Example Embodiment
[0034]Example 1
[0035](1) Choose sandy loam flat land, or slope land with a slope of less than 15°, close to the water source, and freely drained land as the nursery. The planting density of mother plants is: row spacing 2m, plant spacing 1m;
[0036](2) After planting the mother plant, before freezing in November of the first year, stubble close to the ground to promote the germination of branches;
[0037](3) Apply 25kg / mu of high-nitrogen compound fertilizer from April to May;
[0038](4) From the end of May to the beginning of June, remove the weak and over-densified sprouts, keep the strong sprouts, and the horizontal spacing of sprouts is greater than 3cm;
[0039](5) Spray 300 times potassium dihydrogen phosphate water-soluble fertilizer 5 days before layering;
[0040](6) Remove the leaves within 15cm of the sprouting strip from the ground before tying and overflowing;
[0041](7) Select No. 24 iron wire with a diameter of 0.50mm as the binding material, and bind it at a distance of 1cm from t...
