摘要
针对谷子生产中捉苗难，产量低的问题，将地膜覆盖保水的优点纳入旱地谷子的增产技术体系，从试验研究结果表明，本项措施可以有效地提高休闲期土壤水分含量，为谷子捉全苗打下了坚实的基础，并可改善谷子的生理代谢，促进谷子大幅度提高产量，试验研究为旱地谷子的增产提供了依据。
To solve the problems of low seedling emergence percentage and low yield in millet production, the advantage of film mulching for moisture preservation was considered in a millet yield increasing technique in dryland. The result showed that, with the film mulching method the moisture content of soil in fallow period was raised, the base of total seedling emergence condition of millet provided, the metabolism of millet plant improved, and millet yield greatly increased. The study provided the related technical and theoretical bases for the millet yield increase in dryland.
