Abstract:A field experiment was conducted to study the effects of different strength of compaction(250, 450, 650g/cm2), sowing depth(3, 5, 7 cm), as well as the ridging period on the emergence rate of maize under the condition of entire returning of maize straw after smashed. The results showed that the ridging period had little impact on the emergence rate of maize. The emergence rate was extremely significant affected by strength of compaction(P<0.01). The emergence rate of maize was affected significantly by the sowing depth(P<0.05). With the increase of the compaction strength, emergence rate of maize increased from 80.6% to 93.5%. The emergence rate of maizeat 5 cm was significantly higher than that of maize at 3 cm and 7 cm. The emergence rate of maize was extremely significant affected by interaction of sowing depth and strengthen of compaction. The highest emergence rate of maize was achieved 96.5% when the sowing depth was 5 cm and the strength of compaction was 650 g/cm2, which was the best sowing treatment under the test conditions.
