大葱在北方栽培普遍,产量高,品质好。我省历年从山东调进大葱投放市场。近年来,销售量大,不能满足市场需要。而就地生产,则由于未掌握其栽培技术,产量低,质量差。为此,我们进行了大葱高产栽培试验。供试品种为“梧桐葱”,在0.6亩地上,获得4,045斤的产量,折合亩产6,742斤,最大单株重达1.2斤,。现将大葱栽培技术总结如下。 Green onions are widely cultivated in the north with high yield and good quality. Shandong Province, transferred from the calendar year onions put on the market. In recent years, sales volume, can not meet the needs of the market. In situ production, the lack of control of their cultivation techniques, low yield, poor quality. To this end, we conducted a high-yielding green onion cultivation experiments. The tested varieties were “Indus onion”, yielding 4,045 catties on 0.6 acres of land, equivalent to 6,742 catties per mu and the largest single plant weighing 1.2 kilos. Now green onion cultivation techniques are summarized below.
