芦笋是雌雄异株作物,由于雄株收获早、产量高(比雌株高3成左右),嫩茎粗度适于食用,并且不会落下种子而形成杂草化的实生苗,故栽培雄株比雌株对农业生产有利。但目前只能根据花器形态鉴定性别,而开花需要2～3年,因此一般很难在一年生苗定植时只选雄株来定植。这就需要尽早确立早
Asparagus is a dioecious crop, as the male plant early harvest, high yield (about 3 percent higher than the female plant), tender stem diameter suitable for consumption, and will not fall seeds to form weed seedlings, so the cultivation of male Strain is beneficial to agricultural production than female plant. However, at present, gender can only be identified according to the shape of the flower, and flowering requires 2 to 3 years. Therefore, it is generally difficult to select only the male plants for colonization when the annual seedling is planted. This needs to be established early
