As a greedy and sleepy cleanliness snake, although Xiaoqing has the ambition to contract out all the mulberries on the entire mountain, but it has a delicate figure, and after sweeping a few mulberry trees, it had to drag its full body back to Ganguyu's shoulders.

Gangu Yu wiped its mouth dipped in purple-black mulberry pulp for it, and Xiao Qing climbed up to Gangu Yu's head with satisfaction, crossed his body and began to rest.

Soon after, everyone also came back with handfuls of mulberries. Not only are their fingers dyed purple and black, but their lips and tongue are also a little black, and they look a little oozing.

"At first, I thought it was poisoned, but then I found out that it was actually stained. A villager smiled innocently, "But it seems that this color can't be washed off with water?"

"Wash it a few times, and it will be fine after a while. Ganguyu said with a smile, "By the way, did you notice just now which mulberry trees only bloomed and did not bear fruit?"

"Yes, there are quite a few such mulberry trees!" another villager immediately said, "There are still a small number of unripe mulberry fruits on the fruit-bearing mulberry trees, but some of the mulberry trees really do not bear a single fruit, I don't know why?"

"The reason is simple. Mulberry trees are male and female, dioecious, and male mulberry trees will naturally not bear fruit. Gangu Yu spread his hands, "But mulberry flowers are wind flowers, pollination is very convenient, a large mulberry forest only needs to leave one or two male mulberry trees, but now it seems a bit much." ”

A beautiful woman in a grass skirt hurriedly asked, "Do you want to replace some male mulberry trees?"

Gangu Yu nodded: "Naturally, it is to be replaced, but it is not to uproot it." The next thing we have to do is to cut down all this mulberry forest, leaving only the main trunk. ”

"All, all cut?" everyone was shocked.

"That's right, they all have to be cut down. Gangu Yu confirmed again. "This mulberry forest is planted by us using mulberry seeds, and it is called the mulberry, which is the wild mulberry. Wild mulberry has a well-developed root system, is drought tolerant and barren, and has strong adaptability to the environment. However, the leaf shape of most wild mulberries is relatively small and the mesophyll is thin. There are also many side branches, and they will grow to a height of several zhang to become arbor mulberry, which is not conducive to leaf picking and feeding white filaria. ”

When the villagers heard this, their faces were puzzled. One of them boldly asked, "Then why do we plant this mulberry tree, do we want to get this delicious fruit?"

"We grow leaf mulberry instead of fruit mulberry, and mulberry is just an add-on product for everyone to try. Ganguyu explained with a smile, "The main purpose of planting mulberry is to get their trunks as rootstocks. ”

"Rootstock?" The beauty in the grass skirt who has attended Mr. Gan's small class on crop planting is naturally no stranger to this term. "Should this mulberry tree be improved by grafting, like grapes?"

Gangu Yu smiled and nodded: "That's right! The advantage of grafted mulberry is that it can not only maintain the excellent traits of the scion, but also enhance the vitality of the plant with the help of the developed root system of the mulberry." In the future, when breeding mulberry seedlings of good varieties or rejuvenating old trees, it is necessary to use mulberry trees propagated by grafting. ”

Seeing that the villagers were at a loss when they heard words such as grafting, rootstock, and scion, Gan Guyu didn't explain more, but directly commanded: "So." Next, although we will cut off all the crowns of the mulberry trees, the severed branches cannot be discarded at will. Male mulberry branches are grouped together in one place for later use. Those branches of the mulberry trees with large and thick mulberry leaves should be sent to me as soon as they are cut down. As for those mulberry trees that do not grow well, and the mulberry leaves are small and thin, you can keep the mulberry leaves, and the branches that are cut down are useless. ”

The crowd nodded. I went back to the mulberry forest again and got busy. Gangu Yu, who has grafting experience, and two beautiful women in grass skirts instructed the villagers on how to select and cut the scion.

In order to maintain the vitality of the scion as much as possible, Gangu Yu removed the mulberry leaves as soon as he took over the scion, leaving only the strong buds, and then put them in the portable warehouse for preservation. Some of the thick mulberry branches were also collected by the Gangu rain. These things can be sold as raw materials for the wand body, and they can also make a small profit.

After everyone had finished preparing the rootstock and scion for the mulberry forest, Pei Pei and Lena also happened to return with another group of villagers. So Gangu Yu Peipei and the four beauties in the grass skirt were divided into four groups and began to teach the villagers how to graft.

There are many ways to graft mulberry trees, but the success rate of root grafting or bud grafting is highest in the dormant period of mulberry trees in winter or early spring. But it is currently a hot summer, if it is not for the mulberry tree that has strengthened its vitality, and with the assistance of the growth of all things, Ganguyu would not dare to graft at this time.

Therefore, he chose to graft the branches by bag grafting and splitting method. Splitting is a natural way to cut a hole in the rootstock and insert the cut scion into it to fit tightly.

At the same time, Gangu Yu also asked the villagers to insert the shaved scion between the mulberry bark and the wood, add some fine soil to the wound, and finally tie the grafted wound tightly with plastic film. By combining this method of splitting and bagging, each mulberry tree is grafted with more than three scions.

In order to improve the success rate of grafting, Ganguyu asked the villagers to use useless mulberry branches to practice scion cutting, and finally carried out practical operations. At the same time, he also ensured that there was a scion on each mulberry tree that he or Peipei had grafted in order to achieve the greatest success.

After increasing water and fertilizer again, Gangu rain smashed down the growth scroll of all things. It is worthy of a mulberry tree that has been strengthened by a seed and seedling incubator, and he is very satisfied with the success rate of grafting. With the exception of some of the grafted scions, which were severely defective, most of the branches quickly re-branched and leafed, and none of the scions on the mulberry trees were completely wiped out.

The villagers of Bath Village had never seen this technique before, and they were shocked for a while, thinking that it was a miracle. What's more, he knelt down directly in front of Sang Lin, chanting that the Mother of Nature is above, and his expression was extremely reverent.

Only Lena was not surprised, hugged Pei Pei and whispered: "This group of fellow villagers obviously participated in the whole grafting process, but they gave all the credit to Mother Nature. Your power to spread the faith is not small!"

"What's so unreasonable about this?" Pei Pei chuckled softly, "It's precisely because they have personally participated in the grafting, and at the same time they know that if they had done this before, they would not have achieved this effect at all, so they think that this is a miracle of Mother Nature." Besides, that guy also said that grafting technology was originally given by Mother Nature, and it would be a miracle to say it!" )
