The application of high-efficiency multi-function fertilizer rich in selenium of the present invention, soil deeptillage is disposable after spring break applies, and need not the whole year to apply fertilizer once more.
The technical characterstic of high-efficiency multi-function fertilizer rich in selenium of the present invention is; Utilize the coat fertilizer Nutrient Release of different coated fertilizers such as chitosan, sulphur, according to the law of nutritive absorption of crop, carry out the different single controlled release fertilizer of planting that discharge the period of specific coating quantity composite simultaneously; Be equipped with diammonium phosphate, vitriolate of tartar again; In addition, also be equipped with Sodium Selenite, zinc sulfate, borax the needed trace elements of farm crop such as selenium, zinc, boron are provided, accurately control nitrogen, phosphorus, potassium to discharge according to the requirement of crop growth law of nutritive absorption at different times; Through field experiment, this fertilizer has raising the output, increases income and improves the beneficial effect of quality.
Excellent results of the present invention is following:
1, nutrient reasonable ratio improves utilization rate of fertilizer, has realized the identical basically of fertilizer nutrient release profiles and crop growth phase nutrient demand curve
Because the chitosan surface has vesicular structure; Be beneficial to the infiltration diffusion of moisture and nutrient, also possess biodegradability simultaneously, the present invention adopts chitosan that composite fertilizer is carried out coating and handles; Utilize the infiltration and the degradation speed of chitosan film to control release to nitrogen phosphorus potassium; Adopt sulphur that urea is carried out the release of coating processing controls nitrogen, its nutrient is along with the absorbing rule of farm crop progressively discharges, and the nutrient that retains in the soil is less; Therefore the loss of fertilizer and fixing minimizing, so utilization rate of fertilizer is high.
2, improve farm crop resistance, obvious effect of increasing production
Adopt chitosan as coated fertilizer, not only have biodegradability, environment-protecting asepsis; And chitosan can also suppress the growth of phytopathogen, and actively inducing plant produces resistance of wide spectrum, therefore; Product of the present invention can improve farm crop resistance, reduces the farm crop sickness rate, makes farm crop tree bulk-growth sane; Blade increases, and the leaf look dark green, obvious effect of increasing production.
3, single fertilization need not to topdress the whole year, saves labor
In order to realize the high-yield culturing of farm crop, generally need carry out 5 fertilisings in 1 year, the effort of taking a lot of work; And adopting high-efficiency multi-function fertilizer rich in selenium of the present invention, single fertilization need not to topdress the whole year; Reduce peasant's labour intensity, practiced thrift the recruitment cost, improved economic benefit.
4, owing to added trace elements such as selenium, zinc, boron, significantly improve crops quality
Research shows, selenium has anti-cancer and cancer-preventing, enhances human body immunologic function, hypoglycemic, protection cardiovascular and cerebrovascular, prevention cataract and effect such as delay senility, and therefore is referred to as " anticancer king " in the body trace element by scientist.Specially added the selenium element in the formula for a product of the present invention; Can become organoselenium albumen to be stored in bud and leaf, the stem of crop the bio-transformation efficiently of selenium element; Can not only guarantee agricultural-food and food safety effectively; But also have many effects such as the inherence of improving farm crop and exterior quality, thereby reach purpose through farm crop being improved selenium content simultaneously to the health increase selenium element of human body.
In addition, zinc and boron also are the indispensable nutritive elements of crop growth, and scarce zinc can suppress plant-growth; Chlorosis between vein; And it is sick to cause various plants, and boron deficiency can make the plant fruit drop serious, has also added zinc element and boron in the formula for a product of the present invention.
