How to improve the survival rate of transplanting, how to improve the survival rate of transplanted

After planting, mulberry seedlings often fail to germinate normally, or grow poorly after germination, and eventually die. Especially in the dry areas of winter and spring, the survival rate is low, and if the lack of plants is serious, it will affect the normal yield of mulberry orchards. To improve the survival rate of mulberry planting, attention should be paid to the following tasks.

Seedling quality. Generally speaking, large seedlings and strong seedlings are selected, which have strong resistance to adverse environments, and are not easy to lose water and dry up after planting in arid areas; It is advisable to choose mulberry seedlings with a root neck of more than 7 mm, and the survival rate is higher. In order to plant before the soil freezes, the northern silkworm area began to purchase mulberry seedlings in late October, at this time, the mulberry seedlings in Zhejiang have not yet fallen leaves, and the sap flow is relatively vigorous, and the early seedlings have a certain impact on the survival rate of planting.

Improper storage and treatment from seedlings to planting in winter can easily be frozen or dry up due to water loss; If the temperature rises quickly in spring, the mulberry seedlings are easy to germinate, which will seriously affect the survival rate of mulberry seedlings after planting.

Mulberry seedling treatment. Most of the newly built mulberry orchards in the western silkworm area are transported from Zhejiang and other places, and the seedling roots dry up to varying degrees due to long-distance transportation, which is one of the main reasons for the low survival rate. After the mulberry seedlings arrive, the seedling roots can be immersed in mud water for 12 24 hours and then taken out, and placed in a cool place for later use, so that the seedling roots can absorb an appropriate amount of water.

Planting period and method.

In the arid areas of winter and spring, planting before germination in spring is shorter before the rainy season, which can effectively reduce the water loss of mulberry seedlings. The planting depth should be appropriately deep to reduce the water loss of mulberry roots.

Post-planting management. In arid areas and difficult watering, it can be watered thoroughly once after planting and then covered with mulch, so as to reduce ground water evaporation, keep the soil moist, and significantly improve the survival rate.

In-situ seedlings and transplanting in the rainy season.

In dry areas in winter and spring, if there are no irrigation conditions, you can choose to plant mulberry in the rainy season. At this time, it is in the mulberry growth period, it is best to raise seedlings on the spot, dig and plant, and leave only a small number of seedlings and leaves when transplanting, so as to reduce the consumption of water by foliar transpiration, prevent the seedlings from withering, and improve the survival rate. It has been adopted in Shandong, Yunnan, Sichuan and other places.

First, the right place and the right tree. Some tree species prefer to be loose.

Soil. It is not resistant to water damage, and some tree species are not shade tolerant, so it is necessary to arrange tree species for the right place and suitable tree.

Second, the right tree is timely. Some tree species should be well equipped with a transplanting period that is easy to survive. For example, locust trees have a high survival rate after germination, while conifers can be planted in autumn.

If a tree planted in autumn has small shoots and leaves in early winter, it should be retained, because new roots need "kinetins" to grow, and only new shoots can produce these kinetins to transport to the roots.

How to improve the survival rate of plant transplanting during the growth period.

Therefore, in order to reduce a large amount of evapiration of leaves, a part of the branches and leaves should be cut off, so as to ensure the balance between water absorption and consumption, and prevent plant wilting Improve the survival rate of plants This is also the reason why people often transplant plants on rainy days or in the evening, and shade the transplanted plants

When transplanting plants, choose to transplant on a cloudy day or in the evening, remove part of the branches and leaves, can reduce the transpiration of the plant, reduce the loss of water, and is conducive to the survival of the transplanted plant The main part of the root water absorption is the young roots and root hairs, so when transplanting the plant, it is necessary to transplant with soil to protect the young roots and root hairs, which is conducive to the root water absorption and improves the survival rate

When transplanting plants, if you want to improve the survival rate of transplanting, then first of all, you should know that the roots should keep a certain amount of soil when transplanting, so that the roots are kept moist, and you should pay attention to sprinkling more rooting powder when you are there.

First of all, it is necessary to transplant with soil, secondly, not to transplant at too high temperatures, and thirdly, to water thoroughly after transplanting. Fourth, you can block out the sun a little a few days ago.

I think when transplanting plants, we must pay attention to its root system and ensure its root system to ensure the survival rate.

