Many people say that the survival rate of rubber tree propagation by cutting is not high, but the experimental results of flower friends show that it is not difficult to improve the survival rate as long as we master the technical essentials. Let's share the cutting method of this flower friend:
First, the cutting time is high in summer, and the air humidity is relatively high. Generally, the end of June to the end of July is the best time for cuttings to survive. 2、 The selection of cuttings has a direct impact on the survival rate of cuttings. Therefore, the cuttings to be cutted should be strictly selected. Generally, the next year's thick branches with the surface completely lignified should be selected
Make cuttings. This kind of branch has more sufficient nutrients, so it is easy to take root and has strong disease resistance. On the contrary, if the ten lignified branches are selected, they are not easy to root and survive, while the tender ones are easy to rot. 3、 Preparation before cutting: one alcohol lamp (or one cup of boiling water), several sterilized jars (boiled with water), one cutting bed, which can be replaced by wooden box (the length of the wooden box depends on the number of spikes, and the depth is 15 cm). The bottom of the wooden box is evenly made into small holes with a carpenter's drill, so as to be permeable. 5 cm thick coarse river sand (washed with water) is laid on the top of the coarse sand The fine river sand with a thickness of l0 cm (also need to be washed with water) is poured with a watering can and covered with plastic cloth, iron wire or wooden square. Its height is 35-40 cm, and its length is slightly longer than the wooden box used for cutting bed. 4、 Cutting operation method 1. Quickly cut the selected strong branches into 12-15 cm sections and burn them on the alcohol lamp (or scald them in boiling water). Burning (scalding) time: the white sap of rubber tree does not continue to overflow into degrees (Note: This is the key to the survival of cuttings. There are two purposes of burning or scalding the cuttings. One is that after burning or scalding the cuttings, the SAP can not continue The second is to prevent the bacteria in the sand or air of the cuttage bed from infecting the wound and causing rot)
2. Remove the extra leaves and leave only two.
3. Put it into a can bottle, fill it with clear water (the water should be dried 2-3 days in advance) and put it in a sunny place. Clean the water to the leaf dough 2-3 times a day, reduce the temperature, and change the bottle water once every 2-4 days.
4. When the temperature is high and the sun is abundant, the white roots can be produced in 8-10 days.
5. When the root is 3-5mm long, it can be implanted into a wooden box filled with river sand, with a depth of 7-9cm, and it should be inserted directly. After spraying enough water, cover the plastic cover and spray clean water once a day in the morning and evening.
6. After 10-15 days, the cuttings can be transplanted into the flowerpot of plain soil and placed in the shade. After half a month, the roots can be fixed, the extra axillary buds can be pieced out and two can be left, and the thin fertilizer and water can be poured, and gradually moved from the shade to the full light.
