核桃霜冻防御措施研究

Study on Measures for Defending Frost of Walnut

采取化学防治、物理防治、应用抗冻品种等措施防御核桃霜冻,并对防御效果进行了分析。结果表明,化学防治效果不明显,薰烟防冻有一定的耐受度。最后提出核桃霜冻的应对措施,主要在于建园时园址的选择和抗冻品种的选择。

The chemical control, physcal control and application of antifreeze varieties were used to defend the frost of walnut, and the defensive effects were analyzed. The results showed that the effect of chemical control was no obvious, and smoking method had certain limitation in temperature. Finally, the measures for defending frost of walnut were put forward, and the key was site selection of walnut orchard and application of antifreeze varieties.
