- 摘要:
- 以辣椒品种‘航椒S605’为试材，以椰糠为主要原料，添加沙子和有机肥，筛选适合新疆和田地区辣椒(Capsicum frutescence L.)穴盘苗生长的椰糠型复合基质配方。采用不同体积比组成6种育苗基质配比的方法进行辣椒穴盘育苗，通过对各复合基质理化性质的测定、分析，辣椒幼苗生长状况、生理指标的观测和比较，研究不同复合基质对辣椒穴盘苗生长的影响。结果表明：椰糠∶沙子∶有机肥=22∶1∶1的辣椒幼苗在株高、茎粗、全株干鲜质量、根体积、壮苗指数、G值以及叶绿素含量方面均优于对照（椰糠∶有机肥=20∶1）及其它处理。其壮苗指数值为0130 8，高于对照（CK）2167%。椰糠∶沙子∶有机肥=22∶1∶1的复合基质作为辣椒穴盘幼苗生长的育苗基质，有利于培育辣椒壮苗。关键词：辣椒；椰糠；沙子；有机肥；育苗
- Abstract:
- Coir dust was used as the main raw material,sand and organic fertilizer were added to screen the formula of coir dust composite matrix suitable for the growth of pepper(Capsicum frutescence L.) plug seedlings in Hotan region of Xinjiang.‘Hangjiao S605’ pepper variety was used as test materials,coir dust,sand and organic fertilizer were used as raw materials,six kinds of seedling substrates with different volume ratios were used for pepper plug seedling,through the determination and analysis of physical and chemical properties of each composite matrix,observation and comparison of physiological indexes and growth status of pepper seedlings,the effects of different composite substrates on the growth of pepper plug seedlings were studied.The results showed that with a view to coir dust∶sand∶organic fertilizer=22∶1∶1 was superior to control (coir dust∶organic fertilizer=20∶1) and other treatments in plant height,stem diameter,whole plant dry fresh weight,root volume,seedling index,G value and chlorophyll content.The strong seedling index was 0130 8,which was 2167% higher than CK.Coir dust∶sand∶organic fertilizer=22∶1∶1 composite substrate was used as a seedling substrate for pepper plug seedling growth,it was conducived to the cultivation of strong pepper seedlings.
