In the season when trees are planted in the spring, Dongling Township, Zunhua City, will plant large numbers of fruit trees. Some of them are supplementary plants, some are better or worse, and others are the expansion of orchards. In order to help fruit growers to plant good seedlings, the fruit tree planting technology is briefly described as follows:
One must choose a good seedling
First of all, we must select the species and species. To select tree species, varieties, or specialty tree species suitable for local planting. Second, we must choose the quality of seedlings. The first grade seedlings and special grade seedlings were selected. Characteristics: Strong root systems, thick main roots, many roots, no pests, no root-canker disease, root hairy disease, apple aphid, etc.; plants are robust, trunk roughness is 0.8-1 cm or more, dry height 1 Above meters, there are 5-7 buds full of stems, no pest damage; the selected tree is pure, the type of rootstock is correct, and the grafted interface heals well; the seedlings must grow uniformly and have the same size.
The second is to plant a good tree
To plant a tree, you must grasp the following points:
1. Improve the soil. To establish a high-standard garden, it is necessary to first determine whether the orchard soil is suitable for the growth of fruit trees before planting. Otherwise, soil improvement is required. Generally, the soil suitable for fruit tree growth is neutral sandy loam soil, and the partial or partial slime of the soil is not conducive to the growth of the fruit tree. It can be used to deepen and expand the hole (1 cubic meter for the hole) before the planting, and the clay or clay mixed with sand can be used for soil improvement. Foot organic fertilizer, or grass and straw fertilizer.
2. Fruit tree colonization. If there is no fruit tree management experience, planting density should not be too dense, should be more than 3 meters and 4 meters; if there is fruit management experience, can be appropriate dense planting, such as peach trunk shape can be 1 meters 2 meters, 1.5 meters 2.5 meters.
3. Configure the pollination tree. Pollination trees should be planted at intervals of 3-4 rows, or at intervals of 7-8 plants. Special emphasis: Large cherry and plums require high densities for pollination trees, and should be numbered for more than 3-4 species, one for each line.
4. Select the appropriate tree planting time. Before and after the Ching Ming Festival, the buds will be planted when they are about to sprout.
5. Seedlings before planting. If the number of seedlings is larger, they should be graded and placed in a cool and sheltered place. Pre-plant treatment: (1) water immersion. Soaking in fresh water for 24 hours before planting can increase the survival rate. (2) Colonization according to the size of the classification when planting, so that the grown tree is the same size and easy to manage. (3) Perform root and graft interface processing. It is necessary to cut off the dryness of the roots of the pests and the joints at the joints, remove the interface film, and disinfect the pests and fungi with insecticides. When planting the root group properly trimmed, cut off part of the fibrous roots and roots before planting, so as to expose white, can promote multiple roots, hair roots.
6. Planting trees. Digging pits, planting trees in shallow depths, and applying fertilizers before planting. Planting holes to dig 1 cubic meter to separate the topsoil from the subsoil. The weathered topsoil is more nutritious than the subsoil. When planting, the topsoil will be mixed with 20-25 kilograms of decomposed organic fertilizer, and it will be filled into the pit to about half of the depth of the pit. Step on the solid, put the seedlings into the planting hole and continue to fill the soil. Pay attention to the natural stretch of the root system to the Quartet. When the soil fills in half, gently raise the seedlings, straighten the roots, straighten the plants, and then fill in the soil. The cover soil cannot be higher than the grafting interface. In the rest of the subsoil, the center of the tree is used as the center, and the diameter and the planting hole are close to form a water dish to facilitate irrigation. Immediately after planting, it should be filled with water. After the water seeps, it should be timely covered with soil. The soil can't be higher than the grafting interface. Then a piece of plastic film covering 1 square meter will be cast in order to keep it safe. In order to prevent pouring of tree shrews, a pile of earth can be cultivated in the root or supported by bamboo rafts.
7. Post-plant management. (1) Timely dry. After planting, it must be dried in a timely manner. At full shoots, short, it is best to leave 3-6 full shoots, and make the dry height of each row roughly the same. The dry top is wrapped in plastic. (2) Watering in time. Always check the sensation of the tree tray to ensure that the soil is moist and loose until the seedlings survive.
