豫西旱作区旱地小麦高产特性及配套技术探讨

High Yield Characteristics and Cultivation Techniques of Dry Cultivation Area in Western Henan Dryland Wheat

以旱地小麦区试对照品种洛旱7号为材料,以"1235"旱地小麦高产栽培技术模式为依托,研究旱地小麦高产特性及配套的栽培技术,以期带动和提升中低产田的产量水平,为豫西旱地乃至全国的旱地小麦高产提供技术依托。结果表明,洛旱7号在豫西旱地2 a能取得7 500 kg/hm2以上的产量,得益于合理的群体结构,适宜的LAI,较高的籽粒干物质积累速率及WUE。并总结出了洛旱7号的高产栽培指标及配套高产栽培技术。

The paper studied on the high yield characteristics of Luohan 7, to stimulate and improve production levels in the low- yield fields, and provide technical support for high- yield and drylands in Western Henan dryland and the country＇s dryland wheat.The results showed that the yield of Luohan 7 obtained 7 500 kg/hm2 above the output in Western Henan dryland for two years, thanks to a reasonable population structure, appropriate LAI, higher grain dry matter accumulation rate and WUE. And the cultivation of high yield index and high yield cultivation techniques of Luohan 7 were summarized.
