Abstract
The present invention discloses a particle fertilizer for corn. Ingredients composed of 35 to 38% of ammonium sulfate, 3 to 5% of urea, 6 to 8% of diammonium phosphate, 36 to 39% of ordinary superphosphate, 14% of potash fertilizer, 1% of trace element and 2 to 5% of decomposed bioorganic fertilizer are pulverized after being uniformly mixed according to weight ratio, and granulated by a granulator after proper quantity of water is added, and the granulated ingredients are cooled and packaged so as to obtain the fertilizer; the present invention has the advantages of high emergence rate in holes (more than 97%), no harm to seeds, remarkable effect of strengthening and building seedlings, economy and high efficiency, saves plowing expenses of plowing and sowing, and simultaneously enables the yield of corn to reach 590 kg/mu and the yield to increase by 11.2%.
Description
Technical field
The present invention relates to a kind of seed manure of corn.
Background technology
China is the area of having a large population and a few land, as wheat stubble maize plantings such as Jiangsu, Shandong, Henan, Hebei, be in the last ten-days period in May to June, the last ten-days period.Often be in arid and waterlogging caused by excessive rain during this period and replace season, plough sowing and meet the lost easily moisture content of dry year, influence is emerged, and rainfall is too much, and the draining difficulty is prone to stiff seedling.The eighties along with the popularization of hybrid maize, has been taked the live way of plate stubble since mid-term, prevents above-mentioned situation.From the angle of preserving the ecological environment, reduce hazards of sand storms also is useful; but cause the fertilising difficulty; corn desired nutritional in seedling stage nitrogen, phosphorus, potassium, trace element and fertilizer can not get replenishing; the seedling bulk-growth is slow; and the sunlight aboundresources of this moment; nourishing body is too small, influences the further raising that photosynthesis consequently influences output.As the simple substance fertilizer of spreading manuer in holes common, compound fertilizer, easily cause and burn the disconnected row of planting, be short of seedling, influence mature spike number.Fill the gaps with seedlings as transplanting, it is uneven to cause seedlings, seedling to grow, and influences the ripening stage, causes the underproduction.Seed and fertilizer are from far away excessively, and supply and demand in time also made the maize seedling delayed growth to nutrition after seminal root took place.
Summary of the invention
The purpose of this invention is to provide a kind of can with corn with the bunch planting kind, do not influence efficient, the strong seedling of emergence of corn, the particle fertilizer for corn of volume increase again.
The object of the present invention is achieved like this: by weight with ammonium sulfate 35～38%; urea 3～5%; diammonium phosphate 6～8%; normal superphosphate 36～39%, potash fertilizer 14%, trace element 1%; biological organic fertilizer 2～5% becomes thoroughly decomposed; pulverize after being mixed evenly, add the tablets press granulation of an amount of water, it is fertile that cooling packing becomes.
Described trace element is zinc sulfate, ferrous sulfate, manganous sulfate, borax;
The described biological organic fertilizer that becomes thoroughly decomposed is chicken manure or dregs of beans.
The effect of ammonium sulfate is to utilize the ammonium sulfate stable in properties, does not burn kind of (not influencing seed germination emerges), can increase granulation intensity; The effect of urea is to improve nitrogen content, meets hot lubricate, smooth surface during granulation; The effect of normal superphosphate is to increase phosphorus nutrition, plays the bonding granulation; The effect of potash fertilizer is to supply with potassium nutrition; Effect of trace elements is to replenish crop trace element; The biological organic fertilizer that becomes thoroughly decomposed not only provides nutrition but also play weighting material.
Advantage of the present invention: 1. cave seedling rate height, 5～7 kilograms of every mu of amounts of application, whenever spread manuer in holes with 2～3 and corn with the bunch planting kind, do not burn kind, the cave seedling rate reaches more than 97%, and every mu used 5 kilograms and only have 70～75% with the seedling rate of spreading manuer in holes with urea, and the seedling rate of the same common 25% compound fertilizer of spreading manuer in holes only has 76～82%; Strong sprout, strong seedling effect remarkable, according to test, corn five leaves are wholeheartedly investigated, and whenever spread manuer in holes with 3, plant height 55cm does not more execute the increase 11cm of seed manure, the thick 2cm of stem increases 0.3cm, dry matter 26 gram/strains, increase by 6 gram/strains; 3. economical and efficient has been saved the tractor-ploughing expense of ploughing sowing, and corn per mu yield simultaneously can reach 590 kilograms, volume increase 11.2%.
Embodiment
Get 38%, 38 kilogram in the ammonium sulfate that contains N21%, free acid＜0.08% by weight; 3%, 3 kilogram in the urea that contains N46%, biuret≤1%; 6%, 6 kilogram of diammonium phosphate; Contain P
2O
5〉=14%, the normal superphosphate of free acid≤5.5% is 36%, 36 kilogram; 14%, 14 kilogram in Repone K; Reach GB with apply fertilizer.1%, 1 kilogram of trace element, wherein zinc sulfate is 0.6 kilogram, 0.2 kilogram in ferrous sulfate, 0.1 kilogram of manganous sulfate, 0.1 kilogram of borax; 2%, 2 kilogram of chicken manure that becomes thoroughly decomposed or dregs of beans amount to 100 kilograms; above-mentioned fertilizer is mixed evenly pulverizes, add 5% water, with Qingpu, Shanghai FYC type Squeezinggranulator extruder grain; utilize the mill of 5mm; granulation is success once, and granulation is shaped as cylindric, length 1.6～2cm; cooling packing; with the bunch planting kind, do not burn kind, play strong seedling effect.
