Breeding method of multihead
When gardening enthusiasts first come into contact with the cultivation of multihead chrysanthemum, the most confused thing is how to improve the success rate of cuttage and grasp the timing of sowing. These blooming Compositae plants actually contain unique cultivation codes. Master a few key skills and turn your balcony into a chrysanthemum garden. Analysis of the whole process of cuttage propagation. Soilless substrate is the key to the success or failure of cuttage. A 3:1 ratio of chaff and perlite is recommended. This structure not only ensures breathability, but also maintains moderate humidity. Special attention should be paid to the need to be leveled and compacted in advance to avoid later collapse and affecting rooting. If there is a temporary shortage of material, coconut bran can be used instead of rice bran, but it needs to be soaked in clear water to desalinate. The prime time window controls the plum rainy season from May to June, which is the ideal cuttage period, when the air humidity reaches 70%-85%. It is recommended to combine the weather forecast and choose to operate three days before continuous rainy weather. In dry areas in the north, a microclimate can be created by covering transparent arches. Experience shows that operating when the morning dew is dry can increase the survival rate by 15%. The three major criteria for selecting branches of mother plants should select semi-lignified branches, and the diameter should be controlled at 2-3 mm. Pay attention to the bud points at the leaf axils, and cuttings with 3-4 full bud points are more vibrant. Put it into a crisper immediately after picking, and pad with moist moss to maintain freshness for 4 hours. Never use flowering branches, which have consumed a lot of nutrients. Scientific cuttage operation specifications use a 45-degree oblique angle to treat the base to increase the water absorption area. The insertion depth is strictly controlled at 1/3. If it is too deep, it is easy to rot. While maintaining the row spacing of 3cm, it is recommended to arrange it in a triangular pattern to ensure that each plant receives even light. It is recommended to use 800 times carbendazim solution for the first time to effectively prevent fungal infection. Advanced skills for sowing and seedling raising
2-4 Monthly sowing should follow the principle of "watching the sky and acting": the Yangtze River Basin should be suitable before and after the sting, and the north should be suitable before and after the Qingming Festival. When sowing with plug trays, place 2-3 seeds in each hole, and the soil thickness shall not exceed 0.5 cm. Maintaining a temperature difference environment of 18℃ per day and 10℃ at night can significantly improve the uniformity of germination. The core point of pot maintenance is when the new fibrous roots are milky white and 2 cm long, the best time to pot. Select a root control basin with a diameter of 10cm, and lay ceramite on the bottom layer to enhance drainage. It is recommended to use a mixed substrate with peat soil: vermiculite =2:1, fill the soil into 2/3 of the basin for the first time, and gradually add soil as the plant grows later.
It takes 120 days of careful care from cuttage to blooming, and each stage has its own special needs. It is recommended to establish a maintenance log to record changes in temperature and humidity and plant responses. When autumn becomes stronger, you will surely be able to harvest clusters of gorgeous chrysanthemum shadows.
