【摘要】 运用五因素二次正交旋转组合设计法,研究不同处理稻秸基质(处理Ⅰ:稻秸+猪粪便+秸秆腐熟剂;处理Ⅱ:稻秸+猪粪便;处理Ⅲ:稻秸+尿素+秸秆腐熟剂;处理Ⅳ:稻秸+尿素)和不同基质厚度(10,15,20,25和30mm)对草皮成坪天数的影响。结果表明,对成坪天数影响最大的是处理Ⅰ基质,其次是基质厚度,再者是处理Ⅲ基质,其他2种基质对成坪天数的影响最小。在坪用价值为限定条件下,得出最优基质组合,其配比为处理Ⅰ为600g,处理Ⅱ为600 g,处理Ⅲ为0 g,处理Ⅳ为600 g,基质厚度为20 mm,成坪时间为36.33 d,坪用价值权重值为108.61。更多还原

【Abstract】 Use square,regressive and rotation with 5 factors design,researched on the different straw and straw’s thickness that influence the days of forming-sod(TreatmentⅠ: straw+pig’s dejectas+accelerating-humus powder;TreatmentⅡ: straw+pig’s dejectas;Treatment Ⅲ: straw+urea+accelerating-humus powder;Treatment Ⅳ: straw+urea;and factor V: 10,15,20,25 and 30 mm thickness).As the result,the mostly influence on the days of forming-sod is treatmentⅠ(straw),the second is straw’s thickness,the third is treatment Ⅲ.Others have little influence on this.In the limit of the turf quality,the best medium is 600 g of treatment Ⅰ,600 g of treatmentⅡ,0 g of treatment Ⅲ,600 g of treatment Ⅳ,20 mm of the straw’s thickness.The days of forming-sod of the medium are 36.33 d.And the weight value of turf quality is 108.61.更多还原
