Description
Technical field
The present invention relates to a kind of fertilizer, it is particularly a kind of containing chelated microelements without the special N P and K of boron pineapple nursery
Fertilizer.
Background technology
Pineapple is one of famous tropical fruit (tree), and stem is short.Leaf is most, and the arrangement of lotus throne formula, sword-shaped, top is tapering, full edge or has
Often band maroon, the leaf being born at the top of inflorescence diminish, often taken on a red color for sharp mouth, outside of belly green, back side powder green, edge and top,
Belong to Angiospermae, Monocotyledonae, floury endosperm mesh, light is shone, and is had and is eaten raw, and strand juice, decoct soup etc. is higher to be eaten
The medical values such as value, relieving summer-heat quenches the thirst, the antidiarrheal that helps digestion, pot flowers, can eliminate the unusual smell as the high-quality feed of ruminant.
Pineapple is to plant based on husky flood more, crown bud or descendants' bud from robust growth, this be ahead of time result, realize high excellent cultivation
The key of training, Quality of Seedlings are had conclusive effect to pineapple growth, can carried significantly using nursery formula fertilizer in seedling medium
The rooting promoting of seedling that height has just been transplanted, bromelia are happiness acid soil plant, and it 5.5 ~ 6.5 be optimal that pH, which is, meeting shadow during higher than 7
Ring absorption of the pineapple to nutritional ingredient, contained soluble organic fraction is preferable with 0.8 ~ 1.5 in water, and basic soil is difficult to apply, and makes
Into the limitation and Quality Down of pineapple nursery.
Nursery fertilizer of the prior art depends on import, and cost is higher, and poorly water-soluble be present, cold, soft, hard water is difficult
With 100% dissolving, it is difficult to the problems such as plant protection product with non-strong acid and strong base, such as insecticide, bactericide are used cooperatively, cause
Utilization rate is not high, it is difficult to be applied to spray, soilless culture is applied and prepared in drip irrigation and spray irrigation, pouring, punching, cultivate cost and greatly improve.
In plant growth must member be known as 16 kinds, be divided into a large amount of, middle amount, micro, a great number of elements：Carbon, hydrogen, oxygen, nitrogen, phosphorus,
Potassium；Moderate-element：Calcium, magnesium, sulphur；Trace element：Iron, manganese, copper, zinc, molybdenum, boron, chlorine, trace element have important rush to plant
Enter effect, but due to boracic in azophoska, boron can cause pineapple blade leaf roll or come off, in the prior art containing trace element
Fertilizer is also generally in the form of strong acid salt, such as a kind of dedicated fertilizer for ornamental pineapple that patent CN1884225 is proposed, including zinc sulfate
0.048 ~ 0.096%, copper sulphate 0.007 ~ 0.013%, sodium molybdate 0.013 ~ 0.024% etc., ion stability is poor, and security is poor, holds
Easily react and hydrolyze with other functional groups, it is difficult to it is absorbed by crops, antagonism is serious between element, so that utilization rate substantially reduces, into
This is higher.
The fertilizer of chelated microelements turns into study hotspot, if so-called chelate refers to that organic matter has one simultaneously
Individual salt forming group, wherein have reactive hydrogen atom can the person of being replaced and one into network group complex reaction coordination when, with metal sun
Ionization, in addition to having salification, also acted on into network.A kind of Chelating state as patent CN103467159A is proposed is compound micro-
Secondary element fertilizer and preparation method thereof, but use EDTA chelates more, EDTA chelates are not only expensive, rich metallic element
Content is few, and pH could need to well discharge metallic element up to more than 7, therefore, it is difficult to ensure that no boron pineapple nursery is faster and better,
And burden control difficulty is diluted when applying, excess salt branch causes water suction difficulty, physiological dysfunction even burn seedlings phenomenon, it would be highly desirable to
Improve.
The content of the invention
The purpose of the present invention is the defects of being directed to prior art, there is provided a kind of to be educated containing chelated microelements without boron pineapple
The special azophoska of seedling, in faintly acid, ion stability is high, and security is good, and water-soluble ability is strong, can be with the plant of non-strong acid and strong base
Protective agent uses simultaneously, and trace element easily absorbs, and utilization rate substantially reduces cost, improves pineapple nursery rush up to more than 90%
Root effect, effectively avoid, alleviate situations such as soil hardening, salinization.
