在乌鲁木齐以白皮洋葱为材料,利用近苔仔魿茎连续採种。多次结实的植株抽苔开花较早,花茎稍低,花球直径也稍小。在不移栽近苔仔魿茎的情况下,种子的收量逐年降低,和普通的种子比较,多次结实种子的千粒重轻些,但是第三次结实的种子比第二次结实的种子重些,在田间直播的试验中,由多次结实种子长成的洋葱的产量无显著差异,魿茎的汁液浓度偏高。
In Urumqi to white onions for the material, the use of near moss Tsai stem continuous seed collection. Multiple strong plants bolting flowering earlier, slightly lower stems, flower balls diameter is also smaller. In the case of not transplanting near the moss and stems and stems, the yield of seeds decreased year by year, compared with the normal seed, multiple seed thousand seed weight lighter, but the third seed is stronger than the second solid seed weight In the live field experiment, there was no significant difference in the yield of onions grown from multiple strong seeds, and the stem juice had a high concentration.
