笔者制作盆景近20年,栽种制作过数以百计的紫薇盆景。通过观察比较、分析研究,认为影响紫薇开花有下列几个方面的原因。一、土壤板结笔者认为要想紫薇开花好,必须勤换盆土。紫薇根系发达,由于长势迅速,消耗水肥量大,土壤极易板结,导致水肥保持力弱,透气性差,这是紫薇开花不理想的主要原因。如能每年换一次盆土最好,但至少要比其他树木盆景换土勤些。二、肥水不足不论园林用树,还是盆景制作,都必须注重紫薇的肥水管理。在紫薇生长期以每周施一次淡粪(尿)水或腐熟的油饼肥水为好。高温季节以早晚各浇一次水为妥。如果紫薇严重失水,将会导致落叶、枯梢甚至整株死
Bianjing author for nearly 20 years, planting hundreds of crape myrtle bonsai. By observing and comparing, analyzing and researching, it is considered that there are several reasons that influence the flowering of crape myrtle. First, the soil balance I think in order to crape myrtle blossom, must Qincha pedestal. Crape myrtle developed root system, due to the rapid growth, consumption of large amounts of water and fertilizer, soil extremely easy to knot, leading to weak water and fertilizer retention, poor air permeability, which is crape myrtle flowering is not ideal for the main reason. If you can change the basin every year, the best, but at least more than other trees bonsai soil Qin better. Second, lack of fertilizer Whether garden trees, or bonsai production, we must pay attention to Ziwei fertilizer and water management. Lagerstroemia in the growth of the weekly application of light manure (urine) water or decomposed cake fat as well. High temperature season sooner or later poured a water properly. If Lagerstroemia severe dehydration, will lead to deciduous, blight or even the whole plant died
