摘 要: | 在宁夏固原市原州区官厅镇进行了旱地谷子全膜双垄覆盖沟穴播技术效应研究,结果表明:在降雨量400mm的半干旱区,采用全膜双垄覆盖沟穴播技术种植谷子有效地提高了土壤蓄水保墒能力和地积温,促进了谷子增产增收。7种覆膜种植方式中,秋季全膜、早春全膜、全膜覆土穴播增产效果显著,籽粒平均产量超过3900.0kg/hm^2,生物产量超过5625.0kg/hm^2,水分利用率达到60%以上,水分生产效率达到15kg/(mm·hm^2)。

Abstract: | A study was made on the effect of double ridge whole-mulching furrow hole sowing technology for dryland millet in Guanting Township in Yuanzhou district in Guyuan municipality in Ningxia. The result showed that in semiarid area with a yearly precipitation of 400 mm, the adopting of the double ridge whole-mulching furrow hole sowing technology for millet could promote the soil water holding capacity and ground temperature and promote the millet yield. Amo~"g the 7 kinds of mulching and planting methods, the whole-mulching in autumn, the whole-mulching in early spring and the whole-mulching hole sowing performed significant effects in yield increasing, the average grain yield surpassed 3 900.0 kg/hm2, the biological yield surpassed 5 625.0 kg/hm2,the water utilization efficiency reached 60% and the water production efficiency reached 15 kg/(mm·hm2). |
