三峡库区沿江退耕还林地种草效果初探

THE EFFECTS OF FORAGE PLANTING IN THE REGION ALONG THE THREE GORGES OF THE CHANGJIANG RIVER WHERE RETURNING FARMLAND TO FORESTS IS PRACTICED

在农区退耕早熟梨地种植豆科、禾本科牧草,通过测定它们的盖度变化、产草量和越夏率,比较分析了果园适宜种植牧草品种及应注意的问题,并讨论了重庆低海拔沿江农区发展草业生产的前景。

In the experiment, legume and grass forages were grown in the early maturing pear orchards where farmland had been returned to forests. Their coverage degree, forage production and over-summering rate were recorded and compared so as to select grass or legume varieties adaptable to the conditions of these orchards. The problems worth attention and the perspective of forage production development in low altitude farming area along the Changjiang River in Chongqing were discussed.
