摘要
本文主要研究了甘肃张掖硫酸盐土壤生长1～3年碱茅草的株高、分蘖数、产量的年度间变化。并依此建立了株高和分蘖数对产量构成的预测模型,为硫酸盐土壤地区建立人工碱茅草地提供了参考依据。
The parer has mainly been dealt with factor analysis by variations between years on culm heights, number of tillerings and yields of Puccinellia chinampoensis Ohwi when Plantion for one to three years from 1985 to 1987 in sulphate soils of Zhangye district, Gansu, And in accordance with this calculation statistically, a prediction modelling was constitured with regard to such parameters as culm height and number of tillering versus yield, thus providing referential basis for establishing the Puccinellia cultivative grassland of sulphate soils.
