Study on suitable harvesting time and grain water content of fresh waxy maize
[Objective]To comprehensively evaluate the grain moisture content and fresh weight of 10 fresh waxy maize varieties,and select the varieties that are suitable for the optimal harvesting period of fresh waxy maize in the Ili River Valley.[Methods]Using 10 fresh waxy maize varieties as experimental materials,comprehensive analysis was conducted on the grain moisture content,fresh weight,dry matter accumulation,and yield of ear harvested at eight stages after pollination of fresh waxy maize.[Results]There were significant differences in fresh ear yield among different varieties.The fresh ear yields of Sukenuo 1801 and Sukenuo 1505 respectively reached 1,215.14 and 1,025.95 kg/667m2,at 25-30 days after pollination,the grain moisture content of each variety ranged from 59.6％to 65.0％,making it the most suitable harvesting period for waxy maize;There was no significant difference in dry matter accumulation among the 10 varieties,but there was a significant difference in fresh weight,the order of fresh weight of 100 grains was as follows:Suken-uo 1505＞Caitiannuo 001＞Sukenuo 1801＞Sukenuo 1901＞Nuoxiang 398＞Xiangtiannuo 968＞Sukenuo 1501＞Sukenuo 12＞Sukenuo 212＞Sukenuo 338,Sukenuo 1505 had the smallest decrease in grain moisture content,which was convenient for extending the harvest period.[Conclusion]Based on comprehensive analy-sis,Sukenuo 1505,Caitiannuo 001,Sukenuo 1801,Sukenuo 1901,and Nuoxiang 389 can be selected as the main fresh maize varieties recommended in the Ili River Valley,the optimal harvest period is 25-30 days after pollination.
