外界温度降至-7℃前,要及时对草莓盖防寒保暖物,使其在田间安全越冬。只有在良好的保暖防寒条件下,草霉叶片才能保持绿色,早春才生长快、成熟早、产量高。 防寒保暖的方法主要是设风障、盖草、埋土及压厩肥等。在密植的草莓园中,可每隔10—15米设风障一道,用玉米秸做风障材料,障高2.5米。在
Outside the temperature dropped to -7 ℃ before, we should promptly cover the strawberries cold warmth, making it safe in the field wintering. Only in good warm and cold conditions, grass mold leaves to maintain green, early spring before growing fast, mature early, high yield.
