Description
Technical Field
The invention belongs to the field of fertilizers, and particularly relates to a special glutamic acid type fertilizer for sweet potatoes and a preparation method thereof.
Background
Amino acid can provide an organic nitrogen source, and plants can absorb the amino acid in a molecular state, and a large number of researches prove that the amino acid can improve the yield and the quality of crops, enhance the resistance of the crops and improve the ecological environment, so that the amino acid fertilizer is gradually accepted as a novel fertilizer.
Many studies show that L-glutamic acid affects the morphology of plant roots to change significantly, the plant roots branch in response to the stimulation of L-glutamate in vitro to form short and multi-branched roots, while the growth of primary roots is inhibited by L-glutamate in vitro, and the growth of main roots of Arabidopsis seedlings grown under aseptic conditions is significantly inhibited under the condition that the concentration of L-glutamic acid is 0.05-0.5mM [ Fillerur S, Walch-Liu P, GanY, Forde B G. L-glutamic acid has a very high specificity for this reaction, and the same concentration of the relevant amino acids, such as aspartic acid, glutamine, gamma-aminobutyric acid (GABA) and D-glutamic acid, has no effect. Cytological studies show that the mitotic activity of the main root tip of Arabidopsis thaliana is reduced by 36% and 60% in the meristematic region at 24h and 48h after the contact with L-glutamic acid, and the cell number of the meristematic region is correspondingly reduced by 17% and 50%, thereby indicating that the L-glutamic acid firstly causes the reduction of the mitotic activity of the main root tip meristematic region, and finally leads to the inhibition of the elongation of the main root. Similar reactions of L-glutamic acid for regulating root system morphogenesis also exist in other plant species, which shows that the influence of glutamic acid on root systems of many crops is great, but the reports of glutamic acid on root system growth of sweet potatoes are few.
In view of the cost of the glutamic acid, the waste utilization is a better way, for example, the glutamic acid is recovered from the waste liquid of producing the monosodium glutamate, the content of the glutamic acid in the waste liquid is the highest and accounts for 73 percent of the amino acid, the glutamic acid can be purified from the waste liquid of producing the glutamic acid, the recovery cost is low, and therefore, the cost of producing the glutamic acid fertilizer is reduced. The glutamic acid produced by Shaanxi Kangyuan chemical industry Limited liability company is low in price and free of toxic components, is matched with a phosphorus-potassium fertilizer, and is used for growth of sweet potatoes.
