Abstract
The present invention relates to a seed manure specially for corn and its production process. The seed manure contains nitrogen fertilizer, phosphate fertilizer, and potash fertilizer. The raw material of the phosphate fertilizer is calcium superphosphate and monoammonium phosphate with the weight parts of 448 and 153.8, the raw material of the potash fertilizer is potassium sulfate and potassium chloride with the weight parts of 60 and 30, the raw material of the nitrogen fertilizer is ammonium nitrate, ammonium sulfate and monoammonium phosphate, wherein the weight parts of the ammonium nitrate and ammonium sulfate are all 76.9, the nitrogen fertilizer also contains 156.4 weight parts of humic acid. The production process includes the steps of smelting ammonium nitrate, ammoniating, revolving and pelletizing, adding calcium superphosphate, potassium sulfate and humic acid. The seed manure specially for corn of the invention can promote the growth of corn seedling root system, and provide corn seedling with sufficient nutrients.
Description
Technical field
The present invention relates to corn seed fertilizer and production technique thereof, particularly a kind of corn seed manure specially and production technique thereof.
Background technology
Plant is planted based on corn by China the Northeast, and the corn seeding area accounted for 25.4% of national corn seeding area in 2003, reached 611.4 ten thousand hectares, and especially there is the title of " Corn Belt of China " at the middle part, Jilin Province.Since the eighties, a large amount of corns export states such as Japan, for foreign exchange has been earned by country, have become one of staple commodities of this province foreign trade outlet.
But the promote mainly fertilizer variety of past at corn is general fertilizer of 15-15-15 and 16-12-12 corn fertilizer, and composite fertilizer's nitrogen phosphoris and potassium fertilizer ratio of 15-15-15 is fixed, and causes waste or single nutrient quantity not sufficient when using easily.Particularly since calendar year 2001, agricultural-food are made a price reduction significantly, and farmers' income reduces, require using of fertilizer reasonable more economically, avoid irrational fertilising to cause economically loss, only rely on general fertilizer and be difficult to exploit market at all, satisfy market the more requirement of Gao Gengxin of composite fertilizer.
Simultaneously, a kind of release of fertilizer formula not only will be considered basic nutrient situation of soil and crop alimentary characteristic, and local peasant's the fertilising custom and the mode of production that should the zone also should be to influence the essential factor that fertilizer variety is chosen.The Northeast's planting system be 1 year one ripe, frostless season is short, is generally 120-150 days, annual farming mainly concentrates on the 5-10 month period.Peasant planting Zea extensive management, fertilizer applied in the spring season is after planting no longer carried out other cultivation management measures except that using mid-term in growth the weedicide weeding, most of peasant household does not topdress or topdresses less, add that blue or green in recent years strong labor force goes out to do manual work more, the labor force that actual participation is produced is limited, is more prone to time saving and energy saving single fertilization traditionally in fertilising.Though habits fertilization is fit to the characteristics of fertile characteristic of the need of corn and northeast soil, but in view of the single fertilization degree of depth all more than 10 centimetres, and need add the nitrogen sustained release drug time of releasing in order to prolong nitrogen, early stage is undeveloped because of maize seedling roots easily, fertilizer sucting ability is poor, fertilizer discharges slowly, causes the weak phenomenon of corn seedling growth growing way.Therefore, how to break through the traditional fertilization idea, seed manure and single fertilization are combined, promote the maize seedling roots growth by seed manure, the corn under-nutrition in seedling stage that additional single fertilization causes, reaching the effect of carrying seedling fast just becomes present technique field urgent problem.
Summary of the invention
One of purpose of the present invention is to provide a kind of corn seed manure specially that promotes the maize seedling roots growth, competent nutrient is provided for the corn seedling growth.
The objective of the invention is to reach by the following technical programs:
A kind of corn seed manure specially comprises nitrogen nutrient, phosphorus nutrient and potassium nutrition, it is characterized in that: the weight percent of described nitrogen nutrient, phosphorus nutrient and potassium nutrition is respectively 10%, 15%, 5%, also comprises the humic acids of 10%～20% weight percent in addition.
A kind of optimal technical scheme is characterized in that: the raw material of described nitrogen nutrient is ammonium nitrate, ammonium sulfate and monoammonium phosphate, and wherein three kinds of raw material weights ratios are 1:1:2～1:1.6:2.9.
A kind of optimal technical scheme is characterized in that: the raw material of described phosphorus nutrient is calcium superphosphate and monoammonium phosphate, and its part by weight is 0.34～2.9:1.
A kind of optimal technical scheme is characterized in that: the raw material of described potassium nutrition is vitriolate of tartar and Repone K, and its part by weight is 1～2:1.
Another object of the present invention provides the production technique of above-mentioned corn seed manure specially.
Another object of the present invention reaches by the following technical programs:
A kind of production technique of corn seed manure specially, its step is as follows:
(1) ammonium sulfate, monoammonium phosphate, general calcium, Repone K and vitriolate of tartar and humic acids are weighed in proportion, and sieve respectively, each base fertilizer of screening back proportionally requires to enter rotary drum granulator via metering outfit by hopper from hopper separately, mixes with the ammonium nitrate of molten state;
(2) meanwhile, suitable feeding saturation steam had both improved material temperature, made the material humidification again; Material is by the tablets press granulation;
(3) promptly enter the drying machine drying after step (2) gained pellet leaves tablets press;
(4) promptly obtain granular corn seed manure specially through screening, cooling.
Beneficial effect
The use of corn fertilizer of the present invention:
In corn seeding period, corn fertilizer of the present invention and corn seed together are manured into soil, for the corn seedling growth provides competent nutrient.
The present invention selects rational nitrogen, phosphorus, potassium nutrition ratio and raw material and filler to select, and promotes the maize seedling roots growth by seed manure, and the corn under-nutrition in seedling stage that additional single fertilization causes reaches the effect of carrying seedling fast.
Beneficial effect of the present invention:
(1) according to the nutrient demand proportioning nutrient of corn seedling growth to nitrogen/phosphorus/potassium, calculate the nutrient input amount by method of fertilization for target yield, finally determine 10/15/5 nutrients ratio.
(2) determine the nitrogenous fertilizer raw material by test, the nitrogenous fertilizer raw material mainly contains ammonium nitrate, ammonium sulfate and monoammonium phosphate and urea, because urea nitrogen fertilizer is easy to generate biuret, influence seed germination, thereby be 1:1:2～1:1.6:2.9 by testing definite ammonium nitrate, ammonium sulfate and monoammonium phosphate weight ratio.
(3) corn seedling stage is the critical period of phosphorus nutrition, and the abundance of phosphorus is supplied with most important to the growth of corn whole growing.Thereby, determine that water-soluble phosphorus and water-insoluble phosphorus ratio are the keys that guarantees corn available phosphorus in seedling stage, be monoammonium phosphate and general calcium by testing the raw material of having determined the phosphorus nutrient.
In fertilizer, add humic acids.Humic acids can form complex compound with metal ion iron, aluminium, calcium, manganese, copper etc., improves the validity of trace element in the soil, and humic acids can also activate by metal fixed phosphorus to promote the absorption of plant to phosphorus.In addition, the active group in the humic acids can with the ammonia effect, generate more stable ammonium salt, have good guarantor's nitrogen effect.
The present invention will be further described below by embodiment, but and do not mean that limiting the scope of the invention.
