Abstract

The invention belongs to a compound fertilizer of a silky oak and particularly relates to a special compound fertilizer in a seedling stage of jacaranda. The special compound fertilizer is composed of major elements such as N, P and K, element fertilizers such as Mn, Mo, Zn, Cu, Fe and B and a plant growth regulator. The silky oak has the advantages that the tree performance is graceful and gorgeous, the trunk is straight, the crown is elliptical, a green shade is like an umbrella, the flower season is long, the color is romantic, the blossom is spectacular and the like. The silky oak has a high appreciation value, is suitable for being planted on a road side, is capable of preventing sunstroke for pedestrians and is an excellent landscaping woody flower variety. The preparation process of the fertilizer comprises the fertilizer is produced by processes of grinding and mixing of a large amount of elements, microelement fertilizers and plant growth regulators according to required proportions, and the compound fertilizer of the silky oak comprises active constituents such as nitrogen, phosphorus, potassium and microelement and particularly comprises 29.10%-37.20% of nitrogen, 17.71%-26.52% of phosphorus pentoxide, 8.84%-15.02% of potassium oxide, 0.125%-0.392% of iron, 0.045%-0.107% of manganese, 0.018%-0.045% of zinc, 0.018%-0.023% of copper, 0.004%-0.031% of boron and 0.001%-0.005% of molybdenum.

Description

technical field [0001] The invention relates to the field of compound fertilizers in forestry production, and relates to a special fertilizer for silver birch seedlings. Background technique [0002] The invention belongs to a compound fertilizer, in particular to nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), and other macroelements and manganese (Mn ), molybdenum (Mo), zinc (Zn), copper (Cu), iron (Fe), boron (B) and other element fertilizers and plant growth regulator special compound fertilizer for silver birch seedling stage. [0003] Silver birch (Grebillea robusta A Cunn ex R.Br) is a large evergreen tree belonging to the family Longanaceae. It is tall and has a diameter at breast height of up to 1 meter.
