2) Spraying 1:20 fast-living forest antitranspirant on the crown of the tree, covering the whole tree with a sunshade net and cooling by spraying.
3) Before planting, 900ppm of Pingxiukang and 600ppm of Borax metalaxyl are used as mixed bactericides, and the mixture is sprayed on the whole trees containing soil balls.
4) Mixing sulfur powder, mushroom fertilizer, wood chips, yellow loam and peat soil according to the proportion of 1:1: 2.2: 4.6: 6.3, adjusting the pH value of the backfill soil to 5.4, and then mixing 15g of nitrogen fertilizer and biocontrol bacteria (bacillus subtilis).
5) The planting hole is 1-1.2 times of the thickness of the soil ball, the diameter of the planting hole is 1.5-1.6 times of the diameter of the soil ball, and the bottom of the planting hole is of a concave shape. The concave groove is 20cm long, 20cm wide and 15cm deep;
transplanting the dulcamara to the concave planting hole, arranging a water storage tank, filling broken stones in the water storage tank, arranging a polyethylene threaded pipe in the tank, forming a hole on the surface of the polyethylene threaded pipe, and wrapping a layer of non-woven fabric outside the polyethylene threaded pipe; compacting and compacting the backfilled undisturbed soil until the backfilled undisturbed soil is level to the ground, and pouring the fixed root water until the mud surface is wet.
6) After planting, planting the host clover of the canker pathogenic bacteria grass with the width of 0.5-1 m (preventing pathogenic bacteria from infecting the trunk of the Elaeagnus dulcis) along the periphery of the projection edge of the crown as an indication plant. Removing the indicating plants and burning the indicating plants intensively between 12 months and 1 month in the next year, and spraying 800ppm Bor-metalaxyl to the soil for sterilization.
Because the host plant is a herbaceous plant, the plant is more susceptible to diseases than woody Elaeagnus dulcis. When the host plant is infected, the pesticide is sprayed to prevent and control the Chinese dulcamara immediately, the clovers are removed and burnt intensively, and 650ppm of Borax metalaxyl is sprayed to kill bacteria on the soil.
7) And (3) regular maintenance management: after transplanting and fixing, watering times in a maintenance period by taking soil cracks on the surface of a soil ball as watering intervals, and watering 650ppm of naphthylacetic acid rooting water and nutrient solution again one week after planting; after the big tree sprouts new leaves for 35 days, a nitrogen-phosphorus-potassium compound fertilizer with the concentration of 0.4 percent is applied in combination with watering; dissolving urea into water at a ratio of 1:200 30 days after sprouting, and spraying leaves 17-19 days in sunny days; spraying 850ppm of Pingxiukang and 800ppm of Bor and metalaxyl mixed bactericide from 1-2 middle of month and 5-6 middle of month each year, wherein No. 93 gasoline is added into the mixed pesticide according to the volume ratio of 200: 1; and 5-6 months every year, the trunk is wrapped by a double-layer black shading net and a single-layer permeable geotextile so as to reduce the spread of pathogenic bacteria conidia.
As a result: the canker condition of the trees is checked after the trees are transplanted for one year, 57 survivors are transplanted for 60 trees, 3 canker diseases occur due to dry trunks, the holes are formed in the trunks of the Elaeagnus dulcis, and the incidence rate of the canker diseases is 5%.
