摘要
核桃复合栽培区一般能降低风速21％～52％;空气相对湿度白天平均增加了9.7％,夜晚平均增加4.3％;地温从5～8月低温较对照地偏低,落叶前核桃复合栽培区的气温和地温比对照地均有增加;对光合作用影响最大的强度是2～3万Lux.
Agro -- forestry conception-based walnut plantation can reduce the wind velocity by 21- 52%, increase the relative humidity by 9.7% in the day on average and 4.3% during the night. The ground temperature from May to August is relatively low but increase before foliage. The plantation＇s photosynthesis is affected by 20,000-- 30,000 lux.
