Transplanting Sapium sebiferum on both sides of the road to improve the survival rate
Sapium sebiferum has strong adaptability to soil. It can grow in red soil, yellow soil, yellow brown soil, purple soil, brown soil, soil with different texture from sand to clay, and acidic, neutral or slightly alkaline soil. Sapium sebiferum is one of the tree species with strong salt resistance. Bird tallow requires high soil moisture and can withstand short-term stagnant water. At the same time, it has a certain degree of wind resistance and ruffled land is more resistant to dry, early and barren. In addition, Sapium sebiferum has strong resistance to toxic hydrogen fluoride gas. Because Sapium sebiferum likes to be moist and fertile, however, when Sapium sebiferum is used as a greening tree species, it is generally planted on both sides of the road, the soil wetness is low, the consolidation is more serious, and the soil is generally not fertile. When planting on both sides of the road, the survival rate is not high, and it needs to be watered frequently after planting, usually once every 10 years, so a lot of water resources will be wasted. And the labor cost of planting and so on.
Select a 4-year-old nursery with a height of 1m and a diameter of 6cm. The transplanting of Sapium sebiferum can be carried out in March and can be planted both before and after germination. When transplanting, you must bring soil balls, 40cm in diameter, dig a large pond of 1m × 1m × 1m, apply rotten organic fertilizer to the bottom of the pond, backfill the soil, and then put it into the seedlings. The planting depth should be controlled at the top of the overlying soil 8cm from the roots of the seedlings, and then irrigated once more, watered again three days later, and watered again in the next 20 days. After excavating the soil ball, the water-retaining agent was spread into the soil ball and irrigated with water, and the water-retaining agent was carboxymethyl cellulose potassium 0.2kg. The earth ball is dug into a top shape instead of a plate or cone, and the soil ball is fastened with a straw rope. Pruning and picking leaves should trim the inner bore branches, overlapping branches and disease and insect branches, and strive to keep the tree shape intact. A supporting wood should be set up to fix the trunk after planting.
