一、要掌握盆景用土的标准:1.酸碱度要适宜:根据不同树桩的习性,要调整适宜的PH值。如五针松树桩PH值以4.5-6.5为宜,不能用低于PH4.5以下的强酸性土壤。因为这种强酸性土壤含硫浓度大于植物根系细胞液的浓度,根毛不能吸水,反而使细胞液渗到盆土中去,结果导致植桩失水萎蔫以致死亡。2.营养要丰富:所配制的培养土要求肥沃,排水和透气性能良好,持水保肥能力强。并且有机物和各种营养成份的含量均要求能满足源源不断地供给树桩生长发育的需要。3.团粒结构要好:配制的培养土中要求从芝麻到蚕豆大的粗细不等的团粒结构均有。盆土结构良好,可使盆土的水、肥、气、热等条件适宜,协调供应。
First, to grasp the bonsai soil standards: 1. pH should be appropriate: According to the different stump habits, to adjust the appropriate PH value. Such as the five-pin pine stump PH value of 4.5-6.5 is appropriate, can not be less than PH4.5 below the strong acid soil. Because this strong acid soil sulfur concentration greater than the concentration of plant cell fluid, root hair can not absorb water, but the cell liquid to infiltrate into the basin soil, resulting in wilting water loss caused by planting piles and death. 2. Nutrition to be rich: the preparation of fertilizers require fertile soil, drainage and ventilation performance is good, water and fertilizer ability. And organic matter and various nutrient content are required to meet the steady supply of stump growth and development needs. 3. The pellet structure is better: the preparation of culture soil requirements ranging from sesame to broad beans have different sizes of the aggregate structure. Pentu structure is good, can make basin water, fertilizer, gas, heat and other conditions suitable, coordinated supply.
