异地换种对大蒜生长和产量的影响

Effect of the Foreign Location Seed Change on the Growth and Yield of Garlic

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 the local main garlic eultivars from Zhongmu of Henan as material,according to the randomized block design,effect of the foreign location seed change on the growth and yield of garlic were studied by planting the seed-bulb of different changing species periods and different soil in loam soil, The results showed that, the garlic of the changing species one year,coming from clays treatment （T4） was the best,its garlic bulb and garlic bolt could increase the yield by 61.01% and 22. 85 %. With analyzing the growth vigor of garlic, single garlic bolt weight, single garlic bulb weight,garlic bulb transverse diameter and the yield of garlic, one time every three years was the suitable treatment for changing species,the seed-bulb from clays better than the seed from sand soil, significantly greater than the loam soil,it showed that the seed-bulb from different ,soil sources was the key factors influencing on the yield and growth of garlic.
