According to Table 3,(i) at the three-leaf stage,the plant height,steam diameter,leaf length,LAI,and plant dry weight of maize with sowing depth of5 cm increased by 3.0%,2.8%,2.9%,3.3%and 1.5%compared with the maize with sowing depth of 8 cm;the leaf length of the medium-sized sowing machine ZHSB-10 was 0.5%greater than that of the small sowing machine 2B-2,the plant height and LAI were 0.4%and 0.7%lower,while the stem diameter and plant dry weight had basically the same performance.The results showed that the sowing depth exerted great effects on agronomic traits of maize plant,and the agronomic traits of maize with the sowing depth of 5 cm were much better than that with the sowing depth of 8 cm,while different sowing equipment had little effect on agronomic traits of mechanized sowing maize at the three-leaf stage.
