Selecting suitable cutting materials, processing cutting materials, preparing cutting substrates for cutting operations, management of desert military pillars after cutting, scientific name Salix psammophila, is a drought-tolerant and salt-alkali tree species widely distributed in the desert areas of northern my country. Due to its developed root systems, it can stabilize sand and prevent wind, and is known as the "Desert Guardian". In the arid desert environment, how to efficiently cultivate desert military pillar seedlings has become a concern for many horticulturists and greening engineers. This article will introduce in detail the cuttage methods of desert military pillars and help everyone master the skills of cultivating high-quality seedlings in arid environments. Choose suitable cuttage materials 1. Select healthy willow branches, generally choose branches with a diameter of 1-2 cm and a length of between 20-30 cm.
2. The best time to collect branches is in spring or autumn, when the branches grow vigorously and have high water content, which is conducive to the survival of cuttage. Processing cuttage materials 1. Trim the collected branches to remove the weak and withered parts.
2. Treating the bottom of the branches with rooting powder can improve the survival rate of cuttage. Soak the branches in the rooting powder solution for a soaking time of generally 30 minutes. Prepare cuttage substrates 1. Choose substrates with good air permeability and strong water retention capabilities, such as river sand, perlite, etc.
2. Stir the substrate evenly and maintain a certain humidity for ease of cuttage. Carry out cuttage operation 1. Insert the treated branches into the substrate to a depth of about 1/3 of the branch length.
2. Keep the branches upright when inserting and avoid tilting or inserting them upside down.
3. Insert one plant at a certain distance and maintain a certain spacing to facilitate ventilation and light transmission. Management after cuttage 1. Watering: Water in time after cuttage to keep the substrate moist, but pay attention to avoid standing water to avoid branch rot.
2. Fertilization: About one month after cuttage, appropriate amounts of nitrogen fertilizer can be applied to promote branch growth.
3. Trim: Trim weak and withered branches in time to keep the plants neat.
4. Prevention of pests and diseases: Regularly inspect cuttage seedlings and prevent and control pests and diseases found in a timely manner.
Although the cutting method of desert military pillars is relatively simple, it is still necessary to pay attention to details in actual operation. Only by mastering the correct cutting method and combining scientific maintenance and management can high-quality desert military pillar seedlings be cultivated in arid environments. According to "China Greening" The "Desert Greening Technical Guide" released by the magazine shows that the survival rate of desert military pillars can reach more than 80%, providing strong support for the greening cause in desert areas in northern my country.
