不同种植密度对超甜玉米产量及相关性状的影响
Effects of planting density on the yield and related characters of super-sweet corn cultivar ‘Xiawang’
摘要
Abstract
The field experiments with sweet corn cultivar ‘Xiawang’were carried out at 5 different planting densities to study the fresh ear yield and main agronomic characters of the cultivar as influenced by planting den-sity.The results showed that under different planting densities the cultivar’s fresh ear yield and characters had obvious differences;The yield increased with the planting density increasing and then decreased when the plant-ing density was beyond a certain extent;The ear length and diameter,ear weight,grains per row,and quality ear rate decreased gradually with the planting density increasing;In terms of the comprehensive agronomic charac-ters,a suitable spring seeding density for the cultivar in Shanghai area was 45 000—49 500 plants?hm2 ,and con-sidering the fresh ear marketability and economic benefit the optimum planting density was 45 000 plants?hm2 .关键词
