Description
Technical field
The present invention relates to fertilizer field, in particular to one kind is exclusively used in fertilizer special for celery cabbages and preparation method thereof.
Background technique
Generally existing chemical fertilizer input amount is excessive in the production of China vegetables, the low problem of utilization rate of fertilizer.As utilization rate of nitrogen fertilizer is
30%-35%, phosphate fertilizer utilization efficiency 10%-20%, potassium utilization rate 35%-50%.Since nitrogenous fertilizer acts on vegetable increase production
Significantly, nitrogen fertilizer amount is excessively especially prominent, and a large amount of unemployed nitrogenous fertilizer enter water body by eluviation and water body richness is caused to be sought
Feedingization, or volatilization lead to air pollution, or deposition is in the soil, cause Soil Nitrate, nitrite enrichment, cause soil sour
A series of ecological problems such as change, salinization, underground water pollution.Excessive fertilization not only reduces the economic benefits at vegetable cultivation family,
Environmental pollution is brought, and the food high containing nitrate, nitrite is eaten for a long time, it is strong to will affect human body by food chain
Health, serious person cause canceration.
Chinese cabbage (Brassica rapa L.ssp.Pekinensis (Lour.) Hanelt) is Cruciferae Brassica genus
(Brasscia) one of most important vegetable crop, originates in China in, is one of maximum vegetable crop of China's cultivated area,
Distribution area is wide, and yield is high, storage tolerance, and the supply phase is long, full of nutrition, eating method multiplicity, the vegetables production and daily in China
Space of top prominence is accounted in consumption.National cultivated area has reached 2557.9 thousand hectares within 2012, and shelter has vegetables first.Chinese cabbage removes
Except eating as vegetables for people, also have effects that clearing heat and relieving fidgetness, diuresis of quenching one's thirst, tonneau stomach, often eating Chinese cabbage can
Prevent vitamin C deficiency (scurvy).
The fertilizer of Chinese cabbage application currently on the market is mainly conventional fertilizers kind, such as simple substance urea, calcium superphosphate, chlorination
Potassium and N P and K ternary compound fertilizer etc. are generally free of middle and trace element, and not only fertilizer specific aim is poor, fails sufficiently to send out
The yield increasing effect of fertilizer is waved, moreover, Chinese cabbage breeding time or harvest time are longer, needs multiple top dressing, it is time-consuming, also increase life
Produce cost.
Summary of the invention
The present invention provides a kind of dedicated fertilizers for improving Chinese cabbage nutritional quality and flavor.
The purpose of the present invention is what is realized by following measures:
A kind of fertilizer special for celery cabbages, it is characterised in that: using sulphur as coated fertilizer, sulfur coating layer quality is gross mass
10%-25%；It include 0.10 part -0.15 part of N-(n-butyl) thiophosphoric triamide (nBPT), dicyandiamide (DCD) 0.10 in coating
- 0.40 part of part, in terms of mass fraction.
It further, further include 10 parts -17 parts of urea, 9 parts -13 parts of monoammonium phosphate, 6 part -9 of potassium dihydrogen phosphate in fertilizer
Part, 18 parts -20 parts of potassium chloride, 2 parts -4 parts of magnesium sulfate, 0.3-0.6 parts of ammonium molybdate, 3 parts -4 parts of borax, 1.1 part -1.5 of zinc sulfate
Part, 2.1-2.3 parts of calcium chloride, 3 parts -5 parts of peanut meal, 5 parts -8 parts of wormcast, 4-9 parts of turf, in terms of mass fraction.
Fertilizer core main component provided by the invention is N, P, K, sulphur and it is a small amount of in microelement and urase, nitrification inhibit
Agent, nitrogen nutrient form include ammonium nitrogen, nitrate nitrogen, amidonitrogen, are for dedicated made of the research and development of Chinese cabbage uptake characters
Coating type fertilizer promotes absorption and combination to nitrogen, thionin using the coated fertilizer of sulfur-bearing, improves cystine in Chinese cabbage body
And methionine, volatile matter content, improve the nutritional quality and flavor of Chinese cabbage.
Chinese cabbage is the sensitive crop of sulphur, needs sulfur content height；Sulphur is the main component of vegetable egg white matter, in Chinese cabbage amino acid
In, there are about 90% sulphur contained in amino acid, and the amino acid of sulfur-bearing has methionine and cystine etc..The present invention improves methionine
With the content of cystine, the nutritional quality of Chinese cabbage is improved.Meanwhile glucosinolate and its catabolite are the masters of Chinese cabbage
Active constituent is wanted, delicate flavour is as caused by glucosinolate catabolite isothiocyanates.In addition, in volatile materials
Compound such as sulfuric acid Aden basic ring pentyl ester, 4- methylthio butanenitrile, phenethyl isosulfocyanate and isothiocyanic acid ring pentyl ester etc. is also
Sulfur-containing compound, they decide the flavor and nutritional quality of Chinese cabbage.
Preferably, above-mentioned fertilizer special for celery cabbages, nBPT purity >=97.0%, DCD purity >=99.5%.
