Abstract
The invention provides sustained-release trace-element water-soluble fertilizer granules. The granule comprises a trace-element water-soluble fertilizer granular core and a sustained-release layer coating the outside of the trace-element water-soluble fertilizer core. The trace element water-soluble fertilizer granules are water-soluble fertilizer granules containing a single trace element or a mixture of multiple trace elements. The sustained-release trace-element water-soluble fertilizer granules have the technical effects that (1) trace-element water-soluble fertilizer can be slowly released for a long time, and the granules are suitable for crops having long growth cycles, such as potted flowers and nursery stocks, and are suitable for woody seedling cultivation; (2) a fertilizer is added into a medium in advance by using a mechanical method, labor is saved, and plants can grow normally just by watering; (3) the granules can be put in a cut medium to facilitate root development and strong growth.
Description
Technical field
The present invention relates to a kind of trace element water-soluble fertiliser granulates, belong to water soluble fertilizer technical field.
Background technology
Water soluble fertilizer (Water Soluble Fertilizer, be called for short WSF), it is a kind of polyelement composite fertilizer that can be completely water-soluble, it can promptly be dissolved in the water, more easily absorbed by crops, and its absorption rate is relatively high, and more crucially it can be applied to the industrialized agricultures such as spray drop filling, realize water-fertilizer integral, reach the usefulness that water-saving economizes fertile saving of labor.
But also there is following weak point in water soluble fertilizer: the crop 1) being not suitable for length in vegetative period; 2) water soluble fertilizer in soil its effect not as good in peat medium; 3) applications of water soluble fertilizers needs comparatively hi-tech, and takes a lot of work; 4) easily run off from growth medium, cause wastes and pollution; 5) used in combination the while of needing several, add cost.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of slowly releasing trace element water soluble fertilizer particle is provided.
Slowly releasing trace element water soluble fertilizer particle of the present invention, is made up of trace element water-soluble fertiliser granulates shape inner core and the slow release layer being wrapped in trace element water-soluble fertilizer inner core outside; Described trace element water-soluble fertiliser granulates is the water soluble fertilizer particle containing single trace element or the water soluble fertilizer particle containing various trace elements mixture.
The thickness of described slow release layer is 1:(25-50 with fertiliser granulates diameter ratio), the thickness of described slow release layer is 20-30 micron.
Slowly releasing trace element water soluble fertilizer particle of the present invention, has following technique effect:
1) trace element water-soluble fertilizer can be slowly released for a long time, be applicable to the long crop of growth cycle as potted flower, nursery stock, be very suitable for the cultivation of woody seedling.
2) can mechanically fertilizer be added in medium in advance, saving of labor.As long as add water, plant just can normal growth.
3) can be placed in cuttage medium, contribute to root development, robust growth.
Accompanying drawing explanation
Fig. 1 structural representation of the present invention.
Wherein, 1 is inner core, and 2 is slow release layer.
