How to Plant Golden Bullet Tree in Summer
The unique climate of high temperature and humidity in summer brings both opportunities and challenges to the planting of Golden Bullet Tree. Mastering scientific planting methods can not only improve the survival rate of the stakes but also lay a solid foundation for later shaping. This article systematically analyzes the four core links of planting Golden Bullet Tree in summer, helping you cultivate healthy plants easily.
Complete Process Analysis of Planting Golden Bullet Tree in Summer
Potting Soil Mixture and Substrate Treatment
High-quality potting soil is the first step to success. It is recommended to use a mixed substrate of decomposed leaf soil + coarse river sand + vermiculite (proportion 2:1:1), which can ensure good drainage and provide necessary nutrients. For heavy clay soil, add 30% perlite to improve it and prevent waterlogging and root rot. Soak the substrate with boiling water before planting, let it cool naturally, and use it to effectively kill eggs.
Root Pruning and Wound Treatment
Retain the main roots to a length of 15-20 cm and keep 3-5 healthy lateral roots. Cut the ends diagonally with scissors disinfected with alcohol to increase the water absorption area. Keep 3-5 buds on the branches, with the cut 0.5 cm away from the buds. After treatment, immediately apply a mixture of erythromycin ointment and carbendazim paste (proportion 1:3) to the roots to form a double protective layer.
Key Steps for Disinfection and Root Promotion
Prepare a 0.1% potassium permanganate solution to soak the roots for 20 minutes for thorough disinfection, then switch to a 500ppm naphthalene acetic acid solution to soak the roots for 2 hours. This method is 40% more effective than using carbendazim alone and, combined with perlite substrate, can promote the rapid formation of callus.
Scientific Planting and Moisture Management
Use the deep burial and shallow exposure method: the soil depth should reach 2/3 of the stake, leaving only the top buds exposed. After planting, cover with double-layer plastic bags (inner layer transparent, outer layer black) and uncover for ventilation for 30 minutes before 10:00 every day. Maintain the substrate moisture at 60%-70% (it should clump when held in hand and scatter when dropped), and new buds will appear after 20 days.
By precisely controlling soil mixture, standardizing root treatment, strengthening the disinfection process, and optimizing moisture retention, the success rate of planting Golden Bullet Tree in summer can be significantly improved. It is recommended to perform operations during continuous rainy and overcast periods, using a 75% shade net, which can achieve a survival rate of over 90%. After 45 days of planting, apply a dilute soybean cake solution to promote root development.
