The yield of wheat per mu is 1,800 catties, or the yield of wheat per mu is more than 1,800 catties, which is a gimmick used by many "seed sellers".
@北方农村网科技顾问团从事农业30多年, I really didn't believe that any wheat variety could really yield 1,800 catties per mu.
On the contrary, the easier it is to reduce the yield of wheat varieties, the more bragging and boasting, as shown in the following figure:
The "unmoving" yield of a certain wheat variety is a record of high yield, but the actual yield per mu of farmers is not as good as that of other local varieties -- even the "braggart company" claims that the yield per mu is "halved", and the farmers cannot achieve it.
Among the farmers and growers, of course, there are many farmers with high-tech quality, just like the following video, Lao Zhang, Youluyou Cooperative, Juye County, Heze, Shandong Province, according to 2.7 kg of wheat grains spread one square meter (666.6×2.7 = 1800 kg per mu). Let's see, which wheat variety can have such grains per square meter?!

Yes, the yield per mu is 1800 catties, and the grain weight of a single spike approved by a certain variety is about 1.7 grams (the number of approved grains per ear is × 1,000 grains), and about 800 ears of barley are needed (please note that they are all large ears, and there can be no small ears).
Do you visit any wheat variety, is there really one?
In fact, the "food security" of the Chinese nation comes from increasing production:
Or "water and fertilizer saving" to increase the yield of 200 catties to 300 catties per mu, or the same fertilizer and water to increase the yield of 200 catties per mu, this is the "practical thing" of benefiting the country and the people. This is information from the National Extension Center.
If you want wheat to increase the yield by 200 catties per mu every year (regardless of any year), you need "more ears per mu" (subject to the approval announcement) and "1000-grain weight" (subject to the approval announcement), the larger the spike wheat variety, the easier it is to reduce the yield (low spike per mu + low 1000-grain weight, or even "black and small grains"). #揭露农业伪科学 ##农业真科技##小麦真科技#
By the end of April, some so-called "big spike" wheat varieties had "withered white ears" - because of rhizome rot diseases, which not only made it difficult to produce high yields, but also became "the joke of the whole village" because of the reduced yield.
