| Abstract: | The results of this study suggested that the optimum number of fundamental seedling of yumai No.18 in high yielding culture was 120-140 thousands for sowing on 12, October.In order to meet the yield of 500kg per mu ( 0.0667ha. ), the number of ear per mu and kernel per ear should be 420-450 thousands and 28-30 respectively. The suitable proportinon of the number of fundamental seedling, stem in overwinter period, stem in jointing stage and ear at harvest was 1 : 5.7 : 6.5 : 3.4 |
