韭菜是一种多年生宿根蔬菜,每当秋季转冷后,叶片枯萎,其养分贮藏于根茎中.冬季温室韭菜的生长,主要靠根茎中所贮藏的养分.因此,进行温室韭菜生产,必须培育壮苗壮根.我省韭菜育苗可在3月下旬播种.播前,亩施优质农家肥以及腐熟马粪(1:1)1万斤以上,并每亩增施磷肥和三料肥30～40斤.深翻整地后,做1米宽、6～7米长的畦,按20厘米行距开5厘米深的沟,在沟内条播,播幅6～10厘米,覆土1.5厘米厚.如土壤干旱应及时浇水,保持畦面湿润.每亩苗地用种15～20斤,可定植2亩温室生产田.另外,也可在扣温室的地方春季直播,培养一年韭根就地扣棚.
Leek is a perennial perennial vegetables, each turn cold after the fall, the leaves withered, its nutrients stored in the rhizomes.Chicken in the greenhouse growth of leeks, mainly by the rhizomes stored nutrients.Therefore, the greenhouse leek production, we must cultivate strong Planting strong roots. Leek nursery in our province can be sown in late March before sowing, Mushi high-quality farm manure and maturity of manure (1: 1) 1 kg and above, and the increase of phosphate and fertilizer per acre 30 to 40 Kg deep after the turn, do 1 meter wide, 6 to 7 meters long 畦, according to 20 cm line spacing 5 cm deep groove, in the trench, sowing 6 to 10 cm, 1.5 cm thick soil cover, such as soil Drought should be timely watering, keep wet noodles.Use 15 ~ 20 kg per acre seedlings, can be planted 2 acres of greenhouses production field.In addition, the spring can be broadcast in the greenhouse where the buckle, cultivate leek root local buckle shed.
