Description
Technical field
The present invention relates to technical field of fertilizers more particularly to a kind of composite liquid fertilizer and preparation method thereof.
Background technique
Crops not only need the big main nutrient elements of N, P, K tri- during the growth process, it is also necessary in Mg, Ca, S, Si etc.
Secondary element.Element silicon is the Four Plants nutrient after nitrogen, phosphorus, potassium, is the required of grass family and root block class crop
Nutrient.Modern agriculture needs balance fertilizing, in largely application nitrogen, phosphorus, after potash fertilizer, scientifically and rationally apply magnesium, silicon fertilizer and its
His microelement, not only can be improved crop yield and quality, can also improve the ecological environment and the problem of soil acidification.
Magnesium elements are that a kind of important moderate-element, the shortage of magnesium elements necessary to plant growth will lead to crop photosynthesis
Decline, protein synthesis are reduced, so as to cause crop yield and quality decline.Existing salt lake, which produces potassic-magnesian fertilizer, has K, Mg, S nutrition
Element is a kind of fertilizer of fully natural green containing magnesium, potassium, magnesium nutrition element can be provided for crop, be applied to extensively avoid chlorine grain with
The industrial crops such as industrial crops, such as vegetables, fruit tree, tobacco, tealeaves and flowers.However, existing salt lake, which produces potassic-magnesian fertilizer, is free of Si
With Ca nutrient, the application of single potassic-magnesian fertilizer be easy to cause the unbalance of Nutrient Elements in Soil, causes to measure member in Ca, Si etc.
The deficiency of element, is unfavorable for the growth and volume increase of crops.Meanwhile existing potassic-magnesian fertilizer is solid, be unfavorable for crops absorption and
The operation of fertilising person.
The substances compound tense such as liquid potassic-magnesian fertilizer and solid is phosphorous, calcium, silicon, with the increase of phosphorus, calcium, silicone content, Liquid Fertilizer
The suspension of material is deteriorated, it may appear that layering.Therefore, potassic-magnesian fertilizer is compounded to form compound fertilizer with other elements there are technical
Difficult point.
Summary of the invention
The main purpose of the present invention is to provide a kind of composite liquid fertilizers and preparation method thereof, in the prior art to overcome
It is insufficient.
For achieving the above object, present invention employs following technical solutions:
The embodiment of the invention provides a kind of preparation methods of composite liquid fertilizer, comprising:

Potassic-magnesian fertilizer is added to the water dissolution, adds the substance, the substance containing calcium constituent, the object containing element silicon of phosphorus element-containing
Matter and sodium carboxymethylcellulose, stirring, obtain the second suspension；
First suspension and the second suspension are mixed and stirred for, the composite liquid fertilizer is obtained.
The embodiment of the invention also provides the composite liquid fertilizers of the preparation method preparation by the composite liquid fertilizer.
Compared with the prior art, the beneficial effects of the present invention are:
Composite liquid fertilizer of the invention solves existing potassic-magnesian fertilizer nutrient list containing multiple elements such as Mg, Ca, Si, P
One, not the problem of not being able to satisfy crop growth needs and soil acidification.The composite liquid fertilizer can be same for plant growth and volume increase
When provide required for the nutrients such as potassium, magnesium, silicon, calcium, phosphorus.Composite liquid fertilizer is easy to be absorbed by crops, is that one kind has
The compound potassic-magnesian fertilizer product of development prospect.
Contain filler, such as carclazyte, palygorskite in first suspension of the invention, can not only be provided for liquid fertilizer very well
Suspension, keep liquid fertilizer not stratified, and a large amount of element silicon can be provided, to be easy to potassic-magnesian fertilizer and other elements
It is compounded to form composite liquid fertilizer.
