The suitable load is the load that can ensure the continuous and stable production of apple trees. It requires that fruits, branches and leaves reach a certain proportion. A large number of practical investigations have shown that the ratio of large fruit branches and fruits represented by Red Fuji is 4 to 5:1, and the ratio of leaf to fruit is 50 to 60:1. The ratio of medium-sized fruit to fruit is 3:1, and the ratio of leaf to fruit is 30-40:1. According to the above requirements, calculate the number of fruits to be retained, plus the insurance factor of 10% to 20%, which is the amount of fruit retained during actual fruit thinning. For example, if the red Fuji variety is planned to reach 3000 kg, the actual number of fruits to be reserved is (30005) + (3000510% to 20%) = 16500 to 18000 (pieces). After the amount of fruit retained is determined, the amount of fruit remaining per plant is determined according to the strength of the tree and the size of the canopy.

The above is the technical standard for apple thinning and fruit thinning during the fruiting period. In production, according to tree potential and cultivation level, Jiaodong fruit farmers generally require a yield of 2500-5000 kg per mu, and require a relatively large fruit. Generally, large-sized fruit is required to be more than 200 g, and medium-sized fruit is more than 150 g.
