河西灌区玉米产量和品质对不同覆膜方式的响应
Response of Maize Yield and Quality to Different Mulching Methods in the Hexi Irrigation Areas
摘要
Abstract
This study investigated the effects of different mulching methods on maize agronomic traits,yield,and grain quality,aiming to achieve increased yield,improved quality,and enhanced production efficiency,and to address key challenges in field crop production research in irrigated areas of Northwest China.4 treatments were evaluated,i.e.,no fertilization without mulching,fertilization without mulching,fertilization with strip mulching,and fertilization with full mulching,variations and correlations in maize yield and its components as well as grain quality were analyzed among treatments.Results showed that plastic mulching significantly improved yield components,fertilization with full mulching had the most pronounced effect on yield,in which the yield was increased by 114.56%compared with that in no fertilization without mulching,grain crude protein yield,ether extract yield,and starch yield were increased by 149.39%,127.64%,and 108.52%,respectively compared with those in no fertilization without mulching.Fertilization with strip mulching increased yield by 112.86%compared with that in no fertilization without mulching,while grain crude protein yield,ether extract yield,and starch yield were increased by 142.13%,133.52%,and 108.61%,respectively compared with those in no fertilization without mulching.Both fertilization without mulching and fertilization with plastic mulching improved maize yield by enhancing agronomic traits such as plant height,stem diameter,and ear diameter,thereby improving grain quality.Considering yield performance and environmental benefits comprehensively,fertilization with strip mulching was identified as an effective approach for achieving high-yield and high-quality maize production in the region.关键词
