The technical characterstic of Sunflower Receptacle special-purpose control-release fertilizer of the present invention is, utilize the coat fertilizer Nutrient Release of different coated fertilizers, while is according to the law of nutritive absorption of Sunflower Receptacle, carry out the different single controlled release fertilizer of planting that discharge the period of specific coating quantity composite, be equipped with phosphate fertilizer, potash fertilizer and trace element fertilizer again, accurately control nitrogen, phosphorus, potassium discharged by the requirement of Sunflower Receptacle growth nutrient absorbing rule in different periods, had formed the Sunflower Receptacle special-purpose control-release fertilizer.And carried out field experiment, obtained good effect.
Excellent results of the present invention is as follows:
1. nitrogen, phosphorus, potassium nutrition discharge and satisfy Sunflower Receptacle and absorb requirement the time of infertility
The different growth phases of Sunflower Receptacle have notable difference to absorption rate, the quantity of nitrogen, phosphorus, potassium.To two peaks that are absorbed with of phosphorus, one is growth early stage, is mainly used in root growth; Another is squaring period, and phosphorus is obvious to the effect that promotes to blossom and bear fruit.Sunflower Receptacle is along with growth of seedlings increases gradually to the absorption quantity of nitrogen, peaks to flowering period, and later basicly stable, the later stage slightly reduces.Absorbing state to potassium is that growth is preceding, mid-term is more, and the later stage obviously reduces.Special-purpose control-release fertilizer of the present invention is just according to the absorbing rule of Sunflower Receptacle to nitrogen, phosphorus, potassium, utilize nitrogen, phosphorus, potassium controlled release fertilizer and the conventional fertilizer of part of different time of releasing to carry out composite forming, can satisfy of the special requirement of the different growth phases of Sunflower Receptacle nitrogen, phosphorus, potassium three elements.
2. disposable fertilizer is imposed on the root system soil layer, increase fertilization effect
Sunflower Receptacle has huge root system, and main root buries dark 1.5～2 meters, 0.8～1 meter of lateral root extending obliquely, and most of root system concentrates in 0～40 cm layer of soil.Topdressing on producing at present mainly is to spread fertilizer over the fields in the face of land, and through intertillage, its degree of depth also is no more than 5 centimetres again, and fertilizer is far away apart from root system, particularly for the less phosphorus of movability, potash fertilizer, more is unfavorable for absorbing.Sunflower Receptacle special-purpose control-release fertilizer of the present invention is disposable executing in root layer soil before the Sunflower Receptacle sowing, and near apart from root system, fertilization effect is good.
3. nutrient progressively discharges with the absorption of Sunflower Receptacle, reduces fertilizer loss and fixing, improves utilization rate of fertilizer
China's Sunflower Receptacle main producing region soil meta-alkalescence, and contain more lime carbonate, this has the disadvantageous effect of two aspects for the current fertilizer variety of using, the one, quick-acting nitrogenous fertilizer such as urea, common composite fertilizer etc., the degree of depth is more shallow owing to topdress, just a large amount of ionic state nitrogen in fertilising back is present in upper soll layer, very easily causes the volatilization and the denitrification loss of ammonia.The 2nd, for phosphate fertilizer, water soluble phosphorous fertilizer lime carbonate direct and in the soil contacts, and forms calcium phosphate precipitation, loses fertilizer efficiency.The most of material composition particle of special-purpose control-release fertilizer is surrounded by a skim, does not directly contact with soil particle after being manured into soil, and its nutrient is that the absorption along with Sunflower Receptacle progressively discharges, the nutrient ion that retains in the soil is few, time is short, the loss of fertilizer and fixing the minimizing, and utilization ratio obviously improves.
