Description
Technical field
The invention belongs to flower fertilizer preparing technical field is and in particular to a kind of preparation method of Flos Hibisci slow release fertilizer.
Background technology
Hibiscus syriacus L. (hibiscus syriacus linn.), Malvaceae, Hibiscuses, machaka, sprig is close starlike by yellow
Fine hair.Leaf rhombus is avette to triangular shape, long 3-10cm, wide 2-4cm, different 3 the splitting or do not split of the tool depth, and tip is blunt, base portion wedge
Shape, edge has irregular tooth and lacks, below along vein micro- by hair or nearly no hair.Hua Dan is born between an end axil, and calyx is bell, long
14-20mm, close by starlike down, sliver 5, triangle;Flower color has pure white, rose pink, pale purple, purplish red etc., and flower-shape is in
Mitriform, has single-lobe, multiple lobe, polyphyll several.Outside is dredged by cilium and starlike long pubescence.Capsule oval, about 12 millimeters of diameter, close
By the starlike fine hair of yellow;Seed kidney shape, back is by the long pubescence of yellow-white.The month at florescence 7-10.Hibiscus syriacus L. is a kind of very common in flower garden
The shrub seeds of flowering plants, central China each province originate in, all there is cultivation various places.Hibiscus syriacus L. is very strong to the adaptability of environment, more resistance to drying and lean
Lean, soil is required with strict, light and warm damp weather especially.Slightly shade tolerant, like warm, moist climate, resistance to pruning, heat-resisting
Resist cold again, but need covering overwinter in northern area cultivation, good water is wet and drought-enduring, soil is required not tight, in weight clay
Can growth.Sprout tillers is strong.The propagation method of Hibiscus syriacus L. has sowing, press strip, cuttage, plant division, but mainly uses cutting propagation on producing
And division propagation.The fertilising of Flos Hibisci mainly based on nitrogenous fertilizer, phosphate fertilizer and potash fertilizer, different growing stage apply fertilizer situation area
Not, as when branch starts to sprout, fast-growth should be promoted based on quick-acting fertilizer, need to add 2 fertilizer before buddingging,
Need during 5-10 month full blossom to add fertile twice and keep lasting fertility.
At present commonly use Flos Hibisci common fertilizer once being manured into soil, by the enzyme in multiple soil microorganisms and its secretion
Under effect, experience a series of biochemical changes, be constantly changing its form so as to increase mobility in soil, or even with
Water leaching loss and with gaseous state volatilization loss.According to measuring and calculating, China's fertilizer especially nitrogenous fertilizer this season utilization rate is relatively low, about 30%-35%, greatly
Part enters water body and air by the approach such as volatilization, leaching, runoff.This not only wastes the energy, also will cause soil simultaneously
Accumulation with harmful substances such as nitrate in water body and pollute environment.In addition, existing nitrogenous fertilizer or phosphate fertilizer, its nutrition is more single
One although plant growing can be promoted, but cannot meet requirement, and apply for a long time for the zinc deficiency of crop, resistance aspect
With being easily caused soil compaction, the consequence such as soil environment deterioration.Therefore, for improving utilization rate of fertilizer, mitigation causes because of fertilising
Environmental pollution, energy saving, increase soil fertility, realize agricultural year, high-quality, efficient, ecological, safety, develop effect of increasing production
Substantially, persistently length, low cost, raw material environmental protection, small investment, the simple new slow release fertilizer of production have very important meaning to fertilizer efficiency
Justice.
Content of the invention
It is an object of the invention in order to overcome above the deficiencies in the prior art to provide a kind of Flos Hibisci slow release fertilizer
Preparation method, improves the fertility of fertilizer, prolongation fertilizer release time, increases operation rate simultaneously.
Technical scheme is as follows:
A kind of preparation method of Flos Hibisci slow release fertilizer, comprises the steps:
