- 摘要:
- 以杏园内间作的苜蓿为试材，研究刈割对杏树间作下杏树、苜蓿根系生物量与垂直分布、土壤有机质含量、土壤pH和电导率的影响。结果表明：杏树的侧根系在土壤垂直分布主要集中在土层20~60 cm处。苜蓿根系分布呈倒金子塔型，主要分布在0~40 cm以上土层。刈割显著地促进苜蓿根系生长，且随刈割次数的增加而增加；多次刈割促使苜蓿吸收根呈浅层化分布。刈割苜蓿可有效地增加表层土壤的有机质含量，但对土壤pH、电导率的影响不显著。因此，适宜地刈割不仅促进紫花苜蓿的根系生长，可以有效地改善杏树园土壤养分，但多次（不低于3次）刈割会增加苜蓿吸收根系，从而会增加与果树之间的养分竞争。
- Abstract:
- A plot test was studied that the effect of mowing was on the root biomass and root system distribution of alfalfa and apricot,soil organic matter content,pH and electrical conductivity in the apricot garden.The results showed that the lateral roots of apricot tree were mainly concentrated in soil layer 20-60 cm.The distribution of alfalfa roots was gold tower type,and alfalfa roots were mainly distributed in more than 0 to 40 cm.Mowing had significant effects on alfalfa underground biomass,and with the times increasing of mowing,and the more times of mowing made that the distribution of alfalfa absorbing root was shallow.The more times of mowing effectively increased organic matter contents of the upper soil,but the effect of moving was not significantly on soil pH and electrical conductivity in the apricot garden.Therefore,suitable times of moving not only promoted the growth of underground part of alfalfa,and also could effectively improved the apricot garden soil nutrient status,but more times (more than 3 times) of moving increased more competition for nutrients between fruit trees roots and alfalfa roots.
