摘要/Abstract

摘要： 应用灰色关联选择受阴害水稻的主要受害指标,以层次分析法和模糊综合评判分析了化学调控剂对减轻水稻在抽穗灌浆期不同时段阴害的效应.结果表明,阴害危害的最大3个指标为结实率、净同化率和根系活性强度;在水稻抽穗后6～20d出现阴害时,喷施化学调控剂的增产效果最明显,隶属度达0.7869.

Abstract: Main indexes of rice injury by insufficient illumination (Ⅱ) were selected through Gray Relation,and the effect of regulation agent on rice injured by Ⅱ at different stages during heading-filling period was analyzed using Gradation Analysis, Fuzzy Comprehensive Evaluation.The results showed that the percentage of filled-grain,net assimilation rate, root activity were the top three indexes subject to injury.Application of chemical regulation agent when the injury occured 6～20 days after heading had the best effect,with a degree of subordinacy of 0.7869.
