大蒜是用鳞茎作为播种材料的无性繁殖植物,繁殖系数低,用种量大。尤其是实行优质优价政策后,由于蒜头大小的价格差异大,蒜农偏重于当年种蒜收入,往往把大的蒜头出售,小的留种,致使种性退化,产量不高。为了摸索种瓣大小对大蒜生长发育及产量的影响,前几年,我们在娄塘、唐行乡进行了该项研究,并对其产量性状作了进一步的观察。 Garlic is a vegetative propagation plant that uses bulbs as sowing material, has low propagation coefficient, and is used in large quantities. In particular, the implementation of high-quality price policy, due to the size of the garlic big differences in the price of garlic, garlic farmers tend to focus on the year when the income of garlic, tend to sell large garlic, leaving a small seed, resulting in degenerative species, yield is not high. In order to explore the impact of seed size on the growth and yield of garlic, a few years ago, we carried out the study in Lou Tang and Tanghang Township, and further observed its yield traits.
