不同冬播栽培模式对糜子生长特性及产量的影响

Effects of Different Cultivation Patterns in Winter on Growth Characteristics and Yield of Broomcorn Millet

为了充分挖掘冬播糜子的生产潜力,以固糜21号为供试材料,以露地春播为对照(CK),设置膜侧冬播(D1)、平覆膜冬播(D2)、露地冬播(D3)3种处理,分析不同冬播栽培模式对糜子生长特性及产量的影响。结果表明,与CK相比,D1~D3处理,出苗率达到90%以上,生育时期提前8~59 d,生育期延长34~44 d,产量性状不同程度提高,产量增加15.04%~23.34%,其中膜侧冬播表现最高为5215.95 kg/hm~2,可作为糜子冬播的主要栽培模式。

In order to fully explore the production potential of broomcorn millet in winter, with Gumei 21 as test material and spring sowing in open field as control(CK),three winter sowing treatments including plastic film-side(D1), plastic film-coverage(D2) and open-field(D3) were set up to analyze the effects of different cultivation patterns on growth characteristics and yield. The results showed that compared with CK, the seedling emergence rate of treatments D1-D3 reached more than 90% and the growth period was 8 ~ 59 d in advance, the growth period was 34 ~ 44 d longer, and the yield and traits were improved to different degrees, the yield increased by 15.04% ~ 23.34%, the planting on the side of the plastic film showed the highest performance of 5215.95 kg/hm~2, which could be used as the main cultivation pattern for broomcorn millet cultivation in winter.
