Abstract
The invention relates to a special fertilizer for corn, which in detail is a mixed one-time deep dressing special fertilizer for corn. It comprises following steps: (1) preparing long effective agent, mixing humic acid 5-10 kg, dicyandiamide 5-10 kg, cyanide chinone 2-6 kg; (2) mixing long effective agent 1-2 kg, ammonium diacid phosphate 25-30kg, potassium chloride 20-25kg, single superphosphate 25-30kg, multiple microelement 3-5kg, bentonite 4-5 kg, preparing compound fertilizer; (3) adding large potassium chloride 75-80kg,diammonium phosphate 95-100kg, urea with large particle 240-250kg into said compound fertilizer, stirring evenly and getting deep-dressing special fertilizer for corn. The invention is characterized by good effect, increased fertilizer utilization rate, longer fertilizer efficiency, ability to increase quantity and benefit.
Description
Technical field
The present invention relates to corn fertilizer, a kind of specifically mix type maize subsoil-application special-purpose fertilizer and production method thereof.
Background technology
Corn is one of farm crop important in China's agricultural, mainly is distributed in ground such as northeast, northwest and North China, because geographic difference, its planting patterns also is not quite similar.Traditional maize culture growing period generally all through two shovels, twice, one topdress and other control measures, this cultivating method operation is heavy, labour intensity is big, does not adapt to the paces that agricultural modernization develops.In fertilizer industry, corn fertilizer is one of more general special-purpose fertilizer, it is made up of nitrogen, phosphorus, potassium and trace element, this special-purpose fertilizer also will carry out above-mentioned operation after applying soil, its utilization ratio is not high yet, not only time-consuming but also require great effort, so this special-purpose fertilizer can not alleviate peasant's work burden and economical load.People had added synergistic agent again in corn fertilizer afterwards, were carrying out compound granulation.But this method very easily makes the nutrient content in the fertilizer run off, and has caused very big waste again.
Summary of the invention
In order to overcome above shortcoming, the objective of the invention is to propose a kind ofly can satisfy the budding fertilizer requirement of corn whole growth, do not make the corn fertilizer new class maize subsoil-application special-purpose fertilizer that nutrient content runs off in process of manufacture again.
For achieving the above object, when the present invention produces at corn fertilizer, add sustained release drug when earlier phosphorus, potassium and trace element being carried out granulation, allocate required nitrogen, phosphorus, potash fertilizer afterwards more in addition into, the loss of nitrogen in the time of so not only can effectively avoiding producing, behind the incorporation of fertilizerin the soil, sustained release drug will be to its generation effect before decomposition for nitrogenous fertilizer, and then reaches long lasting purpose.
Concrete technical scheme is:
Maize subsoil-application special-purpose fertilizer, it can prepare as follows,
1) making of sustained release drug: 5-10 kilogram humic acid, 5-10 kilogram Dyhard RU 100,2-6 kilogram cyanogen quinone, puddle evenly after promptly;
2) 1-2 kilograms of sustained release drugs, 25-30 kilograms of monoammonium phosphates, 20-25 kilograms in Repone K, 25-30 kilograms of calcium superphosphate, 3-5 kilograms of multielement micro-fertilizers, wilkinite stir for 4-5 kilograms, carry out compound fertilizer pelletizing;
3) 2) in compound fertilizer pelletizing after add big 75-80 kilograms in Repone K of grain, 95-100 kilograms of diammonium phosphate, big 240-250 kilograms in urea of grain and stir, promptly get maize subsoil-application special-purpose fertilizer.
The content of maize subsoil-application special-purpose fertilizer: account for about 50% of fertilizer gross weight after amounting to into total nitrogen, Vanadium Pentoxide in FLAKES, Repone K, the ratio of nitrogen, Vanadium Pentoxide in FLAKES, Repone K is 1-0.9585:0.4174-0.4711:0.4085-0.4674.
The present invention has following advantage:
1. application effect is good.Because fertilizer is disposable to apply, the farming number of times that has reduced soil has also reduced moisture evaporation, improves 2-3 percentage points of soil moisture contents.Especially autumn dispensing, through snowfall retaining in winter, suppression, windyly causes the loss of moisture at arid when having avoided applying because of spring, saves seedling from damage for spring sowing and lays a good foundation.
2. improved fertilizer utilization ratio, fertilizer efficiency is long, increases output, has improved benefit.Because after sustained release drug is manured into soil, long-time slowly decomposition discharges nutrient, and supplying with crop needs, avoid the nutrient waste that the traditional fertilization method misses the farming season because of the no rain of weather arid can't topdress or concentrated fertilizing nutrient enrichment causes, improved utilization rate of fertilizer 10-15%.General grain number per spike increases more than 20, and 100-grain weight increases, and stimulation ratio reaches 10-20%.Improved overall economic benefit.
3. good in economic efficiency, labour intensity is low.After the fertile disposable bottom application of special use of the present invention, crop does not need to topdress, and can simplify production management, and saving of labor, laborsaving has reduced labour intensity.
