Plum has a strong adaptability to the climate. As long as the soil is deep and has a certain fertility, it can be planted regardless of the soil quality. High requirements for air and soil moisture, extremely resistant to water accumulation, poor drainage in orchards, often causing rotten roots, poor growth or prone to various diseases. It is advisable to choose a place where the soil is loose, the soil is well ventilated and the drainage is good, and the soil layer is deep and the groundwater level is low.

Before planting, the base fertilizer should be applied, and the new high-fat membrane should be used for seeding. Plum tree is far from meeting the needs of its growth and development, so it is necessary to strengthen the management of fertilizer and water during the growing season. After planting, appropriate topdressing should be applied to supply growth and development. Combined with spraying of photosynthetic nutrient film fertilizer, photosynthesis productivity nutrients and chlorophyll can be increased, and plants can effectively increase their fertility. At the same time, plant cell immune factors are applied to enhance the plant's stress resistance and strong immune function, so that it has effective immunity to pests and diseases. Apply 1 quick-acting nitrogen fertilizer before germination or before flowering, and each planting water is about 1 kg, which promotes germination and flowering. During the flower bud differentiation period, it is necessary to use the wisdom control to promote the flower king to regulate the nutrient matching of the fruit tree growth, fill the vacuum of the lack of nutrient elements, adjust the size of the two-year-old flower in two-way adjustment (increasing the number of flowers in the small year, reduce the flower control in the big year), and suppress the excessive length of the branches to force the excess return. Flow to the fruit, promote flower bud differentiation and increase the level of fruit expansion.

The pruning of plum trees should pay attention to both the tree shape and the results. In the young Li tree, the main branch is selected and cultivated, and the plastic task is completed. At the same time, the tree is balanced, the master-slave relationship of the backbone branches at all levels is maintained, and the overstretched backbone branches are properly cut. After the pruning is completed, the general manager of the tree should be disinfected and sprayed with the plant hibernating culturing hibernating cytokine to produce a large amount of hibernating cytokines. The physiology system of the numbness wintering plant stops the movement, sleeps peacefully, recharges the essence, and protects the plant life gene survival. rate
