Effect of Planting Density on Yield and Agronomic Characteristics of Xianghuiyu No.1
摘要
Abstract
In order to determine the suitable planting density for the new corn variety Xianghuiyu No.1 and provide a basis for its high-yield cultivation and further promotion,in 2023,using Luoyu No.1 as a control in Liuyang,Hunan Province,5 planting density treatments(45 000,52 500,60 000,67 500,and 75 000 plants/hm2)were set up to compare and analyze the main agronomic characters,yield and yield component factors of Xianghuiyu No.1 under different planting densi-ties.The results showed that with the increase of density,the plant height and ear height of Xianghuiyu No.1 increased,the stem diameter became thinner,the ear length,rows per ear,grains per row and 100-grain mass all showed a downward trend,while the bald tip length showed an increase trend.The yield was the highest at the density of 60 000 plants/hm2,which was 8 235.0 kg/hm2.Under the conditions of this test,the suitable planting density of Xianghuiyu No.1 is 52 500-60 000 plants/hm2 according to the comprehensive analysis.关键词