What can be done to transplant plants to improve the survival rate of plants? I think it's best to add some rooting water when you transplant the plant, and then this may increase its survival rate.

Methods for transplanting trees with a high survival rate: 1. Watering the cofferdam, enclosing a 15-20cm high weir around the trees, and watering regularly; 2. Wrap the trunk with straw rope, moisturizing cotton, straw mat, etc.; 3. The support is stable, and the support is made at the 2 3 or above the trunk of the tree or the fork of the first main branch; 4. Infusion of nutrient solution to replenish nutrients and water to the trunk in time.

The height of the cofferdam shall not be less than 15-20cm, and the water shall not run or leak. Watering in time, the sooner the better, the first permeable watering time should not exceed 24 hours, 3-5 days after the second watering, 7-10 days after the third watering.

For young, smooth, thin-skinned trees, after planting, you can wrap the trunk with materials with good moisturizing and thermal insulation properties, such as straw ropes, moisturizing cotton, straw mats, etc., which can prevent sunburn and frost damage. In summer, pay attention to the sterilization of the tree with bactericidal gold before wrapping, otherwise it is easy to cause fungal diseases.

Bracing can maintain the stability of the newly planted tree and prevent it from lodging and sinking. Generally speaking, the support should not be tied to the 2 3 above the trunk of the tree or the fork of the first main branch, and the lower part should be fixed outside the tree hole.

If it is a large tree, it is best to use nutrient solution for infusion after planting, so as to replenish nutrients and water in time to promote the rooting and germination of the tree and improve the survival rate of transplanting. The roots can also be watered with rooting powder and fungicides to promote rapid root development and prevent root rot.

Transplanting trees to improve the survival rate can irrigate the large trees, and cut off the roots of the large trees according to the size of the reserved soil balls.

For large trees that need to be cut off, 3-5 main branches are usually selected at 2-3m from the main trunk, sawn at a distance of 55-60cm from the main trunk, and the saw edge is tied with plastic film immediately after cutting. The best time to move and plant is in early spring and late autumn after leaf fall to before the soil freezes, when the flow of sap is slow and can reduce the evaporation of tree water.

When transplanting large trees, it is necessary to dig the transplant hole in advance, and plant the large trees as soon as possible after they are transported. The three-column bracket fixation method is used to firmly support the tree to ensure the stability of the tree, and new technology products such as water-retaining agent and rooting agent are introduced, and the root system of the tree can be removed only after 1 year. If the branches are not thinned or the amount of thinning is small, it is necessary to do a good job of shading and searching for Qingyin in time.

Trees transplanted in autumn are relatively less resistant to cold because they have just been planted, so it is important to take measures to protect against the cold in winter.

The reason for the low survival rate of transplanted trees in the high temperature season

It is not the best season for transplanting seedlings, and seedlings are in the growth stage. The best transplanting season for seedlings is in their dormant period, and spring and autumn are the best, because at this time the seedlings store more nutrients in the body, the fluid flow in the body is relatively slow, whether it is pruning or transplanting wounds heal faster, and the loss of nutrients is relatively small, which is very conducive to the survival of trees.

In the summer high temperature period, the pruning incision on the branch is easy to lose nutrients, and many germs and pests will invade from the wound. The wound on the root system also recovers slowly, and if the water content in the rhizosphere environment is relatively high, the high temperature and high humidity environment can easily cause the seedlings to rot the root system.

Therefore, transplanting trees in the high temperature season, the nutrient loss of the seedlings themselves will be more serious, the rooting ability will not be too good, and there is not too much nutrients stored in the body.

In order to better improve the survival rate of apple seedlings, after planting, the soil layer management method must follow. Generally speaking, it is easier to improve the survival rate of cooked soil planting, and it is better to plant cooked soil without too much soil layer before planting, especially if the soil stratification that cannot be wet is destroyed.

If it is a newly ploughed soil layer, the height of the ploughed soil layer can not exceed 60 cm, because after more than 60 cm, it is very likely to cause the indiscriminate use of the soil hierarchical order to be disrupted, resulting in the destruction of the surface of the decay layer, which is not conducive to the digestion and absorption of nutrients after planting, is not conducive to the development trend of the root system, it is difficult to improve the survival rate.

