摘要
为了研究防雹网对苹果树的生长、区域小气候、土壤的温度和水分变化及苹果产量和品质的影响情况,对搭建了防雹网的苹果园内各生态因子指标进行了试验研究与测定分析。结果表明:搭建防雹网可有效提高苹果园内空气的相对湿度,并防止相对湿度的大幅度变化;防雹网能明显降低苹果园的温度,可避免苹果果面日灼现象的发生,提高苹果的产量和质量;防雹网减缓了苹果园内昼夜温度的变化速率,促进了土壤中水气的上下移动,提高了果树根系的吸收能力和吸收速度;防雹网减少了地面蒸发,提高了果树对土壤水分的利用率;防雹网还可明显提高苹果产量与平均单果质量,而对苹果的果肉硬度、可溶性固形物含量等品质指标的影响却不太明显。
In order to study the effects of anti-hail net on tree growth,yield and quality of apple,regional microclimate,temperature and water content in soil,the ecological factors in apple orchard with anti-hail net were determined and analyzed.The results showed that anti-hail net could effectively improve the relative humidity in orchard,and remain stable relative humidity.The anti-hail net could reduced temperature obviously in orchard,avoid occuring burning phenomenon on the surface of apple,and improve quality and yield of apple.The anti-hail net could slow down the speed of temperature changing in the day and night of orchard,promote moving of the moisture in soil,and improve absorbency and absorption rate of tree root.The anti-hail net could reduce the surface evaporation,and improve the soil water utilization of fruit trees.The anti-hail net could obviously improve yield and average mass per fruit,and the effects on pulp hardness and soluble solids content were not obvious.
