摘要: 试验为选取有效耕作方式及合理种植密度指导玉米生产,以德美亚3为试验材料,研究不同耕作方式和密度对玉米的产量,产量构成因素及主要农艺性状的影响。结果表明:相同密度下,免耕平作(T1)玉米产量高于秋翻平作(T2)和传统垄作(T3),前两者差异不显著,与后者产量差异达极显著水平;相同耕作方式下,随着密度的增加产量呈先增再降的趋势,D2处理产量最高,与D3差异不显著,D2、D3处理大于D1处理,但与D1处理差异达到极显著水平;相同密度下,免耕平作处理穗粒数、穗粒重最高,倒伏率、空秆率较低。

Abstract: We did the experiment to guide the corn production by choosing effective cultivation mode and reasonable planting density.We used Demeiya3 as test material to study the effects of cultivation modes and planting densities on corn yield ,yield components and main agronomic traits.The results showed under the same planting density the yield of T1 treatment was higher than T2 and T3 treatments,The yield difference between T1 and T2 treatment was not significant,but greatly significant with T3 treatment.Under the same cultivation mode,the yield firstly increased then decreased with the density increasing and the D2 treatment had the highest yield,the difference between D1 and D2、D3 was significant, the difference between D2 and D3 was not siginificant.Under the same density,T1 treatment had highest grain number per spike,grain weight per spike and lowest lodging rate, empty stalk rate.
