Description

A water-saving maintenance device for transplanting garden seedlings

technical field

The utility model relates to a nursery stock maintenance device, in particular to a water-saving maintenance device for transplanting garden seedlings, which belongs to the municipal engineering construction content, and is particularly suitable for urban garden landscape construction in my country.

Background technique

At present, my country is vigorously promoting the process of urbanization, improving the living environment of urban people, strengthening and improving the construction of urban landscapes, and the transplanting and maintenance of large trees has become a major and difficult point in the construction of landscapes, especially the survival of off-season transplants of large trees. maintenance.

At present, the commonly used means of transplanting and surviving off-season big trees are:

1. Heavy pruning (crown cutting)

Any form of transplantation will damage the root system of the tree. In order to ensure the balance of income and expenditure in the large tree, people often take technical measures such as cutting the root in advance, cutting the stem and shrinking the branch, picking a large number of plant branches and leaves, and encapsulating the cross section; notch. In order to maintain the water balance of the tree body, at present when large trees are transplanted, heavy pruning is often used, but after heavy pruning, the ornamental value of seedlings will be directly affected. If heavy pruning is not carried out, the survival rate of seedlings will be greatly reduced, causing serious damage. economic and ecological impacts.

2. Set up sunshade net

In northern summer, the temperature is high and the light is strong. In the out-of-season transplant, the high temperature of the sun will burn the delicate branches and leaves of the plants. Set up sunshade facilities for transplanted seedlings to create a relatively low temperature microclimate. In order to reduce water evaporation in seedling transplantation, sunshade nets can be set up after transplanting large trees, but setting up sunshade nets not only affects the ornamental value, but also has a higher cost.

3. Artificial pouring and water spraying

Water three times, the first water should not be too large, and the water should be poured slowly to make the soil sink. Generally, the second water should be completed within two or three days after planting, and the third water should be completed within a week. The amount of water should be sufficient, and after each watering, attention should be paid to rectifying the weir, filling soil to plug leaks, and the seedlings caused by watering should be straightened in time. After the big tree is transplanted, it is generally watered manually and sprayed in a timely manner. The large amount of artificial watered water will cause the soil layer at the root to collapse, which will directly cause the core soil of the soil ball to separate from the root system; A large amount forms surface runoff and causes soil erosion.

Due to the damaged root system of newly transplanted large trees, the ability to absorb water is reduced, so ensuring sufficient water is the key to ensuring the survival of trees. In addition to watering at the right time, spray water mist to moisturize or wrap the trunk according to the tree species and weather conditions.

Utility model content

The purpose of this utility model is to propose a water-saving maintenance device for transplanting garden seedlings to improve Survival rate of seedlings after transplanting.

To achieve the above purpose, the utility model provides a water-saving maintenance device for transplanting garden seedlings, the water-saving maintenance device includes a power hub mechanism connected to a water source, a pipeline mechanism connected to the power hub mechanism , the micro sprinkler head that links to each other with described pipeline mechanism, described power hinge mechanism comprises booster pump and the filter that links to each other with described booster pump, and described pipeline mechanism includes a filter that is arranged between described filter and seedling bottom Grade pipeline, the secondary pipeline that is connected with described primary pipeline and along the nursery stock trunk upwards, the tertiary pipeline that is arranged between described secondary pipeline and micro sprinkler head, and described micro sprinkler head is arranged on described nursery stock top 30 ~70cm.

Preferably, the filtering aperture of the filter is smaller than that of the micro-spray head, and a pressure gauge and a blowdown valve are also provided near the filter.

Preferably, the power pivot mechanism further includes a timing controller connected with the booster pump.

Preferably, when the micro-spray head is installed, the micro-spray head is first bound to the bamboo pole with a cable tie, and then the bamboo pole is bound to the seedling trunk.

Preferably, for seedlings with a crown width > 4m, a rotary micro-sprinkler head is used; for seedlings with a crown width < 4m, a refracting micro-sprinkler head is used.

