莜麦在河南省的引种与利用技术研究

[目的]研究莜麦在河南省的引种情况及利用技术，为河南省黄河滩区引进和推广来自内蒙古的莜麦品种内农大莜1号和内农大莜2号提供依据。[方法]通过莜麦在河南省黄河滩区气候和土壤条件下的引种试验，研究内农大莜1号和内农大莜2号的适应性、生长特点、生物学规律和生产水平，并与原产地进行比较分析，探索该莜麦品种在河南推广的可能性和必要性。[结果]莜麦引种到河南后，光合能力得到了增强，株高、叶面积指数得到明显的提高，但植株中干物质含量明显降低。内农莜-1和内农莜-2号的秸秆产量分别为1578．4、1462．7g DM／m^2，分别比原产地提高33．3％和21．6％；果实产量分别为457．6、481．7gDM／m^2，分别比原产地提高20．8％和26．0％。[结论]内农大莜1号和内农大莜2号能很好地适应河南省黄河滩区的土壤和气候条件，并且生长快、产量高，能表现出比原产地更高的生产性能，适宜在黄河滩区推广和利用。

Studies on Introduction and Utilized Techniques of Naked Oat(Avena nuda Linn.) in Henan Province

[Objective]The research aimed to study the introduction and utilized techniques of Naked Oat(Avena nuda Linn.) in Henan Province,provide reference for popularizing and applying 2 species of Naked oats(Neinongda Oats-l and Neinongda Oats-2) from Inner Mongolia to Henan Yellow River beach.[Method] 2 species of nude oats,Neinongda Oats-l and Neinongda Oats-2,were introduced to Henan Yellow River beach to study adaptability,growth characters,biological principles and productivities,and approached possibilities and necessities of extension of Naked Oats in Henan Province by introduction trials.[Result] The photosynthetic ability,plant height and LAI of Neinongda Oats-l and Neinongda Oats-2 were all enhanced and dry matter rates were decreased when Naked Oats were introduced to Henan Province.Forage yield and grain yield of Neinongda Oats-1 grown in Henan were 1 578.4,457.6 g DM/m2 and increased by 33.3% and 20.8% compared to Neinongda Oats-1 grown in Inner Mongolia.Forage yield and grain yield of Neinongda Oats-2 grown in Henan were 1 462.7,481.7gDM/m2 and increased by 21.6% and 26.0% compared to that grown in the original place(Inner Mongolia).[Conclusion] Neinongda Oats-l and Neinongda Oats-2 could adapt to the soil and climate conditions of Yellow River beach of Henan Province well with quicker growth rate and higher production level,and showed better productivities than that in original place and they were suitable for extension in Henan Yellow River beach.
