近年来,莱阳市各地针对外商对菠菜的需求量大和菠菜喜低温、生长周期短的特点,抓住大田作物收后、播前的低温季节,插种两茬秋菠菜和一茬越冬菠菜,创出了“三茬菠菜一季玉米”的高产高效栽培模式,使菠菜的种植面积大增,已成为大宗出口创汇的蔬菜品种之一。1998年莱阳市照旺庄镇西昌山村闫振基户种植的三茬菠菜,平均亩产鲜菜8500kg,玉米675kg,年平均亩收入8650元;该村闫乃军户种植的12亩菠菜,平均亩产鲜菜7800kg,玉米650kg,年平均亩收入8350元。其栽培技术如下。一、合理安排播期、播量 8月中旬,春播玉米收后,立即耕翻地,抢种第一茬秋菠菜。此时播种气温高,菠菜出苗率低,也常有
In recent years, Laiyang City, in response to foreign large demand for spinach and spinach hi cold, short growth cycle characteristics, to seize the field crop harvest, pre-sowing low-temperature seasons, planting two crop autumn spinach and a stubble wintering spinach Out of the “three crop of spinach season ” high yield and efficient cultivation mode, so spinach planting area greatly increased, has become one of the major export varieties of vegetables.
