Abstract

The present invention relates to an inorganic fertilizer for the soilless culture of plants, particularly to a plant growth nutrient solution. The present invention is a suspension comprising 36 to 40 portions of ammonium sulfate, 63 to 77 portions of ammonium nitrate, 400 to 500 portions of triple superphosphate, 55 to 65 portions of potassium nitrate, 70 to 90 portions of magnesium sulfate, 400 to 600 portions of waste gypsum, 0.2 to 1.0 portion of sodium tetraborate, 0.2 to 1.0 portion of zinc sulphate, 0.2 to 1.0 portion of manganese sulphate, 0.2 to 1.0 portion of copper sulfate and 0.5 to 1.5 portions of ferrous sulfate. The expense of the production of one kilogram of vegetables by using the nutrient solution of the present invention amounts to RMB 1 to 2 jiao.

Description

Plant growth nutrient solution
The present invention relates to the mineral manure of a kind of mineral manure, particularly a kind of soilless cultivation plant.
The many in the world countries of the nutritive medium of soilless culture all had report.According to＜foreign agriculture data〉(1979) 33 kinds of prescriptions introducing, fertilizer title that they mainly adopt and the element such as the following table of being supplied:
Fertilizer title supply element
Calcium superphosphate P.Ca
Calcium phosphate
Mono-calcium phosphate
Ammonium nitrate N.S
SODIUMNITRATE
Ammonium sulfate
Saltpetre N.K
Calcium chloride Ca
Calcium sulfate
Gypsum (agricultural)
Repone K K.S
Vitriolate of tartar
Sal epsom Mg.S
Its weak point is the nutritive medium cost height by these formulation, as produces one kilogram of vegetables and need the expense of nutritive medium to close about 10 yuan of Renminbi approximately.
In view of above-mentioned weak point of the prior art the object of the present invention is to provide a kind of raw material low again plant growth nutrient fluid of cost that is easy to get.
Purpose of the present invention can realize by following measure: plant growth nutrient fluid is characterized in that the proportioning of this nutritive medium is following (by weight):
Ammonium sulfate 36～40
Ammonium nitrate 63～77
Double superhosphate 400～500
Vitriolate of tartar 55～65
Bitter salt 70～90
Waste gypsum 400～600
Borax 0.2～1.0
Zinc vitriol 0.2～1.0
Four anhydrous manganeses 0.2～1.0
Salzburg vitriol 0.2～1.0
Ferrous sulfate 0.5～1.5
The best proportioning of this nutritive medium following (by weight):
Ammonium sulfate 40
Ammonium nitrate 70
Double superhosphate 450
Vitriolate of tartar 60
Bitter salt 80
Waste gypsum 500
Borax 0.5
Zinc vitriol 0.5
Four anhydrous manganeses 0.5
Salzburg vitriol 0.5
Ferrous sulfate 1.0
Plant growth nutrient fluid of the present invention is a kind of composite inorganic fertilizer that includes nitrogen, phosphorus, potassium, calcium, magnesium, sulphur and various trace elements.The concise and to the point flow process of its preparation process is as follows: see accompanying drawing 1
Comprise in the prescription of the present invention that two portions composition is main component and ancillary component, main component includes fertilizer such as nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, ancillary component includes the necessary for plant growth various trace elements, and its concrete preparation process of nutritive medium of the present invention is respectively with granular double superhosphate Ca(H 2PO 4) 2H 2O(contains P 2O 5Be 21%) 400～500 parts, preferably 450 parts, and block waste gypsum CaSO 42H 2O400～600 part, preferably 500 parts, pulverize, make it all to be Powdered.Again with ammonium sulfate (NH 4) 2SO 4(nitrogen content is 20%) 36～40 parts, preferably 40 parts, ammonium nitrate NH 4NO 3(nitrogen content is 34%) 63～77 parts, preferably 70 parts; Vitriolate of tartar K 2SO 4(potassium content is 50%) 55～65 parts; Preferably 60 parts; Sal epsom MgSO 47H 2O70～90 