What tree is Fatong?

Fatong (Platanus acerifolia): Deciduous tree of Platanus, with bell-shaped crown and palm-sized leaves, 3-5-lobed. Flowering in March-April, monoecious, aggregate fruit spherical, and fruit ripening in June 6- 10/0. Positive fast-growing tree species, with strong stress resistance and a little cold tolerance, are easily blown down by strong winds because of poor root development. The requirements for soil are not strict, and it can resume growth after short-term flooding, with strong germination and pruning resistance. Sowing and cutting can be done.

Folding cuttage propagation

Collect chips

Cutting cuttings should be harvested in late autumn and early winter, and 1 annual shoots sprouted from seedling trunk or robust mother trunk are preferred, and 1 annual shoots sprouted from crown can also be used. In order to ensure the supply of cuttings, a cutting nursery with seedlings can also be established.

Cutting and machining of drill cuttings

Immediately after the cuttings are harvested, they are cut into cuttings with a length of 1.5 ~ 20 cm, and each cutting leaves two nodes and three complete buds, because there are more nutrients in the branches than in the nodes. The lower incision should be close to the node, generally about 1cm away from the bud base, which is beneficial to healing and rooting, and the upper incision should be 0.5~ 1cm away from the bud tip to prevent the terminal bud from wilting due to dehydration. Every 50~ 100 cuttings are bundled into 1 bundle, and then a pit with a depth of 60 ~ 80 cm and a width of 80 cm is dug in the leeward with good drainage, and the pit length is determined by the number of cuttings. The bottom of the pit is paved with a layer of virtual soil, and the cuttings stand upright on the virtual soil with their heads down. Finally, cover the soil in a spherical shape to prevent rainwater from penetrating, and take them out for cutting in the next spring. Spring can also be harvested and transplanted, and the survival rate is also high.

Cutting propagation method

Before cutting, you should choose a well-drained, loose and fertile plot, and make it into a cutting bed after deep turning, disinfection and leveling. In the first half of March, the cuttage bed was irrigated 1 time, and the whole bed was covered with plastic film after seepage. At this time, the cuttings stored in the sand are taken out, soaked in rooting agent 1000 times solution for 2~3 days, and the rooting agent 1 time is changed every 24 hours. After the ear dipping is completed, the cuttings are carried out according to the plant spacing of 15cm×30cm. Before cutting, drill holes with a hard stick with the same thickness as the cutting, with a depth of about 10cm, and then carry out cutting, with the cutting exposed to the ground for about 5cm. After the whole bed is inserted, the cuttings are sealed with fine soil to make the cuttings closely contact with the soil.
