Abstract
The invention discloses a chitosan-fulvic acid compound fertilizer and a preparation method thereof. The compound fertilizer comprises chitosan, fulvic acid, nitric phosphate, urea, urea formaldehyde, diammonium phosphate, potassium sulphate, medium and trace elements and rare earth elements. In the preparation method, the medium and trace elements are chelated by taking chitosan and fulvic acid as chelating agents, and a chelated liquid is taken as a bonding agent for producing and granulating simultaneously. The invention has the advantages that: the chitosan-fulvic acid compound fertilizer is only applied once without additional application in the entire growing period of crops, so that the cost can be lowered, the labor productivity is lowered, the problems of slow fertilizing at an early stage and insufficient fertilizing at a later stage existing in an ordinary fertilizer are solved, mutual help is given in an emergency, and the utilization ratio of the fertilizer is increased; the medium and trace elements are chelated by using the chitosan and the fulvic acid respectively, so that the chelating efficiency of the medium and trace elements is increased, and the absorption and utilization ratio of crops on the medium and trace elements is increased; and the chelated liquid is taken as a granulating bonding agent, so that the granulating rate is high, the production efficiency is high, other bonding agents do not need to be added, and the cost is saved.
Description
Technical field
The present invention relates to a kind of composite fertilizer, specifically a kind of chitin xanthohumic acid composite fertilizer and preparation method belong to the agriculture production fertilizer field.
Background technology
At present, ordinary compound fertilizer or early stage are for fertile fast, or the later stage is for fertile not enough, and nutritive element is not comprehensive, and is very difficult consistent with plant growth cycle nutrient demand, repeatedly uses, make easily that farm crop excessive growth, lodging, disease resistance are poor, poor quality, yield poorly, and cause soil compaction, nutrient loss, contaminate environment, after using ordinary compound fertilizer, crop blade face pore openness is big, and root system is undeveloped, and the drought resisting anti-adversity ability is poor.
Summary of the invention
In order to address the above problem, the invention provides a kind of chitin xanthohumic acid composite fertilizer and preparation method, described compound fertilizer can be supplied the nutritive element of farm crop whole growing, uses and once can satisfy the demand of crop whole growing to nutritive element, reduce nutrient loss, prevent crop excessive growth, lodging, and can improve soil physical and chemical property, increase rhizospheric microorganism, stimulate root growth, improve the crop disease-resistant drought-resistant ability, increase output and improve quality.
Technical scheme of the present invention is:
A kind of chitin xanthohumic acid composite fertilizer, the composition of described composite fertilizer comprises:
Chitin, xanthohumic acid, nitric acid phosphorus, urea, urea formaldehyde, diammonium phosphate, vitriolate of tartar, middle trace element and rare earth element;
Described chitin is for example to extract the organisms such as shell of shrimp, crab, insect from joint animal to be prepared from, and is a kind of water miscible biological polyoses; Chitin is a kind of water miscible biological polyoses, contains in its molecular structure-NH
2(amino) produces sequestering action with middle trace element, the validity of trace element in can increasing, and chitin is the good substratum of soil microorganisms simultaneously, can promote that soil microorganisms grows, and stimulates root system development, strengthens the crop drought resistance lodging tolerance;
Described xanthohumic acid is to be raw material with plant slag body, through biological fermentation, and a kind of multivalence phenol type aromatics produced and the polycondensate of nitrogen compound; The solvability of xanthohumic acid is good, and micro-ability is strong in the chelating, can improve the soil simultaneously, increases soil fertility, and improves the crop drought resistance resistance against diseases;
Trace element is nitrocalcite, sal epsom, zinc sulfate, ferrous sulfate, manganous sulfate, copper sulfate, boric acid and ammonium molybdate in described; Trace elements are the necessary nutritive elements of plant growth in various, lack to cause easily that crop disease-resistant is poor, dysplasia, yield poorly even have no harvest poor quality;
Described rare earth element comprises one or more in rare earth nitrate, rare earth chloride, sulfuric acid rare earth, the acetic acid rare earth, and described rare earth comprises one or more in lanthanum, cerium, praseodymium, the neodymium; Rare earth has the crop of adjusting bulk-growth, strengthens drought resisting, cold-resistant, disease resistance, the effect of improvement quality of agricultural product and increase output.
Each composition is according to the following weight parts proportioning in the described composite fertilizer:
Chitin 3～8kg, xanthohumic acid 3～8 kg, nitric acid phosphorus 10～30kg, urea 10～30 kg, urea formaldehyde 10～30 kg, diammonium phosphate 15～30 kg, vitriolate of tartar 10～40kg, nitrocalcite 0～2 kg, sal epsom 0～2 kg, zinc sulfate 0～1 kg, ferrous sulfate 0～1 kg, manganous sulfate 0～1 kg, copper sulfate 0～1 kg, boric acid 0～1 kg, ammonium molybdate 0～0.5 kg, rare earth element 0.1～0.5 kg.
Preferably, each composition is according to the following weight parts proportioning in the described composite fertilizer: chitin 4～7kg, xanthohumic acid 4～7 kg, nitric acid phosphorus 12～28kg, urea 12～28 kg, urea formaldehyde 12～28 kg, diammonium phosphate 17～28kg, vitriolate of tartar 12～38 kg, nitrocalcite 0.5～1.5kg, sal epsom 0.5～1.5kg, zinc sulfate 0.2～0.8kg, ferrous sulfate 0.2～0.8 kg, manganous sulfate 0.2～0.8kg, copper sulfate 0.2～0.8kg, boric acid 0.2～0.8kg, ammonium molybdate 0.1～0.4 kg, rare earth element 0.2～0. 4kg.
