文冠果根系分布特征及生长适应性

通过对文冠果根系分布及生长调查分析表明:文冠果根深、根系发达、根幅大,5个月的幼苗主根深度可达50 cm,根幅可达28 cm,主根明显垂直向下深入土壤下层,能够吸收土壤深层水分,在极端干旱条件下能够生长.文冠果根系保水力强,抗干旱贫瘠,但不耐水涝,低温土壤中生长缓慢.在积水土壤中栽植时,应创造良好的排水条件.

Root Distribution Characteristic and Growth Adaptability of Xanthoceras sorbrflra

Based on investigation and analysis of root distribution and growth of Xanthoceras sorbrflra,the results showed: root of Xanthoceras sorbrflra was deep,root system was developed,root range was big,main root depth of 5-months seedling can reach 50 cm,and root range can reach 28 cm,obviously main root vertical down into the soil below,it can absorb moisture in deep soil and can grow in extreme drought conditions.Water retention of root system of Xanthoceras sorbrflra was strong,drought-resistant was poor,but it was not able to bear or endure water logging,growth of root system was slow in the soil at low temperature.We should create a good drainage condition when planting it in soil land with hydrops.
