Chinese all know a saying: if you are not afraid of not knowing the goods, you are afraid of comparing goods.
The same is true for wheat varieties: there is a control variety at the time of approval, and a certain increase in yield must be required to pass the approval. It's the rule.
However, some seed companies that are "eager to make money" boast of high yields when selling wheat seeds, "Zhang San" boasts of a yield of 1,800 catties per mu, and "Li Si" boasts of a yield of 1,900 catties per mu, but none of them are true.
Even some people are suspected of "agricultural production fraud" and boast of varieties of profits (Xinhua News Agency's "Half Moon Talk" has exposed the inside story), who knows, they are false propaganda, suspected of fraud, see the following picture Ren Xiaodong's lawyer's comments.
Please pay attention to one fact: for any wheat variety in the "yield measurement report", how many catties of wheat does the farmer actually produce per mu?
No matter how good the figures in the "yield measurement report" are, what is the value of wheat varieties that cannot increase the actual yield of the peasants by several hundred catties per mu compared with their neighbors?
In fact, the more vaunted the wheat variety, the more likely it is to reduce the yield (the variety is not resistant, and the kernels are black and small), as shown in the figure below.
10,000 "yield measurement reports" are not as good as a "wheat variety competition" - multiple wheat varieties are compared with each other, don't you know what is a "mule" and what is a "horse"?!
Please note a scientific principle: the "stable and high yield + significant increase in yield" of wheat comes from the "number of ears per mu" and "1000-grain weight"
However, if there are not many ears per mu and the weight of 1,000 grains is not high, no matter how big the ears are, it is a fool.
Please don't forget: with the same fertilizer and water input, wheat is adjacent to the land to increase the yield by 200 catties "is the right way"
Because, the National Agricultural Technology Extension Center has achieved a large area of "water saving and fertilizer saving" to increase the yield of 200 catties to 300 catties per mu, so we require the same fertilizer and water input, and the yield of wheat per mu increases by 200 catties, which is the minimum requirement, right?!#小麦真科技##农业真科技#
