基于熵权的模糊物元模型优选夏玉米沟灌方式
Optimization of fuzzy matter element model based on entropy for summer maize in furrow irrigation
摘要
Abstract
In order to explore the influence of different irrigation treatments on main characters and water use efficiency of summer maize,two kinds of planting pattern (conventional furrow irrigation,CFI and wide-ridge and furrow irrigation,WFI) were compared under different water treatments,and the three irrigation levels (The soil water control limits were respectively set at 60％,70％ and 80％ of field water capacity) were set up.Using the fuzzy matter element model method based on entropy weight and CRITIC,the summer maize morphological indexes of different water treatment plants CFI and WFI planted (plant height,leaf area),yield traits (ear length,ear diameter,100 seed weight and yield) and water use efficiency (production efficiency of water use efficiency,irrigation) were analyzed.The result shows that the WFI planting mode of summer maize is better than the CFI planting mode under the same water treatment condition.For areas with relatively abundant water resources,the WFI-70％ θ irrigation scheme is recommended and the WFI-60％ θ irrigation scheme is recommended for areas where water resources are relatively scarce.The fuzzy matter element model method based on entropy weight and CRITIC is of a certain application value to the main characters of summer maize in furrow irrigation and water use efficiency.This study provides a scientific basis for reasonable irrigation and furrow irrigation in summer maize.关键词
