No matter what variety of neighbor the land is, anyway, the wheat of his family (hers) is not as good as yours every year, which is the best proof of your family's "high scientific and technological quality".
Secondly, no matter what the year, your wheat is always better than that of your neighbor's, which means that your scientific and technological quality is "okay".
Again, you chase high wheat yields every year, but sometimes the yield is higher, and sometimes the yield is reduced, which shows that your family's scientific and technological level has huge room for improvement.
As the old saying goes: Be prepared for danger in times of peace, be prepared when you think, and be prepared.
Moreover, the core idea of "The Art of War", one of the most influential classic books in the world, is that it is "invincible" first, and then "better than the easy one".
Used in the selection of wheat varieties, are you sure that the wheat varieties you choose are [resistant to reduced yields]?!
If you choose a wheat variety that is not "resistant to reduction", of course you will be prone to a reduction in yield – even if you don't cut your yield in 2024, who can guarantee that variety won't cut in 2025?!
There are a few "bottom lines" for choosing wheat varieties that are "resistant to reduced yields":
1) Varieties with low panicle formation rate ("sparse in the field" varieties) cannot be selected.
Because, one is not conducive to high yield, and the other is that it is easy to reduce yield because of "underdeveloped root system".
2) Varieties with small grains (varieties with too low 1000-grain weight) cannot be selected.
Because, first, it is not conducive to high yield, second, the root system is underdeveloped, which leads to the reduction of drought resistance and dry and hot wind resistance, and third, it is easy to cause rhizome rot diseases.
3) Approved disease resistance identification, too many varieties of "high susceptibility" can not be selected.
For each additional "highly susceptible disease", there is a double risk of reduced production due to the disease.
4) Varieties that are too serious in the field to "wither trees and dead ears" cannot be selected.
In any wheat variety, once the "dead trees and ears die" occur due to rhizome rot, not only the wheat yield is easy to be reduced, but also the next crop of corn rhizomes rot and "corn wilt" or "corn wilt".
5) Varieties that are not resistant to "double rust" cannot be selected.
Because, once the rust breaks out in 2025, the reduction of your wheat yield is only a gap between "more yield reduction" or "less yield reduction", and it will definitely not reduce production.
6) Late-maturing varieties cannot be selected.
Because late-maturing varieties are most susceptible to hot and dry winds, but also to hail, at least the 1000-grain weight is low, and the kernels are small (or even black).
7) Varieties that are not drought resistant cannot be selected.
Because the biggest root cause of wheat varieties that are not drought resistant is "bad root system], which is not only not conducive to high yield, but also significantly "pulls down resistance" in terms of resistance to dry and hot wind and frost resistance.
8) Varieties with too low bulk density cannot be selected.
The grain bulk density of wheat is high, which is the best proof of good grain filling.
Why is the grout good?! Of course, it is a good root system and good resistance in many aspects.
For example, the "Baoyan 12" bred by the regular Academy of Agricultural Sciences, with an approved grain bulk weight of 829 g/L, is a "model for everyone to learn".
