Abstract
An ordinary and trace elements compounded fertilizer contains N, P, K, ordinary elements including Ca, S, Mg and Si, trace elements including Fe, Mn, Zn and B, the shell of crustacean, and marine living things, and features rich nutrients, high calcium content of crops, preventing and eliminating diseases and pests, and increasing yield by 30% or more.
Description
The invention relates to a kind of fertilizer, relate more particularly to a kind of middle trace-element compound fertilizer and preparation method thereof.
In the requisite 15 kinds of nutritive elements of known plant growth, de-carbon, hydrogen, oxygen can derive from outside atmosphere and the rainwater, nitrogen, phosphorus, potassium are main nutrient elements, calcium, magnesium, sulphur are middle amount nutritive element, iron, zinc, copper, manganese, molybdenum, boron are micronutrient element, because many crops contain the calcium of more amount, amount nutritive element in states such as Japan also classify calcium as.Fertilizer type is a lot of in the prior art, and the single fertilizer that contains main nutrient elements is arranged, and such as nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, the composite fertilizer that contains main nutrient elements is arranged, the composite fertilizer of micronutrient element and main nutrient elements and micronutrient element fertilizer.But lack based on the composite fertilizer of middle amount nutritive element, micronutrient element or based on middle amount nutritive element fertilizer, the double composite fertilizer that contains the main nutrient elements micronutrient element.Since long-term a large amount of compound manure that uses the main nutrient elements of nitrogen, phosphorus, potassium high density, and ignored replenishing of middle amount nutritive element fertilizer.Caused the pernicious variation of soil nutrient structure, the serious disproportion of nitrogen, phosphorus, potassium and middle amount nutritive element fertilizer.In the fertilising that Britain sulphur association is recommended, the optimum amount of nitrogen and sulphur should be 3: 1 to 5: 1.Owing to a large amount of applied nitrogens, the ratio of nitrogen and sulphur was up to 10: 1 in the Asia.According to 1993 the 3rd phases the 22nd page of introduction of " phosphate fertilizer and multiple fertilizer " magazine, the ratio of Chinese nitrogen and sulphur surpasses 100: 1, and the Asia is becoming the area of the most scarce middle amount nutritive element in the plant.On 1,000,000,000 hectares the soil, 70% soil magnesium deficiency is arranged, 70% lack of soil sulfur and silicon in Latin America.
Chinese patent CN1033617A discloses a kind of phosphogypsum long-term fertilizer and manufacture method thereof, be characterized in, when utilizing calcium sulphate hemihydrate to be converted into dihydrate gypsum, with dissolved fertilizer " curing " in dihydrate gypsum, the fertilizer component is slowly discharged, and phosphogypsum or gypsum play the carrier function of slowly-releasing; This invention provides the manufacture method by the long-acting compound fertilizer of phosphogypsum or gypsum as fertilizer sources component carrier, and this method is with phosphogypsum or gypsum partial dehydration, allows it with fertilizer component mixing, granulation, drying.The used fertilizer component of this invention is water-soluble known chemical fertilizer and trace element, such as urea, ammonium nitrate, Repone K, saltpetre, vitriolate of tartar, ammonium phosphate, potassium primary phosphate, SODIUMNITRATE, zinc sulfate, boric acid, ammonium molybdate, and by two or more above-mentioned compound manure of forming.The shortcoming of this invention is to be carrier with phosphogypsum or gypsum, and used fertilizer component is water-soluble chemical fertilizer, and calcium, magnesium, phosphate fertilizer and other water-fast chemical fertilizer can not the as fertilizer sources components.
The object of the present invention is to provide a kind of housing and remaining marine organisms of part with marine organisms shell, Crustacean is major ingredient, can satisfy the compound manure of Different Crop centering micronutrient element needs for crop provides main nutrient elements nitrogen, phosphorus, potassium and various middle trace element.
It is major ingredient that second purpose of the present invention provides a kind of housing and remaining marine organisms of part with marine organisms shell, Crustacean, can satisfy the compound manure of Different Crop centering micronutrient element needs for crop provides various middle trace elements.
