密度和分蘖对超甜玉米‘晶甜8号’产量及相关农艺性状的影响
Effects of planting density and tiller number on the yield and related agronomic characters of super sweet corn ‘Jingtian 8'
摘要
Abstract
Plot experiments with super sweet corn cultivar ‘Jingtian 8' were carried out under different planting densities to study the effects of planting densities and tillers on the yield and agronomic characters of ‘Jingtian 8'.The results showed that with the planting density increasing the yield increased and reached the highest at the density of 75 000 plants/hm2.With the density increasing the plant height,ear height and bald tip length also increased but the ear length,fresh ear weight and tiller number decreased.Appropriately increasing the planting density could made the picking time earlier and the growth duration shorter,which was unrelated to removing tillers or not.At the same planting density,retaining the tiller number resulted in the fresh ear weight and yield decreasing,the plant height and ear height increasing and the ear length and bald tip length shortening,but the differences were not significant.The suitable planting density of ‘Jingtian 8' was about 60 000 plants/hm2,and the tiller number could be retained in production.关键词
