Description
Technical field
The present invention relates to composite fertilizer's technical field, more particularly to a kind of corn special slow release composite fertilizer.
Background technology
Cultivation history about more than 470 year of the corn in China.Current China's sown area is only second at 300,000,000 mu or so
Paddy and wheat, the 3rd is occupied in cereal crops, the U.S. is only second in the world.The whole world torrid zone and Temperate Region in China are planted extensively, are
One important cereal.Taste is fragrant and sweet, can do various dish, and such as corn is ironed.It is also the primary raw material of industrial alcohol and liquor.
During corn planting, need to repeatedly it topdress, labour's input is larger, and corn belongs to long-stalked crop, and common fertilizer is applied
Enter because fertilizer efficiency is short in soil, jointing stage and ear period need to topdress, and recruitment is larger, and weather belongs to high-temperature condition during plantation,
Fertilizer loss is serious.
The content of the invention
The technical problem existed based on background technology, the present invention is proposed a kind of corn special slow release composite fertilizer, not only may be used
Good nutrient is provided for corn, and does not result in soil hardening, improves soil quality, while being delayed to nitrogen
Release, both ensured corn fruit nutrient demand, the later stage need not topdress again, reduce recruitment, time saving province's wealth is laborsaving.
A kind of corn special slow release composite fertilizer proposed by the present invention, its raw material includes by weight：Urea complex 25-35
Part, 18-28 parts of calcium magnesium phosphate, 10-20 parts of potassium dihydrogen phosphate, 60-80 parts of Chicken dung, 10-18 parts of bagasse, tapioca starch 15-
25 parts, 4-8 parts of trace-element fertilizer.
Preferably, urea complex is prepared using following technique：Chitosan, glacial acetic acid, water are mixed, heating stirring is cold
But, filter, add boric acid, heating stirring adds fusing urea, ricin, sodium polyphosphate and is well mixed, using hydroxide
Sodium regulation system pH value to 9-9.6, stirring in water bath, cooling obtains urea complex.
Preferably, urea complex is prepared using following technique：Chitosan, glacial acetic acid, water are mixed, 80-90 is warming up to
DEG C stirring 30-50min, cool down, filtering, add boric acid, be warming up to 60-70 DEG C stirring 40-80min, add fusing urea, castor-oil plant
Albumen, sodium polyphosphate are well mixed, using sodium hydroxide regulation system pH value to 9-9.6,50-60 DEG C of stirring in water bath 1-3h,
Cooling obtains urea complex.
Preferably, urea complex is prepared using following technique：By weight by 10-20 parts of chitosans, 3-6 parts of ice second
Acid, 150-200 parts of water mixing, are warming up to 80-90 DEG C of stirring 30-50min, cool down, filtering adds 4-10 parts of boric acid, is warming up to
60-70 DEG C of stirring 40-80min, adds 30-60 parts of fusing ureas, 5-15 parts of ricins, 1-2 parts of sodium polyphosphate mixing
Even, using sodium hydroxide regulation system pH value to 9-9.6,50-60 DEG C of stirring in water bath 1-3h, cooling obtains urea complex.
Preferably, trace-element fertilizer includes by weight：2-4 parts of borax, 1-2 parts of calcium monohydrogen phosphate, 1-2 parts of sodium metasilicate,
1-2 parts of EDTA chelates.
Preferably, EDTA chelates include by weight：0.2-0.8 parts of EDTA Chelated Manganeses, EDTA chelated zincs 0.1-0.7
Part.
Gained corn special slow release composite fertilizer of the invention can not only provide good nutrient for corn, and will not make
Into soil hardening, improve soil quality, the urea complex added in fertilizer can be according to corn nutrient demand feature, in jade
On the basis of nitrogen, phosphorus, potash fertilizer needed for rice growth course, further nitrogen is sustained, can both ensure that corn fruit is supported
Divide demand, while the later stage is not required to topdress, reduce recruitment, time saving province's wealth is laborsaving.
In urea complex of the present invention, the hydroxyl on chitosan generates complex compound with boric acid, is combined with urea, in soil
The activity of urase can effectively be suppressed, the utilization rate of urea is improved, and under the cooperation of sodium polyphosphate, carried out using ricin
It is modified, dissolution velocity is reduced, urea is difficult with soil erosion, and utilization rate is further improved；Urea complex cooperation calcium magnesium phosphate,
Potassium dihydrogen phosphate, the effect of EDTA chelated zincs, mutual degree of scatter are high, and grain forming is good, can improve corn to potassium and micro
The absorption of element zinc and utilization rate, increase the resistance of crop, improve the plumpness and sugariness of corn kernel, improve the product of corn
Matter.Chicken dung, bagasse, tapioca starch, borax coordinate simultaneously, can suppress the too fast release of fertile intragranular portion nutrient, reduction nitrogen, phosphorus,
Loss of the nutrients such as potassium, zinc in soil, makes fertilizer nutrient accordingly to be discharged according to the corn growth time, improves fertilizer nutrient
Utilization rate, and can effective improved soil structure, have more significant volume increase to corn, increase matter effect, decrease fertilizer throwing
The cost entered.
