不同灌溉方式下冬小麦穗部性状与产量关系的试验研究

Relationship between Winter Wheat Yield and Panicle Traits under Different Irrigation Modes

采用田间试验,以豫麦69为试验材料,研究了不同水分处理下常规灌溉和一体化垄作沟灌的冬小麦产量与穗部性状的相互关系。结果表明,同常规灌溉方式相比,一体化垄作沟灌方式下,冬小麦的穗粒数、籽粒质量及产量分别增加了5.5356%、7.5489%、7.7454%,但穗数减少了0.4302%。常规灌溉和一体化垄作沟灌方式下,产量与穗数、穗粒数以及籽粒质量均正相关,但一体化垄作沟灌方式下的相关系数较常规灌溉方式大。一体化垄作灌溉有利于改善农田小气候、发挥作物的边行优势和提高小麦产量。

With the Yumai 69 as test materials,field experiments were conducted to study the relationship between winter wheat panicle traits and yield under conventional irrigation and integration ridge tillage furrow irrigation.The results showed that,compared with conventional irrigation methods,spike grain number,grain weight and yield increased by 5.5356%,7.5489% and 7.7454% respectively,but the panicles reduced by 0.4302% under integration ridge tillage furrow.Under integration ridge tillage furrow irrigation and conventional irrigation,yields were all positively correlated with the panicles,spike grain number and grain weight,but the correlation coefficient under furrow irrigation was bigger compared to conventional irrigation.The integration of ridge tillage irrigation was advantageous to improve the field microclimate,make full use of the advantages of crop boundary line,and improve the wheat yield.
