切花月季无土栽培技术的研究

该文对 10个引进切花月季品种与 4种栽培基质进行了研究筛选 .结果表明 ,在现代化温室环境条件下 ,‘BlackBeauty’、‘Dream’、‘Frisco’、‘GoldenGate’、‘Escimo’5个品种的综合性状表现较好 ,是中型花品种的推广品种 .4种无土栽培基质的筛选试验得出 ,岩棉栽培的切花月季在生产初期 (10个月的产花期 )的产量最高 ,‘BlackBeauty’、‘Dream’、‘Frisco’、‘GoldenGate’、‘Escimo’的产量分别达到 2 4 2 0、2 1 2 0、2 4 90、2 0 5 0、2 0 6 0枝 株 ,切花品质最好 ;泥炭、珍珠岩+蛭石 (体积比为 1∶1)栽培的切花品质、产量次之 ;椰糠栽培的切花月季最差 .该研究从理论上分析了无土栽培基质的选择原则 ,为切花月季的无土栽培提供了理论依据 .此外 ,该文给出了推广品种的栽培模式 .

Cultivation techniques of cut roses in soilless culture

Ten cultivars of medium flower cut roses were cultivated on four substrates (peat, coir, rockwool and vermiculite∶perlite 1∶1) in the computer controlled greenhouse in 2000 and 2001 to determine the yield and flower quality responses. All plants were fed with the same nutrient in an open soilless system. Significant differences were found among ten cultivars and among four substrates for yield and quality of cut flowers. The results show that five cultivars,‘Black Beauty’,‘Dream’,‘Frisco’,‘Golden Gate’,‘Escimo’were suitable for soilless culture, their flower quality and yield were better than those of other cultivars. Among four media,rockwool grown cut roses demonstrated the best yield and quality,such as the yield of ‘Black Beauty’ was 250 stems/m 2 in 10 month flushes, then the peat and the mixer,coir was the last. The effect of media on nutrient of cut rose leaves, the physical and chemical properties of different media and the cultural mode of five extending cultivars are also given in this paper.
