以18年生“兰州大接杏”为试材,研究比较了树行间自然生草和清耕(CK)2种不同的果园生草处理对果园土壤地温、土壤水分、土壤理化性状及杏园病虫害和杏果实品质、产量的影响。结果表明:高海拔冷凉干旱地区杏园生草可使林间温度比清耕园温度变幅小,升温慢,降温也慢,表层土壤温度的变幅比清耕地小;生草杏园果实品质明显提高,使主栽培品种“兰州大接杏”可溶性固形物含量提高0.7个百分点、平均单果重增加11.8g;同时杏园生草能减少病虫害发生,增加土壤有机质含量,提高土壤肥力和蓄水保墒能力。
Taking 18 years old “Lanzhou Daxing apricot ” as experimental materials, the effects of grass - planting on natural soil temperature, soil moisture and soil physical and chemical properties in orchard were compared and studied. Apricot garden pests and apricot fruit quality, yield impact. The results showed that: the fresh apricot of high altitude and cool grassland can make the forest temperature is less than Qinggongyuan temperature range, slow warming, slow cooling, surface soil temperature amplitude less clear land; The quality of main cultivars increased significantly by 0.7 percentage points, and the average fruit weight increased by 11.8 g. Meanwhile, the apricot orchard grass could reduce the occurrence of pests and diseases, increase the content of soil organic matter and increase the soil fertility And water storage capacity.
