How to water transplanted crabapple in spring
The transplanting of spring crabapple is related to the growth of the whole year, and scientific watering is the key to survival. As a famous traditional flower in China, the root system of crabapple is extremely sensitive to changes in water. Mastering water management skills after transplanting can not only promote the development of new roots, but also prevent the risk of death from rotten roots. From practical watering to environmental control, this article analyzes the complete maintenance plan for transplanting crabapple. Spring crabapple transplanting and watering skills 1. The correct way to water thoroughly requires the dipping basin method or slow watering method for the first time: Put the flower pot into the basin and soak it for 15 minutes, or use a fine-spout pot to slowly circle the edge of the basin. When the drainage hole on the bottom of the basin continues to seep water for about 30 seconds, the penetration standard will be reached. Avoid flooding and irrigation with large water to cause soil hardening. It is recommended to irrigate twice at an interval of 10 minutes. 2. Control the watering frequency to keep the soil moist for the first three days after transplanting, and implement the principle of "seeing dry, seeing wet" from the fourth day. Insert 2/3 of the soil with a bamboo stick and replenish water when pulling out no clay. It is recommended to pour water every 5 - 7 days in the northern region, and extend it to a 10-day interval in the humid southern region. 3. Common watering misunderstandings: foliar spraying water can easily cause black spot disease, which should be avoided when newly transplanted plants. The water temperature needs to be close to room temperature, and the temperature difference exceeding 5 ℃ will stimulate the root system. Stop watering on rainy days, and use tray water supply method when the air humidity exceeds 80%. Five major precautions for transplanting crabapple 1. Root protection specifications Keep 1/3 of the original soil to protect the roots, prune the broken roots and soak them in carbendazim solution (1: 800) for 30 minutes. Apply healing agent to the main root with a diameter of 0.5 cm, and retain white new root tips. 2. The recommended ratio of new soil for soil disinfection treatment is 5:3:2. Old soil must be disinfected at high temperature: put it into a sealed bag and heated in the microwave for 3 minutes, or spread it out for 3 days and then mix with Bacillus subtilis. 3. Environmental control key points need to be shaded and maintained for 15 days after transplanting, and a 50% sunshade net is used. Keep the temperature at 18 - 25 ℃ during the day and no lower than 12 ℃ at night. Rotate the flowerpot regularly to ensure uniform light reception and avoid off-crown growth.
Through scientific watering and careful maintenance, the survival rate of crabapple transplanted can reach more than 95%. It is recommended to combine phosphorus and potassium fertilizers to promote root development, and add seaweed fertilizer every month during the growth period. Immediately check the soil moisture when you find that the leaves are wilting, and adjust the maintenance plan in time to let your crabapple bloom brightly every year.
