Abstract
The invention discloses a kind of enhanced slow-release fertilizer for concrete for plant growth, it is respectively that 20 ~ 40% phosphoamides, 10 ~ 25% diethanol amine, 10 ~ 30% zeolite powders, 12 ~ 20% feldspathic sandstones and 10 ~ 30% water stir by parts by weight, and granulate balling-up, diameter is between 1 ~ 6mm, then dry to constant weight, obtain enhanced slow-release fertilizer.Enhanced slow-release fertilizer disclosed by the invention can improve concrete strength and reduce its mix water requirement；Long-term release nitrogenous fertilizer, supplies plant growth；Raw material is easy to get, with low cost.
Description
Technical field
The present invention relates to a kind of enhanced slow-release fertilizer for concrete for plant growth, belong to novel environment friendly building materials technology field.
Background technology
It is, by the firm shaping of large-particle-size aggregate, to make plant by means such as sowing or earthing using binder materials to plant raw coagulation
In its growth inside, so as to reach the multiple green purpose of local ecological environment.To prevent from depositing cement mortar plugging hole gap, it is ensured that plant
The enough development spaces of root system, cement consumption is substantially less when concrete for plant growth is molded, concrete strength reduction.Meanwhile, to carry
For the nutrition composition needed for plant growth, appropriate fertilizer is added during concrete formation, this influences concrete strength to develop again.
Phosphoamide and diethanol amine not only can provide nitrogenous fertilizer for concrete for plant growth, while can reduce concrete formation needs water
Amount, improves concrete strength.Meanwhile, the nutrition composition that zeolite powder not only can be in adsorption fertilizer so that long-term sustained release is in plant, and
And its activated silica, aluminium component can be with clinker mineral aquation calcium hydroxide reaction, reduce inside concrete basicity, and improve coagulation
Native intensity.
The content of the invention
It is an object of the invention to provide a kind of enhanced slow-release fertilizer for concrete for plant growth, its phosphoamide discharged and
Diethanol amine can reduce concrete mixing water requirement and improve its intensity, and provide nitrogenous fertilizer for plant growth.While zeolite powder and arsenic
The porous and layer structure of sandstone can play a part of efficiency slow release again.
Technical scheme is as follows：
A kind of enhanced slow-release fertilizer for concrete for plant growth, is respectively 20 ~ 40% phosphoamides, 10 ~ 25% by weight fraction
Diethanol amine, 10 ~ 30% zeolite powders, 12 ~ 20% feldspathic sandstones and 10 ~ 30% water stir, and granulate balling-up, diameter between 1 ~
6mm, then dries to constant weight, obtains enhanced slow-release fertilizer.
Zeolite powder main component of the present invention is clinoptilolite, and specific surface area is between 260 ~ 300m2/kg；Feldspathic sandstone master
It is quartz, calcite and montmorillonite to want composition, and specific surface area is between 200 ~ 280m2/kg。
The present invention's has the prominent advantages that：
（1）Enhanced slow-release fertilizer disclosed by the invention can reduce concrete mixing water requirement and improve its intensity；
（2）Enhanced slow-release fertilizer disclosed by the invention can discharge nitrogenous fertilizer for a long time, supply plant growth；
（3）Raw material is easy to get, with low cost.
