摘要
果园生草能够抑制土壤风蚀尘、减轻大气污染,增加土壤团聚体数量、提高土壤固碳潜力、增强土壤碳汇功能,缓解大气温室效应,丰富果园空间层次、调节果园生态小气候,减轻果园立体污染、改善果树生长环境,对河北省生态环境保护至关重要。针对河北省寒暑悬殊、气象灾害频繁,水资源短缺,土壤有机质含量低、贫氮少磷,果树病虫害严重、果园作业程序多等问题,探讨了河北省发展果园生草时草种选择应遵循的原则,明确了河北省果园生草应选择抗逆性强、耐践踏、根系分布浅、能够改善果园生态系统、适宜秋播、落籽自生能力强、符合不同利用目的的草种,可为改善河北省果园生态环境、促进果品绿色生产、实现乡村振兴提供参考。
Growing grass in orchard plays a vital role in the protection of ecological environment in Hebei Province as it can reduce air pollution by inhibiting wind-blown dust,increase soil aggregates and carbon sequestration potential,enhance soil carbon sink function,alleviate the greenhouse effect,enrich the spatial level of orchard,adjust the ecological microclimate,reduce the three-dimensional pollution,and improve the growth environment of fruit trees.In view of the problems of the great disparity of air temperatures between winter and summer,the frequent meteorological disasters,the shortage of water resources,the low contents of soil organic matter,nitrogen and phosphorus,the serious diseases and insect pests of fruit trees,and the complicated operation procedure in orchard in Hebei Province,we analyzed the principles to be followed in the species selection of orchard grass in Hebei Province and cleared that the grass species with strong resistance to stress,tolerance to trampling and shallow root distribution,which could improve the orchard ecosystem,was suitable for autumn sowing with strong viability of dropped seeds,and could meet different utilization purposes should be selected.This paper could provide references for improving orchard’s ecological environment,promoting fruit’s green production and revitalizing the countryside in Hebei Province.
