鄂北双季花生高产栽培技术初探

Techniques for high yielding cultivation of double cropping of peanut in north Hubei Province

一年内连续两次种植花生是鄂北地区花生种植方式的一项重要改革。通过三年的试验，研究了在鄂北条件下双季连作花生栽培的良种选用、播种期、种植密度和管理措施等关键栽培技术，结果表明以早熟高产的中花４号等品种，第一季地膜覆盖于３月下旬播种，第二季在８月初露地播种并适当增加种植密度，能够获得双季花生７５００ｋｇ／ｈｍ２以上的产量。

Annually double cropping of peanut is an important change of peanut cultivation in the north part of Hubei Province. In this study, suitable peanut variety, sowing date, plant density and field management practices in this cropping system were investigated for three years. Peanut cultivars including Zhonghua No.4 with early maturity and high yield potential were desirable. The first crop should be sowed in late March by plastic mulch cultivation and the second crop sowed in early August with a little higher plant density. The yield of the double cropping could be more than 7500kg/hm 2.
