黄瓜菇渣基质育苗营养液配方的初步研究

Nutrient Solution for Producing Cucumber Seedling by Using Mushroom Production Residue

菇渣基质是一种新开发替代草炭的基质,研究其在园艺作物栽培和育苗中的配套应用技术有重要意义。以菇渣为试验材料,采用完全随机设计,研究了菇渣与蛭石混配用于黄瓜穴盘育苗的配套营养液配方。结果表明,综合考虑各项指标,在本试验条件下,处理1[Ca(NO3)2.4H2O∶KH2PO4∶KNO3=329∶97.33∶219.33]的营养液配方对黄瓜菇渣基质育苗的促进效果最优,这一结果为菇渣在黄瓜育苗上的应用提供了科学依据和技术指标。

Mushroom residue is a new substrate replacing peat moss and vermiculite mix for cucumber seedling production in China.Nutrient solution for this special seedling soilless mix is need for using this new resource for cucumber seedling production.Different nutrient solution recipes were tested on cucumber seedling production using mushroom production residue and vermiculite mix with completely randomized experiment design.The results showed that the nutrient solution Ca（NO3）2 · 4H2O ∶ KH2PO4 ∶ KNO3 = 329 ∶ 97.33 ∶ 219.33 best promoted cucumber seedling growth.This is the first nutrient solution recipe for cucumber seedling production using mushroom production residue and vermiculite mix.
