How to identify the true and false of imported water soluble fertilizer
1, smell, then don't say it, everyone knows;
2, the appearance, must be dyed (red, blue, green), because the foreign fertilizer is designed for the big farm, if it is colorless, add to the farmer does not know, it may be added once more resulting in excessive concentration;
3, there are black spots, green spots, etc., those are trace elements, and the distribution is relatively uniform (this is generally not possible in China), mainly equipment problems (horizontal and barrel-like mixing opportunities have about 10%) The dead angle leads to uneven mixing. Foreign countries are double-spiral cone mixers and require 30 minutes of mixing);
4, less water, an open secret, in order to reduce costs, the domestic use of powdered urea (some directly with the particles to crush), this is the moisture absorption, the lowest, when the urea reaches 30%, use Hand pinch can be found to be very sticky, it will be dyed on the hand when it is photographed, and the imported one will not be dyed on the hand;
5, the use of results, has been used, will find that good imported water soluble fertilizer will be harvested for a period of time, as long as people's living conditions will be longevity. And the water-soluble fertilizer with hormones will have premature aging, and the disease will be more, just like people who eat drugs.
6, the price has changed, in fact, many times, the price is indeed very high, but like imported pesticides, most of them are spent on research and development. Water-soluble fertilizer is spent on experiments. For example, I was exposed to an imported water-soluble fertilizer. At a test base around Wuhan, they rented 30 mu of land and spent a year proving that the product is suitable for the crops in the region. In the first two years, the sale will be more expensive. At the beginning of the third year, the price will not be expensive. Because the cost is recovered, they think that the product is already an old product, and it should not be too expensive.
Therefore, the imported products are expensive and should not be expensive after three years. As far as I am concerned, at the beginning, it was 15 pounds of retail, and later 12 pounds, to release new varieties, and some areas even promoted sales as low as 10 yuan a pound.
7, the product has characteristics, either phosphorus-calcium combined (Kangli, He Likang), or has a certain sustained release effect (En-state grams of fertilization), or added a promotional component (American Yo Ma red Powerful fertilization, promote absorption) and so on, while domestic speculation is high (high have a fart, can not absorb), hormones are good (drugs are good drugs, what kind of lipid is more expensive than sulphonate sodium, the effect Hidden points), improved soil, etc. (more esoteric, can also release the soil's fixed substances, do you dare to make some precipitation to make the ionic state? He Likang dare phosphorus calcium combined, take the phosphorus calcium precipitate to break it down to you Look)
Imported water soluble fertilizer and domestic water soluble fertilizer have the same point:
1. Imported water-soluble fertilizer and domestic water-soluble fertilizer are basically the same in nutrients and content. They are all quick-acting, water-soluble fertilizers, which improve the disease resistance, cold resistance, drought resistance and lodging resistance of crops, and extend the shelf life and storage period of crops.
2. After use, the fruit is evenly colored and well-sized, which can promote early maturity and early listing.
3, the use of the method is to directly spray on the page, flushing, drip irrigation and so on.
The difference between imported water soluble fertilizer and domestic water soluble fertilizer:
1, the price is different, the import is more expensive than the domestic, because the import of water soluble fertilizer needs to increase the income of other aspects, such as tariffs, so the price of sales is expensive. Domestically produced water-soluble fertilizers have no tariffs and various costs incurred in the intermediate stages of the compound, so it is cheaper than the same amount of imported water-soluble fertilizers.
2. In the market, when China's water-soluble fertilizer has not developed, the imported water-soluble fertilizer does occupy the high-end market of water-soluble fertilizer in China. However, with the continuous development of China's water-soluble fertilizer technology, it has achieved quite good results in recent years. Breakthrough, gradually importing water soluble fertilizer will also be gradually driven out of the market in China. (source network)

These test kits are performed on blood samples from infected persons became a useful tool in elucidating the links between several cases. These links would not have been made if viral particles were looked for via PCR methods. This is due to the fact that the patient's immune defence might be successful in eliminating the virus and hence removing any trace of where it came from. However, when specific antibodies are searched for in the same patient, they will be able to be detected because they stay within the blood for several years. Commercial immunoassay tests to detect COVID-19 include a dual ELISA test to be performed. This detects specific IgA and IgG against the virus in the blood of infected patients. There is also an automated fluorescent immunoassay system to measure quantitatively or semi-quantitatively the concentration of the targeted analyte, which can be the viral antigen or IgM/IgG.
