园林废物堆肥产品作花卉栽培代用基质的试验

Experiment of green waste compost products as substrates for flower cultivation

采用不同比例园林废物堆肥产品替代泥炭作为花卉基质,开展一串红(Salvia splendens)、矮牵牛(Petunia hybrida)的栽培试验,分析植物各项生长指标和品质指标以评价其可行性。结果表明:添加适量的园林废物堆肥产品可明显改善花卉的生长和品质,不同基质配比对一串红和矮牵牛的生长影响各异。园林废物堆肥占基质的10%、20%、30%时,一串红长势较好;堆肥产品占基质的30%、40%时,矮牵牛长势较好;堆肥产品添加比例高于40%和50%时,分别对一串红、矮牵牛的生长有一定程度的抑制作用。

The Salvia splendens and Petunias hybrida cultivation experiments were carried out with different proportion of garden waste compost products for peat as culture substrates of flowers. The feasibility was evaluated by analyzing the plant growth index and quality index. The results show that the right amount of garden waste compost products can significantly improve the growth and quality of the Salvia splendens and Petunias hybrida. The substrates ratios of garden waste compost have different effects on the growth of the Salvia splendens and Petunias hybrida. The Salvia splendens grow better when the garden waste compost in the culture substrates account to 10% , 20% , 30% . The Petunias hybrida grow better when garden waste compost products account to 30% and 40% of the substrates. The growth of Salvia splendens and the Petunia hybrida are inhibited when the proportion of green waste compost is 4 0 % , 5 0 % or higher, respectively.
