In winter, it is a suitable period for planting flowers and trees during the dormancy period. However, if a certain part of the process of raising seedlings, transportation, transplantation and management is not properly handled, it will affect the survival rate of transplants and cause undue losses. Lifting preparation: One week before lifting, adequate water supply is provided to prevent dehydration. Especially for seedlings that have not been replanted for more than two years, the fibrous roots are very few. When raising the seedlings, they should be irrigated one week in advance. For the topsoil, watering can hardly penetrate deeper. The water penetrates each root group of the plant, so that the body can make up the water, so as to avoid premature dehydration after seedling and affect the survival rate. Prevention of pests and diseases: Seedlings that grow in warm areas, where diseases and insect pests continue to multiply, for this purpose, a broad-spectrum insecticidal sterilizer with contact, stomach, systemic, and ovicidal functions should be used before lifting. 40% iridfos- phate and 50% carbendazim or thiophanate mixed 1000 times, spraying once. Before the seedlings were lifted, “spoiled manure†was sprayed to improve resistance and adaptability. Generally used potassium dihydrogen phosphate, multi-leaf fertilizer, photosynthetic fertilizer and other mixed, sprayed 1000-1500 times. Carefully raised seedlings: After the soil ball is incomplete and the root group has many wounds, the paste-like yellow mud pulp is used to pack the roots. When packing, use wet straw to wrap one layer first, then wrap it with plastic film and tie it with rope. Preparation before planting: After receiving the seedlings, they should be unpacked as soon as possible. The seedlings should be erected and removed. Cut off the branches with long branches, old and sick branches, and dense and weak branchlets in the crown. The large wounds are sealed with wax. Then use potassium dihydrogen phosphate, multiple leaf foliar fertilizer or plant power 2003, leaf noodles. Digging acupuncture points: The pH value should be measured in the loquat area, and Gaza should be added to the abundance. The poor soil should be filled with fertile soil to carry out soil improvement. Where the hole is sand, it should be filled with a 30 cm thick yellow mountain mud with good water retention performance. If the hole is low and the drainage is poor, a drainage ditch should be drilled, followed by pebbles, coarse sand, and fine sand. The hole should be filled with water first, then some straw and loose fertile soil. Planting: planting should pay attention to the original planting in order to make the plant better adapt to environmental conditions and improve the survival rate. For the seedlings with incomplete soil ball, the root groups have been dehydrated to varying degrees and need to be immersed in ramie pulp (2% potassium dihydrogen phosphate, 2% white sugar, 1% vitamin B12, 95% yellow mud)蘸 Miao root planting. The root seedlings were placed in caves, aligned with the original direction, and the roots were straightened out. Half the amount of soil was filled in, and the roots were lifted slightly. Sprinkle the water, and then fill the soil to the surface 5 cm away from the hole, compaction, pouring enough water. Post-plant care: single plant large seedlings planted in large holes, after the planting, the use of wooden sticks to support the binding, in order to prevent wind and shaking affect the root and soil adhesion and affect rooting. When the topsoil is white, water it in time. In areas with frost, the soil surface of the hole should be covered with straw insulation, and the main pole should be tied with straw rope to prevent cracking. The crown should also be covered with a plastic film and tied with rope.
