Description
The invention belongs to a kind of durable inorganic composite fertilizer with trace elements and manufacture method thereof of vitreous state, this fertilizer is the necessary nutritious fertilizer of plant.
The present minimum plant nutritive element fertilizer that is a kind of vitreous state by the disclosed a kind of durable inorganic composite fertilizer with trace elements of foreign patent, it has slowly-releasing, safety, economy, characteristics easily.As foreign patent WO83/02939; US4,334,908; US3,930,833 phosphate glasses of being reported that contain nutritive element belong to the little fertilizer of this class vitreous state exactly.Above-mentioned patent all is with P
2O
5Formation agent as parent glass, and micro-metals just enters the glass network structure with intermidate oxide, so the various micronutrient levelss of this phosphate glass in little fertile composition can not be very high, therefore to lacking serious soil and the crop of nutrient substance, it renders a service not enough.In addition, phosphate-based glass fertilizer is founded in the process crucible is corroded seriously, so the fertiliser production cost is higher.
The objective of the invention is to overcome above-mentioned shortcoming, a kind of low cost of manufacture is provided, micro-total content height, and have efficient volume increase and improve the durable inorganic composite fertilizer with trace elements of crop quality effect.
The present invention is a kind of durable inorganic composite fertilizer with trace elements of vitreous state, it is characterized in that, basic glass is to adopt borate glass, promptly adopts B

3In glass is formed also is the essential micronutrient element of a kind of plant, and therefore the total amount of the trace element in the inorganic composite fertilizer with trace elements of the present invention can be higher than 65%.
Above-mentioned Chemical Composition can be done to adjust arbitrarily in its composition scope according to the needs of soil and plant.Therefore can be according to the synthetic a series of single and comprehensive durable inorganic composite fertilizer with trace elements that contain various micronutrient elements of prescription of the present invention.
The basic recipe scope of durable inorganic composite fertilizer with trace elements of the present invention is (counting by weight percentage): quartz is 5～13%, and feldspar is 0～15%, and slag is 7～30%, and borax is 30～61%, and trace element oxides is 0～26%.The present invention utilizes natural matter (ore) and artificial waste material to make raw material, and slag wherein is to adopt solid-state trade waste, as industrial residue and ore powders such as blast-furnace slag (shrend) and perlite slags, forms the raw material of parent glass.So not only opened up the new way of waste resource regeneration, and in the glass fertilizer component, introduced a part of useful element, as K, Ca, Mg, Si etc., to increasing production and improving crop quality and also play effective function plant-growth.
The manufacture method of durable inorganic composite fertilizer with trace elements among the present invention, it is formation raw ore powder with basic glass, industrial residue, the various trace element oxides that borax and plant are required, according to a certain ratio behind the uniform mixing, send in the smelting furnace and found, pass through high-temperature chemical reaction, make MO, Mn, Zn, Cu, Fe goes with the network structure that ionic state enters into borate glass, glass melting temperature is 1100～1280 ℃, the vitreous state fertilizer that melts is through shrend, oven dry is reprocessed levigate, make pulverous durable inorganic composite fertilizer with trace elements, the fineness scope of fertilizer is 100～300 orders.
Durable inorganic composite fertilizer with trace elements of the present invention has low water solubility (water-soluble rate is 0.6～2%), with high solubility in citric acid (the molten rate of Chinese holly is 68～97%), therefore can under the effect of plant root hair excretory weak acid, slowly release, by ion-exchange, progressively absorbed by plant root, therefore have long-acting characteristic, play significant production-increasing function.
Contain needed micronutrient element of various crop growthing developments and the elements useful such as grain, cotton, melon and fruit, vegetables in the fertilizer of the present invention to plant growth, the nutrition of its fertilizer is more complete than existing trace element fertilizer, therefore in whole growth phase of crop, fertilizer of the present invention can replenish at any time effectively to the needed various nutritions of plant, it can also promote the absorption of N, P, K fertilizer simultaneously, gives full play to the fertilizer efficiency effect of N, P, K fertilizer.
In addition, that the present invention also has is safe, economical, long-acting, use conveniently, fertilizer material convenient sources, low cost of manufacture, advantage such as production method is simple, and operation is few, and is easy to operate, and facility investment intensity is little.
Fertilizer of the present invention was once made repeatedly field test on crops such as paddy rice, cotton, fruit tree, all obtain significant volume increase and the effect of increasing income, and its data see the following form:
