Netizens asked: can the yield of soybeans reach 1200 jin per mu? Such an output is virtually impossible.

Can the yield of soybean reach 1200 jin per mu? Many netizens commented that during the Great Leap forward, the yield of soybeans per mu was more than 1200 jin. In reality, it was only during the Great Leap forward. In today's normal field yield per mu experiment, such exaggerated figures are basically impossible to achieve. Why? Because we also have to follow the law of conservation of energy.

We should know that soybeans are made up of protein and oil, the ratio of which is about 8:2. Friends who have studied biology should understand that among the three major substances that store energy: sugar, protein and fat, especially protein and fat, protein and fat have the highest energy, that is to say, the energy required for the synthesis of these two substances is the highest.

The reason why the yield of crops such as millet corn and rice is higher than that of soybean is precisely because its synthetic storage material is starch (polysaccharides). Biologists' expectations of plant yield can basically be calculated through the model. In other words, the light energy received per unit area is converted by the energy (sugar) that can be converted by plant leaves after photosynthesis, which is converted into the yield of starch, that is to say, it actually has a lot to do with the weather. After all, photosynthesis on cloudy and sunny days is different.

However, at present, this calculation is still too ideal. after all, there is still a problem of conversion efficiency in the conversion of energy. But we can be sure that the yield of crops is determined by the limit, and when a certain limit is reached, it will not be able to continue to increase.

At present, the record of soybean yield in Missouri in the United States was 1388.5 jin / mu in 2007, and this record has not been repeated, and there is only one record in the world. But Xinjiang of our country once created the record of 811jin per mu, it can be said that the record of 1200 jin is difficult to surpass, after all, the current wheat has not been able to reach 1200 jin per mu.

If the dry matter yield of the crops that store sugar reaches 1200 jin per mu, soybeans may also be expected to achieve a breakthrough. However, in terms of current science and technology, it is difficult to surpass this record.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
