Populus euphratica

Using Yiyang roots to cut and dry afforestation can significantly reduce the cost of seedling raising, transportation, digging, and planting, reduce labor intensity, increase the survival rate of afforestation, and accelerate fast-growing and high-yielding forest trees. When operating, you should grasp the following technical aspects. 1. Cut roots from the poplar nursery to intercept the seedlings used for afforestation, should sooner rather than later, the earliest in the Italian poplar to stop growing a large number of leaves. Don't leave the pile too high, and the section should be smooth and smooth to prevent the base of the seedling from cracking and tearing the bark. 2. Select the seedlings and cut roots and choose dry I-grade seedlings with a height of 4.5 meters or more and a diameter of 3.5 centimeters or more, and no pests and damages to be used for afforestation. If the seedlings are insufficient, they can be supplemented with Grade II seedlings with a height of 3.5 meters or more and a ground diameter of 3 cm or more. 3. Pruning and selecting seedlings will promptly remove all side branches. In the event of poor lignification and a lack of fine tipping, it should be cut off and cut at a depth of 2 to 3 cm above the top of the stout bud. 4. Grading The seedlings after pruning are graded by a difference of 0.5m. After grading, in order to ensure that planting dry depth in place, should be marked with red paint on the site in a timely manner designated parts. Then according to 20 or 30 standard, the quota is tied. 5. Soak all the bales and seedlings in the nearest place and use the rivers and lakes to soak the water. The depth of the base water shall account for 1/2 of the total dry height, and shall not be less than 1 meter at least. Soaking the shortest to ensure 3 days, up to 2 months no problem. Seedlings are easy to float into the water and can be used to suppress the seedling stem base with heavy objects such as cross-wood blocks. 6. The reforestation land is preferred for lands with a groundwater table of 1.5-3 meters, sandy land and light sandy soil, followed by sandy soil, and once again a medium-sized earth and light clay. Depths in the groundwater table, especially in the soil, and in places where the soil is thin and compacted, must not be planted with poplars. 7. The hole-drying and afforestation time is generally from early February to early March. It is now advocating autumn fall in November to have better results. Before the hole is punched, it should be accurately measured along the line spacing and marked with small wooden poles or boring bars or small bamboo poles at the setting point. The row spacing is determined according to the cultivation target: the cultivation of short-cycle industrial raw material forest (such as fiber sheet) is generally 22 meters or 23 meters, and cultivated agricultural building forest, generally 44 meters. Punching tools generally use a diameter of 4 - 5 cm, 1.2 meters long steel fiber, with wood or iron hammer head according to the planting point vertical hole to seedlings planting depth, generally 60-80 cm, large seedlings deep 1 meter. 8. Before the grouting is done, the holes must be filled with thin slurry. In the case of sandy soil and light sandy loam, direct irrigation of water can also be used. If it is a relatively dry sand or quicksand, after the irrigation grouting, it can easily cause the sand to plug the hole. It should be inserted into the hole to make it dry. After inserting, pouring enough water to promote rooting. 9. Insert the seedlings into the dry hole and insert the seedlings in a timely manner until the red paint is marked and the ground level. The seedlings are gently shaken for several times to loosen the soil and connect the seedlings. After the stem is dry, it is almost shoveled and sealed. After the strengthening of tending management, until the forest becomes.
