在一些偏远的农村,一时不能建起温室或大棚,但可在庭院扣小拱棚栽培韭菜,这不仅成本低,而且也能获得较好的经济效益。韭菜可选用汉中冬韭品种,4月中下旬播种。播前翻地1锹深,耙细搂平。播种幅宽13厘米,两幅间空20厘米。每100平方米播种量1—1.25公斤。播后至10月间,要及时除草,防治地蛆可喷600—800倍敌百虫药液。7月份气温高韭菜生长过旺时,从梢部割去1/3,防止烂韭菜。 In some remote rural areas, we can not build greenhouses or greenhouses for a time, but we can plant leeks in the small shed in the courtyard, which not only has low cost but also obtains good economic benefits. Chinese chives can be used in winter Leek species, sown in late April. Before sowing a deep shovel, rake thin hug flat. Sowing width of 13 cm, two empty 20 cm. 1-1.25 kg of seeding per 100 m2.
