Mechanization technology for seed corn production in Xinjiang:Detasseling
Xinjiang is an important planting area for seed corn in China,and the removal of male ears from corn females is one of the key aspects of seed corn planting.There are differences in the methods of tassel removal and the use of mechanical tassel removal in different regions due to the influence of planting patterns and technical requirements for tassel removal.Artificial emasculation can be selectively removed based on the growth of the tassel,and 5 to 6 draws are needed for the whole tassel removal period.Mechanical emasculation adopts two methods of direct emasculation or first cut the top and then emasculation,the extraction rate of 80%to 95%.However,mechanical emasculation causes more damage to leaves,and manual inspection and emasculation are required after mechanical emasculation.In order to comprehensively promote the application of mechanical emasculation technology,the planting pattern suitable for mechanized operation,mechanical emasculation technology and the overall performance of destemming machines should be further standardized and improved.
