摘要
为探讨江优919最适宜的栽培密度,开展了15 221株/667m2、13 307株/667m2、11 223株/667m2、8 547株/667m24个不同栽培密度试验。结果表明:在试验设计的密度范围内,江优919栽培密度越大,单产越低,株高越高,穗长越长,总粒数越小,实粒数越少,结实率越低,分蘖率越低,千粒重变小。
In order to explore the most appropriate planting density of Jiangyou 919, 4 planting density of 15221hills/667m2, 13307hills/667m2, 11223hills/667m2, 8547hills/667m2 were tested. The results showed that under the planting density of test, with the increase of planting density, the yield trends decreasing, plant height trends higher, length of spike trends longer, number of grains trends decreasing, total grains trends decreasing, full grain rate trends lower, tellering trends less, grain weight trends decreasing.
