不同有机肥用量树叶复混基质对西葫芦的育苗效果

【目的】研究不同有机肥用量对基质理化性质、西葫芦植株形态指标和生理指标的影响,筛选出最适合西葫芦育苗的树叶复混基质配方。【方法】 以农业废弃物树叶和菇渣作为基质材料,用不同有机肥用量进行树叶基质的发酵试验,以西葫芦品种早青一代为试材,进行西葫芦穴盘育苗试验,验证树叶复混基质配方效果。【结果】 各个处理对西葫芦的根系部分生长有促进作用,且有机肥用量为10%的树叶复混基质(树叶∶菇渣=2∶1)是全部处理中效果较好,可以降低成本的最佳的基质配方。【结论】 在西葫芦穴盘育苗中可采用树叶复混基质代替草炭,降低育苗成本。

Preliminary Study on the Effects of Mixed Substrate of Leaves with Different Amount of Organic Fertilizer on Seeding Breeding of Zucchini

【Objective】 To study the effects of different amount of organic fertilizer on the physical and chemical properties of substrate, plant morphological and physiological indexes of zucchini and select the compound matrix formula of leaves which might be the most suitable for seedling raising of zucchini.【Method】 Using leaves and mushroom residue of agricultural waste as substrate materials, the fermentation test of leaf substrate was carried out with different organic fertilizer dosage, and the seedling raising test of zucchini point plate was carried out with zucchini variety "early green generation" to verify the formula effect of leaf compound matrix.【Result】 Each treatment could promote the root growth of zucchini, and 10% organic fertilizer (leaves: mushroom dregs = 2∶1) was the best matrix formula for reducing the cost of all treatments and had a good effect on the root growth of zucchini.【Conclusion】 In the seedling raising of zucchini, the compound substrate of leaves can be used to replace grass peat, and the cost of seedling raising can be reduced.
