Methods of keeping water and keeping alive for planting trees in barren hills Share five methods of transplanting big trees to keep alive.

The traditional watering method is from top to bottom and from outside to inside. It's easy to get drenched the first time. If the soil is too sticky and hardened, it will be difficult to pour it thoroughly for the second time, leading to the death of trees.

The improved watering method is "from bottom to top, from inside to outside". Specific practice: connect a water pipe spray gun with a length of about 1 m to the head of a plastic water pipe, insert it into the depth of the soil layer and water it thoroughly without extending the watering time.

2, shallow planting high soil cultivation method.

Proper deep planting of trees (on the basis of the original planting depth) is beneficial to keep alive, but after survival, due to the inhibition of root respiration, the vitality is not strong, which is not conducive to growth; Proper shallow planting of trees is not conducive to keeping alive, but after survival, the roots grow faster because of smooth breathing.

The method of shallow planting and high soil cultivation just makes up for the defects of the above planting methods. The specific methods are as follows: implement high soil cultivation after shallow planting (equivalent to deep planting, which is conducive to keeping alive), and remove high soil cultivation after trees survive (equivalent to shallow planting, which is conducive to good breathing of roots).

3. Root soaking method.

Before the seedlings are dipped in mud, the soil particles and stones attached to the roots must be shaken off, and then the seedlings should be bundled into small bundles. The rope should be located above the roots, and attention should be paid to the roots. If the single seedling is too big, there is no need to bind it. It is best to dip it in mud at any time.

The method of making mud is to select a partially viscous loam plot and dig a circular pit on the ground. The size of the pit depends on the number of seedlings dipped in mud. First shovel out the mud in the pit, then water and stir it to make it look like mud, and be careful not to be too thick or too thin.

In order to test whether the mud is suitable, take a branch with a length of 30 cm and a thick finger and insert Camellia seedlings vertically into the mud. If the branches fall slowly, it means that the concentration of mud is just right.

4, trunk moisturizing method.

There are roughly three ways to moisturize the trunk, and the appropriate choice should be made according to the specific situation in actual operation.

(1) Wrap the straw and bind the film: firstly, wrap the trunk with straw curtain or directly with straw, and then fix it with thin straw rope. Then spray the straw with a hose or sprayer, or soak the straw curtain or straw and wrap it. Then wrap the plastic film around the straw curtain or straw, and finally tie the film to the trunk.

Let the film spread out near the soil ball at the lower part of the trunk, cover the bottom with plastic film together with the dry bag after covering with soil and watering. The periphery of the plastic film is closely combined with the soil, so that the temperature and humidity of the trunk space of the package can be ensured by adjusting the soil temperature, and the work of supplementary watering can be omitted.

(2) Tie rope and film: firstly, tie the trunk firmly with thick straw rope, water the straw rope, and tie plastic film to keep moisture. The ground is covered with plastic film, and the method of pressing soil at the bottom is the same as the first method, which has obvious moisturizing and temperature regulation effect and is also conducive to survival.

(3) Bundle grass, film and cloth: In some beautiful landscapes, because wrapping grass and film will affect the landscape effect, you can wrap a layer of coarse white linen around the trunk and trees after wrapping grass and film.

This can not only coordinate with the environment, but also prevent the temperature in the film from being too high in summer, which is also good for the survival of the trunk.

5, the use of tree hanging needles.

Tree nutrient solution, also Screaming Trees infusion, tree infusion bag liquid. Using nutrient solution to "infuse" trees is of great significance for rejuvenating ancient trees, and it also plays a unique role in keeping ordinary trees alive after transplantation.

With people living in a beautiful, green, clean and fragrant environment, many green trees are transplanted out of season in cities every year, but the transplantation of big trees will damage their roots and lead to their weak ability to absorb water and nutrients. In addition, some water evaporates from the leaves, which makes the newly transplanted trees dry up and die easily. Therefore, it is a good way to supplement the nutrition of trees with the nutrient solution of trees as a direct way.
