A new method of original ecological transplanting of wild osmanthus

Abstract

A new method for the original ecological transplanting of wild osmanthus, transplanting trees requires seedling age of more than 2 years and a diameter of 0.4-0.6 cm; before transplanting, draw a circle with the trunk as the center, with a radius of 3 times the diameter at breast height, and draw a circle on the periphery of the circle. Dig a trench with a width of 40cm and a depth of 50-70cm, cut off all the fine roots in the trench, and excavate with soil; before transplanting, dig a planting pit, the size of the pit should be determined by the diameter of the root system, and the depth should be less than Bare or lumpy roots are 10-15cm deep, and the transverse diameter is 30cm larger. The top and bottom of the tree pit should be the same size. A layer of 3-5cm thick nutrient soil should be placed at the bottom of the pit, and the humidity should be 20%; the saplings should face south when transplanting. For planting, the pit is filled with sandy loess, the ratio of loess to sand is 3:2, the temperature during transplanting is between 15-25 °C, and after transplanting, water is poured first, keep it moist for a week, and water evaporation is maintained at 20%; The ditch should be planted at a distance of 1 meter to ensure sufficient sunlight, moist soil and water, and regular manual weeding. When weeding, remove the excess branches and buds below, so as to keep nutrients from being wasted and improve the survival rate.

Description

technical field [0001] The invention relates to the technical field of arboriculture, in particular to a new method for original ecological transplanting of wild osmanthus fragrans. Background technique [0002] Osmanthus fragrans is adapted to the subtropical climate area, and it is warm and humid in nature. The average temperature in the planting area is 14-28°C, the average temperature in July is 24-28°C, the average temperature in January is above 0°C, the lowest temperature it can withstand is -13°C, and the optimum growth temperature is 15-28°C. Humidity is extremely important to the growth and development of sweet-scented osmanthus. The annual average humidity is 75%-85%, and the annual precipitation is about 1000 mm. Especially when young and adult trees bloom, they need more water. If they encounter drought, flowering will be affected. Strong sunshine And shade is not good for its growth, generally requires 6-8 hours of light per day. [0003] Osmanthus fragrans l...
