直面渗透深度y呈显著相关,数学模型为: y = - 0 . 0212x ~ 2 + 1 . 8546x - 17 . 88 ,相关系数r = 0 . 9350 ( 2 )在微量补水灌溉情况下,只有灌水量大于4000ml /穴,才能使滴灌水渗透到20cm以下土层,达到作物根系集中层,否则水分很难被作物吸收,造成滴灌水的浪费。
  • Because of the unreasonable restriction of actual models , soil water content at the end of the stage that its sensitivity parameter is small is always close to the wilting coefficient , this makes planting risk . to deal with the planting risk of inadequate irrigation schedule , this paper develops a new multi - objective model for inadequate irrigation schedule programming , and uses the staged multi - dimensional fuzzy optimization method to get the decision - making
    针对现行非充分灌溉制度优化设计模型中约束的不合理性,致使作物在敏感性指数小的阶段末土壤含水率易趋于凋萎系数,生产中存在风险的不足,本文提出了考虑作物种植风险指标情况下,非充分灌溉制度的多目标优化模型;并采用本文提出的多维多目标动态规划方法进行模型求解。
