【official website】what are the foreign articles on the fertilizer packaging bags that are fooling people-凯时娱乐ks

release time:2019-11-08

there are many kinds of chemical fertilizer, and the letters on the chemical fertilizer bag are also various. many farmers don't know much about the letters on the chemical fertilizer bag, and don't know what those letters mean
today, let's see what some letters on fertilizer bags mean.
letter summary of common fertilizer packaging bags
1. hnk
in the process of using fertilizer, we sometimes see some fertilizer bags marked with hnk on the market. after consulting the relevant information, there is no such sign of fertilizer.
in general, the compound fertilizer we meet is labeled with npk, n for nitrogen, p for phosphorus, and
p2o5 is k, k2o is k.
2. te
te indicates that the fertilizer contains trace elements.
manufacturers will generally describe the content and form of trace elements in fertilizers in their technical manuals. the main microelements are boron, iron, zinc, copper and molybdenum, among which chelated microelements are the best.
for example, balanced water-soluble fertilizer: 20-20-20 te. it means that the total nitrogen content of the water-soluble fertilizer is 20%, the content of phosphorus pentoxide is 20%, the content of potassium oxide is 20%, and te means that the fertilizer contains trace elements.
3. em
em is a complex bacteria group. we often see that the fertilizer bag is marked with em bacteria agent. it is mainly composed of several bacteria groups. all kinds of microorganisms play an important role, and the core role is dominated by photosynthetic bacteria and lactobacillus acidophilus. it consists of:
(1) photosynthetic flora. it can make use of the solar heat energy received by the soil or the ultraviolet energy to separate the hydrogen sulfide in the soil and the hydrogen in the hydrocarbon, and turn the harmful substances into harmless substances. it is the main force to enrich the soil and promote the growth of animals and plants.
(2) lactic acid bacteria. lactic acid bacteria (anaerobic type) produce lactic acid based on the absorption of carbohydrate and other substances produced by photosynthetic bacteria yeast. it can transform immature organic matter into effective nutrients for animals and plants, and effectively inhibit the proliferation of pathogenic bacteria produced by continuous cropping obstacles.
(3) yeast group. yeast (aerobic type) uses amino acids, sugars and other organic substances to produce active substances to promote cell division through fermentation.
(4) gram positive actinomycetes (aerobic). it takes amino acids and nitrogen from photosynthetic bacteria as substrate, and produces various antibiotics, vitamins and enzymes, which can directly inhibit pathogenic bacteria. it can enhance the resistance and immunity of animals and plants to various diseases.
(5) filamentous flora of the fermentation system (gas aversion). it can coexist with other microorganisms, especially for the formation of esters in soil.
4. hfk
through the relevant information, no relevant letter meaning was found. it may be the exclusive fertilizer of some manufacturers, or it may be the fertilizer used by some small manufacturers to play the edge ball.
if you encounter fertilizer packaging bags marked with such letters, you must be careful, and purchase fertilizer must go to the regular agricultural stores.
5. hak
the chinese name of hak is potassium humate. sometimes there are compound fertilizers containing hak in the market. generally, they are compound fertilizers containing potassium humate.
the humic acid functional group in potassium humate can absorb and store potassium ions, prevent the loss with water in sandy soil and eluvial soil, and prevent the fixation of potassium in cohesive soil.
in addition, some parts of potassium humate are low molecular humic acid such as fulvic acid, which has dissolution effect on minerals such as potassium silicate and potassium feldspar. it can slowly decompose and increase the release of potassium and the content of available potassium.
6. ha
ha is humic acid.
most of the humic acids on the market contain yellow humic acid, black humic acid and brown humic acid. among them, the yellow humic acid in it can regulate the growth of crops and control the expansion of stomata.
at the same time, potassium fulvic acid can be made by extracting certain yellow humic acid and potassium oxide from humic acid.
at present, scientific research shows that soil fertility depends on the content of humic acid in the soil to a great extent.
7. fa
fa is fulvic acid, which is a plant growth regulator, can promote plant growth, especially can control the opening degree of stomata, reduce transpiration, have an important role in fighting against drought, can improve the ability of plant resistance, increase production and improve quality, can be mixed with some non basic pesticides, and often have synergistic effect.
some fertilizer manufacturers will say that it contains fa factor functional fertilizer.
8. tm and r
tm is a trademark that is being accepted. as long as it is accepted, it will succeed. no one else can use it. r is accepted successfully. no one else can use it.
special attention:
when buying fertilizer on the market, the general mark of compound fertilizer is n, p2o5, k2o, so if you encounter some fertilizer that is not marked like this, you need to be very careful.
for example, there is a package marked as compound fertilizer, but the following total nutrients are marked as follows: n-p2o5-kom or n-p2o5-hak. there may be something else at the end, but it is not k2o.
in the market, there are some compound fertilizers with the word "kom" on the outer package, including the manufacturer or dealer who explain that it contains potassium fertilizer. in fact, professionals say that "kom" has no relationship with potassium fertilizer, and "kom" is only a soil conditioning substance, which has the function of phosphorus and potassium removal. when you meet such compound fertilizer, you should pay attention to it. don't be fooled!
