北京房山采石场渣土基质对高羊茅生长的影响
Effect of Quarry Waste Matrix on Growth of Festuca arundinacea in Beijing Fangshan
摘要
Abstract
Aimed at the present situation of the increase of the amount of the construction waste,optional stack,destroying vegetation,aggravating soil and water loss,engineering waste for the reconstruction of the artificial soil was used to realize the project of waste reduction and recycling use.In an orthogonally designed experiment of four factors,each at three levels,the effect of clinker particle diameter (factor A),dosage of ovine dung (factor B),the dosage of straw (factor C),dosage of charcoal powder (factor D) was analyzed on the follow indices (variables):rate of emergence,growth height,and biomass.The results showed that the order of importance of four factors on those indices (rate of emergence,growth height,and biomass) was:dosage of ovine dung (B),the dosage of straw(C),clinker particle diameter (A) and dosage of charcoal powder (D).The optimum disposition was the combination A1B2C2D2,(clinker particle diameter in 0～10 mm,dosage of ovine dung at 9 g,the dosage of straw at 220 g,dosage of charcoal powder at 6 g).The dosage which was at medium level (220 g) or the ovine dung was at medium level(9.0 g)showed a significant effect on the rate of germination and growth height.Test showed that the increase of the clinker size inhibited the emergence and growth; and the dosage of straw and ovine dung which was at medium level showed a significant effect on the rate of germination,growth height and biomasses.The dosage of charcoal powder had little influence on the rate of germination,growth height and biomass.关键词
