At this time, there are 6 cm thick crape myrtle branches that can be inserted alive. Do you want to put it in the greenhouse to make bonsai? There are new branches on the old branches. Can you put them together? I don't think so. First, the time is wrong. Second, there is no precedent for whole stem cutting. Why not use a stump?

Now it should be stored in the sand, and the cuttings should be taken out from late March to early April. Softwood cuttings are mostly in the first half of June in summer, and they are inserted as soon as they are picked.

Hard branch cutting technology of Lagerstroemia indica

1. Cutting and storing sand. 165438+1In the middle of October, cut off the annual robust branches without plant diseases and insect pests from Lagerstroemia indica, and bind the whole branches into small bundles according to specifications (cut them short again when cutting). Dig a ditch with a depth of 80- 100 cm in an outdoor leeward place with good drainage, lay a layer of wet sand at the bottom of the ditch, and bury the bundled branches and wet sand in the ditch in layers.

Second, prepare the soil for the bed. Lagerstroemia speciosa likes sunny, warm and humid environment, is drought-resistant and afraid of waterlogging, has lax requirements on soil and strong adaptability, and grows best in well-drained, fertile and slightly calcareous soil. After the nursery land is selected according to the above conditions, the selected nursery land will be ploughed once in the autumn or early spring of the following year, and 500-800 kilograms of farm manure, 50 kilograms of calcium superphosphate and 20 kilograms of compound fertilizer will be applied per mu, and then the bed will be made. The bed is 20 cm from the ground, the width of the bed surface is 1.2m, and the length of the bed will vary with different sites, and there will be traces 40-50 cm wide between beds. The soil must be disinfected/0/5 days before cutting, and 2-3% ferrous sulfate solution or 40% carbendazim 800 times solution should be sprayed on the bed surface. After the soil is fully wetted, cover it with plastic film, uncover the film after 1 week, and then carry out cutting in 2-3 days.

Third, cutting. At the beginning of April, the branches from the sand storage were taken out, cut into cuttings with a length of 12- 15 cm, soaked in 200× 10-6 NAA solution for 20 hours, and then inserted into the seedbed. The burial depth is 2/3 of the cutting length, the row spacing between plants is 10 cm× 15 cm, and the bed surface is slightly covered with a layer of straw. In the future, water the nursery in time according to the degree of dryness and wetness, and always keep the nursery in a semi-humid state, and it will take root and sprout in about 1 month.

Satisfied, hope to adopt.
