Embodiment 1

[0017] 1. Select an excellent single plant with a tree age of about 6 years, no paulownia arbuscules, disease hazards, fast growth, and strong disease resistance as the mother tree. Take the young shoots of the year as cuttings in the middle and upper part of the mother tree, and the time for picking. For April, select healthy, disease-free semi-lignified branches;

[0018] 2. The cutting branches are 15cm long and contain 2 full axillary buds. The incision of the base of the ear is obliquely cut, and the base of the ear is dipped in 1‰ potassium permanganate solution for 30 seconds, and then soaked in ABT1 No. rooting powder or ABT1 in a bundle of 20 plants. 1h in the solution of GGR50ppm;

[0019] 3. Make a low bed with a width of 120 cm, and use plastic cloth to make a nutrient bowl with a height of 20 cm and a diameter of 30 cm, and place it in the low bed. Disinfect to prevent underground pests from harming seedlings;

[0020] 4. Compaction after cutting, the cutting de...

Embodiment 2

[0024] 1. Select an excellent single plant with a tree age of about 6 years, no paulownia arbuscules, disease hazards, fast growth, and strong disease resistance as the mother tree. Take the young shoots of the year as cuttings in the middle and upper part of the mother tree, and the time for picking. For April, select healthy, disease-free semi-lignified branches;

[0025] 2. The cutting branches are 20cm long and contain 3 full axillary buds. The incision of the base of the ear is obliquely cut, and the base of the ear is quickly dipped in 1‰ potassium permanganate solution for 30 seconds. Powder or GGR5Oppm solution for 2h;

[0026] 3. Make a low bed with a width of 120 cm, and use plastic cloth to make a nutrient bowl with a height of 20 cm and a diameter of 30 cm, and place it in the low bed. Disinfect to prevent underground pests from harming seedlings;

[0027] 4. Compaction after cutting, the cutting depth is controlled at 8cm, and the cutting density is 3cm×4cm; man...

Abstract

The invention discloses a method for cutting propagation of paulownia relates to a planting method of paulownia and belongs to the field of agricultural planting. The method for cutting propagation of paulownia is characterized in that: cutting propagation is conducted by choosing ripe branches, suitable plant growth regulator and the concentration and handling time of the plant growth regulator to promote fast root growth of cuttings and effectively increase the rooting rate, the rooting amount and the rooting quality. The method for cutting propagation of paulownia has the advantages of simplicity, practicability, low cost and short period can achieve quick and effective vegetative propagation of paulownia; and the method for cutting propagation of paulownia plays a significant role in accelerating the excellent clone generalization of paulownia and promoting the construction of the bioadisel oil raw material forest.

Description

[0001] technical field [0002] The invention relates to a cultivation method of paulownia, which belongs to the field of agricultural planting, in particular to a method for propagating paulownia by cuttings. Background technique [0003] Paulownia is one of the most important fast-growing high-quality timber tree species and ecological protection tree species in my country. It has always played an irreplaceable role in the construction of commercial forests and ecological environment protection in my country. my country is also the country with the richest germplasm resources and the widest distribution range of paulownia in the world. In the mainland alone, there are nine species with two varieties and many variant types. Paulownia wood is light, easy to process, bright and beautiful texture, not easy to warp and deform, not easy to burn, good insulation and sound-conducting performance, and also has the advantages of moisture insulation, corrosion resistance, and easy d...
