1适时下种生姜应适期播种,不可过早或过晚。若播种太早,地温低,热量不足,播后迟迟不能出苗,极易导致烂种或死苗;播种过晚,则出苗迟,从而缩短了生长期,造成减产。我市沿海平原生姜播种期一般在春分~清明,海拔500m以上的山区为清明~谷雨。如采用大棚等设施栽培,可适当提早播种时间,以延长生长期或提早上市,从而获得更高产量和种植效益。 A timely manner under the kind of ginger should be planted properly, not too early or too late. If sowing too early, low ground temperature, lack of heat, after sowing delay can not emerge easily lead to rotten or dead seedlings; sowing too late, the emergence of late, thus shortening the growth period, resulting in reduced production. Coastal plain ginger sowing season in general vernal ~ Qingming, 500m above sea level for the Qingming ~ Valley rain. Such as the use of greenhouses and other facilities cultivation, sowing time may be appropriate to extend the growth period or early market, resulting in higher yield and planting benefits.
