Influence of different treatment with straw and straw’s thickness on forming-sod time and turf quality

Abstract

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.
