Problems solved by technology

[0004] The present invention aims to provide a method for improving the rooting and survival of Liriodendron tulipifera cuttings. The method is used to raise seedlings by cuttings. One is to overcome the problem of sprouting first and then growing roots when cutting hard branches of Liriodendron tulipifera; It effectively solves the problem that the cuttings of Liriodendron chinensis are easy to rot and cause difficult rooting and new roots are easy to necrosis, and improves the rooting survival rate of hardwood cuttings of Liriodendron chinensis, increasing the seedling rate from less than 30% to 90%.

Embodiment 1

[0027] 1. Cut cuttings: On the 2-year-old tulip tree, choose 0.5 thick branches with high degree of lignification, no pests and diseases, and strong growth. Each cutting retains 2-3 lateral buds, cut to 15cm in length, and cut the upper end to cut the buds. Cut flat at 1cm, cut the lower end into a 45-degree bevel, and loosen each 10 pieces.

[0028] 2. Disinfection and sterilization of cuttings: 700 times solution of Genfuling, soak the lower end of the cut cuttings in the medicinal solution for 30 minutes, then soak the cuttings with rooting liquid for 2 hours to take out the cuttings, and coat the cuts at the lower end with fresh straw ash.

[0029] 3. Cutting the cuttings to invert the roots: dig a trench in the sun, 30cm wide, 23cm deep, and the length depends on the number of cuttings. Paving 5 cm thick sand at the bottom of the trench is conducive to water seepage. After leveling, place the cuttings upside down. Place it evenly, fill the gaps with coarse sand, and then cover...

Embodiment 2

[0039] 1. Cut cuttings: On a 3-year-old tulip tree, choose 0.8cm thick branches with high degree of lignification, no disease and insect pests, and strong growth. Each cutting retains 2-3 lateral buds, cut to 15cm in length, and cut the upper end. Cut the buds 1cm flat, cut the lower end into a 45-degree slope, and loosen each of the 10 buds.

[0040] 2. Disinfection and sterilization of cuttings: 800 times solution of Genfuling, soak the lower end of the cut cuttings in the medicinal solution for 30 minutes, then soak the cuttings with rooting liquid for 2 hours to take out the cuttings, and coat the cuts at the lower end with fresh straw ash.

[0041] 3. Inverted cutting roots: dig a trench in the sun, 30 cm wide and 23 cm deep. The length depends on the number of cuttings. Paving 5 cm thick sand at the bottom of the trench is conducive to water seepage. After leveling, place the cuttings upside down. The top should be placed flat, fill the gaps with coarse sand, and then cover t...