part, preferably 80 parts; All add in the container, in it, add 1500 ml waters again, under 20～30 ℃ temperature and agitation condition, make it whole dissolvings.In addition with zinc sulfate ZnSO 47H 2O0.2～1.0 part, preferably 0.5 part; Manganous sulfate MnSO 44H 2O0.2～1.0 part preferably 0.5 part; Copper sulfate CuSO 45H 2O0.2～1.0 part, preferably 0.5 part; Ferrous sulfate FeSO 47H 2O0.5～1.5 part, preferably 1.0 parts and borax Na 2B 2O 710H 2O0.2～1.0 part, preferably 0.5 part adds in the another container, adds a small amount of boiling water to this container again, makes its whole dissolvings under agitation condition.Above-mentioned two kinds of solution and two kinds of powder are mixed at normal temperatures, and make it even by stirring.Survey its pH value with the PH test paper, can add the sodium bicarbonate adjustment, can add acetic acid adjustment, when pH value is between 6～7, be advisable if pH value is higher than 7 if pH value is lower than 6.Resulting suspension is has the nutritive medium of keeping the plant-growth effect, can use after adding 200 times of dilutions of water.
Embodiment 1
With 400 grammes per square metre calcium superphosphate Ca(H 2PO 4) 2H 2O(contains P 2O 5Be 21%) and 400 gram waste gypsum CaSO 42H 2O pulverizes respectively, makes it to be Powdered standby.With 40 gram ammonium sulfate (NH 4) 2SO 4(nitrogen content is 20%), 70 gram ammonium nitrate NH 4NO 3(nitrogen content is 34%) 60 gram vitriolate of tartar K 2SO 4(potassium content is 50%), 80 gram sal epsom MgSO 47H 2O all adds in the molten device, adds 1500 ml waters in it, makes it whole dissolvings under 20～30 ℃ temperature and agitation condition.Get 0.5 gram manganous sulfate MnSO again 44H 2O0.5 gram copper sulfate CuSO 45H 2O, 1.0 gram ferrous sulfate FeSO 47H 2O, 0.5 gram zinc sulfate ZnSO 47H 2O, 0.5 gram borax Na 2B 2O 710H 2O adds in another container, adds a small amount of boiling water in this container, makes its whole dissolvings under agitation condition.At normal temperatures above-mentioned two kinds of powder, two kinds of solution stirring are mixed, and make its pH value between 6.5 with acetic acid or sodium bicarbonate adjustment, the suspension of gained is plant growth nutrient fluid.
Embodiment 2
Repeat the operation of example 1, wherein double superhosphate 400 grams, waste gypsum 400 grams; Ammonium sulfate 38 grams, ammonium nitrate 65 grams, vitriolate of tartar 55 grams, sal epsom 75 grams; Manganous sulfate 0.3 gram, copper sulfate 0.3 gram, ferrous sulfate 0.5 gram, borax 0.3 gram, zinc sulfate 0.3 gram.
Embodiment 3
Repeat the operation of example 1, wherein double superhosphate 500 grams, waste gypsum 500 grams; Ammonium sulfate 40 grams, ammonium nitrate 80 grams, vitriolate of tartar 65 grams, sal epsom 85 grams; Manganous sulfate 1.0 grams, copper sulfate 1.0 grams, ferrous sulfate 1.2 grams, borax 1.0 grams, zinc sulfate 1.0 grams.
In nutrient solution prescription of the present invention, adopt ammonium sulfate and ammonium nitrate both to solve that no nitrobacteria can't make ammonia-state nitrogen (NH in the nutritive medium simultaneously 4) be converted into nitric nitrogen (NO 3) problem, reduced cost with sulphur ammonium instead of part ammonium nitrate simultaneously.Be to be an important channel that reduces cost again with waste gypsum instead of part agent product or agricultural calcium sulfate.Also have and utilize the local borax that abounds with to replace boric acid also can reduce cost.Adopt weak acid and weak base not only to control easily but also reduce cost to the adjustment of liquid PH value in addition.Make the cost of nutritive medium reduce greatly by above-mentioned a series of measures, as produce one kilogram of vegetables desired nutritional liquid expense and only close 1～2 jiao of Renminbi, reduce by 50～100 times than existing formulation cost.
