| 中文摘要: |
| 通过设置锯末、白色园艺地布+锯末、黑色园艺地布+锯末、白色园艺地布和黑色园艺地布5种土壤覆盖方式，以不覆盖为对照，利用土壤温度监测记录仪对越橘生长期（5月-10月）不同深度土层土壤温度进行连续监测，分析不同覆盖方式对越橘园10 cm、20 cm和30 cm土层土壤温度的影响。结果表明，不同覆盖方式在整个越橘生长期内均有调节土壤温度的效果，不同覆盖方式对不同深度土层土壤日平均温度的变化趋势总体相似。锯末覆盖处理的土壤温度在越橘生长前期（5月-8月）低于对照，在越橘生长后期（9月-10月）高于对照，且土壤温度日变幅显著低于对照，说明锯末覆盖处理的保温效果最好；黑色园艺地布覆盖处理的保温效果次之，且黑色园艺地布和黑色园艺地布+锯末覆盖处理在整个越橘生长期内的土壤温度均高于对照，辽宁地区春季和秋季气温较低，适当提高土壤温度有利于越橘根系生长和树体发育。而白色园艺地布覆盖处理和白色园艺地布+锯末覆盖处理的土壤温度均低于对照，且白色园艺地布覆盖处理的保温效果较差。因此，辽宁地区越橘园推荐采用黑色园艺地布并添加锯末的土壤覆盖方式具有良好的可行性和实用性。 |

| Analysis of effects of different mulch methods on soil temperature in blueberry orchard. The treatments were consisted of sawdust, white horticultural fabric+ sawdust, black horticultural fabric+ sawdust, white horticultural fabric, black horticultural fabric, and bare soil as control. The soil temperature monitoring recorder was used to continuously monitor soil temperature at different depths during the growing period of blueberry (from May to October). The results showed that, different mulch methods had the effect of regulating soil temperature during the whole growing period of blueberry. The trend of daily average temperature of soil at different depths was similar under different mulch methods. Compared with the control, the soil temperature during early blueberry growing period (May-August) was lower, and the soil temperature during later blueberry growing period (September-October) was higher. The soil temperature daily amplitudes were significantly lower than the control. It shows that the heat preservation effect of sawdust covering treatment is the best. And black horticultural fabric possessed better thermal insulation effect. The soil temperature of black horticultural fabric+ sawdust and black horticultural fabric was higher than control. The temperature in spring and autumn is lower in Liaoning province, and increasing soil temperature properly is beneficial to the growth of root system and tree body of blueberry. The heat preservation effect of white horticultural fabric is the worst. The soil temperature of white horticultural fabric+ sawdust and white horticultural fabric was lower than control. Therefore, it is feasible and practical to use black horticultural fabric+ sawdust as the soil mulch in Liaoning blueberry orchard. |
