不同前茬作物与种植密度对大蒜农艺性状的影响

为研究不同前茬作物和种植密度对大蒜生长发育的影响，通过设定大豆茬(A1)、谷子茬(A2)和不同密度(M1、M2)两因素试验，测定不同处理的大蒜农艺性状指标和产量。试验结果表明，大蒜的农艺性状指标A1处理高于A2处理，M2处理高于M1处理，处理间产量没有显著差异。在生产中可以通过优化前茬作物和种植密度来提升大蒜商品性。

Effects of Different Previous Crops and Planting Densities on Agronomic Characters of Garlic

To study the effects of different previous crops and planting densities on garlic growth and development, a two-factor test was set up in this study, including previous crops of soybean (A1) and millet (A2), and planting densities of M1 and M2, then the agronomic character indexes and yield of garlic under different treatments were determined. The results showed that the agronomic character indexes of garlic under A1 treatment were higher than those under A2 treatment with very significant difference, and the indexes under M2 treatment were higher than those under M1 treatment with significant difference. There was no significant difference of yield among the treatments. So, optimizing previous crops and planting density in garlic production can improve its marketability.
