Friends who know something about agriculture should know that the peasant uncles are most worried about all kinds of insect infestations and agricultural diseases, because these will lead to a significant reduction in the yield of crops, but you know? There is a plant disease that, far from being repulsive, makes the peasant uncles smile, because after the lesion, the economic benefits of the derived products are higher than those of crops, and their value is comparable to gold.
This lesion comes from corn, and the product after the lesion has many names, you can call it "Umi", "Black Truffle", or its original name "Corn Black Powdery Mildew". This kind of thing does not look good, and can even be said to be extremely ugly, at a glance, you will only think that there are tumors on the corn, but if you did farm work when you were a child, you will know that these "cancers" are good treasures!
When we were young, the main value of the corn black powdery mildew was only reflected in food and medicinal use. Because it has a sweet taste in itself, everyone often eats it raw, of course, some people will choose to fry it, and it will have a different flavor. In addition to being delicious, the medicinal value of corn black powdery mildew is also very high, not only can treat blood deficiency, fever and yin and yin injuries, tiredness and thirst and insufficient fluid, but also can prevent and treat a series of liver and gastrointestinal diseases, it can be said that its live and detachment is a kind of "fairy grass".
It is precisely because it is extremely valuable, so with the development of the times, corn black powder mushrooms have not been eliminated by people, but have become more and more sought after by people. You can often see people running to the countryside to buy corn black powder mushrooms, and even give a high price of every twenty or sixty yuan, which undoubtedly proves that this fungus has extremely high economic benefits, and this is the case. If you go to the cornfield every year during the corn harvest season, there is no problem in making tens of thousands of dollars a year. The only problem is that it is too hard, and each acre of land can only be found about two or two, and the benefit is really not high.
So why is it that this kind of thing was common when we were young, but now it is becoming less and less so rare that it has achieved a price increase when things are scarce and expensive? The reason is very simple, that is, with the continuous progress of scientific breeding, corn is more and more resistant to disease, which is why most of the corn black powdery mildew grows in the old corn field, because the field where the new type of corn is grown, there is often no living space for this fungus.
So which environment is most suitable for the growth of corn powdery mildew? What kind of form does it have?
In general, maize powdery mildew parasitizes the surface, soil, disease residues and soil manure, especially in some places with low temperatures, drought and little rainfall, the survival rate of this fungal spore is the highest and the longest survival time. As for the germination of powdery mildew spores, it is even simpler, only the dew at night is enough to make it soaked in it during the growth of corn, thus producing a complete corn powdery mildew.
Many people think that powdery mildew will only be impregnated when corn is in the seed period, but this view is wrong. Although powdery mildew is indeed a localized impregnation disease, during the entire development period of corn, powdery mildew can be impregnated, which is also a major reason why powdery mildew mushrooms used to occur more often.
As for the form of corn powdery mildew, we also mentioned it earlier, that is, it is a tumor-like tumor. Of course, growing from a spore to such a huge spore heap also requires a process. At the beginning, the spore size of powdery mildew is at the micron level, and when they are intertwined to form spore clusters, the largest is about 25 microns, until the development of the spore heap period, that is, the maturity stage, the corn powdery mildew bacteria will develop into a tumor with a diameter of 3-15 cm. Of course, there are also cases of longer ones, and the spore piles of corn black powder bacteria that grow in different growth environments will also be different.
As we mentioned earlier, the economic benefits of this corn black powder mushroom are extremely high, so can it be planted on a large scale? At present, it is not possible, and our technology is not up to this level, but in Germany, the technology is more advanced, and they already have a factory specializing in the production of corn black powder mushrooms. Generally speaking, the corn black powder mushroom produced through the factory assembly line will be cheaper than the wild one, but it is also a relatively excellent product.
In terms of the domestic situation, most of the corn black powdery mushrooms we see in the market come from corn fields in Gansu, Hebei, Shaanxi, Xinjiang and other places. Although we are not yet able to achieve large-scale production in the factory, this also has the advantage that we now eat all natural products with higher nutritional value. Of course, it is not necessary in the future, because with the continuous rise in the domestic price of corn powdery mildew, many scientists have begun to overcome the large-scale production problem of this fungus, I believe that it will be effective in the near future, and it will be simpler for us to eat corn powdery mildew mushrooms.
Speaking of this, we can't help but sigh a little, that is, the material living standards of the people have indeed been significantly improved, and the time for China to discover the efficacy of corn powdery mildew is not later than germany, so why did Germany take the lead in achieving large-scale production, while China went to further cultivate corn seeds and prevent and control this disease? The reason is very simple, because most Of the Germans have achieved basic food and clothing needs, and for our country in the past, it was our real goal to feed all the people, such as the corn black powder fungus, which was born to destroy corn production, which we did not consider in the past.
But now it is different, with the improvement of social productivity, Chinese has generally solved the problem of food and clothing, in this case, China's scientists can naturally turn to overcome the problem of "large-scale production of black powder fungus", which is also a proof of China's national strength has been improved. I believe that in the future, there will be more and more things similar to "corn black powder fungus" that will be put into factories for large-scale production, and our country will become richer and stronger.
