Saplings changed to pick in the northwest
Spring is the season when many fruit trees are eliminated. When selecting trees, they should be selected in the right direction. It is recommended that the scion should be chosen in the direction of the northwest of the rootstock rather than in the northeast because the northern and southern winds are often scraped in the April and May of Beijing. The scion is in the northwest direction of the tree just in the downwind direction, while the northeast is in the upwind direction. After the scion survives, if it is not settled in time or the buds are not fixed properly, it will be easily blown by the wind. If a sapling only receives one scion, this situation will be delayed for one year. This will not only affect the income of the fruit, but also cause the tree to grow unevenly. (Su Wen)
