Description
Technical field
The present invention relates to a kind of corn fertilizer with slow release effect, belong to Crop fertilizer technical field.
Background technology
Corn is cereal crops and forage crop important in the world, and whole world total output highest crops, its
Cultivated area and total output are only second to rice and wheat.World today there are about 1/3rd populations and be used as main food using corn
Grain, wherein corn accounts for 50% in Asian food composition, more persons are up to more than 90%, and Africa accounts for 25%, and Latin America accounts for 40%.
Containing abundant protein, fat, vitamin, trace element, cellulose and polysaccharide etc. in corn, there is exploitation high nutrition, height
The great potential of biological function food.
Corn is most with nitrogen throughout one's life to N P and K demand, next to that potassium, phosphorus.Nitrogen is most as corn growth demand
Nutrient, nitrogen supply is sufficient, can effectively facilitate plant metabolism, enhancing photosynthesis, improve fringe weight and yield；Phosphorus
Element corn growth demand is not very big, but the available phosphorus content in soil is typically relatively low, so having to pay attention to phosphorus
The application of fertilizer, phosphate fertilizer abundance are favorably improved corn color and luster and quality, promote precocious；Potassium all needs in the whole period of corn growth
Supplement, potassium abundance can effectively facilitate the content of starch, sucrose, cellulose in plant body, promote stalk mechanical tissue and Hou Jiao
The hair degree of tissue, improve disease-fighting capabilities.
In corn growth seedling stage, because vegetation growth is slow, the uptake of npk fertilizer is limited, and speed is also relatively slow,
Uptake only accounts for less than the 10% of gross absorption.But now the demand concentration of three kinds of elements is highest in life in plant
, it can be seen that, seedling stage sufficient fertilizer plays the role of positive for nurturing staff.Absorption of the jointing to tasseling stage to nutrient
Quantity is most, fastest, is the critical period for needing fertilizer.The absorption of modern breeding time has been accounted for the nitrogen and phosphorus that when taking out hero, plant absorbs
50% or so of amount, the uptake of potassium is up to more than 70%.The effect now applied fertilizer is maximum, is the maximal efficiency phase of fertilizer, because
And it is also the critical period of corn fertilizing.After pollination, the nutrient of absorption increases corn, but infiltration rate slows down substantially.To breast
Ripe phase, the potassium that corn needs all absorb, and also oneself absorbs more than 90% for nitrogen, phosphorus.From milk stage to maturation, corn is to nitrogen, phosphorus
Still there is certain absorption, it is still necessary to the lasting supply of fertilizer.At present, the fertilization mode of corn is complicated, it is necessary to apply fertilizer three times, increases
Labour cost.In addition, China's corn planting scope is wide, climate and soil conditions difference is big, causes corn fertilizing to exist not
Few problem, especially azophoska, which are matched somebody with somebody, applies phenomena such as unreasonable generally existing.
The content of the invention
It is an object of the invention to solve the deficiencies in the prior art, there is provided a kind of corn fertilizer with slow release effect,
Make npk nutrient equilibrium, utilization rate of fertilizer high, be not only able to strengthen soil fertility, extend fertilizer efficiency, and top dressing can be reduced
Number, labor intensity, saving of work and time are reduced, and the yield and quality of corn can be improved.
Technical scheme
A kind of corn fertilizer with slow release effect, is made up of the raw material of following parts by weight：40~42 parts of oxamides, 12
~14 parts of urea, 23~26 parts of phosphate fertilizer, 17~18 parts of potash fertilizer, 1~3 part of zinc fertilizer, 4~7 parts of bentonites.
Further, the phosphate fertilizer is the mixture of MAP, Diammonium phosphate (DAP) or the two arbitrary proportion.
Further, the potash fertilizer is potassium chloride.
Further, the zinc fertilizer is zinc sulfate.
Principle active component be N P and K in the corn fertilizer of the present invention, the nitrogenous fertilizer of the special fertilizer be slow-release nitrogen fertilizer with it is general
Logical azophoska is mixed by proportioning, and the corn fertilizer total nutrient content is 44%~47%, wherein nitrogen N effective content
For 23%~24%, phosphorus P2O5Effective content for 11%~12%, potassium K2O effective content is 10%~11%, its mesoxalyl
The pure nitrogen level of amine accounts for the 53%~58% of nitrogen pool.
The preparation method of the above-mentioned corn fertilizer with slow release effect：By oxamides, urea, phosphate fertilizer, potash fertilizer, zinc fertilizer and
Bentonite crushes, and is uniformly mixed, then by being granulated, is then dried at a temperature of 60-80 DEG C, produce corn fertilizer.
In use, the corn fertilizer of the present invention is applied as base manure, every mu of amount of application is 40~50kg.
The advantage of the invention is that：(1) apply simply, applied as base manure, top dressing number, saving of work and time can be reduced；(2)
Fertilizer nutrient is balanced, and fertilizer amount and corn demand are basically identical, it is ensured that the nutrient supply in corn growth prometaphase；(3) specially
There is good sustained release performance with the oxamides in fertilizer, both may insure demand of the Maize in Earlier Stage to nitrogen, and can ensures corn
The lasting supply of middle and later periods nitrogen., can using the corn fertilizer of the present invention when nutrient dosage is identical compared with habits fertilization
Make corn yield increasing more than 5%, obvious effect of increasing production.
