以河南中牟蒜区常年主栽品种为试材,按照随机区组设计,在壤土地栽种不同换种年限、不同土质来源的异地蒜种,研究异地换种,特别是换种年限和土质来源对大蒜生长和产量的影响,旨在为大蒜异地换种提供科学依据和具体指导。结果表明:不同土质来源的蒜种是影响大蒜生长和产量的关键因素;换种1a、来自粘土的蒜种处理(T4)表现最好,蒜薹和蒜头增产幅度分别达61.01%和22.85%;从大蒜植株生长势、蒜薹单重、蒜头单重、蒜头横径和大蒜产量上分析可知,大蒜异地换种以每3a换种1次为宜,粘土来源的蒜种优于砂土来源的蒜种,显著优于壤土来源的当地蒜种。 Taking perennial cultivars from Zhongmiou garlic area in Henan Province as test materials, different types of garlic cultivars with different years and sources of soil were planted on loam soil according to randomized block design to study the effects of different soil types, Garlic growth and yield effects, designed to provide alternative scientific basis for garlic and specific guidance. The results showed that: Garlic from different soil sources was the key factor affecting the growth and yield of garlic. For variety 1a, garlic from the clay had the best performance (T4), the yield of garlic sprouts and garlic reached 61.01% and 22.85% respectively; Garlic plant growth potential, garlic sprouts single weight, garlic single weight, garlic diameter and garlic yield analysis shows that garlic in different places to change every 3 to 3 times is appropriate, the clay source of garlic is better than the sand source of garlic , Significantly better than the local garlic origin of loamy soil.
