Description
Technology
The present invention relates to a fertilizer and a preparation method, in particular for the preparation of an environmental friendly fertilizer and
Methods and techniques. Such conventional NPK fertilizer in addition to containing elements, but also contains zeolite, sepiolite,
Active additives and ingredients added rare earth nitrate, etc., in addition to conventional fertilizer with a high-efficiency increasing effect
But also improve the soil, moisture moisture, water storage fat, long-acting release and other functions, for farmers
Environmentally friendly fertilizer industry, the international patent classification is proposed for Int.Cl7 C05G 3/00。
BACKGROUND
Mainly in the domestic market of existing fertilizer nitrogen, phosphate, potash-based, water-soluble fertilizer available belong.
These fertilizers are prevalent in the course of the following deficiencies: (1) the low utilization rate of fertilizer: Its because of that fertility
Released quickly, crops do not have enough time to absorb, so fertilizer utilization rate; For nitrogen,
Because nitrogen highly volatile, and its lower fertilizer utilization; (2) impact of natural conditions: In the drought
Or without irrigation and fertilizer, water soluble fertilizer available for this fertilizer is difficult to play; And when before rain, rain
Quarter or centralized irrigation fertilization, soil moisture content is too high, this water-soluble fertilizer available and easy to produce cream
Lost, resulting in waste; (3) fertilization is difficult to grasp: When a fertilizer too high, often causing heartburn
Seedlings, crop lodging leggy or generate such phenomena; if fertilizer is too low, they can not meet the entire crop growing
Term needs; while graded dressing, not only to spend a lot of labor and money, and many fertilizers discomfort
Together as a fertilizer, even sub-sub-dressing may not achieve the desired results. In addition, from the agricultural ecological environment
Perspective, these conventional fertilizer in farmland after only a part absorbed by crops, and the rest waste
Out. To nitrogen, for example, under normal circumstances is not plants use nitrogen more than 50%, some even up to
To 80%, is not so much a nitride Most plants use by farmland drainage and surface runoff carrying
Brought to the groundwater, or surface waters, causing eutrophication, resulting in serious environmental pollution problems.
On the other hand, it is inefficient fertilizer, hours Depletion, farming missed, wasting a lot of money.
...
According to the Chinese Academy of analysis data (see ref: China Agricultural Science and Technology, 1999,1) Table
Description: Several large agricultural country in the world, the Chinese unit area last year the average amount of chemical fertilizer is the highest,
Namely, Russia, Canada and the United States 9.00,4.35 and 2.42 times, while the average per kg of fertilizer
Productivity is the lowest, namely Russia, Canada and the United States 22.7%, 29.4% and 26.7
%. At present the total water consumption of agricultural water 70%, while the utilization of irrigation water is only 30 ~
40%, less than the utilization of some of the world's developed countries, 1/2, the shortage of water resources and water resources
Waste co-exist, so the development of China's water-saving agriculture has great potential, and has great strategic significance.

Together, mainly considering the distribution of mineral resources in different areas can choose different types of zeolite zeolite
As a fertilizer raw material for the production, reduce costs and more advantageous application. The average particle size of the zeolite
Designed to be 0.5-45 microns, the main consideration is that when the average particle size less than 0.5 microns, the zeolite material into
The higher the average particle size greater than 45 microns, the dispersion uniformity of the zeolite is too low, can not fully play its
Function. This design also means that outside the range of the selected zeolite particle by the same applies to the present invention. Boil
Stone is a hydrous calcium, sodium, and barium, potassium aluminum silicate minerals. It has a unique internal structure:
By the silicon-oxygen tetrahedron and alternative aluminum-oxygen tetrahedron as the basic structural unit of silicon-oxygen tetrahedron and tetrahedral aluminum
Body component units and then progressively ring, double ring, ring and cage diverse, constituted mainly of three-dimensional space frame-like structure
Polyhedron made crystal. Zeolite crystals inside there are lots of orderly, uniform size, consistent with each other
And connected to the outside through the hole and opening (pore size generally 0.3 ~ 1nm). These zeolite cavities and channels
Crystals suction drainage is important. Zeolite crystals grids in the amount of water available and with the outside temperature
Humidity change, but this does not affect the internal structure of the crystal. Therefore, when the environmental conditions change
When water is often the zeolite can be freely discharged or re-inhaled, does not affect or damage the crystal structure of the zeolite.
As the zeolite of this special structure, designed to be used in the present invention may have the following fertilizer purposes: (1)
Soil: zeolite ion exchange with good and unique porous structure, can promote soil from
Ion exchange, improve soil retention of nitrogen, potassium and calcium and nutrients the ability of the modified acid soil or alkaline soil
Has a significant effect soil; (2) moisture absorbent: Zeolite in the case of small air humidity can be extremely
Effectively absorb moisture from the air and moisture can be maintained well within its pores and not lost; in
Continuous drought period, this exotic water and absorb water retention capacity is very favorable for crop growth, but also
Helps to reduce irrigation, water saving; (3) water reservoir fat: As the porous structure of the zeolite, which can be
Fertilizers molecular inhalation own hole, played the role of water and fertilizer. Therefore, the application of this invention can ensure fertilizer
Little or no loss of water and fertilizer loss, one can improve efficiency, on the other hand to avoid adverse environmental or water
Pollution of the body, the environment-friendly; (4) as a slow release agent: Zeolite feature can make the entire life
Long season slowly release nutrients required by plants, it can be used as fertilizer release agent, its role and priorities
Point is: ① to increase the efficiency of plants to absorb fertilizer; ② significantly reduced by leaching, fixation and decomposition made
Into fertility loss; ③ avoid direct contact with fertilizer plants or seedlings and burn plants or damage seedlings;
④ the fertilizer is not volatile, to ammonia, not pungent, no caking, easy to use; (5) In summary, the use of this
Invention can reduce the amount of fertilizer fertilizer, reduce the cost, while agriculture and eco-friendly.
