Abstract: Preparing 11 compound substrates with 6 basic substrates,  this paper studied effect of compound substrates on vegetative and reproduction growth of Freesia hybrida ‘Shangnong Purple Rose’, so as to screen the suitable compound substrate for its cultivation. The results showed that 3 compound substrates “peat + coco peat + inorganic materials” (C7, C8, C9) combinations were good for the vegetative growth of freesia. They could also improve the growth of scapes height and blossoming of floret, and C7 treatment had the highest abloom rate. The compound substrates “peat + coco peat + inorganic materials” were not only suitable for matter accumulation during the process of bulb growth, but also could improve reproduction coefficient, especially C8 treatment had the best effect. Comparing group “garden soil + peat + river sand” with group “garden soil + coco peat + river sand”, the growth and flowering status were quite similar, in which coco peat and peat were in the same proportion. The too large proportion of common soil would inhibit the growth and development of freesia, and could not meet the needs of freesia growth. Taken together, the compound substrate with “peat + coco peat + inorganic materials” was the best for freesia growth and development. It could improve its vegetative growth, blossoming and bulb development. It was also feasible to replace peat with reproductive coco peat for freesia cultivation. This study had a positive significance for guiding production practice in the future.

摘要: 以6种基质配制成11种复合基质栽培香雪兰,研究复合基质对香雪兰营养生长和生殖生长的影响,以期筛选出适合其栽培的复合基质。结果表明:“泥炭+椰糠+无机基质” (C7、C8、C9)组合有利于香雪兰的营养生长,也能较好地促进花葶高度的生长并有利于小花的开放,C7处理开花率最高。“泥炭+椰糠+无机基质”组合不仅有利于种球生长过程中物质的积累,同时还能提高繁殖系数,尤其以C8处理效果最佳。“园土+泥炭+河沙”组合与“园土+椰糠+河沙”组合进行比较,在椰糠与泥炭同等比例下,两组植物的生长及开花状况相当。基质中园土比例过大会抑制香雪兰的生长发育,不能满足其生长需求。综合来看,“泥炭+椰糠+无机基质”组合最有利于香雪兰的生长发育,在营养生长、开花及种球发育等方面均起到良好促进作用,且以再生性强的椰糠部分替代不可再生性的泥炭用于栽培香雪兰是可行的,此研究对指导今后生产实践有积极意义。
