First, dig pits. The excavated tree pit should have a fish scale shape. The pit bottom should be flat, the depth should be beyond the length of the main root system, and the bottom shape of the pot should not be dug. The diameter of the pit should be larger than the diameter of the root system so that the seedling root system can be stretched in the pit. It is also necessary to fill the pit surface soil into the bottom of the pit. Second, fertilization. To dig a tree pit, apply 50--100 kilograms of decomposed organic fertilizer to the bottom of the tree pit, or mix some organic fertilizer during filling to meet the nutrient requirements after the seedlings have survived. Third, raise seedlings. Be careful when raising seedlings to avoid damage to the root system. In order to facilitate planting, the main root can be trimmed slightly after lifting, which is favorable for seedlings to absorb water and improve the survival rate. For long-distance transport of seedlings, a mixture of yellow clay and one part of water can be used to mix the roots of the mud and then packaged. Fourth, soaking seedlings. Before the seedlings were planted, the roots of the seedlings were immersed for 30 minutes in a phosphate solution with a concentration of 1%, or the phosphorus fertilizer solution with a concentration of 5% on the seedlings was planted. Seedlings treated in this manner will heal quickly and have fast roots. Fifth, planting. The saplings are planted in the center of a tree pit, and their depth is 3-5 cm deeper than the original. When planting, shake the seedlings while filling the soil to make the roots stretch and bind with the soil. After the roots are fixed, they should also step on the soil and seal the soil, and pour enough water once to set the roots. Lee wind and security. 6. Coverage. On the planted fruit tree tray, it is used as straw, leaves, and weeds to cover the tree tray. This will not only protect the alfalfa but also prevent cold, make the seedlings safe for winter, and have a high survival rate. China Agricultural Network Editor
