Preparation before cuttings
According to the local climate and other factors, it is generally better to collect it before the buds on the Hongrui wooden branches, that is, from late March to early April.
After picking, you need to cut it immediately. 3 buds need to be kept on each cuttings. The upper end is cut at 15-20 mm from the upper buds, and the lower end is cut into a Maltal shape at 3-5 mm. The length of each cutting cut is between 8-12 cm. It is best to choose about 5-10 mm in the bottom diameter of the cuttings, which can ensure a good root rate.
The cut strip is tied up in accordance with 50 bundles, and it is placed in a flat container with 5-6 cm deep water for hydrolysis. It takes 3 days and nights. For conditions, you can drain the water while irrigation. If there is no condition, you can change the water once every morning and evening. Then put the hydrolyzed cuttings into the container, and then pour the ABT1: 500000 solution inward, and the depth is about 3-5 cm. The soaking time depends on the temperature of the water. When the water temperature is below 8 ° C, it needs to be soaked for about 6-8 hours. When the water temperature is above 8 ° C, it needs to be soaked for 3-4 hours.
Choose a flat ground with shade, spread about 6-8 cm thick wet sand, and invert the cuttings at a sedimentary angle of 75 degrees. Cover a layer of wet sand with a thickness of about 5-6 cm. And watering 2-3 times a day, pay attention to the need to use sun exposure. After about 20-30 days, you can take it out for cuttings.
