The so-called black cow is the name given by the people of Xincuicheng for this kind of livestock. In fact, this is also an animal that is only found around New Emerald City.

It is said that the ancestor of the black bull is a low-level demonic beast, but after a long period of artificial domestication, this demonic beast has degenerated, and gradually lost the ability of the demonic beast, and even the magic crystal is no longer condensed, and it has completely become a kind of livestock, which is the black bull in front of Ganguyu.

Unlike black chickens, which can lay white eggs and white chickens that can't lay black eggs, this kind of cow creature that can produce black milk is still dark all over, with short, hard black hair shiny, worthy of its name as a black cow. The appearance of the black cow is not much different from the cow in Ganguyu's cognition, it is worth mentioning that even if the black cow in front of him at this time is a lady, the pair of horns on its head is still not small.

"Oh, do you mean its horns?" Ye Bin introduced, "The horns of the black bull will continue to grow, so we will see them off regularly, otherwise they will be weighed down by the weight of the horns. ”

"What about the sawn off horns?" asked Ganguyu hurriedly, "You won't throw it away, will you?"

Ye Bin was stunned: "Otherwise?"

Gangu Yu lifted his forehead: "It is recommended that you take some samples of black horns and send them to the Medicine Elder of the Natural Forest and the Autumn Mentor of the Cyprus Magician Academy, maybe there will be a surprise." ”

When Ye Bin heard this, a hint of realization appeared in his eyes, and he immediately nodded.

Gangu Yu circled around the black cow in front of him twice, and suddenly asked, "Is this black cow mainly milked and eaten?"

Ye Bin replied: "Although the milk production of black cattle is not high, everyone mainly takes milk for consumption. Its meat tastes good, but no one will kill a cow to eat meat unless it is absolutely necessary. In this wave of demon locusts, some black cattle were bitten to death by demon locusts, and some were starved to death. Only a small number of villagers could not protect themselves, so they had to kill and eat. ”

"If you only take milk, then the input and output of raising black cattle are not very disproportionate?" Pei Pei wondered.

"So the number of black cattle in our new green city is not high. Ye Bin explained, "The principle we follow is that we can raise as many black cattle as there are wheat stalks, so it doesn't mean that there is too much additional investment." ”

Gangu Yu suddenly asked thoughtfully, "Then how is the breeding ability of this black cow?"

"Why did you suddenly remember to ask this?" Ye Bin was stunned. "Hmm...... Let's just say that there are usually only two or three bulls in the whole of Emerald – one is more than enough, but in case the bulls get sick or die unexpectedly, we keep extra bulls in isolation as backups. And even so, we need to be careful to control the number of black cattle, otherwise we will be eaten by the black herd. ”

"In this way, this black cow's harem is full!" Gan Guyu said with a smile, "Then how long does it take for this black cow to grow to maturity?"

"It's about eight months, if the feed can keep up. Ye Bin replied. "At the same time, black bulls have a very short gestation period, about four months. ”

Gan Guyu smiled lightly: "Since that's the case, it's easy to do." ”

Xiaoyu Yixi: "Have you thought of a way?"

Gangu Yu smiled and nodded: "Although I don't know why this kind of black bull can only survive near Xincui City, they should be the greatest gift from Mother Nature to Xincui City! ”

"What do you mean?" Ye Bin hurriedly asked.

"There seems to be only one factor that restricts the scale of black cattle breeding in Xincuicheng, and that is the amount of feed supplied to them. Gangu Yu spread his hands and smiled, "Then as long as their food problem can be solved, it will definitely be feasible to breed a large number of black cattle, right?"

"I understand!" Ye Bin's eyes suddenly lit up. "There really isn't much good land to grow crops," he shouted. But if we can grow black cattle feed on barren land where crops cannot be grown, won't we be able to alleviate the food crisis by raising a large number of black cattle?"

"It's not more than that. Gangu Yu said with a smile, "Black milk is so delicious, once it gets out of Xincui City, its value may have to multiply several times." Maybe Xincuicheng will rely on it to make a fortune!"

"So to speak. The question now is whether it is possible to grow black cattle feed on saline soil. Xiao Yu clapped her hands and smiled, "And the answer is obvious, Xiao Guyu, you have a way, right?"

"All I can say is that I already have some ideas. Gangu Yu spread his hands and smiled, "As for whether it can be done." You'll have to experiment first. ”――

The northern suburbs of Xincui City.

"The anti-salt in this area is quite serious. Xiao Yu pointed to the saline land in front of everyone and said, "It's enough for you, right?"

Ganguyu nodded: "It's just a trial planting, or you won't be able to plant such a large area." With that, he took control of the earth elemental and began to plough the land in front of him.

Because it is saline-alkali land, Ganguyu consciously deepened the soil, and then made the top soil layer as fine as possible, and then began to sow seeds.

Considering the problem of universality, this time the seed Gangu rain only optimized the immunity to pests and diseases, and began to be sown on demand. Because there was no guarantee that the germination rate would still be 100 percent, Gangu Yu planted five or six seeds in each seed hole, with a row spacing of about two feet, a plant spacing of more than half a foot, and a depth of only an inch, and then poured rooting water.

For the first time everything grows, Gangu rain only lasts until the seedlings in the field grow to a foot tall and then stops, and then he leads everyone to start the work of fixing and replenishing seedlings.

In the past, five or six seeds were planted in each hole, but now there are three or four seedlings growing in the holes, while others have no seedlings at all. Therefore, they need to leave the strongest one among the holes where there are many seedlings, pull out the rest, and do a good job of replanting the holes that have no seedlings to germinate.

After doing this step, Gangu Yu applied some farm manure to the field ditch. There are two reasons for this, first of all, it is better to apply acidic fertilizers to saline-alkali land, not alkaline fertilizers. Secondly, in Ganguyu's vision, in the future, these saline-alkali lands will inevitably rely on well-rotted black cow manure to improve.

Then Gangu Yu smashed a scroll of all things growth into this field again. Tanaka's seedlings, which were still somewhat similar to wheat, quickly grew taller than everyone else, and then the heading began. During this time, Pei Pei watered the field three more times, and together with the others, removed the tillers that were not growing well for the crops in the field, and also carried out a tillage to cultivate the soil to strengthen the seedlings and prevent lodging.

In the end, everyone looked at this crop with a height of nearly one zhang and a burgundy spike on the top, and couldn't help but sway. This is saline-alkali land, and it can grow such tall plants!

"This, this is sorghum?" Pei Pei suddenly remembered a wine-making crop that Ganguyu had planted in the mountains behind the natural forest, which seemed to be very similar to the crop in front of him.

"It seems to be sorghum?" Xiao Yu also asked uncertainly, "but this sorghum rice seems to be smaller...... In any case, it is very good to be able to bear fruit on such a barren land! But Xiaoguyu, this sorghum is for the black cow to eat?"

"To be precise, the stalks and leaves are for the black cow to eat, and this sorghum rice can naturally be eaten by the people, and of course it can also be used to make wine. "But this is not ordinary sorghum, but sweet sorghum." You can also call it sorghum cane, because it grows sorghum on top and sugar cane on the bottom!" )
