摘  要:
通过杨树无性系扦插育苗试验,研究了地膜覆盖、保水剂对育苗地土壤物理性质、苗木生长的影响。结果表明,在降雨频繁的季节,不同保水措施都有提高苗木成活率、光合速率,促进苗木生长的作用;有降低土壤容重,增加土壤孔隙度,改善土壤物理性质的作用,其中黑膜覆盖效果最好,保水剂次之;黑膜覆盖有明显增加土温、保持土壤水分的作用,而保水剂无明显作用。

摘  要:
The experiment is conducted to evaluate the effects of different water-retaining measures on soil structure and populus seedlings growth. The results showed plastic film mulching and second aquasorb can elevate seedlings living rate and daily rhythm of photosynthesis rate, and increase the diameter and height of seedling. And the black plastic film mulching can increase the temperature of the soil and enhance soil moisture.
