不同播期及密度对大蒜产量构成的影响

Effect of the Different Sowing-time and Density on Garlic Yield

为探明不同的栽培处理方式对大蒜产量构成的影响,以当阳主栽品种二水早为试材,采用不同播期及密度处理,对大蒜的出苗率、田间长势、青蒜产量、蒜薹产量及蒜头产量进行观察比较。结果表明,二水早在当阳地区播种期以8月10日左右为宜,栽培密度采用166.5万株·hm-2,青蒜产量可达到52474.2 kg·hm-2,蒜薹产量达到34 433.9 kg·hm-2,蒜头产量达到20 565.96 kg·hm-2。

The experiment was designed with two factors of sowing time and density for different cultivation approach in garlic. According to the data obtained, the appropriate sowing time of garlic was about 10 in Dangyang,area. Under the Planting density of 166.5×10^4hm^-2, the leaf garlic yield of 52 474.2 kg·hm^-2 stem garlic yield of 34 433.9 kg·hm^-2 and garlic yield of 20 565.96 kg·hm^-2 could be obtained.
