Description
Technical Field
The invention relates to the technical field of agriculture, in particular to a nutrient solution containing organic components and a preparation method thereof.
Background
The existing soilless culture nutrient solution formula is based on the mineral nutrient theory of the German chemist Libi (1803-1873), the theory indicates that plant root systems can meet the growth requirements of plants only by absorbing different types and amounts of mineral elements from soil solution, and the soilless culture nutrient solution is prepared by mixing inorganic compounds special for 13-15 nutrient elements including nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, boron, manganese, zinc, copper, molybdenum and the like according to different formula proportions.
Among the numerous soilless culture nutrient solution formulas, the nitrogen sources such as Knop (1865) classical water culture formula, snyder (1938) formula, rothanted (1952) formula, copper (1975) water culture formula and the like which are developed in the early stage only use nitrate nitrogen and do not add ammonium nitrogen; modern common nutrient solution formulas such as Hoagland nutrient solution formulas, japanese garden nutrient solution formulas, mountain Azakii nutrient solution formulas and rock-cotton planting drip irrigation formulas of Holland greenhouse crop research institute are also basically mainly composed of nitrate nitrogen, and ammonium nitrogen accounts for a small proportion.
The nitrate content in the nutrient solution is too high, so that the following problems occur in soilless culture production:
1) Antagonism to calcium and potassium in the nutrient solution and inhibition to absorption;
2) Nitrate can not be adsorbed by the matrix in the matrix cultivation, is easy to run off, causes waste and pollutes groundwater;
3) After the plant absorbs nitrate, nitrate nitrogen is converted into nitrite firstly and then ammonium nitrogen is converted through the catalysis of enzyme in the plant body, so that the nitrite content in vegetables and fruits is higher, and the nitrite is a cancerogenic substance and is harmful to human bodies;
4) Nitrate promotes rapid growth and cell generation of plants, and the plants are easy to overgrow, have poor disease resistance and stress resistance and influence the quality of crops.
A large number of researches and practical applications show that the plant can absorb inorganic mineral ions and also can absorb organic small molecules such as amino acid in complete molecular form, for example, glycine is added into the hydroponic nutrient solution, so that the growth of leaf vegetables is facilitated; adding a certain amount of organic matters such as coconut juice, banana or a certain amount of protein powder into the tissue culture nutrient solution; some novel simple soilless culture nutrient solutions can be added with organic amino acids, humic acid and the like, so that the quality of crops can be improved, but the addition is strong in randomness, irregular and cannot guarantee the effect.

Meanwhile, the nutrient solution still contains nitrate in calcium nitrate, so that the basic requirement of the crop on the nitrate is maintained.
The formula of the Japanese garden nutrient solution is as follows: 808mg/L (8 mmol/L) of potassium nitrate, 950mg/L of calcium nitrate tetrahydrate, 500mg/L of magnesium sulfate heptahydrate, 155mg/L, EDTA mg/L of ferric sodium salt, 20mg/L of boric acid, 2mg/L of manganese sulfate, 0.22mg/L of zinc sulfate, 0.05mg/L of copper sulfate and 0.02mg/L of ammonium molybdate. The amino acid content in the Japanese garden nutrient solution according to the invention is shown in Table 1.
