黑麦草─白三叶放牧地第一性生产力研究

Study on the Primary Productivity of Ryegrass and White Clover Pasture.

基于对南方草地放牧条件下草地季节调查，对草地地上生物量、地下生物量、枯死体、家畜移出量、第一性生产力以及牧草生长速率与气候因子的关系进行了研究。

Based on the field investigation of ryegrass and white clover pasture,above-ground biomass, under-grotind biomass,dead matter,output,return,primary productivity and the relation between grass growth rates and climates were studied.
