摘要
采用泥炭﹕珍珠岩﹕沙(1﹕1﹕1)、珍珠岩和水3种栽培介质及3个配方的营养液对红掌进行无土栽培,结果表明,以水作为介质,营养液配方为N﹕P2O5﹕K2O=4﹕1﹕8的培养液对红掌株高、叶片数及植株净重的增加效果最好,但水培对红掌开花无促进作用。以水为介质的红掌经高温(32℃)胁迫后叶片黄化数为零,显著低于其它处理组;而在泥炭﹕珍珠岩﹕沙(1﹕1﹕1)介质中,则是6-BA处理的叶片黄化数明显低于其它处理组。
Effects of three substrates (peat : perlite : sand = 1 : 1 : 1, perlite and water) and three nutrient solutions (N : P2O5 : K2O = 3.387 : 1 : 5.661, 6 : 1 : 8 and 4 : 1 : 8) on the growth of Anthurium andraeanum were studied. The results showed that nutrient solution of N : P2O5 : K2O = 4 : 1 : 8 was the best for the height, weight and leaf number of the plant when cultured in water. Under the heat stress (32℃), water substrate could significantly reduce the leaf yellowing of Anthurium andraeanum. Meanwhile, 6-BA could significantly decrease the number of yellow leaves when cultured in the substrate of peat : perlite : sand = 1 : 1 : 1.
