The relationship and optimization analysis between stem structure parameter and yield
Efficient and productive agriculture is the focus of sustainable production.In order to investigate the efficiency of corn stem structure parameter and optimal utilization of production improvement.This research used data acquired from 2015 in Xiaotangshan,Beijing,putting stem structure parameter as input indicators,and biomass,yield,and economic coefficient as output indicators.Data envelopment analysis was used to explore stem structure parameter using efficiency and optimal utilization efficiency.The results show that the utilization efficiencies corn stem structure parameters were all maintained above 0.7,which belong to high utilization level.During the small bell and tasselling stage of the corn,the upper stem stalk has the lowest utilization efficiency,while the lower stem stalk has the maximum utilization efficiency.The best utilization efficiency of corn stem structure parameter took full advantage of resources,and the yield was improved in different degrees,especially during tasselling,which improved 32％.The corn stem structure parameter utilization has not achieved the optimal efficiency,and improving its utilization efficiency can improve yield significantly.
