Description
Technical field
The present invention relates to water-soluble fertilizer technical fields, and in particular to a kind of water-soluble fertilizer for improving soil property and its preparation side
Method.
Background technology
China is large agricultural country, and fertilizer is one of essential means of agricultural production articles for use.Fertilizer is the Major Nutrient source of crops,
Crops absorb nutrition to meet the growth and development of plant by root cell film, many diseases of plant be all in default of
Caused by nutrition.
Water-soluble fertilizer mainly has the macroelement fertilizer and the mixing of single or various trace elements based on nitrogenous, phosphorus, potassium
Fertilizer.Water-soluble fertilizer passes through water dissolution or dilution, exists in the form of ionic state or small molecule, greatly improves crop to water-soluble
The absorptivity of fertilizer improves the undesirable illness of plant nutrient.
Count according to investigations, China by heavy metal pollution cultivated area up to 20,000,000 hectares, account for national total area under cultivation
1/6.China's grain contaminated by heavy metals every year on average causes direct economic loss more than 20,000,000,000 yuan up to 12,000,000 tons.Root
According to counting in recent years, China's Cd-polluted farmland area reaches 280,000 hectares, produces the exceeded agricultural product quantity of cadmium per year more than 1,500,000 tons
(Luo Qiong, Wang Kun, Xu Jingbo, Chen Guanghui：" China's cadmium pollution present situation, harm, source and its production measure ",《Agriculture of Anhui
Science》2014[30]).Cadmium is one of most strong heavy metal of toxicity, and cadmium not only influences the growth and development of rice, leads to rice yield
And quality decline, and into food chain or the respiratory tract of people, danger can be entered in plant interior accumulation and by polluting air
Evil human health.
At present, absorption and enrichment of the crop particularly rice to cadmium in heavy-metal contaminated soil environment are reduced, that takes arranges
There are mainly three types of applying：First, heavy metal is directly removed from soil；Second is that change the occurrence patterns of heavy metal in soil；Third,
Spray blade face resistance control agent.However, the first measure is larger because of fund needed for engineering reparation, it is difficult to is widely applied；Second
Kind measures on soil destruction is heavier, and necessary trace element also precipitates in soil, so as to cause nutrient deficiency；Third
Kind sprays blade face resistance control agent and certain influence is often generated on the quality and yield of rice, therefore, a kind of novel improvement soil of exploitation
The water-soluble fertilizer of matter, for those in the field, then more realistic meaning.
Invention content

It obtains, will be added in extraction kettle after the corn straw smashing dried, control extraction temperature, pressure and time, extraction is completed
The blowing from separating still afterwards obtains maize straw extracting solution.
Preferably, the water-soluble fertilizer of a kind of improvement soil property, the temperature of the extraction kettle is 40~65 DEG C, extraction pressure
Power is 30~65MPa, and extraction time is 0.5~3.0h.
Preferably, the water-soluble fertilizer of a kind of improvement soil property, the temperature of the separating still is 40~65 DEG C, and pressure is
6~18MPa.
Preferably, the water-soluble fertilizer of a kind of improvement soil property, the pollen are dandelion pollen.
A kind of preparation method for the water-soluble fertilizer for improving soil property, by load weighted maize straw extracting solution, pollen, chitosan
After being mixed with water, 30~50min is stirred at a temperature of 60~70 DEG C, white-rot fungi spore suspension is added, with 80~100r/
The rotating speed of min stirs 10~15min to being uniformly mixed, and is put into drying machine is dried after 5~6h of standing at room temperature, you can
To the water-soluble fertilizer for improving soil property.
Compared with prior art, the present invention has following advantageous effect：The present invention can not only reduce plant heavy metal
The absorption and enrichment of cadmium element, can also be evenly distributed in plant root soil by water-fertilizer integral, be effectively promoted agriculture
The growth of root of the crop, stem, leaf and fruit, meets demand of the breeding time plant to various nutrients, promotes the growth of plant, improves
The yield of crop increases soil property content of organics, improves soil property.The preparation method of the present invention is simple and efficient, is of low cost, has
There is higher commercial exploitation.
