was about to go to the greenhouse where sweet potatoes were planted, but he didn't expect Wei Zheng to stop suddenly, pointing to the field next to him and asked in surprise, Li Xiu followed his fingers and looked at it, only to see that the field was full of vegetables the size of a human head, it was Li Xiu who finally came up with Chinese cabbage, after getting two hybrid seeds this spring, Li Xiu planted them here separately, one of which successfully grew into Chinese cabbage, and the other failed, it looked more like kohlrabi, and it was much smaller. Pen, fun, and www.biquge.info

"Hehe, that's called Chinese cabbage, it's a kind of vegetable that is crossed with small cabbage and kohlrabi, which is not only many times bigger, but also can be stored in winter for a winter without rotting, just like white radish!" Li Xiu said with a smile that Li Xiu is also very proud of the Chinese cabbage he cultivated, and he may be able to mix it with a title like "the father of Chinese cabbage" in the future.

"There are such vegetables, but what is hybridization?" Wei Zheng couldn't help but be surprised when he heard this, and then asked with some puzzlement, he thought that sweet potatoes and corn were shocking enough, but he didn't expect Li Xiu to have something unexpected here.

"The so-called hybridization is actually to pollinate two plants with each other......" Li Xiu briefly explained the principle of hybridization, and also used the cross between horses and donkeys to give birth to mules as an example, so as to make it easier for Wei Zheng to understand.

"I see, Li Xianjiu is really knowledgeable, and he has been taught here!" After listening to this, Wei Zheng couldn't help but show an expression of admiration to Li Xiu again, he knew that Li Shimin attached great importance to Li Xiu, and wanted to win him over and over again, in contrast, the prince was a little lukewarm to Li Xiu, and after a failed wooing, he never paid attention to Li Xiu again, after all, there was no shortage of staff around the prince, but now it seems that Li Xiu's talent is far from being comparable to ordinary staff, so Wei Zheng also secretly made up his mind at this time, and he must persuade the prince to change his attitude towards Li Xiu after he goes back.

Wei Zheng was very interested in this Chinese cabbage, and immediately walked over and touched these Chinese cabbages with his own hands, and found that the cabbage grew very strong, and it was estimated that a cabbage would have to be two or three catties, and this was not fully ripe, and it might be heavier in the future. This discovery also made Wei Zheng stunned again for a while, and he didn't know what he was thinking in his head?

"Li is a great talent for sacrificing wine, isn't it a pity to only hold the idle position of sacrificial wine?" After a long while, Wei Zheng suddenly spoke.

Li Xiu was also immediately alert when he heard this, and after thinking about it, he replied with a smile: "Wei Xima is serious, I'm used to being lazy, it may be okay to let me do some farm work or something, thanks to the princess's refusal, let me take the position of sacrificial wine has already promoted me, as for what other official positions to do, I'm afraid it's really incompetent!" ”

Hearing Li Xiu's words, Wei Zheng just smiled and didn't say anything, but this made Li Xiu's heart even more vigilant, Wei Zheng is a well-known tendon, if he makes up his mind, I'm afraid he will never give up easily.

After arriving at the greenhouse, Wei Zheng's officials measured it again, and at this time Wei Zheng looked at the structure of the greenhouse with great interest, now the weather is hot, the silk and straw mats on it have been lifted, and there is naturally no need to raise the fire inside, but the overall structure of the greenhouse has not changed, so after Wei Zheng looked at it for a long time, he really let him understand the structure of the greenhouse.

"Li Saijiu, this greenhouse uses fire to raise the temperature inside, is it possible that after the temperature comes up, the vegetables in the greenhouse can grow normally?" Wei Zheng asked curiously at this time, he didn't eat less vegetables from the greenhouse in winter, and he also heard about the greenhouse in Princess Pingyang's house.

"The greenhouse is indeed a very important reason, in addition to sunlight, the silk covered in the greenhouse needs to transmit light better, but can not let the heat run out, sometimes the sun is very good, and it is not too cold, but also to uncover the top to let the vegetables bask in the sun, so that the vegetables can grow normally!" Li Xiu opened his mouth to explain.

"I see, no wonder you can provide so many vegetables in winter, but your vegetables are also too expensive, except for a few powerful people, I'm afraid it will be difficult for ordinary people to afford to eat, so can you lower some prices?" Wei Zheng nodded first, and then said with some complaints.

"Wei Xima thinks too simply, there is a need to burn fuel in the greenhouse, and a lot of labor is used, which will increase the cost of vegetables, so even if I want to reduce it, it is impossible to operate at a loss!" Li Xiu made a helpless expression at this time and said, of course, what he said was a bit exaggerated, even if the cost is added, the income of greenhouse vegetables in winter is more than two or three times, and this is the reason why Princess Pingyang has repeatedly requested, otherwise he and Ma Ye would have raised the price to more than five times the cost.

"This ...... It's true, but after the promotion of the cabbage of Li Saijiu, the people of Datang will not worry about having no green vegetables to eat in winter! Wei Zheng still didn't argue with Li Xiu, but proposed the promotion of cabbage, which made Li Xiu a little strange, when did Wei Zheng's temper become so good, could it be that the rumors he heard before were unreliable, in fact, he was a good person?

After those officials measured the sweet potato field, Li Xiu explained to them the places that need to be paid attention to in sweet potato planting, in fact, sweet potatoes are originally solid, throwing a sweet potato vine can survive on the ground, and it is not comparable to ordinary crops to cause diseases and disasters, the only thing to be afraid of is the insects underground, Li Xiu remembers that many of the sweet potatoes harvested when he was a child have traces of being bitten by insects, so when not planting sweet potatoes in winter, it is best to turn over the field, and you can freeze some of the eggs in the ground.

By the time Li Xiu finished speaking, it was already late, and seeing that it was about to get dark, he would definitely not be able to go back to the city, in line with the rule that those who came were guests, Li Xiu wanted to invite Wei Zheng and others to have dinner at home, and invited them to live at home tonight, but Wei Zheng refused, he had already said before that these officials temporarily borrowed to live in nearby farmhouses, in fact, most of them borrowed to live in Li's Zhuangzi, in Wei Zheng's words, they ate and lived with the people, and they could also learn some experience in planting corn from Liu Boss's tenant households.

In the face of Wei Zheng's old-fashionedness, Li Xiu had no choice but to personally send them to the Li family Zhuangzi, but he secretly told Boss Liu that there was no need to entertain Wei Zheng and these people, and he would give them whatever they usually ate.

Early the next morning, before Li Xiu got up, Wei Zheng came to the door again and urged him to visit Yang Nong together, which made Li Xiu have a headache. (To be continued.) )
