据连续两年试验结果,以农用岩棉作康乃馨栽培基质,定期供给专用营养液,并防治病虫害,适时摘心抹芽和去侧蕾,康乃馨植株生长整齐,长势旺,分枝多,叶面积大,开花提早,花大圆整,花枝挺拔,切花产量高,综合性状显著优于常规土培。 材料和方法 循环供液岩棉培(简称岩棉培):采用南京市玻璃纤维研究院二所研制提供的农用岩棉,切成长100厘米、宽20厘米、高6～7厘米的岩棉块,排成8米长的栽培床,用无纺布和黑膜包裹,其内放置一根按定植株距打孔的供液软管,在1米宽的畦面上排3床,床距20厘米。用WB型180瓦水泵供液,冬季3～5天1次,夏季每天1次,每次15～30分钟。营养液浓度为N:187ppm,P:31ppm,K:234ppm,pH:5.5～6.5,EC:1.9mS/厘米。
According to the results of two consecutive years of experiment, we use the agricultural rock wool as the carnation cultivation medium, regularly supply the special nutrient solution, prevent and control the pests and diseases, timely pruning the buds and removing the side buds. The carnation plants grow neatly, grow vigorously, , Early flowering, large flower round, tall and straight flowering, cutting high yield, comprehensive traits significantly better than conventional soil culture. MATERIALS AND METHODS Recycling Fluid Rockwool (Rockwool): Using rockwool for agricultural use developed by Nanjing Glass Fiber Research Institute, cut into 100% rock wool block with width of 20cm and height of 6 ~ 7cm , Arranged in an 8-meter-long cultivation bed, wrapped with a non-woven fabric and a black film, in which a liquid supply hose perforated by a fixed plant was placed, and 3 beds were arranged on a 1-meter- cm. Use WB type 180W pump for liquid, 1 to 3 days in winter, 1 time in summer, every 15 to 30 minutes. The nutrient solution was N: 187 ppm, P: 31 ppm, K: 234 ppm, pH: 5.5 to 6.5, and EC: 1.9 mS / cm.
