Normal flower cutting propagation is usually carried out in sand. Compared with floating board water intercalation method, sandy soil cutting is both troublesome and requires high management. However, the method of inserting water from the floating plate is much more convenient, and the survival rate of the cuttings is high. The rooting rate is more than half months earlier than the sandy soil insertion, and the survival rate of the upper pot transplanting is 100%. Secondly, the probability of getting infected by the floating plate water insertion method is less than that of the sandy soil cutting, and the seedlings are well developed, and the time and effort are saved. First, the use of materials can be used to change the water and convenient tools, such as buckets, glass fish tanks and so on. A foam board smaller than a glass fish tank, with a board thickness of 5 to 8 cm, is first punched into a foam board with a hole spacing of about 3 cm, and then cut along the center point of each row of holes with a knife, so that it is convenient for future removal. Then, the rubber band is fixed on the two ends of the foam board. Second, cutting ear in the mother plant on the selected year of development of robust, disease-free shoots, cut with scissors with a rake, cut to have a slope. Leave 3 to 4 leaves on the top of the cuttings, cut off the rest. If it is a large leaf, cut it in half to reduce nutrient consumption and increase cutting density. Third, the growth period of time plants can be cuttage, but from May to October, the rooting rate is the fastest when the temperature is 18°C ​​to 32°C. 4. Insert the insert into the hole in the foam plate. It is best to let the sun shine on the side of the water container, but shade the net. This is done in order to allow the cuttings to avoid the sun, not to burn the tissue but also to use the sunlight to increase the temperature of the water in the cylinder, which is conducive to hair rooting. To determine the location, add water to the cylinder port. The water is preferably well water. If it is tap water, it should be dried for two days. When the water is added, the foam board floats on the water surface, and the water is changed 5 to 7 days in the spring, and the water is changed one to two days in the summer, after which no management is required. It takes about 10 days to take root, and the maximum root length must be 8 cm after half a month. Generally, 15 to 20 fibrous roots can be grown per shoot and 15 to 20 days. When the basin is up, the board will be lifted, the rubber bands on the two sides will be withdrawn, the board will be opened, the rooting bar will be carefully taken out, and the foam board will still be fixed with rubber bands and can continue to be used. The new strain in the upper pot must be kept in the shade for a week to enter normal maintenance. The varieties suitable for floating plank water insertion are generally woody flowers, such as: Ruixiang, gardenia, privet, hibiscus, Chinese rose, June snow, crape myrtle, jellyfish, boxwood, and fuchsia, but also suitable for some herbaceous flowers. Use this method.
