摘要
针对大蒜不同类型播种机作业经济性差异不明确现状,开展了不同机型的播种经济性试验。以人工播种为对照,通过对正芽机播和非正芽机播(摆种机播)在平作模式下的生长和收益情况进行对比,分析不同面积下的经济性。结果表明,机播生产成本随播种面积和机具数量的变化而变化,在种植面积小和种植年限短的条件下,以8行摆种机播为最优。随着种植面积和年限的增加,机械播种效益要高于人工播种,呈现出正芽机播>非正芽机播>人工播种,且面积越大效益越明显。5年周期内,非正芽机播较人工播种效益增加,最高增效10.1%,最低增效4.1%,3种播种方式相对效益在种植面积较小时,相对效益相差大,随着种植面积的增加,趋势变小。
In view of the unclear economic effects of different types of garlic planter,the economic experiments of different types of garlic planters were carried out.Compared with artificial seeding(control),the growth and output value of positive bud machine seeding,non-positive bud machine seeding(random machine seeding)under flat mode were compared,and the economic benefits under different planting areas were analyzed.The results showed that the production cost of mechanical seeding varied with the area and the number of machines.Under the condition of small planting area and short planting years,8-row random planter was the optimal seeding method.With the increase of planting area and years,the benefit of mechanical seeding was higher than that of artificial seeding,the law of the benefits was 12-row positive bud planter>8-row random planter>artificial seeding,and the larger area,the more obvious.In the 5-years cycle,the benefits of 8-row planter seeding were increased compared with artificial seeding.The highest efficiency was 10.1%,and the lowest was 4.1%.The relative benefits of the three seeding methods varied greatly when the planting area was small,and the trend becomes smaller with the increase of planting area.
