Description
Technical field
The invention belongs to the technical field of fertilizer, a kind of phosphorous Liquid Fertilizer of modification and preparation method thereof is particularly related to.
Background technique
China is a large agricultural country, populous, in order to increase grain yield, one of effective means be exactly by means of
Fertilising.Fertilising is all the organic fertilizer limits throughput based on chemical fertilizer and organic fertilizer in world wide at present, and application is by very
Big limitation, moreover, its fertilizer efficiency is unobvious；The long-term excessive or unreasonable application of chemical fertilizer, causes each nutritive proportion in soil
Imbalance, causes the hardened of soil, reduces the utilization rate of fertilizer and the quality of agricultural product, also, the production of chemical fertilizer and
Application can also cause atmosphere and water resource pollution, and very big destruction is caused to environment.
Phosphorus is one of the three elements of crop nutrition, and crop is intracorporal next in number only to nitrogen and potassium, typically constitutes from dry matter weight
0.2-1.1%.Phosphorus is crop nucleic acid in vivo, phosphatide, the component for planting the living matters such as element, enzyme, vitamin, is carry important
Function.When crop lacks phosphorus, neoblast forms difficulty, and crop growth is obstructed, and it is short and small to show as plant, slow growth, point
Tiller is few, and root system is few, depauperation, and leaf color is dark green matt or thin, more lignifyings in aubergine stem, spends less, fruit is few, and fruit is not
It is full, grain heavy and light, mature evening.The application of phosphate fertilizer can increase crop yield, improve crops quality, accelerate cereal crops point
Tiller and promotion full seed；Promote yielding positive results for cotton, melon, solanaceous vegetables and fruit tree, improves fruiting rate；Increase sweet tea
The sugar of dish, sugarcane, watermelon etc.；Improve the oil content of rapeseed.It can be divided by the dissolubility of phosphate fertilizer: water soluble phosphorous fertilizer, weak acid
Dissolubility phosphate fertilizer, difficultly soluble phosphatic fertilizer etc., common phosphate fertilizer have calcium superphosphate, calcium magnesium phosphate, ground phosphate rock.
Currently, in agricultural production, the phosphate fertilizer imposed in crops soil only has very small part to be utilized by crops, greatly
About 80% available phosphorus is fixed by high valent cationics such as Ca, Mg, Fe, Zn, Al in soil, insoluble phosphorus is formed, in rain
Water washes away lower runoff and constantly enters water body, and the accumulation of P elements necessarily leads to the raising of phosphorus concentration in runoff in soil, thus shape
It is polluted at the phosphorus of large area.For a long time, it is enriched largely fixed invalid phosphorus in soil, on the one hand causes fertilizer in soil
A large amount of wastes, on the other hand destroy the crumb structure of soil.
Summary of the invention
The object of the present invention is to provide phosphorous Liquid Fertilizers of a kind of modification and preparation method thereof, solve in the prior art contain
Phosphatic manure insoluble phosphorus easy to form and the problem of cause it that cannot be absorbed by crops and destroy soil texture.

Influence of 2 different disposal of table to tomato physical signs and yield
As can be seen from Table 2, the phosphorous Liquid Fertilizer processing of the modification prepared using the embodiment of the present invention one to embodiment three
Tomato afterwards, the organic acid content that is averaged is about 0.46%, and average Vc content is about 44mg/100g, and average fruit weight is about
220g, average soluble solid content is about 3%, and single plant yield is about 3.1Kg；Therefore, the embodiment of the present invention one is to reality
It applies the average organic acid content of the resulting tomato of tomato after the phosphorous Liquid Fertilizer of modification prepared by example three is handled, average Vc content, put down
Equal single fruit weight, average soluble solid content, single plant yield are apparently higher than other three control treatments, this makes tomato
Grade and mouthfeel are apparently higher than other three control treatments, also, the modification that the embodiment of the present invention one is prepared to embodiment three
The harvest date of tomato is advanced by 10-13 days after the processing of phosphorous Liquid Fertilizer, this illustrate the phosphorous Liquid Fertilizer of modification of the invention to kind
The effect of being significantly improved of the quality and yield of eggplant.
To sum up show that the phosphorous Liquid Fertilizer each component of modification that the embodiment of the present invention one is prepared to embodiment three cooperates
The quality of tomato can be significantly improved, biggish income can be brought to numerous vegetable growers.
Compared with prior art, the beneficial effects of the present invention are: the phosphorous Liquid Fertilizer of modification of the invention is first in acid water
Under system, humate and phosphorylation agent are subjected to phosphating reaction, the Long carbon chain of humic acid molecule is cut and is filled
Divide graft modification, enrich the type and quantity of functional group, improve sequestering power, has powerful surface energy and cation
Exchange capacity when mixing with a great number of elements, moderate-element and microelement, not only has activation, conversion and movement etc. more in phosphate fertilizer
Weight effect, moreover it is possible to which the high valent cationic in absorption and complexing soil, be conducive to crops fully absorbs utilization, further
The utilization efficiency of phosphate fertilizer and humic acid is improved, phosphate fertilizer does not react with metal ion, also not antagonism, avoids to form indissoluble
Property phosphate fertilizer, alleviates environmental pollution, reduces the destruction to soil texture；Meanwhile improving the wadding of humic acid and metal ion
It is solidifying, improve resistance to hard water.The raw materials used in the present invention is environmentally friendly, and process flow is short, and preparation method is simple, resulting
Modified phosphorous Liquid Fertilizer can be improved the utilization rate of fertilizer, be more advantageous to the absorption and utilization of crop.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
