Description
Technical field
The invention belongs to water planting romaine lettuce nutritive medium technical field, particularly a kind of nutrient solution prescription of romaine lettuce and compound method thereof.
Background technology
Present soilless culture is particularly in the nutrient solution prescription of water planting, and the acid-basicity adjustment of nutritive medium all relies on to be added liquid acids and meet the demands in the water, mainly be nitric acid, phosphoric acid or sulfuric acid.The benefit of using liquid acids is that it is acid strong, uses a spot of acid solution just can meet the demands; But also exist carry transportation inconvenient, be prone to the people produced shortcoming such as injury, especially for family type, miniaturized hydroponic system.
Therefore, to the family's balcony type hydroponic system that rises gradually, needing a kind of all be the nutrient solution prescription of solid fertilizer composition, and requires that fertilizer is cheap, compound method is simple.
Summary of the invention
The nutrient solution prescription and the compound method thereof that the purpose of this invention is to provide a kind of romaine lettuce.
A kind of nutrient solution prescription of romaine lettuce is characterized in that, the nutritive medium of this romaine lettuce comprises fertilizer and organic acid; Said fertilizer is made up of fertilizer A, fertilizer B and little fertilizer; Used fertilizer all is solid-state, and uses solid-state organic acid to regulate nutritive medium pH value, and the nutrient solution prescription of said romaine lettuce is following:
Fertilizer A: nitrocalcite 286g/T;
Fertilizer B: saltpetre 454g/T, sal epsom 163g/T, primary ammonium phosphate 87g/T;
Little fertilizer: EDTA iron 22g/T, boric acid 3.1g/T, manganous sulfate 2.2g/T, zinc sulfate 0.55g/T, copper sulfate 0.09g/T, ammonium molybdate 0.1g/T;
Organic acid: Hydrocerol A 410～460g/T, perhaps oxysuccinic acid 280～320g/T, perhaps tartrate 280～320g/T.
A kind of according to above-mentioned romaine lettuce nutrient solution prescription, carry out the compound method of nutritive medium, this method is following:
(1) according to the prescription requirement, take by weighing fertilizer A respectively, fertilizer B, little fertilizer, organic acid dissolves respectively with the normal temperature clear water, is made into mother liquor, and fertilizer A is made into mother liquor a, and fertilizer B is made into mother liquor b, and little fertilizer is made into mother liquor c, and organic acid is made into mother liquor d; Use preceding scene preparing nutrient solution in proportion;
(2), pour in the nutrient tank half of mother liquor a into stirring when the clear water in the nutrient tank (or bucket) during for half amount of needs volumetrical;
(3) after treating evenly, half of mother liquor b poured in the nutrient tank, stirred;
(4) after treating evenly, half of mother liquor c poured in the nutrient tank, stirred;
(5) continue in nutrient tank, to add clear water, wait to be added to when needing volumetrical 3/4 amount, remaining mother liquor a, b, c are added in the nutrient tank according to top order and working method;
(6) mother liquor d is added in the nutrient tank, continue to stir, until adding clear water to needed amount.
In the compound method of the nutritive medium of above-mentioned romaine lettuce, in the step (1), usually fertilizer A is made into 50 times of mother liquors; Fertilizer B is made into 50 times of mother liquors; Little fertilizer is made into 100 times of mother liquors; Organic acid is made into 100 times of mother liquors.
In the compound method of the nutritive medium of above-mentioned romaine lettuce, in the step (1), also can fertilizer A be made into 100 times of mother liquors; Fertilizer B is made into 100 times of mother liquors; Little fertilizer is made into 200 times of mother liquors; Organic acid is made into 200 times of mother liquors.
In the compound method of the nutritive medium of above-mentioned romaine lettuce, in the step (1), also can fertilizer A be made into 25 times of mother liquors; Fertilizer B is made into 25 times of mother liquors; Little fertilizer is made into 50 times of mother liquors; Organic acid is made into 50 times of mother liquors.
Beneficial effect of the present invention is: according to the nutritional need of romaine lettuce water planting, balance has been used macroelement, trace element; Simplified numerous and diverse program of preparation again according to the needs of actually operating; Nutrient solution raw materials is a solids package all, and nutritive medium is prepared at the scene, is more suitable for the requirement of family oriented cultivation.The present invention adopts solid peracid to adjust the prescription of nutritive medium potential of hydrogen, and used solid peracid is any one in Hydrocerol A, oxysuccinic acid, the tartrate, and the nutritive medium after the preparation is slightly acidic (about pH value=6.3).
Below in conjunction with embodiment the present invention is described further and utilizes solid organic acid adjustment nutritive medium process for preparation acid-basicity, the romaine lettuce mill water culture nutrient solution
