不同栽培方式对韭菜生产的影响

在温室内采用3种不同的无土栽培方式和常规土壤栽培方式进行了津引一号韭菜的种植试验。结果表明，韭菜3种无土栽培方式的株高和第1次收获时的产量均极显著 地高于土壤栽培，其3次收获累计产量均高于土壤栽培，无土栽培浇施1号营养液处理、无土栽培浇施Ⅱ号营养液处理和有机生态型无土栽培的3次收获累计产量比土壤栽培分别提高了61％、49％和35％，3种无土栽培方式的韭菜产品硝酸盐含量均低于土壤栽培，其中有机生态型无栽培和硝酸盐含量最低。

Effect of Different Culture Ways on Chinese Chive Production

The plants being in the second growing season of C hinesechive(Allium tuberosum Rottl.ex Spr.) ‘Jinyin No.1' were cultured by different culture ways in greenhouse in winter.The results indicated that the t otal yield for three times harvest(TY),the first harvest yield, and the plant he ight of three ways of soilless culture were all significantly higher than that o f soil culture of Chinese chive.Comparing with the soil culture,TY of soilless cu lture with No.Ⅰ nutrient solution,soilless culture with No.Ⅱ nutrient solution , eco-organic type soilless culture increased by 61%,49% and 35%.The nitrate cont ent in Chinese chive of three ways of soilless culture was lower than that of so il culture.Of all the treatment,the nitrate content of eco-organic type soilles s culture was the lowest.
