I. Material hanging bag 1200ml, sourced from tree hanging needle nutrient solution and hand electric drill.
Second, use a hand electric drill (generally choose 6-8 drills) to drill 3-4 cm obliquely and vertically within 30-50 cm above the tree ground, subject to xylem.
3. Dilute the prepared nutrient solution by 800- 1000 times, and dilute a bottle according to the bag hanging amount of 80- 100.
4. After the liquid medicine is diluted evenly, put it into the hanging bag, raise the pipe and needle to prevent the liquid medicine from flowing out, then insert the needle into the drilled space and lift the sling to hang it on the branch or trunk. Trees below 15CM are hung by slings, and each sling has two needles. When the two needles are on both sides of the tree, they are staggered up and down by 1-2 cm. It is recommended to use 2 hanging bags and 4 needles distributed at 90 degrees above 15CM. If there is medicine oozing from the needle after hanging the bag, you can put a piece of raw adhesive tape behind the needle, so that it will not leak if it is plugged.
5. Generally, it takes 1-2 days for each bag to be lost. Without water shortage, it will be gone in 3-5 days. After 65,438+05 days, the tree will gradually become stronger from weak, and the leaves will turn from light green to dark green and then spit out new buds. If you see that the medicine in the hanging bag is not absorbed by the trees, you can check whether the needle is blocked.
Sixth, the infusion time can be carried out at all stages of the tree growth period, preferably during the root growth period or when the tree grows poorly, such as when the branches and leaves are yellow, curly, wilting, the tree is weak or not wound. Pay attention to remember to give infusion at the initial stage of symptoms. Generally, it takes at least 15 days, and the trees can survive only if they are bagged once a week in the later period.
Through the author's practice, the survival rate is close to 100%. It is worth noting that this method is only an expedient measure for the lack of nutrition of trees, and it is not suitable for long-term use. Conventional cultivation management should be adopted for maintenance, just as people can't lose glucose without eating for a long time.
Some common measures for transplanting big trees
1 root dipping method: for young seedlings, dipping bare roots or soil balls into the soil mixed with rooting agent immediately after digging is an important measure to improve the survival rate; For Daguan seedlings, water is poured into the tree pit to make mud, and then the roots are put in to make them fully adhere to the mud, so as to avoid hanging roots and effectively prevent the tree from dying.
2. Shallow planting and high soil cultivation method: proper deep planting of trees (based on the original planting depth) is beneficial to keep alive, but after survival, due to the respiratory inhibition of roots, 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 makes up for the defects of the above planting methods. The specific method is: cultivate in high soil after shallow planting, and remove the high soil after the trees survive.
3 improve the watering method: 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.
4 trunk moisturizing method: there are mainly two methods: wrapping film and winding straw rope. Watering combined with spray drying can effectively protect the trunk from water loss and maintain the water balance of the tree.
5. Use wound smearing agent: New Chaoyang wound smearing agent-Yushang Ointment. Mainly used for big trees. After the trunk and main branches were cut off, the wound was too big. Using this medicine can not only effectively prevent wound infection, but also effectively prevent excessive evaporation of water and promote wound healing.
The use of infusion and nutrient solution for trees is of great significance to the rejuvenation of ancient trees, and also has its unique role in the survival of ordinary trees after transplantation. After punching holes in the trunk, the liquid "delivered" to the tree by the infusion bag contains various trace elements, vitamins and regulators necessary for the tree, especially the regulators contained in it have a good effect on enhancing the stress resistance of the tree.
7 Anti-transpiration agent-use of anti-steaming: Common anti-transpiration agents have two anti-transpiration principles: (1) semi-permeable membrane type. Such as chitin, is sprayed on the surface of plants to form a semi-permeable membrane, through which oxygen can pass, but carbon dioxide and water cannot. Carbon dioxide produced by plant respiration accumulates in the membrane, which increases the concentration of carbon dioxide and decreases the concentration of oxygen. This high carbon dioxide and low oxygen environment inhibits the respiration of plants, prevents the degradation of respiratory substrates such as soluble sugar, and slows down the decline of nutrients and the evaporation of water. (2) Airtight passage. Abscisic acid (ABA), polyethylene glycol, etc. It can form a film on the surface of stems and leaves or improve the sensitivity of stomata to drought, increase the closing rate of stomata under drought conditions and reduce the transpiration rate of water.
In addition, the reasonable combination of paclobutrazol, fulvic acid and potassium dihydrogen phosphate can make the chlorophyll content of plants generally high and reduce water evaporation.
Use of water-retaining agent: Water-retaining agent is mostly resin, which can't produce water by itself, but its water absorption strength is extremely amazing. This kind of product expands rapidly after absorbing water, and the water contained in it is difficult to be evaporated by the sun, but it can be effectively absorbed by the root hairs of plants, and the water release period is generally between 40 and 60 days. The degradation period of this substance in soil is generally 1-2 years, during which it can be reused. Generally speaking, the problem of water saving can be basically solved once. For transplanting big trees, water-retaining agent is mostly used in areas with severe drought or difficulty in watering (such as highways and barren hills greening). Before planting or when transplanting big trees, seeds are mixed and filled into several pits with backfill soil to resist drought.
9 the use of gene activator The main component of gene activator is abscisic acid, which can promote the activity of plant enzymes, enhance the stress resistance of plants such as drought resistance, cold resistance and disease resistance, and accelerate the growth of plants at a certain concentration. Combined with other measures, it has obvious enhancement effect and "speed-up" effect, but the effect is not obvious when used alone.
The use of 10 rooting solution: the key to ensure the survival of trees is to use rooting solution to quickly restore the roots of transplanted damaged trees. At present, the commonly used rooting agents are concentrated and made directly from the original medicine. They are small in size, easy to carry, diluted in use, low in packaging cost and lower in price and unit cost. Dilution type, the disadvantage is that the dilution ratio is small, it is not very convenient to carry, and the advantage is that it looks very affordable to users.