Organic fertilizer is very important to improve the survival rate of apple seedlings. In the case of carrying out fruit seedling planting, it should be used with caution. In particular, to increase land resources, in other words, newly cultivated land resources, in the case of planting fruit seedlings, it is also necessary to carefully apply organic fertilizers, naturally, chemical pesticides are best if they can be dispensed with.

Because the newly opened land resources are usually preserved in it with a certain fertilizer effect, so the conditions for the growth and development of small seedlings have already been there, if the land resources are excessively poor, the moderate application of organic fertilizer can be, and the chemical pesticides are better to use less in the new land resources, otherwise there may be adverse reactions, such as the development trend of the root system, which is not conducive to the budding growth and development of willow seedlings.

The final is watering, after the willow seedlings are planted, in order to better improve the survival rate, watering must be cautious. Because the willow seedling itself is relatively small, the water is very fragile, so the case of watering must not be a lot of tap water, because a lot of tap water will cause the root system to soak in the soil with too much temperature for a long time, which is not conducive to the root system to inhale, but is not conducive to growth and development.

In other words, you should not over-water, especially in the spring, when the rainfall is more abundant, so the watering depends on the situation. There are also insecticides and rooting agents, it should be said that before the seedlings are planted, they should be soaked in the dilution solution of insecticides and rooting agents for 24 hours, so that after planting, they can prevent diseases and improve the survival rate.

The survival rate of greening seedlings suffers from various factors, such as whether the root system of greening seedlings is relatively developed, whether it is water shortage, regional temperature, environmental humidity, soil layer type and other factors are harmful, in the case of transplantation, try to ensure that the harm of unfavorable conditions is minimized, and then enhance the survival rate of greening seedlings, reduce the property loss of farmers, and complete the ideal of poverty alleviation and prosperity!

If you want to improve the survival rate, you should water the saplings immediately after planting, and you should also make sure that the saplings are in good condition when planting them.

The first thing is to keep some of the soil at the roots, when transplanting, we must pay attention to the right time, we must pay attention to the right temperature, and then we should do a good job of pruning and rhizome protection, and we must design the rules in advance.

When transplanting seedlings, some cotton gauze should be wrapped around the roots of the seedlings, and it is best to water them more so as to improve the survival rate.

When transplanting saplings, a little soil should be brought to the roots of the saplings, and a pit should be dug in advance before transplanting, and some nutrient solution can be sprinkled in the pit to improve the survival rate of saplings.

You know, pay attention to the selection of seedlings, pay attention to the time of transplantation, be sure to pay attention to the temperature of transplantation, pay attention to watering, pay attention to fertilization, and pay attention to the surrounding situation.

I think the best thing to do is to choose to transplant in the spring and water it a few times after transplanting, so that the survival rate will be higher.

Pruning shape, pruning the branches and leaves in advance before transplanting, and shaping the soil at the roots into a small circle shape; The application of base fertilizer is suitable for the application of treated decomposed farmhouse fertilizer as base fertilizer; Planting to make a pit, the bottom fertilizer can be planted after the application is completed, the planting process needs to compact the soil, and make a small flat pit in the first place; In the later stage of management, the soil needs to be watered immediately after planting to ensure that the slightly wet state is maintained.

Before transplanting the fruit tree, prune the branches and leaves of the fruit tree in advance, and then use tools to shape the soil at the root, and the shape can be a small round shape, and the bottom of the root is recommended to be shaped into a conical style, which can facilitate the smooth transportation of the fruit tree in the process of transplanting.

Before transplanting and planting fruit trees, it is necessary to apply some fertilizer in the pre-dug soil pit as base fertilizer, suitable for the use of organic fertilizer after decomposing treatment, the amount of fertilizer needs to be judged according to the growth size of the fruit tree, the large is more and the small is less, and the bottom fertilizer is applied to 10 cm of soil after the application is completed.

After the bottom fertilizer is applied, the fruit trees that need to be transplanted can be put into the soil pit, and the soil pit is covered and filled completely, note that when filling the soil in the soil pit, it is necessary to cover the edge and compact the soil, and make a small flat pit in the middle of the fruit tree planting after completion, so as to facilitate watering the fruit trees.

If you want to transplant fruit trees to live tall, you also need to do a good job in later management, water the plants immediately after planting, the amount of water needs to be able to water the soil to keep it slightly wet, to ensure that the transplanted fruit tree roots are in full contact with the soil, and the light is too strong during the growth period, and you can use shade nets to protect the plants.
