First, planting 1. Soil treatment. The quality of the soil is directly related to the growth of the trees in the future. The physicochemical properties of the soil should be tested and analyzed. The pH, porosity, permeability, and water-holding properties should be analyzed and tested, and then the corresponding disinfection, basic fertilizer, and household soil should be taken. And other measures. In particular, the depth of soil excavation, the quality of the soil, the maturity of the basal fertilizer, the amount of fertilizer applied, and the flatness of the terrain must all meet relevant requirements. 2. The excavation of planting holes. The excavation of planting holes depends on the seedling root system, soil ball diameter, and soil conditions. In particular, the poorly soiled planting holes must be dug deeper, and then the basic fertilizer and the soil should be used to create a small environment conducive to plant growth. 3. Planting seedlings. Remove the non-perishable packaging with roots of soil seedlings. When planting, the bottom of the planting hole should be levelled, and the filling should be layered and compacted without leaving gaps. 4. Pouring water. Within 24 hours after planting, the rooting water must be poured. Second, maintenance management 1. Support: In particular, high green seedlings should be supported and fixed with positive triangle piles immediately after planting. Beware of dumping. The supporting point is about 2/3 of the height of the tree, and a protective layer is added to prevent skin damage. 2. Water control: Newly transplanted and green seedlings, the water absorption function of the roots is weakened, and the demand for soil moisture is small. Therefore, just keep the soil moist. Excessive water content in the soil will affect the permeability of the soil, inhibit the respiration of the roots, and be detrimental to rooting. Severely, it will lead to the death of rot. For this reason, on the one hand, we must strictly control the amount of soil watering. For the first time when transplanting, it should be irrigated. Afterwards, depending on the weather conditions, the soil texture, inspection and analysis, and careful watering. At the same time, beware of excessive water droplets entering the root zone when spraying. In the second aspect, it is necessary to prevent tree pool water accumulation. The watering hole left after planting should be filled or slightly higher than the surrounding ground after the first irrigating, to prevent rain or water accumulation when watering. At the same time, in the low-lying and easily reclamated areas, open drains to ensure timely drainage on rainy days. In the third aspect, it is necessary to maintain a suitable groundwater level (general requirements -1.5m or less). At the higher groundwater level, net drainage should be done. When the water level rises in the flood season, deep wells can be dug in the outer part of the root system, and the groundwater can be pumped out of the site with a pump to prevent flooding. 3. Soil aeration: Maintaining good air permeability of the soil is conducive to root germination. To do this, we must do a good job of cultivating loose soil in order to prevent soil compaction. 4. Disease and Insect Pest Control: Insist on prevention. Based on the characteristics of tree species and the law of occurrence and development of pests and diseases, diligently check and do preventive work. In the event of a medical condition, it is necessary to prescribe the right medicine and prevent it in time. 5. Fertilization: After the roots germinate, the roots have low suction fertility, and it is better to use extra-root fertilizers. Usually about half a month, according to the soil pH selected urea, ammonium sulfate, potassium dihydrogen phosphate and other quick-acting fertilizers formulated into a concentration of 0.5% to 1% of the fertilizer solution, spraying in the morning or evening or cloudy days.
