Abstract
The invention relates to a slow-dissolving-type fertilizer. The slow-dissolving-type fertilizer comprises the following raw materials in parts by weight: 60 to 100 parts of urea, 20 to 30 parts of sulfate, 20 to 30 parts of phosphate esterification starch, 10 to 20 parts of nitro humic acid ammonium, and 2 to 5 parts of gluconic acid. According to the slow-dissolving-type fertilizer, the chemical and physical environments of various nutritional elements in soil can be improved; the dispersing speed and the migration distance of the nutrients, such as nitrogen, phosphorus and potassium, in the soil are increased; the absorption and utilization to water and the nutrients by a root system are promoted.
Description
Technical field
The present invention relates to a kind of slow molten type chemical fertilizer.
Background technology
Along with the progress of science and the development of society, earth population is in continuous increase, in order to solve the grain demand grown with each passing day, the status of development in agricultural science and technology is more and more important, and in the development of agricultural science and technology, chemical fertilizer serves vital status, but for many years, chemical fertilizer in being manured into soil only has 20% ~ 30% to be utilized by this season Crop, and remaining chemical fertilizer, by soil fixing, forms a large amount of phosphoric acid salt, azotate deposition remains, destroy the crumb structure of soil, cause soil compaction, soil productivity declines, and cultivating property is deteriorated.Therefore the slow dissolubility chemical fertilizer of a kind of high-selenium corn utilization ratio of exploitation is badly in need of.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of slow molten type chemical fertilizer of high-selenium corn utilization ratio.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of slow molten type chemical fertilizer, comprises the raw material of following parts by weight: urea 60-100 part, vitriol 20-30 part, organic phosphate starch 20-30 part, nitro-humic acid ammonium 10-20 part, glyconic acid 2-5 part.
The invention has the beneficial effects as follows:
The present invention can improve the chemical physics environment of various nutritive element in soil; increase the adsorptive capacity on grogs surface; increase the adduction that various nutrition becomes material; nutrition protective belt can be formed rapidly at plant root after using; increase the velocity of diffusion of the nutrient such as nitrogen, phosphorus, potassium in soil and migration distance, promote root system absorbing moisture content and nutrient.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described slow molten type chemical fertilizer preferred value comprises the raw material of following parts by weight: urea 80-90 part, vitriol 25-30 part, organic phosphate starch 22-28 part, nitro-humic acid ammonium 12-18 part, glyconic acid 3-5 part.
Optimum value comprises the raw material of following parts by weight: 84 parts, urea, 26 parts, vitriol, organic phosphate starch 25 parts, nitro-humic acid ammonium 15 parts, glyconic acid 4 parts.
The organic compound that urea is made up of carbon, nitrogen, oxygen and hydrogen, also known as urea (with urine unisonance).Its chemical formula is CON

4o, molecular mass 60, International Nonproprietary Name is Carbamide.Outward appearance is white crystal or powder.It is the product after animal protein metabolism, is typically used as the nitrogenous fertilizer of plant.Urea synthesizes liver, be mammal discharge body in nitrogenous metabolites.
Urea is a kind of high density nitrogenous fertilizer, belongs to neutral readily avaiable fertilizer, also can be used for producing multiple compound manure.Not residual any objectionable impurities in soil, long-term application does not have detrimentally affect.Livestock industry can be used as the feed of ruminating animal.But in granulation, temperature is too high can produce a small amount of biuret, also known as biuret, has restraining effect to crop.China's regulation fertilizer urea Biuret Content should be less than 0.5%.When Biuret Content is more than 1%, can not do seed manure, seed manure and foliage fertilizer, other urea contents using the phase also should not too much or too concentrated.
Urea is organic nitrogenous fertilizer, the urase effect in soil, after being hydrolyzed into volatile salt or bicarbonate of ammonia, and could utilization absorbed by crops.Therefore, urea will be used before the need of the crop fertile phase for 4 ~ 8 days.
