"This way, when the branches secrete sap, it can flow from below and won't damage the buds."

Chen Suwen taught her followers how to graft little by little, starting with grafting large branches.

After all, most of these apple trees are old trees that are decades old, with relatively large branches, so we have to start learning by grafting large branches.

The buds she used weren't particularly large either. The apple seedling buds she cultivated weren't very big, but they were excellent for grafting.

"Make a cut high up on the sleeper; the purpose of the cut is to speed up the healing of the buds..."

Chen Suwen's movements were swift and efficient. When teaching people how to cut buds, she also reminded them to be careful so they wouldn't accidentally cut their hands.

Chen Suwen obtained the grafting membrane from the brigade through connections with higher authorities.

Although grafting technology is not particularly mature now, 71 years later, grafting membranes are still available, and although they are relatively rare, they can still be used.

Chen Suwen led her people to learn grafting techniques, from grafting large branches to grafting small branches and side grafting. After trying them several times, she finally managed to graft all the apple trees that the brigade had allocated to her.

It takes one to two years for the grafts to fully heal, and it also takes time for them to grow fruit.

After thinking for a while, Chen Suwen prepared a new type of fertilizer. The materials needed were very common and ordinary, and there were large quantities of weeds.

Of course, the potion that accelerates the decomposition of these materials is also very simple to make, and the ingredients are very common.

So the fruit trees in the brigade haven't produced much fruit yet, but the fertilizer formula that Chen Suwen came up with made the brigade decide to set up a fertilizer factory.

Making money by selling fertilizer is quite good.

The brigade had no objection to building a fertilizer plant; everyone wanted to make money. And the fertilizer formula that Chen Suwen presented did indeed make the crops grow very well.

Therefore, the whispers and murmurs of a few people in the brigade did not affect the brigade's decision, and the Guangming Brigade fertilizer plant was built.
