Why leave a scar on the walnut tree? Won't it be hacked to death?

Walnuts are delicious, but trees are hard to grow. Some walnut tree bowls are thick and fruitless, and some walnut trees have thick handles to bear walnuts. What's going on here? Cage saw some farmers cut many holes in the trunk of walnut trees. Aren't you afraid of dying walnut trees? It turns out that this is the most common pulp discharge in fruit tree planting technology. Then why put the pulp on the walnut? What is its purpose?

1. Walnut trees have strong adaptability and are widely planted as common fruit trees. There are many kinds of walnuts, including iron walnuts, walnuts, pecans and wild walnuts. Due to the differences of varieties and regional climate, the flowering and fruiting periods of various walnuts are slightly different. However, regardless of the flowering and fruiting period, some walnuts fail to bear fruit for a long time, which seriously affects the enthusiasm of tree planters. Experienced farmers can paste walnuts, while some people just grow and eat them themselves. They have little experience and need to know the technology of pasting walnuts.

The reason why walnuts don't blossom and bear fruit for a long time is related to the age. Walnut trees have a long life. There is a 70-80-year-old walnut tree (as shown in the figure below) in Kalopanax spinosa, which absorbs water and nutrients and supplies its roots, stems, leaves and other vegetative organs, making the tree prosperous and soaring.

Walnut trees only grow trees, and the reproductive growth of flowers, fruits, etc. is restricted, so that they bear fruit late and rarely or even not. Therefore, we must find ways to keep the balance and coordination between vegetative growth and reproductive growth.

Second, the pulping method If the walnut grows in a place with sufficient soil water and fertilizer, sufficient water and fertilizer and rapid nutrient growth, it can wait for an opportunity to block or slow down its vegetative growth. Pulping is a good way. However, walnut trees growing in dry land need to be cautious, and discharging pulp may cause walnut trees to weaken or even die.

Pulping is generally selected in May and June, and also after the fruiting period. The people who grow walnut trees here simply cut the exit on the trunk of walnut trees with a knife, and the position was chosen on the steps high from the ground. Of course, the incision should not be too deep, for fear of affecting the healing of trunk wounds. In fact, the cutting on the picture should be downward, that is, cutting from bottom to top to avoid water accumulation on the knife edge.

Thirdly, there are other ways to achieve similar goals besides drilling holes and discharging slurry. There are many wild walnut trees growing near the home of Catalpa spinosa, which are related to the walnut tree of seventy or eighty years old. At that time, I transplanted a lot of walnut seedlings, and one was planted next to the house. I tied the buffalo raised at home to the walnut tree for a while.

Buffalo is easily bitten by cows and mosquitoes on the open dam, so it often tickles the walnut tree and uses its horns to top the walnut tree. Strange to say, this walnut tree bears walnuts in the fourth year, earlier than other walnut trees transplanted in the same period. This may be because the activities of buffaloes have played a role in helping walnut trees to release pulp.
