摘要

有机肥对草地植物区系组成有影响。用粪肥施肥有利于草原的植物多样性。本研究旨在探讨不同时间间隔、少量地膜和有机肥对阿普塞尼山地毛毡草-红羊茅草地类型干物质产量和植物多样性的影响。7棵treatmentsÂ (controlÂ(刈1棵/年);覆盖物1 /年;覆盖1吨/公顷/年+粪肥5吨/公顷/年;覆膜1次/年+ 5吨/公顷粪肥/2年;覆盖1次/年+ 10吨/公顷粪肥/2年;覆盖1次/年+ 10吨/公顷粪肥/3年;弃置)Â实验评价。少量施用有机肥可以维持阿普塞尼山区少营养化草地的植物区系多样性。

Research on the Influence of Organic Fertilizing and Mulching on Productivity and Phytodiversity on Oligotrophic Grasslands

Organic fertilizers have an influence on the floristic composition of grasslands. Fertilizing with manure favours the phytodiversity of grasslands. The objective of the study was to follow the influence of mulching and organic fertilizing in small quantities and at various time intervals upon dry matter yield and phytodiversity of Agrostis capillaris L. - Festuca rubra L. grassland type in the Apuseni Mountains. Seven treatmentsÂ ( controlÂ ( mowed 1/year ) ; mulch 1/year; mulch 1/year + 5 t/ha manure /year; mulch 1/year + 5 t/ha manure/2 years; mulch 1/year + 10 t/ha manure/2 years; mulch 1/year + 10 t/ha manure/3 years; abandonment )Â were evaluated experimentally. Organic fertilizing in low quantities could be a way to maintain the floristic diversity of oligotrophic grasslands in Apuseni Mountains.
