摘要:

为了推进湖南饲用大麦(Hordeum vulgare L.)的种植,对冬闲稻田进行有效开发,探索环洞庭湖区大麦栽培抗倒高产节本的栽培措施。本研究使用裂裂区设计的田间试验方法调查不同播种期、不同耕作方式和施肥对大麦产量构成因子如有效穗数、穗粒数和千粒重等的影响。结果表明:洞庭湖区冬闲田种植大麦,不同播种期、耕作方式和施肥对大麦的农艺性状和产量有显著的影响(P<0.05)。在不影响双季稻生产的情况下,播种期最好不要超过11月4日,且翻耕可以显著提高大麦产量(P<0.05),而施肥对大麦产量影响较小,可以考虑不施肥。总体来看,‘华大麦4号’的小区种子产量最高达到9.5 kg每小区,适合洞庭湖区种植并可进行进一步栽培研究。

Abstract:

The aims are to promote the cultivation of Hunan Hordeum vulgare L., develop winter fallow field effectively, and explore the cultivation measures of lodging resistance, high yield and cost saving barley around Dongting Lake area. The effects of different sowing dates, tillage methods and fertilization on yield components such as effective panicle number, grain number per panicle and 1000-grain weight of barley were investigated using the split plot design method. The results showed that when the barley was planted in the winter fallow field, different sowing dates, tillage methods and fertilization affected the agronomic traits and yield of barley obviously (P<0.05). Under the condition of not affecting the double cropping rice production, the sowing date should not exceed November 4, and ploughing could significantly improve the yield (P<0.05), while fertilization had a small impact on the yield, so the fertilization could not be considered. In general, the seed yield of ‘huadamai No. 4’ could reach 9.5 kg per plot, which is suitable for planting in Dongting Lake area.

Key words: barley, sowing date, tillage method, fertilization, agronomic traits
