Abstract

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.
