Technical field
The present invention relates to agricultural fertilizer preparation field, the preparation side of a kind of Diammonium phosphate (DAP) seedling bed regulating acid agent
Method.
Background technology
Nitrogen, phosphorus, potassium are the big nutrients of plant necessary three, and nitrogenous fertilizer is a kind of fertilizer that agricultural application is most, and plant exists
Also needing to multiple middle trace element in growth course, calcium, magnesium, sulfur, ferrum, silicon, copper, zinc etc., nearly all protein has sulfur-bearing
Aminoacid, therefore sulfur suffers from important function in the 26S Proteasome Structure and Function of plant cell.Sulfur can promote that legume forms root nodule,
Participate in the formation of azotase；Element sulphur can improve aminoacid, protein content, and then promotes quality of agricultural product.Magnesium is that all are green
The indispensable element of color plant, because it is chlorophyllous composition, magnesium is also the activator of many enzymes.The catalysis of enzyme can be strengthened
Effect, helps lend some impetus to the metabolism of carbohydrate and the Repiration of crop, and magnesium has in the operating of plant neutralising phosphoric acid salt
Substantial connection, plays an active part in internal metabolic process, promotes crop synthetic vitamin A and vitamin C, thus is beneficial to improve fruit
And quality of vegetable, aminoacid is present in fertilizer as the smallest molecule constituting protein, has the feature being prone to absorbed by crops；
Also it is improved fertilising object disease resistance, improves the function of fertilising crop quality.Supplement plant essential amino acid, stimulate and regulate
Quick growth of plant, promotes plant growing healthy and strong, promotes the absorption to nutrient substance.Strengthen the metabolic function of plant, improve light
Cooperation use, promotes that root system of plant is flourishing, accelerates plant growing breeding.
Along with the development of market economy, large-scale agricultural mechanization development is increasingly faster, and granulated fertilizer is owing to having used the most
It is subjected to the favor of client.More there is complex manufacturing in existing granulated fertilizer, cause production for nutritional labeling to be ensured
The problem of high cost.
Summary of the invention
The technical assignment of the present invention is to provide the preparation method of a kind of Diammonium phosphate (DAP) seedling bed regulating acid agent.
