摘要
以(石至)石、锯末、煤渣、河沙、泥炭为原料,按不同体积比配制了十种山茶花人工盆栽基质。经三年栽培试验,筛选出了(石至)石:泥炭=2:1,(石至)石:河沙:泥炭=10:5:1两种适宜于茶花生长发育的理想人工盆栽基质。七种山茶花无土栽培施肥试验证明,春夏季施用高氮高磷钾的23-12-15配方肥,秋冬季施用低氮高磷钾的5-20-26配方肥,或者全年施用高氮高磷钾的23-12-15配方肥,每20天每盆浇施200 ml肥液,能使山茶花在有限的盆栽基质中长期健壮生长,开花量多,且能保持很强的生长势。
Ten different kinds of artificial potting media used for the culture of Camellia japonica L. were mixed with vermiculite, saw-dust, river sand, peat and coal cinder. Two good mixed media, vermiculite : peat = 2:1 and vermiculite : river sand: peat = 10:5 : 1, in which the plants of C. japonica L. grew and bloomed excellently, have been obtained by means of three-year-culture experiments. Under the same level of applying micronutrients, seven fertilized treatments with different levels of N, P and K for the soiless culture were designed. The experiments showed that 23-12-15 formulation with high levels of N,P and K applied in spring and summer and 5-20-26 formulation with low level of N, and high levels of P and K applied in autumn and winter or 23-12-15 formulation with high levels of N, P and K applied once every twenty days throughout a year all can make the plants grow vigorously for a long time, bloom greatly and keep up their strong growing-potential in their limited potting media.
