As we all know, Hainan Huanghua pear is a precious tree species, if there are conditions, in the vicinity of the residence, in front of the house, behind the house, inside and outside the courtyard, factories, warehouses and other green belts to plant Hainan pear can be both green and value-added, killing two birds with one stone. In the past, most of the pears grew in a harsh natural environment, with a slow growth rate, and often took tens or even hundreds of years to become mature; Due to the progress of science, people's understanding of the growth characteristics of Huanghuali (geographical environment, soil, pH, nutrition, moisture, fertilizer and water, seedling selection, daily management and other factors) has gradually improved, and the artificial planting of Hainan Huanghuali has greatly improved the growth rate of Huanghuali, the speed of becoming a grid, and improved the economic benefits of planting Huanghuali. This chapter is dedicated to introducing the planting characteristics of large, medium and small seedlings of Hainan Huanghuali for your reference.
First, seedlings (nutrient bag seedlings): the biggest advantage of planting this kind of seedlings is that the planting cost is low and the survival rate is high, but its weakness is that the main stem is soft, easy to bend, and the growth is uneven.
Second, the seedling (the main stem has been hardened, the diameter is generally more than 3 cm): this seedling can be planted directly as a greening tree or economic forest, planted with this seedling, the purchase cost is high, the transportation volume is large, but the timber is fast, and the income is fast.
Three, the seedling (tree pole head diameter 1-3 cm): this kind of seedling has three planting methods, one of them is, after digging back the seedling, slightly pruning, direct planting, this method growth rate is slow, the main stem is easy to dry up, the survival rate is low. The second planting method is to plant the seedlings in the nutrient bag first, and then plant after survival, the survival rate of this method is high, but the growth is slow, not convenient for long-distance transportation, and the cost is higher.
The third planting method is the two-preferred low-cut stem planting method, referred to as the preferred cutting rod planting method. The method is: the seedlings are planted in the ground for about two years, and the vigorous seedlings are selected to be planted, which is the preferred seedling.
After digging seedlings, 10-15 cm from the ground, cut off the tree stem, leave the tree head to plant, wait for the new long shoots to grow to about 30 cm, select the most vigorous new branches, as the main stem in the future, leave it to grow, and remove other branches. This is the preferred shoot. This practice is known as the two-pronged low-cut stem planting method.
Advantages of this planting method: convenient for long-distance transportation, high survival rate. The growth rate is fast, and the main stem of the tree is straight and strong.
It is easy to form a lattice (i.e., heartwood) at the junction of the original incision and the new main rod. In short, using this method to plant pears grows fast, has a high yield and is fast.
