Abstract

The utility model relates to a fertilizer rod which is exclusively used for the fertilizing of trees, lawns, etc., composed of an upper cover 2, a rod body 3, and fertilizer 4 inside the rod. The upper cover 2 is provided with a hole 1; the outer side of the rod body is coated with paraffine or an oil film; the lower part of the rod body 3 presents a tip shape for the convenience of drilling soil; the lower part of the rod body 3 is provided with a hole 6; a fertilizer rod can be directly inserted into the soil; the fertilizer 4 inside the rod absorbs water content from the upper hole 1 and slowly releases from the bottom hole 6 after dissolving. The utility model has the advantage of high efficiency. A fertilizer effect period can last six to eight months.

Description

Fertilizer rod

The utility model is a kind of Fertilizer rod, is exclusively used in the fertilising of squeezing into of plants such as trees, lawn.

Any growth and development of plant all be unable to do without the rich soil, especially the artificial cultivation plant usually needs artificially applying fertilizer, the general root system of land for growing field crops crops is simple, the reproductive growth cycle is short, available base manure, mode such as topdress are applied fertilizer, and trees, lawn are then different, because the plantation growth time is long, the root system complexity is difficult for fertilising.At present, the special coated fertilizer of the fruit tree that the trees dedicated fertilizer has the inventor to develop, coated fertilizer are used for fruit tree can reach the effect that slow discharges, but it does not have to break through on fertilizer practice, also need ditch and fertilizer could be executed into soil, takes a lot of work, time-consuming, effort.The Fertilizer rod of directly squeezing into soil does not also have at present.

The purpose of this utility model is a kind of Fertilizer rod of design, and Fertilizer rod can directly be squeezed into soil under the situation of not destroying soil and root system of plant, and fertilizer is that slow discharges in the rod, thereby it is simple, long-acting to reach the trees fertilising, solves the problem of trees fertilising difficulty.

A kind of Fertilizer rod provided by the utility model is characterized in that, is made up of fertilizer 4 in loam cake 2, barred body 3 and the rod, and is porose 1 on the loam cake 2, barred body 3 outside paraffine or oil films, and barred body 3 bottoms 5 are downward to be the tip shape, barred body 3 bottoms 5 porose 6.

Use the designed Fertilizer rod of the utility model, need not ditch, need not destroy soil and root system of plant, can directly Fertilizer rod be squeezed into soil with wooden mallet.Barred body 3 bottoms 5 are the tip shape downwards, are convenient to pass between the wrong vertical complicated root system of trees, enter soil.Be used for the lawn fertilising, can destroy turf, directly squeeze into soil.Rod loam cake 2 is porose 1, and barred body 3 bottoms 5 are porose 6, so that after fertilizer throws soil into, by raining or water, moisture 1 enters in the rod along the hole, around fertilizer 4 slowly dissolves and discharges into tree root along bottom hole 6, thereby reaches the effect of fertilising.Because fertilizer is to enter soil by hole 6 in the rod, so can slowly discharge, do not subject to leaching loss, thereby improve the service efficiency of fertilizer, and be reached for the effect that trees supply fertilizer for a long time, show sustainable 6～8 months of fertilizer efficiency period according to inventor's test.

Describe the structure of fertilizer in detail below in conjunction with accompanying drawing.Fertilizer rod is made up of fertilizer 4 in loam cake 2, barred body 3 and the rod, and loam cake 2 can be made upper plate, porose 1(such as Fig. 2 on the loam cake 2, on be stamped 4 holes), can make rainwater or water by hole 1 to enter in the Fertilizer rod.Barred body 3 usefulness paper pulp are made, so that fertilizer release finishing back barred body rots and noresidue in the rod.Barred body 3 outside paraffine or oil films are in case barred body 3 makes moist softening and the fertilizer leakage.The garden tubular is made on barred body 3 tops, and the cone (as Fig. 1, Fig. 3, Fig. 4, for having the cone of three corner angle) that has corner angle is made in barred body 3 bottoms 5, or makes down cone, is convenient to beat with wooden mallet bury.Barred body 3 bottoms 5 are porose 6, and slit-shaped can be made in hole 6, is positioned at any position of barred body 3 bottoms 5, also can be positioned at the tip position (as Fig. 1) of barred body bottom 5, and fertilizer 4 suction back dissolvings make the fertilizer diffusion discharge into soil by hole 6 in the rod, absorb for root system.Fertilizer 4 can be water miscible in the rod, also can be slow.The composition of fertilizer 4 can be prepared specially according to the demand of fertilising object, also can prepare general fertilizer according to the required nutrient situation of general plant.In order to provide balanced nutritious to plant, improve fertilizer utilization efficiency, reach long-acting for fertile, fertilizer slightly water-soluble preferably in the rod, fertilizer is furnished with macroelement nitrogen, phosphorus, potassium, calcareous fertilisers, moderate-element iron, magnesium in the rod, micronutrient boron, zinc, manganese, copper, molybdenum etc., organic short root material such as active humic acid class, anti-corrosion material such as carbolic acid etc., its best proportioning is:

250 kilograms/ton in urea

100 kilograms/ton of ammonium nitrates

100 kilograms/ton of sulphur ammoniums

(64%) 250 kilogram/ton of phosphorus ammonium

200 kilograms/ton in potassium chloride

100 kilograms/ton of active humic acid, trace element, moderate-elements etc.
