摘要：

为明确河套地区不同栽培模式对'张杂谷19号'产量的影响,以新抗旱谷子杂交种'张杂谷19号'为试验材料,研究3种种植方式（干旱无膜、干旱覆膜及灌溉无膜）和5种密度（4.5万、9万、13.5万、22.5万、45万株/hm2）对'张杂谷19号'稳产和丰产性的影响。结果表明,正常灌溉条件下,'张杂谷9号'的产量随着种植密度的增加而增加。当密度为45万株/hm2时产量最高,达到8724.36 kg/hm2。而干旱条件下,适宜种植密度可以同样获得较高产量,与正常灌溉条件下最高产量差异不显著。当种植密度为9万~ 45万株/hm2时,产量普遍提高到7700 kg/hm2以上,最高可达8654.33 kg/hm2。河套地区'张杂谷19号'播前灌溉1次足水、地膜覆盖及种植密度9万~45万株/hm2,可以实现水分高效利用和产量达到较高水平。

Abstract:

To understand the effect of different plant models on the yield of new drought-resistant hybrid millet 'ZZG 19' in Ordos region,3 plant patterns (drought and no plastic film, drought and plastic film, irrigation and no plastic film) and 5 plant densities (45000, 90000, 135000, 225000 and 450000 plants/hm2) were designed to study the stable and high yield ability of the hybrid millet 'ZZG 19'. The results showed that: the yield of 'ZZG 19' was improved with the increase of planting density under normal irrigation condition, and the highest yield was 8724.36 kg/hm2 at 450000 plants/hm2. Under drought condition, higher yield could be obtained by suitable planting density. When the planting density was 90000-450000 plants/hm2, the yield could be above 7700 kg/hm2, with the highest of 8654.33 kg/hm2, which had no significant difference with the highest yield under normal irrigation. Therefore, the suitable water-saving and high-yield planting mode of 'ZZG 19' in Ordos region is: irrigation of full water once before sowing, plastic film mulching and planting density of 90000-450000 plants/hm2, which could obtain high water use efficiency and high yield.
