The autumn fruit tree masters six points
Digging pits and digging tree pits should be fish-scale. The pit bottom should be flat and the depth should be beyond the length of the main root system. It cannot be dug into a pot shape. The diameter of the pit is larger than the diameter of the root of the tree so that the roots of the seedlings can be kept in the pit. Stretch. At the same time, the soil on the pit surface must be filled into the bottom of the pit. After fertilizing and digging tree pits, 50 to 100 kg of decomposed organic fertilizer should be applied to the bottom of tree pits, and some organic fertilizers can also be mixed during filling to meet the nutrient demand after the seedlings have survived. Be careful when raising seedlings and try to avoid damage to the root system. In order to facilitate planting, the main root can be trimmed slightly after emergence to facilitate the water absorption of the seedlings, thereby increasing the survival rate. When transporting seedlings over long distances, a mixture of yellow clay and one part water can be used to mix the roots of the mud and then wrap it up. Dipping seedlings Before planting seedlings, the roots of the seedlings can be immersed in a 1% concentration of phosphate fertilizer solution for 30 minutes. Phosphorus fertilizer solution with a concentration of 5% can also be planted. Seedlings treated in this manner will heal quickly and have a faster rooting. Planting seedlings should be planted in the center of a tree pit, which is 3 to 5 cm deeper than the original. When planting, shake the seedlings while filling the soil to fully extend the root system. After fixing the seedling roots, it is necessary to step on the soil and pour enough water once. Then, round the tree into round piles to facilitate wind protection and protection. Covered on the already planted fruit tree tray, used as straw, leaves, weeds, etc. to cover the tree plate, so that it can not only protect the alfalfa but also protect against cold, make it safe for winter, and increase the survival rate.
