摘  要:
以辣椒'青农干椒2号'为试材,以不同粒径(0.00~1.00、1.01~1.70、1.71~3.40、3.41~6.00mm和0.00~6.00mm混合粒径处理)的发酵菇渣为育苗基质,研究不同粒径对菇渣基质理化性状和辣椒育苗效果的影响.结果表明:随着粒径增大,菇渣基质的总孔隙和通气孔隙呈上升趋势,容重、持水孔隙、EC值、pH、全氮、全磷和全钾的含量则随粒径增大呈减小趋势,不同粒径处理间存在显著差异.以粒径1.01~3.40mm的菇渣基质培育的辣椒幼苗株高、叶面积、干鲜质量等生长指标显著高于其它处理.粒径1.71~6.00mm的基质培育的辣椒幼苗根系总体积、根系总长度、根尖数显著高于其它处理,该试验范围内的粒径增大能促进根系发育.粒径为1.71~3.40mm的基质培育的辣椒幼苗蔗糖、蛋白质的积累量最高,粒径为1.01~1.70mm和3.41~6.00mm的处理次之.粒径1.71~3.40mm的基质培育的辣椒幼苗G值显著高于其它处理,粒径1.01~1.70mm和3.41~6.00mm处理次之,均显著高于粒径0.00~6.00mm处理的G值.综上,以发酵菇渣为培育辣椒穴盘壮苗的基质适宜粒径范围为1.01~3.40mm,不进行粉碎分级的0.00~6.00mm混合粒径基质不适合辣椒幼苗生长.

摘  要:
‘Qin Nong Dehydrated chili 2#'pepper variety were used as experimental material,and taken different particle size of fermented mushroom residue(0.00-1.00 mm,1.01-1.70 mm,1.71-3.40 mm and 3.41-6.00 mm 4 grades and 0.00-6.00 mm mixed)as nursery substrate.The physical and chemical properties of different particle size mushroom residue had been detected.Besides,the effects of different nursery substrates on the growth of pepper seedlings also been studied.The results showed that total porosity and aeration porosity of mushroom residue substrate increased with the particle size,while bulk density,water holding porosity,EC value,pH,contents of total nitrogen,total phosphorus and total potassium decreased with the particle size increase.There were significant differences among treatments with different particle sizes.When the particle size was 1.01-3.40 mm,plant height,leaf area,dry weight and fresh weight were significantly higher than other treatments.When the particle size was 1.71-6.00 mm,the total root volume,root total length and root tip number of pepper seedlings were significantly higher than other treatments.When the particle size was1.71-3.40 mm,the accumulation of sucrose and protein were significantly higher than other treatments.The treatment with particle size of 1.01-1.70 mm and 3.41-6.00 mm were next.When the particle size was 1.71-3.40 mm grade,the G-value was significantly higher than other treatments.Secondly,the particle size were 1.01-1.70 mm and 3.41-6.00 mm.G value was significantly higher than that of 0.00-6.00 mm treatment with particle size.Synthesis,the fermented mushroom residue substrate cultivation pepper potting strong seedling suitable particle size was1.01-3.40 mm.
