Abstract
The present invention discloses an environmental protection type cucumber nutrient solution capable of changing the form of nitrogen elements along with the change of environment temperature conditions, which belongs to the technical field of soilless culture. The compositions of the nutrient solution not only comprise the major elements of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and the like, but also comprise the microelements of ferrum, manganese, copper, zinc, molybdenum, boron and the like, and does not comprise pesticides or plant growth regulators. The nutrient solution has the advantages of scientific and reasonable formulation, comprehensive and abundant nutrient, convenient processing and use, safety for human and livestock, no pollution and no nuisance. The nutrient solution can meet the requirements of the growth and the development of cucumbers. Especially, the form of nitrogen elements is changed according to different seasons; on one hand, the absorption efficiency and the utilization efficiency of the nitrogen elements are improved; on the other hand, the cost of the nutrient solution is reduced. The nutrient solution completely conforms to the fertilizer safety standards of green foods.
Description
Technical field
The invention belongs to the cultivation technique without soil scope, particularly can change a kind of environmental protection type cucumber nutrient solution that changes nitrogen form with ambient temperature conditions.
Background technology
Cucumber is that people like one of main vegetable crop of food, and because of its area of origin warm moist, therefore higher relatively atmospheric moisture is easy to realize the good quality and high output of cucumber, also makes it become main one of vegetable variety of planting in the horticultural facility.According to statistics, 2003, China's facilities horticulture area reached 2,100,000 hm
2In northern horticultural facility, because of cucumber economic benefit height, its cultivated area has almost accounted for 30% ~ 40% of northern area facility cultivation area, as seen its critical role in facility cultivation.During the State's Ninth Five-Year Plan period, State Scientific and Technological Commission classifies national science and technology research project as with " research and development of cucumber batch production production stable high yield cultivation technique ", requires the cucumber annual yield by area to reach 25kg/m
2For realizing this goal, inventor place seminar uses cultivation technique without soil and carries out cucumber cultivation, and nutrient solution prescription is selected Japanese garden examination prescription and Huo Gelan prescription for use, finds in application, these two prescriptions in Beijing and the effect of surrounding area undesirable, simultaneously because of two kinds of NO that fill a prescription
3-N concentration is higher, and the nutritive medium cost up exists unnecessary nutritive medium NO on the other hand on the one hand
3-N is to key issues such as potential risk of underground water pollution (cultivation bed is porose, for unnecessary nutritive medium is discharged, well grows to guarantee cucumber root) and incompatibility northern area water quality characteristicses.Therefore, the cucumber cultivation technique without soil can big area be promoted, at first must reduce the nutritive medium cost.Secondly, consider environmentAL safety; Once more, also to easily cause substrate pH these reality that raise, propose that research is fit to the northern area water quality characteristics and be the economical and practical environmentally friendly cucumber soilless culture nutrient fluid of aim to reduce nutritive medium cost and production system safety at the northern area water quality characteristics.
Summary of the invention
The purpose of this invention is to provide a kind of environmental protection type cucumber nutrient solution, described cucumber nutrient solution with nutritive element by the mole concentration ratio is: K
+: Ca
++: Mg
++: NO
3 -: SO
4 -: P: NH
4 +: Fe
++: Mn
++: B: Zn
++: Cu
++: Mo=8: (2～3): (1～2): (10～12): (3.5～4.5): 2: (3～4): 0.05: 0.01: 0.05: 0.0008: 0.0003: 0.0001 is formulated; It is characterized in that: in this composition with NH
4-N partly replaces NO
3-N promptly selects urea that acid amides attitude N is provided, and ammonium sulfate provides NH
4-N replaces bismuthite with this, makes the matrix after nutritive medium waters keep slightly acidic; And select DTPA-Fe that ferro element in the trace element is provided.
Beneficial effect of the present invention is at NO in the existing cucumber soilless culture nutrient fluid prescription
3-N concentration height, easily residual, the contaminated soil environment, the shortcoming that cost is high, in this nutritive medium except that containing major elements such as nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, also contain trace elements such as iron, manganese, copper, zinc, molybdenum, boron, do not contain agricultural chemicals and plant-growth regulator, scientific formulation, reasonable, comprehensive nutrition, abundant, can satisfy the needs that cucumber growth is grown,, improve the efficient that absorbs of N element on the one hand especially by the change of Various Seasonal nitrogen form, on the other hand, reduced the nutritive medium cost; The processing of this nutritive medium is easy to use, pollution-free to the person poultry safety, nuisanceless, meets the fertilizer safety standards of green food fully.
Embodiment
The invention provides a kind of environmental protection type cucumber nutrient solution.Described cucumber nutrient solution with nutritive element by the mole concentration ratio is: K
+: Ca
++: Mg
++: NO
3 -: SO
4 -: P: NH
4 +: Fe
++: Mn
++: B: Zn
++: Cu
++: Mo=8: (2～3): (1～2): (10～12): (3.5～4.5): 2: (3～4): 0.05: 0.01: 0.05: 0.0008: 0.0003: 0.0001 is formulated; In this composition with NH
4-N partly replaces NO
3-N promptly selects urea that acid amides attitude N is provided, and ammonium sulfate provides NH
4-N replaces bismuthite with this, makes the matrix after nutritive medium waters keep slightly acidic; And select DTPA-Fe that ferro element in the trace element is provided, therefore increase NH at low temperature season
4The ratio of-N, high temperature season are used acid amides attitude N instead, as Japanese garden examination general formulation NO
3-N and NH
4The ratio of-N is 16: 1, utilizes this prescription can make the two ratio become (10～12): (3～4), low temperature season NH
4-N can account for 50% of nitrogen consumption, and (being the molar concentration rate of nutritive element) uses NH simultaneously
4-N replaces amidonitrogen, overcomes the absorb efficient of low temperature season because of the low N of influence of urease, and high temperature season is used acid amides attitude N instead.Cucumber nutrient solution can be changed with ambient temperature conditions change nitrogen form.
According to cultivation season, according to the molar concentration rate of above-mentioned nutritive element, on the basis of Japanese garden examination prescription, reduce the consumption of nitrocalcite and saltpetre, not enough nitrogen is replaced by ammonium sulfate or urea.The concrete prescription of cucumber nutrient solution is formed as shown in table 1.
Specifically with preparation 1m
3Nutritive medium be that example is illustrated the present invention: in liquid storage tank or receiver, put into 0.5m earlier
3Water, take by weighing 607g saltpetre then successively, treat that it dissolves fully after, take by weighing the 272.1g potassium primary phosphate again, stir, make its dissolving, add water to 0.7m
3, low temperature season then takes by weighing 196-294g ammonium sulfate and 369.8-409.5g sal epsom in this way, stirs and makes its dissolving, adds water to 0.9m
3, add nitrocalcite 472-708g at last, fully after the stirring and dissolving, add DTPA-Fe 15ml more successively, manganous sulfate 2g, boric acid 3g, zinc sulfate 0.22g, copper sulfate 0.05g, ammonium molybdate 0.02g adds water to 1m at last
3Behind temperature recovery, generally since mid or late April, change the ammonium sulfate in the above-mentioned fertilizer into urea, the consumption of urea is 95.4-120g, other fertilizer amounts are constant substantially.
