摘要

选择19种草本植物分别在江西省宁都县的花岗岩侵蚀区和德安县的第四纪红壤侵蚀区进行了3a的定位试验。通过对出苗率、成活率、平均分蘖数、覆盖度、地上部分浸水容重、根系鲜重、地上部分生物鲜重、有机质等指标进行观测

并采用层次分析法和模糊数学方法对试验品种进行综合评价

从中优选出百喜草和宽叶雀稗2种草在花岗岩侵蚀区和第四纪红壤侵蚀区都生长良好的草种。研究结果认为

糖蜜草、柱花草、棕叶狗尾草、鸡眼草、马塘草5种草本植物在花岗岩侵蚀区生长良好。画眉草、黑麦草、狗牙根、假俭草和苏丹草5种草本植物在第四纪红壤侵蚀区生长良好。

Abstract

19 kinds of grasses were selected to plant in the granite erosion area

Ningdu County and the quaternary red soil erosion area

De'an County

Jiangxi Province.In the three year field experiment

the indexes of rate of seedlings emergence

survival rate

average tiller number

vegetation coverage

fresh weight of root

upland part of grass's unit weight and biomass

and soil organic matter were investigated.The method of analytic hierarchy process(AHP) and fuzzy mathematics were used to evaluate the grasses.Results show that Palspalum notatum Flugge and Paspalum wettsteinit Hackel can grow well in the two test areas;Melinis minuciflora

Styiosanthes guianensis(Aubi) SW.

Setaria palmifolia.

Kummerowia striata(Thunb.)Schindl

and Digitaria sanguinalis can grow well in the granite erosion area;and Eragrostis pilosa

Lolium L.

Cynodon dactylon

Eremochloa ophiuroides

and Sorghum sudauense can grow well in the quaternary red soil erosion area.
