Tiny
particle
The tiny particle urea is suitable for various kinds of soil
and various kinds of crops, include the nitrogen that the high nitrogen
raised one, But and topdresses and uses as the base manure.
Content of moisture, temperature, organic matter, sour alkali
degree of the the speed and soil of the urea ammoniation course
of tiny particle are relevant, Too soil type, apply fertilizer degree
of depth influence of factor. Because tiny particle urea of our
company add and clear up pharmaceutical slowly, all ammoniation
time take than ordinary urea long, The fertilizer efficiency is
longer than the ordinary urea too, so, should use in early 3-5 days
more than the ordinary urea when peasant households use. At the
time of making the tiny particle urea base manure to use, it is
the nonirrigated farmland that is used before ploughing turning
over , Plough when looking through burying into soil deeply urea,
with fat the result of use is better together peasant family have;
It is paddy field that can fat to construct and down together peasant
family urea have, then ploughed and turned up the soil in front
of cultivated land, Poured water 2-3 days later, there is water
such as the paddy field, after constructed the urea, Can't turn
on the water , prevent the fertilizer efficiency from reducing.
Topdress the tiny particle urea while using, had better be constructed
by row replacement or the cave , try not to spread fertilizer over
the fields. When unable row replacement or the cave is constructed,
the best before and after the light rain , spread fertilizer over
the fields when the soil is moist. Make quantity should not too
much when turning green fat, make and divide tiller construct the
foot when being fat ear of grain fat. There is sure function of
increasing production too while doing foliage top dressing. Tiny
particle urea should make leave apply fertilizer, its density is
generally 0.5-2%.
The tiny particle urea can mixes and uses with peasant families,
such as big soya-bean cake, night soil, compost, barnyard manure,etc.
fatly , But because of the biological function of the emblem, will
accelerate the ammoniation of urea, so mix while using, Must mix
and use at the same time at the same time , can't not need for a
long time after mixing, so as not to cause losses of fertilizer
efficiency. Can with chlorine ization potassium, carbon nitrogen,
pass calcium phosphate, calcium chloride,etc. weak hygroscopicity
chemical fertilizer mixes and uses too, But will use immediately
after mixing, can't preserve for a long time . Also can mixes and
uses with sulphuric acid ammonium, sulphuric acid potassium, plant
ash, lime, ground phosphate rock fat, calcium magnesium phosphate,etc.,
Because above-mentioned assortment of chemical fertilizer have no
hygroscopicity basically, can mix at will . The tiny particle urea
can't mixes and uses with the chemicals fertilizer with strong hygroscopicity,
such as nitric acid ammonium, sodium nitrate, carbonic acid hydrogen
ammonium,etc. . |
