In spring, the walnut trees are full of light green flowers like caterpillars, which are not beautiful. The newly born green buds set off the green flowers, giving them special charm and attracting many bees. From a distance, you will hear the buzzing sound and a lively scene. Walnut flowers are not beautiful, but they can be eaten. Mother dried it and ground it into powder, mixed it with flour, fried it or fried it into cakes. It tastes delicious and has the effect of treating headaches! The flowers are backward, and the palm-shaped petiole bears young fruits as thin as tadpoles, covering hundreds of trees. They are two in a row, three or four in a cluster, covered with branches, which makes people feel very happy at first sight.
In summer, the tall walnut tree is like a huge green umbrella, blocking the hot sun, and some branches extend to the tiles of my house, bringing a cool world to people. The old people in the stockade always like to move a chair, get together and chat, or play old brands; My childhood friends and I always like to play "playing cardboard" and "playing house" under the tree on weekends or after school. This has become our "happy base camp".
In autumn, the fruitful walnut tree has become an amusement park for children. Before its fruit is fully ripe, children will always be seen playing under the tree. They are looking forward to the wind and rain. Because at this time, walnuts will fall and let them eat. Every day before dawn, when I am still sleeping, I can always hear the children talking under the tree. The more it rains, the earlier the children get up! In the morning, you will see children with hats and hemp fibers, looking around under the tree with flashlights in their hands. Because they get something almost every day.
Soon after school starts every autumn, it is the season to harvest walnuts. At this time, the trees are very lively. Adults waved a long bamboo pole on the tree and crackled, and walnuts fell to the ground frequently like hail. My mother and sister, wearing hats, are scrambling to pick up walnuts rolling around under the tree. The children in the stockade were moved by the sound, scrambling to gather under the tree from all corners, and their voices buzzed. They all cleaned up walnuts on the ground for their hosts. Adults have long known the children's worries. Praise: everyone's efforts have paid off! Hearing this, the children competed with each other, even risking being hit on the head by walnuts and picking harder.
After the harvest, the adults distributed "prizes" to the children present one by one, and everyone passing by had a share. The children's wallets became bulging, with smiles on their faces, talking and laughing, and scattered alive. Some can't wait to taste the "trophy"; Others are busy cleaning up the "battlefield", hoping for new gains. The walnut tree is full of treasures, and it gives its whole body selflessly to people.

Therefore, walnut can be used as a high-quality tree species for greening barren hills, soil and water conservation and building soil and water conservation forests. But also a "cash cow" for farmers to increase their income and get rich. In addition to eating walnut fruit at home, my mother took it to the market to sell it in exchange for some daily necessities. Walnut trees also bring hundreds of yuan to my family every year. In that era when food and clothing were still a problem, it simply became a veritable "cash cow" in my family, adding a lot of color to our lives. It also brought endless happiness to me and my childhood friends! Later, because of the job transfer, our family moved to the county seat. Now, it's almost twenty years. Although I have been away from my hometown for so many years, I miss the walnut tree more and more. I don't know what it has become now. Is the lively scene under the tree still there?
In the midsummer of 20 12, my cousin in the country told me that the walnut tree was cut down. Because of the new rural construction, the roads in the village have been hardened and widened, and the walnut trees have to be sacrificed! When we got back to the stockade, all we saw was a huge tree pocket, lying alone on the roadside. Regret and helplessness arise spontaneously! Unfortunately, the walnut tree didn't even leave a photo!
I miss the walnut tree, because it has a spirit of silent dedication without asking for anything in return. Isn't this kind of state also a pursuit of our life? I miss my father who planted a walnut tree more, because he has the same personality as the walnut tree. He has been busy for his children all his life, and he hasn't even left a photo. It has been thirty-two years since his father left us. However, his earnest teaching often echoes in his ears: "If you want to walk well, you can drive by yourself, if you want to eat fruit, you can grow it yourself."
My father and the walnut tree brought me and my childhood friends a rare "luck" and a lot of happiness, but now my father and the walnut tree have become unforgettable memories! The tall image of my father and the walnut tree will be engraved in my memory forever, and nothing can be erased!
