Fusuni smiled slightly: "This requires the efforts of craftsmen. ”

"Artisan?"

Brother Nine doesn't understand, what does this have to do with craftsmen?

Fusuni had already decided to let the Chinese nation avoid detours and walk on the right path as soon as possible, so as not to be left behind by the Western powers.

It's just that there are too many restrictions on women in this era, and with her own efforts, I'm afraid she can't change too much.

Seeing that Elder Brother Jiu was so interested at this moment, her heart moved, if she could let Elder Brother Jiu help, she might be able to get an unexpected gain.

So she elaborated: "Craftsmen are very important, and every progress in productivity is inseparable from craftsmen. For example, in agriculture, at the beginning, human beings only used stone tools, and it was very inefficient to cultivate land or harvest. Later, bronze and iron tools were used, and the efficiency was naturally greatly improved. There are also the invention of various agricultural tools, which also improved the efficiency of farming, which is also inseparable from craftsmen. ”

"Let's talk about the traffic I just mentioned. In the beginning, human beings relied only on two legs, but later they invented horse-drawn carriages and boats, which not only increased the speed, but also increased the load, which also did not depend on the craftsmen. ”

Brother Jiu suddenly said: "There is some truth in what you say, it's just that craftsmen have invented and improved agricultural tools, although they can improve farming efficiency, but there is still no way to increase food production." Improving transportation and speeding up the exchange of materials between various places can only treat the symptoms but not the root cause......"

Fusuni couldn't help but shake her head when she remembered what she knew about the current yield of grain per acre.

At the time of her previous life, the average yield of rice per mu was more than 400 kilograms, and the highest was nearly 1,000 kilograms. The average yield of wheat per mu is more than 300 kilograms, and the highest yield can reach 800 kilograms.

At present, the yield per mu of rice is less than 200 kilograms, and the yield of wheat per mu is more than 100 kilograms, which is far lower than the yield of later generations!

Fusuni sneered, "Who said that food production can't be increased? ”

Brother Jiu was suddenly shocked: "Do you have a way to increase grain production?" ”

Brother Jiu knows very well that the reason why Khan Ama attaches so much importance to agriculture is because there are still many people at the bottom who have not solved the problem of food and clothing, and these people are the hidden danger of national turmoil. If you can make the people of the whole country fed and clothed, then this feat is enough to surpass the Qin Emperor, Han Wu, Tang Dynasty and Song Ancestors!

Fu Suni didn't answer Brother Jiu's question directly, but said, "I heard that there are many famous flowers in the Imperial Garden. ”

Brother Jiu was stunned for a moment, not knowing why Fu Suni changed the topic, but he still suppressed the anxiety in his heart and replied, "Yes." What flowers do you like? How many days will it be your birthday, and how many pots will I give you then? ”

Fusuni gave him an angry look: "I didn't ask you to spend it!" You should also know that many of today's precious flower species are artificially cultivated. If flowers can be cultivated, why can't food be cultivated? ”

Brother Jiu was shocked: "You mean...... Are you saying that grain can be bred into high-yielding grains from different varieties like flowers? ”

"Yes, you can use different varieties of the same subject for crossbreeding. For example, wheat, some wild wheat ears are large, but the shell is empty, so after crossing with the planted wheat, will it not be empty on the basis of the large ear? And wild wheat is more tenacious, after hybridization, can it improve the vitality and insect resistance of planted wheat? ”

"In this way, the best seeds are selected for breeding from generation to generation, so that after a few generations, you may be able to get a high-yield grain seed. Of course, this is a long process that requires constant financial support and patience. ”

"Again, the fertility of the land is not enough, which will also affect food production. There is a big difference in yield between the upper and lower fields. So, is there a way to improve land fertility? Is there any way to make Shimoda become Ueda? These are all things that can be studied! ”
