Description
Technical field
The invention belongs to agricultural planting industry field, be specifically related to fertilizer and preparation method thereof for a kind of tobacco seedling.
Background technology
Cultivating strong sprout is the primary link that tobacco produces, and is to obtain the suitable basis of producing tobacco leaf of high-quality.Allotment full-valence nutrition liquor has guaranteed the growth that tobacco seedling is healthy and strong.Nutritive element is dissolved in the water completely, and in whole seedling raising process, cured tobacco seedling obtains abundance, even, continual nutrient element.Thereby changed open country grow seedlings apply fertilizer with soil solution infiltration, fixing, run off and reduce the phenomenon of plant recovery of nutrient.Change the pouring fertilization mode of traditional spray, avoided the detrimentally affect of pouring to cigarette strain growth, guaranteed the clean and clean of cigarette strain blade, blocked the important channel that disease, worm, crop smothering are propagated.
Floating seedlings represents the advanced level of international tobacco seedling, the various countries such as the current U.S., Zimbabwe, Brazil are spread, this seedling raising manners is once bred as cigarette seedling, removed and in conventional seedbed system, heeled in process, not only reduce the amount of labour used of the work of growing seedlings, more reduced seedbed area, avoided heeling in the injury to root system, it is more neat that seedling stalwartness is unanimously conducive to seedling replanting grown in field.Kind of seedling industrialized production technology is the new agricultural technology growing up external beginning of the eighties late 1970s, and it is mainly used in vegetables and flowers and grows seedlings, and also can be used for farm crop as tobacco, cotton, the growing seedlings of economic nursery stock.
At present, tobacco floating seed rearing technology is in national widespread use, but grow seedlings in various places, fertilizer type is various, and cigarette seedling quality is uneven.So far also do not form industry, country's " tobacco seedling fertilizer " standard.Mostly adopt N, P
2o
5, K
2o macroelement fertilizer, also only limits to B, Zn, tri-elements of Mg if add trace element fertilizer, and many people think: become to be water become with matrix trace element just meet growth of seedling.1. plant-growth needs 16 kinds of necessary nutritive element (C, H, O, N, P, K, Ca, Mg, B, Fe, Cl, Na, Cu, Zn, S, Mn, its C, H, O are extensively present in water and air, and Ca, Cl, Mn, Na are present in in pvc material water bed, matrix with carriers such as the peat composed of rotten mosses, sand, stalks) and multiple beneficial element (Mo, Ti etc.); 2. to meet the required nutritive element of seedling growth rule simultaneously; 3. the balance of nutritive element need meet " minimum Nutrient Factor theory of control ", i.e. " bucket theoretical ".The tobacco seedling dedicated fertilizer now mostly using does not meet above-mentioned three conditions, thereby strong sprout, rate was low.
Summary of the invention
The present invention mainly solve nutrition unbalanced or use the shortcomings such as operation inconvenience and cause that cigarette seedling growing way is inhomogeneous, rate in the strong sprout problem such as low.
First technical problem to be solved by this invention is to provide a kind of tobacco seedling fertilizer.This fertilizer is made by the raw material of following weight proportion: primary ammonium phosphate 15.00～25.00%, saltpetre 40.00～50.00%, nitre ammonia phosphorus 30.00～40.00%, magnesium sulfate heptahydrate 0.01～0.50%, iron vitriol 0.02～1.00%, seven water manganous sulfates 0.01～1.00%, cupric sulfate pentahydrate 0.01～0.50%, Zinc Sulphate Heptahydrate 0.01～0.50%, boric acid 0.10～0.50%, four water ammonium molybdates 0.008～0.50%, 100g/L resistant to hydrolysis-stabilizing ion titanium aqueous solution 0.008～0.032%.
Preferably, above-mentioned tobacco seedling fertilizer, is made by the raw material of following weight proportion: primary ammonium phosphate 18.00～22.00%, saltpetre 43.00～47.00%, nitre ammonia P 32 .00～36.00%, magnesium sulfate heptahydrate 0.10～0.30%, iron vitriol 0.15～0.35%, seven water manganous sulfates 0.10～0.30%, cupric sulfate pentahydrate 0.08～0.12%, Zinc Sulphate Heptahydrate 0.08～0.12%, boric acid 0.10～0.20%, four water ammonium molybdates 0.01～0.03%, 100g/L resistant to hydrolysis-stabilizing ion titanium aqueous solution 0.01～0.03%.
Further, preferably, above-mentioned tobacco seedling fertilizer, is made by the raw material of following weight proportion: primary ammonium phosphate 20%, saltpetre 45%, nitre ammonia phosphorus 34%, magnesium sulfate heptahydrate 0.20%, iron vitriol 0.20%, seven water manganous sulfates 0.20%, cupric sulfate pentahydrate 0.10%, Zinc Sulphate Heptahydrate 0.10%, boric acid 0.16%, four water ammonium molybdates 0.02%, 100g/L resistant to hydrolysis-stabilizing ion titanium aqueous solution 0.02%.
Second technical problem that the present invention solves is to provide the preparation method of fertilizer for above-mentioned tobacco seedling.The method comprises the following steps:
A, by proportioning, primary ammonium phosphate, saltpetre, nitre ammonia phosphorus are mixed at normal temperature condition, mixing limit, limit adds resistant to hydrolysis-stabilizing ion titanium aqueous solution, and mixture is dried to free water content in 1wt%, pulverizes, standby;
