Background technology
China is large agricultural country, and along with the fast development of industrialized agriculture, the reality that land output ability and productivity effect increase severely is worth certainly.Be accompanied by the cropping system of industrialized agriculture, induced soil-borne disease and root knot nematode to increase the weight of to occur.
Root knot nematode is a kind of omnivory plant pathogeny line insect of height specialized form.Nematode host range is extensive, and 30 various vegetables such as melon, the solanaceous vegetables of often causing harm, beans and radish, calabash radish, lettuce, Chinese cabbage can also be propagated some fungus and bacterium venereal diseases evils.The root of the various vegetables of root knot nematode main harm, shows as lateral root and fibrous root compared with normal increases, and on the fibrous root of young root, forms the spherical or conical white root nodule differing in size, and what have is beads shape.Short and small, slow, the leaf color anomaly of killed strain overground part growth, result is few, yields poorly, and even causes plant dead ahead of time.
Monobromomethane is as processing soil treatment agent, kills soil fungi and root knot nematode has special efficacy.But because monobromomethane consumes ozone, international community's Montreal Protocol on Substances that Deplete the Ozone Layer amendment is clearly listed in controlled substance.Therefore, exploitation one can effectively be killed soil fungi and root knot nematode, can not destroy again the processing soil treatment agent of ecotope simultaneously and produce significant to farm crop.
Summary of the invention
The present invention is in order to make up the defect of prior art, and a kind of go out soil fungi killing root-knot nematode slow-releasing fertilizer and production method thereof of environmentally friendly, Sustainable Production is provided.
The present invention is achieved through the following technical solutions:
The one soil fungi killing root-knot nematode slow-releasing fertilizer that goes out, is characterized in that, its composition comprises: lime nitrogen 60 ~ 70%, ammonium polyphosphate 8 ~ 12%, potassium sulfate 8 ~ 12%, xylogen 3 ~ 6%, Starch Adhesive 3 ~ 6%, gac 2 ~ 4%, amino acid/11 ~ 3%, is more than weight ratio.
The present invention's soil fungi killing root-knot nematode slow-releasing fertilizer that goes out, preferred version is that its composition comprises: lime nitrogen 65%, ammonium polyphosphate 10%, potassium sulfate 10%, xylogen 5%, Starch Adhesive 5%, gac 3%, amino acid 2%, is more than weight ratio.
The go out production method of soil fungi killing root-knot nematode slow-releasing fertilizer of the present invention, is characterized in that:
(1). production stable state lime nitrogen, get the lime nitrogen that accounts for gross weight 60 ~ 70%, 2 ~ 4% gac, 0.5 ~ 1.5% Starch Adhesive, 1 ~ 3% xylogen, mix stable state lime nitrogen stand-by;
(2). produce fertile core, get the ammonium polyphosphate of gross weight 8 ~ 12%, 8 ~ 12% potassium sulfate, 0.5 ~ 1.5% starch mixture, 0.5 ~ 1.5% xylogen, after mixing, then with the stable state lime nitrogen extrusion granulation preparing, fertile core;
(3). film, get gross weight 1 ~ 3% xylogen, 2 ~ 4% Starch Adhesives, 1 ~ 3% amino acid furnishing pasty state, is evenly coated in mashed prod on fertile core, is dried and can obtains product.
In described step (2), the particle diameter of the fertile core of gained is 1 ~ 2mm.
In described step (2), the particle diameter of products obtained therefrom is 1.2 ~ 4mm.
The invention has the beneficial effects as follows: the soil fungi killing root-knot nematode slow-releasing fertilizer that goes out of gained of the present invention is not only with low cost, easy to use, and has fertilizer effect, noresidue simultaneously, has no side effect, and has environment friendly, and Sustainable Production, makes up the disappearance of comprehensively eliminating monobromomethane.
