Poplar is one of the fastest-growing green plants besides eucalyptus. Its speedy nature is extremely prominent in the seedling stage. The relative height of annual poplar seedlings is generally 3.5 meters long. , the tree diameter can reach about 3.5 cm. According to the national afforestation seedling specifications, the ground diameter of first-class poplar saplings should exceed 3.5 cm, and the seedlings are taller and greater than 3.5 meters. The ground diameter of second-class poplar saplings exceeds 3 cm, and the seedlings are The height is more than 3 meters. To cultivate standard models of high-quality first-level greening seedlings, only 2,000-3,000 cuttings can be produced per acre, while second-level seedlings can be cultivated to produce 3,000-4,000 cuttings. However, in terms of specific production, many farmers increase the density of cuttings, with 5,000-6,000 cuttings per acre, or even more. In fact, this is not recommended. The seeding land should be sand or light soil that is rich, flat, easy to water, and has good drainage.

The better pre-seedling land is deep plowing in the autumn of the first year. Precision sowing, fertilizer application and soil disinfectant are carried out the following spring. In order to avoid the occurrence of underground diseases and insect pests, poisonous grains or thiamine granules can be used. On harrowed agricultural land, the bed should be made with a trench level bed. The bed is 1.5 meters wide and 5 meters long. The trench in the middle is 20cm deep and 30cm wide. In order to ensure that the seedlings are flat, the surface of the seedlings must be polished several times. Bottom water is important to ensure the quality of seed germination. Watering should be carried out twice before planting. After the first watering, the bed should be leveled. After the second watering, when all the water has seeped down, the seeds can be planted. bed surface. When planting, choose a windless day, spread the seeds evenly on the bed, and then mix them with fine sand and retting fertilizer to make the seeds covered thinly and have the privacy of seeds.

Based on the work experience of raising seedlings, cut the branches into 12 to 14 cm seedlings and soak them in acetic acid or rooting agent solution for thirty minutes. It is most suitable to plant between 10,000 and 15,000 per acre. You can also apply farmyard manure and then spread black mulch to kill weeds and stabilize the soil. Just peel off the mulch film first to prevent the plug from being suffocated by the mulch film! Agricultural mulch film creasing machine is placed on the ground. After inserting, sprinkle some fine soil and tamp it down. When watering, add insecticides such as chlorpyrifos to prevent underground pests from eating their roots. When the branches are ten meters long, remove the tillers and leave a strong and strong branch. Pay attention to insert 3 rows on the 75cm ground mold, with a spacing of 15cm between plants. Poplar has a wide range of uses, rapid growth and development, and is easy to plant.

Similarly, it can take 5 years to become a professional. Wood is often used to make customized furniture. It is used in large quantities and is cheap. Let me tell you about the planting technology of poplar trees. Sowing time: Poplar seeds are planted in spring. They have the characteristics of fast budding and easy breeding, but their growth and development are relatively slow. This method is generally not used. Cuttings and root seedlings are commonly used, generally April and June are more suitable. Poplar saplings can be cut after the soil freezes in spring. Choose rich, moist soil with good drainage for plowing. The cuttings are about 15 centimeters long, and there should be a bud 1cm from the top. The cuttings should be soaked for 24 hours. Inject water immediately after inserting directly into the seedling stage. After the germination stage, do a good job in watering, wiping buds, fertilizing and other management methods.
