摘要
以黄瓜品种"津联1号"为试材,腐熟和未腐熟2种菇渣为主要育苗基质,研究了5种不同颗粒粒径菇渣的理化性质以及对黄瓜幼苗生长的影响,以期为菇渣作为设施育苗基质提供参考依据。结果表明:腐熟和未腐熟2种菇渣的容重、持水孔隙度、pH值、EC值与颗粒粒径呈负相关;总孔隙度、通气孔隙度与颗粒粒径呈正相关。黄瓜幼苗的栽培试验表明,粒径在≤3mm和≤5mm,总孔隙度在80%左右,通气孔隙度在20%以上的腐熟菇渣最适宜黄瓜幼苗生长,其它处理次之。
Taking cucumber variety ‘Jinlian No. l＇as test materials, fermented and unfermented two different kinds of mushrooms as major nursery matrix, based on five different particle sizes of mushroom residuals, physical and chemical properties impact on nursery effect were studied,to provide reference for mushroom residual as facility seedling matrix. The results showed that the bulk density,water holding porosity,pH value,EC value of the fermented and unfermented mushroom residuals was negatively correlated with the particle size;total porosity, aeration porosity were positively correlated with particle size. Through the cultivation of cucumber seedlings, the test showed in ≤3 mm and ≤5 mm diameter,the total porosity was about 80%. Composted mushroom residual with aeration porosity above 20% was the most suitable for the growth of cucumber seedlings, followed by other treatments.
