洛阳丘陵旱地谷子种植效益分析及栽培技术研究

选择洛阳有代表性的丘陵旱薄地和丘陵旱肥地,调查了谷子的产量和经济效益,并与同等肥力条件下种植玉米的经济效益进行了比较。结果表明:如果选用谷子新品种,单位面积种植效益将是玉米的2.6～2.8倍;即便是生产上种植普通谷子品种,效益也与种植玉米相当,且免去了清理玉米秸秆的巨大劳动量。结合偃师(丘陵旱薄地)、宜阳(丘陵旱肥地)谷子示范县的谷子新品种新技术推广工作,调查了不同种植情况下(种植时间、茬口、谷子品种、施肥情况、留苗密度)的谷子产量,总结了适合洛阳谷子生产的一些关键技术。

Planting Benefit and Cultivation Techniques of Millet on Hilly Arid Land in Luoyang

The yield and economic benefit of millet on hilly arid poor land and fertile land were investigated,and the economic benefit was compared with that of maize under the same fertility.The results showed that the planting benefit of new millet variety was 2.6-2.8 than that of maize,even that of normal variety was equivalent with that of maize,that was to say,the maize straw was not necessary to be cleaned.Combining with the extension of new millet varieties and new cultivation techniques in the demonstration counties in Yanshi,the planting time,rotation systems,varieties,fertilization and density on the yield were investigated.The key cultivation techniques suitable for millet produciton in Luoyang were summarized.
