Comparative Analysis of Conservation Tillage Mode in Fumeng County
In 2022,a comparative experiment of different corn planting modes were carried out in the county-level conservation tillage base in Fumeng County,including the full-cover straw returning to the field with no tillage and two-to-empty cultivation mode(no tillage),the full-cover corn straw returning to the field with less tillage and two-to-empty cultivation mode(less tillage),the corn straw crushing and returning to the field and the traditional tillage mode.The results showed that the average yield of corn under no-tillage treatment was 860.13 kg/667 m2,which was 13.75％ higher than that under traditional planting(adjacent plots in the project area),and the soil bulk density was increased between 0 and 20 cm after straw mulching,the soil moisture content was significantly increased,and the soil temperature decreased without affecting the timely sowing.It is suggested that the corn planting in this area should be dominated by straw full cover and no-till planting.
