Abstract
The invention discloses a rice special composite fertilizer. The rice special composite fertilizer is prepared by mixing raw materials yellow phosphorus slag, potassium chloride, calcium superphosphate, a silicate and plant straw at a certain ratio. The invention also discloses a preparation method of the rice special composite fertilizer. The preparation method comprises following steps: the yellow phosphorus slag is dehydrated and dried in the air, and is grinded; plant straw is cut into pieces, and a straw decomposing agent is scattered onto the plant straw pieces uniformly; potassium chloride, calcium superphosphate, the silicate, decomposed plant straw, and the grinded yellow phosphorus slag are mixed uniformly, and the mixture is subjected to pelleting; obtained pellets are dried at a temperature of 70 to 80 DEG C, are cooled and sieved, and are packaged so as to obtain the rice special composite fertilizer. The rice special composite fertilizer is capable of increasing yield of crops effectively, and improving lodging resistance and disease and insect resistance of crops. The yellow phosphorus slag is used as the raw material of the rice special composite fertilizer, and is taken fully advantages of; straw is also used as the raw material, so that pollute is reduced, waste is changed to be valuables, and cost of the rice special composite fertilizer is reduced.
Description
Technical field
The present invention relates to agriculture production Chemical Mixed Fertilizer, particularly a kind of compound fertilizer dedicated to paddy.
The invention still further relates to the preparation method of compound fertilizer dedicated to paddy.
Background technology
The solid waste of output when yellow phosphorus furnace slag is producing yellow Phosphorus by electric oven, 8 to 10 tons of yellow phosphorus furnace slags of the about output of 1 ton of yellow phosphorus of industrial every production, its main component is Calucium Silicate powder, the actual annual output yellow phosphorus furnace slag of China is approximately 6,000,000 to 7,500,000 tons at present, wherein small part is used for cement processed, brickmaking etc., most of discarded.
In Rice Production, using fertilizer is at present main mainly with nitrogenous fertilizer (urea), despises using of silicate, easily suffers disease and pest, lodging, underproduction situation.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
For addressing the above problem, the invention provides a kind of compound fertilizer dedicated to paddy.The necessary nutritive element of paddy growth is contained in this composite fertilizer, and nutrient is balanced.
The present invention also provides the preparation method of this compound fertilizer dedicated to paddy.
, be to be mixed according to a certain ratio by raw material yellow phosphorus furnace slag, Repone K, calcium superphosphate, silicate and straw, the weight percent of each raw material is:
Yellow phosphorus furnace slag 30%-40%;
Repone K 12%-22%;
Calcium superphosphate 10%-16%;
Silicate 5%-8%;
Straw surplus.
Described silicate is water glass or silicon-dioxide.
A kind of preparation method of compound fertilizer dedicated to paddy, comprise the following steps: yellow phosphorus furnace slag dehydration is dried, yellow phosphorus furnace slag after drying is ground, by after straw chopping, evenly apply the rotten agent of stalk, every mu of consumption 1-2kg, carry out stalk fast rotting, by Repone K, calcium superphosphate, silicate, the straw after rotting and the yellow phosphorus furnace slag after grinding mix evenly, by the mixture pelleting after mixing, under 70-80 ℃ of condition, dry, cooling again, sub-sieve, packing is made compound fertilizer dedicated to paddy.
Step is dried in described dehydration need be reduced to 1-3% by the water content of yellow phosphorus furnace slag.
Beneficial effect of the present invention: compound manure can make crop effectively increase production, also can improve the ability of lodging tolerance and the disease and insect resistance of crop, because compound manure of the present invention is used yellow phosphorus furnace slag, it is raw material, make full use of discarded yellow phosphorus furnace slag, with stalk, make fertilizer, not only reduce and pollute, also can turn waste into wealth, reduce the cost of compound manure.
