When the carriage passed by Yichunyuan, Li Xian's eyes revealed not only disdain but even some disgust.

After the two returned to Bao'an County and had another meal with Fang Zhao, they set off directly back to Linyuan County. Anyway, Wang Zhen and Wu You had only been out for more than ten days, so there was no way they would come back so soon. There was nothing wrong with staying here. After getting the money, they naturally had to go back.

It took more than two days to get here, and it would take more than twenty days to go back. Li Xian looked at the boat moving forward ten feet and backward five feet, and he grinned, not knowing how to comment.

Wang Pingan handed him a handful of lychees, spit out the lychee pits in his mouth and said with a smile: "Be patient, this is how it is when you go up the river. After all, the river here is not wide, so you dare not sail with full sails."

Li Xian nodded, peeled a lychee and ate one, then sighed and said, "In fact, if we don't have any goods with us, it should be faster to go by land."

"The land route is indeed faster, but not by much, and it is much more difficult than the water route."

Li Xian curled his lips and said dissatisfiedly: "Lingnan is already making so much money, and I don't know when the official roads can be repaired again. If they are all repaired into smoother cement roads, traveling by land will not be so difficult."

"almost."

Wang Pingan took a look and said with a smile, "They specialize in selling large sugar canes. They sell them for the money they earn from planting one, so they naturally have to control the spacing."

Comparing these two aspects, it is very cost-effective for them to grow crops this way.”

Wang Pingan smiled and said, "One percent may not seem like much, but our Tang Dynasty is large. If you add it up, one percent of the output is not small. Besides, aren't Chinese cabbage and various fruits and vegetables also high-yielding? That also solves the food problem from the side. In addition, various livestock have been bred better because of their research, which can also save a lot of food.

“That’s different. For example, if one acre of land produces 10,000 kilograms of sugarcane, if they plant it this way, then those 10,000 kilograms are all large sugarcane. The yield of densely planted sugarcane is about the same, but you may not be able to pick out 5,000 kilograms of large sugarcane, and the quality is not as good as theirs.

After listening to Wang Ping'an's explanation, Li Xian nodded in understanding and then asked, "Don't they know to plant them sparsely when planting? Why are they cutting the bamboo shoots now? It's a waste of seeds and troublesome."

In fact, the two places are complementary in nature. Let’s put it this way, the gym only looks at the reaction of crops, while the farmers in Yuzhou need to find ways to popularize high-yield crops.

However, as the Yuzhou faction gradually penetrated into various parts of Lingnan, mainly the spread of various technologies, the process of Lingnan's prosperity was accelerated a lot. With the growth of population, more land would naturally be developed. Where there are people and land, the country will naturally become prosperous.

Wang Pingan shook his head and explained, "It shouldn't be. The gym is mainly studying the effects of various minerals and microorganisms on crops, while the farmers in Yuzhou are truly conducting comprehensive research on various crops.

Wang Pingan shook his head and continued to explain: "That's different. Even if the sugarcane seeds are selected, not all of them will germinate. This way, we can ensure the spacing after planting them closely and then cutting the shoots. Otherwise, it will be more troublesome to replant.

Wang Pingan thought for a moment and explained, “Lingnan actually pays more attention to commerce. Now that they have explored the coastal waterways, the cargo pressure has been resolved, and the repair of the land routes has mostly been put on hold.

Li Xian sighed, "I didn't expect that growing sugarcane would involve so many tricks."

Haha, my mother said that the first time she ate brown sugar, she ate brown sugar made from rotten sugar cane."

"Wouldn't it take 10 to 20 years?"

If theirs costs four jin for one penny, the one that is picked out will cost five jin for one penny, and the one sent to the sugar factory may cost seven or eight jin for one penny, and in some places it may even cost ten jin for one penny.

Li Xian looked around boredly and saw someone cutting sugarcane shoots on the shore. He asked curiously, "Their sugarcane shoots don't seem to be that dense. Why are they cutting some off?"

If we want to repair the official road, we probably have to wait until the whole Lingnan is prosperous. Well, it doesn’t have to be as prosperous as Bao’an County. Once it is as prosperous as ordinary counties in the Central Plains, they should consider repairing the official road.”

Their salaries are indeed very high, but compared to their achievements, that little salary is still very cost-effective."

When my father first planted sugarcane in Yuzhou, even though he asked people to buy and plant it, after it was transported to Yuzhou, 30% of it was still half infested with insects and half damaged. If you don't select it carefully, it will easily be planted.

Li Xian raised his eyebrows and asked, "It took them ten years to increase the yield of wheat and rice by a little over 10%?"

Li Xian frowned and said, "Won't it be a waste if their two places conduct overlapping research? Apart from anything else, those guys' salaries are very high."

Wang Ping'an nodded and smiled, "It's not easy to survive in this world. You have to be good at what you do. I only know a little bit about these things. There are people in the Taoist Hall and Yuzhou who specialize in this."

"Why do we need to grow sugarcane specifically?"

The current prosperity of Lingnan is limited to certain areas, mainly concentrated in the most prosperous areas around Bao'an County, and the next most prosperous areas are the Pearl River Basin and the coast. After all, the products must be easy to transport to be valuable, and prosperity will only come with money.

My father was very satisfied with their progress. He once told me privately that a 10% improvement in ten years would be good. Even if it doubled in a hundred years or two hundred years, it would be great. As long as we keep improving at this rate, sooner or later we will have more food than we can eat.”

Li Xian thought about it and nodded, "That's true. If Confucianism had not been promoted exclusively, and the situation had improved since the Western Han Dynasty, we would have more food than we can eat today.

Food is the foundation of a country. Even though the Tang Dynasty has stored so much food and bacon, my father and mother will still take out a portion of money every year to continue purchasing food and bacon.

As long as the underground warehouse is well built, it can store food for ten or twenty years without breaking down. Only by storing more food can the country be stable. After all, no matter who you are, as long as you are a human being, you have to eat. "

Wang Pingan nodded and smiled, "So, let's develop Nanzhao. We need to find minerals, plant crops, and raise pigs."
