由于加利福尼亚州南部沙漠和沿海地区的笋农希望密植,因此,常采用直播法建立芦笋园.土地准备:很多种植者象种其它中耕作物那样把芦笋种子直播在凸起的畦或平的地面上.但最好直播在专门预先作好的种植沟内,这样在以后的年份有充足的土壤可对植株培土并保证根颈埋于土表以下.通常采用的是平底沟间距5英尺,中心比原来的地面深5—7英寸.最初的沟用双壁犁开成,用装在橇上的畦成形器整畦,畦成形器后通常安装有精确的种植机,以便使畦的植距和种植作业操作一次完成.整好的畦在行间需有一平而坚实的埂以便于装备在田间的运行.
The asparagus garden is often established by direct seeding due to the close planting of shooters in the deserts and coastal areas of southern California.
