研究结果表明，不同瓣重、不同播期及不同品种大小不同的天蒜对独头蒜形成都有一定的影响种瓣的重量降至１ ｇ以下能促进独头蒜的形成；正常大小的种瓣在中原地区播期推迟至１１ 月１５ 日后也可以导致独头蒜的形成；利用小粒天蒜（ 气生鳞茎） 适时播种是获得独头蒜的一种经济有效方法
The results showed that garlic with different petals weight, different sowing dates and different varieties of different sizes had a certain influence on the formation of single head garlic. The weight of the petals reduced below 1 g can promote the formation of single head garlic; the normal size Seed petals in the Central Plains delayed sowing to November 15 can also lead to the formation of single-headed garlic; the use of small-grained garlic days (gas bulbs) timely sowing is a unique and effective way to obtain garlic
