摘要
伊犁河谷是新疆的主要粮食基地,随着市场需求变化和农区畜牧业发展的需要,伊犁河谷玉米种植面积呈现出井喷式发展.从2007年的6.93×104hm2增加到2022年2.41×105hm2,增幅达到248.2%.伊宁县是伊犁河谷玉米种植大县,玉米种植面积4.7～5.3×104hm2,2016年由于玉米螟大发生导致产量严重下降到504kg·667m-2.本文从气候条件、玉米螟越冬基数等方面进行分析,阐明伊宁县玉米螟大发生的原因,并从玉米产量的变化对防治措施和防治效果进行论述.
Abstract
Ili Kazakh Autonomous Prefecture River valley is a main food base in Xinjiang.From 6.93×104 hm2 in 2007 to 2.41×105 hm2 in 2022,an increase of 248.2%.Yining County is a major corn planting county in the Ili Kazakh Autonomous Prefecture River valley.The area under corn cultivation is 4.7×104-5.3×104 hm2.The yield per hectare increased from 715 kg·667m-2 in 2003 to 916 kg·667m-2 in the 2021,and the yield increased by 28.1%.In 2016,the yield per unit area decreased to 504 kg·667m-2.This paper an-alyzed the meteorological data and the wintering base of the corn borer to elucidated causes of corn borer outbreak and the effect of the yield.The control measures and effect were discussed from the change of maize yield.
