旱地谷子地膜覆盖栽培技术的研究与实践

Studies and Applications of Mulching Film Cultivation on Foxtail Millet in Dry Areas

谷子地膜覆盖栽培技术是旱地谷子生产的一项新技术,由于具有明显的增温、集雨、增产、增收效果而在生产上得到推广,但是随着谷子地膜覆盖栽培技术应用的深入,适宜的应用范围、适合的技术模式选择、配套技术的应用、前瞻性技术研究等都成为需要明确和不断完善的问题。系统总结了旱地谷子地膜覆盖栽培技术的研究成果,提出了谷子地膜覆盖栽培技术体系的比较优势,探讨了谷子地膜覆盖栽培技术增产的光、温、水、土效应和谷子生长发育的响应,评价了旱地谷子地膜覆盖栽培技术的增产和增收效果,明确了旱地谷子地膜覆盖栽培技术具有较广阔的应用前景,也分析了谷子地膜覆盖栽培技术的前瞻性研究方向。

Mulching film cultivation in foxtail millet is development technology with advantage of temperature accumulation, precipitation collection and output and profit increase and also is popularized in dry areas in northwest of China. However, with its deeply application, applicable regions, suitable technique choice, matching technology use and prospective technology study should be identified and be perfected constantly. In paper, the results of mulching film cultivation in foxtail millet was systemat- ically summarized; its advantage was recommended; its effects of solar energy, temperature, water and soil and response of foxtail millet were discussed; its increase in output and profit were also evaluated. The paper suggests mulching film cultivation in foxtail millet should be extended in dry areas and also be taken further step in research.
