摘　　要：通过对洛川苹果花期防冻试验效果进行综合分析,提出了黄土高原地区在辐射降温天气影响下经济有效的防霜措施。结果表明,喷施防冻剂和烟雾防霜使得苹果坐果率提高了一倍,效果明显,成本低,是值得全面推广的措施。空气扰动防霜,在安装风机前应对当地空气温度进行监测,确保气象条件适宜。喷水防霜和热风机防霜,需要电力保障和充足的水储备,在黄土高原地区不适宜大面积推广,在经济价值高的小地块可适当应用。Based on the comprehensive analysis on the anti-freezing test effect during Luochuan apple flowering period,a cost-effective anti-frosting measure under the influence of radiation cooling weather in the Loess Plateau was proposed.The conclusions show that spraying antifreeze and smoke anti-frost make the fruit setting rate doubled,the effect is very obvious,and the cost is low,which is a measure worthy of comprehensive promotion.The air is disturbed and frostproof.Before installing the fan,the local air temperature should be observed to ensure the meteorological conditions are appropriate.Water spray and frost protection and hot air blower anti-frost need electric power guarantee and sufficient water reserve,which is not suitable for large-scale promotion in the Loess Plateau region,and can be suitably applied in small plots with high economic value.
