冬、春季节果树常遭受低温冻害,轻者易使花芽冻伤,枝条抽干,致使果树产量低、品质差、效益低,重者可造成整株死亡。现根据各地经验,介绍10种行之有效的御寒防冻方法: 1.果园覆草。可覆盖谷壳、秸草、树叶等,即可保墒,又可阻隔冷气侵袭,对保持和提高地温、防止果树冻害效果显著。 2.地膜覆盖。在果树周围1米直径范围内覆盖厚0.05毫米的地膜,既能保墒、防止热量散失,又能保温防冻。覆膜应在冬灌和中耕培土以后进行。
In winter and spring, fruit trees are often subjected to low temperature frost damage. Light ones tend to frostbite flower buds and drained branches. As a result, the yield of fruit trees is low, their quality is poor, and their benefits are low. Now based on local experience, introduced 10 kinds of effective anti-freezing method: 1. Orchard mulch. Can cover the chaff, straw, leaves, etc., can protect soil moisture, but also blocking the invasion of air-conditioning, to maintain and improve ground temperature, fruit trees to prevent freezing effect is remarkable. Film mulching In the fruit trees around the diameter of 1 meter cover 0.05 mm thick plastic film, both moisture, prevent heat loss, but also insulation freeze. Coating should be carried out after winter irrigation and cultivation of soil.
