芦笋为深根性宿根植物,根的纵深可达3米,侧向分布半径一米左右,植株分布直径能达3米以上。一经定植,要延续收获10—15年,乃至20年。为便于每年的退箱施肥、垒厢采笋等管理作业,奠定持续丰产基础,育苗与移栽是整个高产栽培中的关键环节。培育壮苗栽培芦笋可以直播,也可以育苗移栽。由于育苗移栽有用种少、易于苗期管理、苗株健壮、土地利用经济等许多优点,故生产上普遍采用。 (一)播种时间:芦笋在地温10℃以上即可育苗。一般采
Asparagus deep root perennial plants, roots up to 3 meters in depth, the lateral distribution of a radius of about 1 meter, the distribution of plants can reach more than 3 meters in diameter. Once colonized, to continue the harvest of 10-15 years, and even 20 years. In order to facilitate the annual back-box fertilization, crop sticking shoots and other management operations, laying a foundation for sustained high yield, nursery and transplanting is the key to the high yielding cultivation. Cultivation of strong seedlings can be broadcast asparagus, transplanting seedlings can also be. As seedling transplanting useful species, easy to seedling management, seedling robust, land-use economy and many other advantages, it is widely used in production. (A) sowing time: Asparagus in the ground temperature above 10 ℃ can be nursery. General mining
