不同机型和播种参数对大蒜播种效果的影响
Effect of Planter and Planting Parameters on Garlic Planting Quality
摘要
Abstract
To improve the quality of mechanical planting of garlic,this study analyzed the effects of factors such as the depth of the seed layer in seed box,seeding rate,crop rotation pattern(garlic-corn,garlic-rice),uniformity of garlic clove size,operating speed,and planting depth on the mechanical planting quality.The experimental results indicate that at 1/4,1/2,and full of seed box,the minimum miss-seeding rate corresponds to machine B,A,and B,the value were 7.2%,7.7%,and 8.3% .The miss-seeding rates of machine A and C increase with seeding rate,and the upright planting rate reaches the maximum value of 94% when the seeding rate was 375 thousand hills per hectare.As seeding rate increases,the proportion of garlic diameter greater than or equal to 5cm decreases for both machines.Under the two crop rotation pattern of corn and rice,there was no significant difference in upright planting rate for machine A;however,the miss-seeding rate and reseeding rate of machine A were 1.0% and 1.1% less than those of machine C respectively.The miss-seeding rates of machine A and C show a trend of increase and then decrease with the increase of garlic weight,the average miss-seeding rates were 4.4% and 3.2% respectively.With the increase of operating speed,the miss-seeding rate shows an upward trend while the reseeding rate shows a downward trend.The average miss-seeding rates for machine A,B,and C at different speeds are 9.4%,7.6% and 8.8%,and the average reseeding rates were 5.9%,8.3%,and 6.4% .The suitable operating speed is 0.3 m·s-1.The increase of planting depth helps to improve the upright planting rate,the average miss-seeding rates were 8.4%,8.1%,and 8.1% separately for machine A,B and C at different planting depths,the average reseeding rates were 6.6%,9.2%,and 7% respectively.The three seeders show an increasing trend in yield with the increase in planting depth.These research can provide reference for the selection of garlic seeders.关键词
