不同保水剂施用方式对马铃薯生理指标及农艺性状的影响
Effect of Different Application Methods of Super Absorbent Polymer on Physiological Indicators and Agronomic Characters of Potato
摘要
Abstract
The effect of different application methods of super absorbent polymer (SAP) on potato varieties of "cooperation 88" was studied.Several agronomic characters and physiological indicators were used in this field experiment.The results show that the effect of SAP had time bound,different SAP application methods acted in different periods.Seed dressing with SAP was helpful to improve the e-mergence rale.All SAP application methods improved soil moisture content,and hole-used method with SAP at seeding stage had highest soil moisture content.Furrow application with SAP at seeding stage and hole-used method with SAP at seedling stage had better effects on physiological indicators.As a comprehensive assessment,"fuzzy subordination method" results showed that all SAP application methods were better than natural control except seed dressing with SAP method,and hole-used method with SAP at seedling stage was the best SAP application method in this experiment,the assessment index was 71.43% higher than natural control.Hole-used method with SAP at seedling stage improved potato yield,especially improved the yield and quality of large tubers.关键词
