Chemical fertilizer is having main effect in agricultural production
Can promote soil fertility not only
Still can raise crop yield
Because this always has a few " flicker is round " can go up in chemical fertilizer make an issue of
Fraud of the type that use a flower comes the hard cash of diddle farmer friend
These National People's Congress can choose information more the village of inconvenience of out-of-the-way, traffic; Hitting what invite from Beijing " agricultural expert " cover, the organization cultivates a spot " give lessons " , explain the administrative technique of crop increase production, return can special specification to say a technology only, do not sell goods; Final flicker group still provides the after service that free deliver goods comes.
A flow comes down, always have a lot of villagers by brainwashing, darling from dig down, think oneself collected defecate appropriate.
Can group of the flicker that be what always succeed?
Above all, these gangs held the mentality of petty gain of most person covet.
Compared with agricultural expert, farmer people relatively dilettante to the professional knowledge understanding of chemical fertilizer, hear these low chemical fertilizer and normal fertilizer content identical cheap still a few hard to avoid will be enchanted, wait plus a few given little gift, free service, farmer people natural meeting classics does not live temptation is deceived.
Next, these " flicker is round " legerdemain is excellent, with a pair of shiver tongue, can 3 say loftily without fertilizer.
Flicker is round people can of do sth on a large scale in village activity, place probably of jab of somebody dark jab give them support, both sides cooperates, cent takes deduct a percentage from a sum of money, a lot of people also can fall into enemy hands before the interest.
Because of this farmer friends must sharpen one's eyes, keep sober, must not by all sorts of fair-spoken cover a region.
The following view is suspect!
"26 bacterium, 28 bacterium " , the sort of bacterium exceeds bid more
There is the biology fertilizer that contains 5 kinds to reach sort of above beneficial bacterium rarely on the market actually, expert of Ministry of Agriculture suggests: Biology fertilizer adds microbial sort to should not be more than 3 kinds.
The amount of bacterium exceeds bid taller
The amount of bacterium is exorbitant bring two issues: It is cost raises; 2 it is exorbitant microbial content may bring undesirable consequence to crop, restrain for instance grow.
One character shoulds not " foreign entrance "
This is current the commonnest conduct propaganda catchword, actually the fertilizer of dissolve of alleged entrance water of 90% above is homebred goods, still have some closer year of occurrence a few concepts are compound fertilizer also is this legerdemain.
All sorts of " potash fertilizer " enter the world
Potassium is more expensive, so some fertilizer remove a name to cry directly " × × Potassium " , but makings of this seed manure often is being hit " yellow corrupt acerbity Potassium " , " tall Potassium " banner, inside the content very little of potassium.
"Fertilize, need not top application "
Everybody has the mentality that saves labour, save labour, save money, but the cushy job that in the world does not have get sth done once and for ever, if chemical fertilizer of what kind of tagged such effect, pull immediately certainly black.
Get behind chemical fertilizer fraud, we can differentiate true and false even, ability picks such farmer friends in the agronomic activity henceforth truly useful chemical fertilizer will help him increase production add close, so how to keep away from " Xi Bei goods " , small make up this to be raised action.
Look: See fertilizer pack. The fertilizer that normal manufacturer produces, heal of the standard of its outer packing, strong, bag that pack is close. Note commonly the manufacturing licence, executive standard, licence that register, brand waits; Fake of fertilizer pack general coarser, the message on the bag that pack is not clear.
The 2 size that see fertilizer. Nitrogenous fertilizer (outside lime nitrogen) it is crystallization body more with potash fertilizer; Phosphate fertilizer is lump more or be not crystallization body pulverously, if calcium magnesium phosphate is pulverous shape, general calcium is poriferous, lump more; High grade and compound fat granuality and proportion are evener, smooth, unfavorable moisture absorption mixes the surface agglomerate. And inferior fertilizer rather, fertilizer grain size not all, coarse, humidity agglomerates greatly, easily.
Feel: Put fertilizer in control, handhold forcibly or press press roll, have " oily humid feeling " it is quality goods namely; And dry be like first probable pretend to be.
Smell: The special scent that carries fertilizer will be judged simply. If bicarbonate ammonium has intense ammoniac stink; Ammonium sulphate somewhat acidity; General calcium has tart flavor; And fake fertilizer criterion odour is not apparent.
Wet: If outside observation distinguishs chemical fertilizer breed not easily, also can try to distinguish according to deliquescent in water state. Spread fertilizer grain at damp ground or use a few water wet, after spending period of time, can undertake judging according to the deliquescent circumstance of fertilizer. For instance saltpetre ammonium, potassium sulfate, potassium chloride can dissolve completely (change) , the part such as general calcium, double superphosphate is deliquescent; Compound fat grain is met disperse the internal heat with sudorifics, deliquescent or have a few hangover, and very poor or sex of fuse of false bad fertilizer is far from deliquescent (divide phosphate fertilizer) .
Finally, remind everybody again, buy farming endowment should arrive normal, familiar farming endowment inn goes buying, not want to yield the crop of one season, was gotten to reduce crop by person flicker.
