Abstract

Taking Zhongyu 3 as the experimental variety, this paper analyzed the effects of different sowing depths (5 cm and 8 cm) and sowing equipment (ZHSB-10 medium-sized sowing machine and 2B-2 small sowing machine) on the growth, yield and components of yield of mechanized sowing maize, to provide references for mechanized maize production in southwest ecological zone. The results showed that the germination rate, plant height uniformity, and most agronomic traits of maize plant were higher at the sowing depth of 5 cm; with the growth of the maize, the effects of the sowing depth on agronomic traits of maize gradually declined; the effects of the sowing depth on the empty stalk rate, double ear rate, lodging rate, and lodging and stem broken rate were smaller; the sowing depth of 5 cm could increase the yield of mechanized sowing maize and most yield traits of maize. Different sowing machines had smaller effects on the germination rate, plant height uniformity, and agronomic traits of all growth stages, empty stalk rate, double ear rate, lodging rate, lodging and stem broken rate, yield, and components of yield of mechanized sowing maize.