Based on the above-mentioned technical scheme, the utility model has the advantages of:

Forming a microclimate around the tree: After the micro-spraying is turned on, the entire canopy is surrounded by water vapor, and the air humidity, temperature, ground temperature, and soil moisture content around the canopy and trunk have changed accordingly. In the dry and high temperature season, a unique high humidity and low temperature, relatively stable microclimate environment is formed around the trees, which is very conducive to the rooting and survival of the trees.

Canopy temperature and humidity changes: The relative humidity in the micro-spray area was significantly higher than the traditional treatment of wrapping the trunk and artificial water spraying. The temperature can be reduced by more than 5°C.

Changes in ground temperature and soil surface structure: During the high temperature period at noon, the ground temperature in the micro-sprayed area can be reduced by more than 10°C. And because of the large specific heat capacity of water, the temperature change in the micro-spray area is relatively stable. Spray water manually with a hose, the water droplets are large, it is easy to produce surface runoff, and the soil surface is easy to harden, which will affect the growth of seedling roots and the normal absorption of water and nutrients; The change of low temperature in the soil layer with a depth of 0-20cm is also relatively stable, which is conducive to maintaining a certain water content in the soil, which is conducive to strengthening the activities of microorganisms, and the soil is not easy to compact, which is more conducive to the germination of new roots and the growth of root systems.

Improve the survival rate: micro-sprinkler irrigation can ensure sufficient water supply for the growth of new roots, root growth and vegetative organ growth of large trees, and form a local humid microclimate that is conducive to the growth of seedlings. The suitable temperature for photosynthesis is 20-25°C, and the extreme temperature is 40-50°C. Avoid water retting, causing root death, micro-spray watering can quickly absorb and spread, and surface water can quickly evaporate, preventing root rot caused by high temperature and high humidity; for the same tree species, using micro-spray can significantly improve tree transplanting survival rate.

Avoid excessive pruning: In the traditional large tree transplanting process, in order to ensure the water balance between the underground part and the aboveground part (crown) of the newly transplanted trees, the crown must be pruned. However, if excessive pruning is performed to reduce transpiration, it will affect the greening effect and lose the role of big trees in "standing on the ground and forming a landscape". At the same time, through photosynthesis and foliar fertilization, the canopy can deliver nutrients to the underground part and promote the rooting of the underground part, thereby ensuring the survival of the transplanted tree. However, using the micro-sprinkler irrigation technology for large trees, as long as the water source is sufficient, pruning can be minimized or even not pruned.

Reduce maintenance costs: The micro-sprinkler irrigation technology for big trees mainly reduces maintenance costs through two aspects, one is low investment itself, and the other is to save labor input for manual watering.

Form a special landscape effect: After the micro-sprinkler irrigation is turned on, the big trees in the entire micro-spray area will be surrounded by the sprayed water vapor, and the crown and trunk will also become wet, forming a special landscape effect similar to a tropical rainforest. With traditional hose watering, from one side to the other, the water above the ground in the initial area will evaporate again, which cannot achieve such an effect.

detailed description

The technical solutions of the present utility model will be further described in detail through the drawings and embodiments below.

The utility model provides a water-saving maintenance device for transplanting garden seedlings, as shown in Figure 1, which shows a preferred implementation of the utility model. Specifically, the water-saving maintenance device includes a power pivot mechanism connected to the water source 1, a pipeline mechanism connected to the power pivot mechanism, and a micro-spray head 9 connected to the pipeline mechanism. The power pivot mechanism includes a pressurized The pump 3 and the filter 2 connected to the booster pump 3, the pipeline mechanism includes a primary pipeline 5 arranged between the filter 2 and the bottom of the nursery stock 10, connected with the primary pipeline 5 and along the The secondary pipeline 6 that the trunk of the nursery stock 10 is arranged upwards, the tertiary pipeline 8 that is arranged between the secondary pipeline 6 and the micro-spray head 9, and the micro-spray head 9 is arranged at 30-70 cm above the seedling stock 10.

After the device is in operation, water is sprayed into water mist by the micro-spray nozzle 9 to form a microclimate around the tree body. After the micro-spray is turned on, the entire canopy is surrounded by water vapor, and the air humidity, air temperature, ground temperature and soil moisture content around the canopy and trunk have changed accordingly. In the dry and high temperature season, a unique high humidity and low temperature, relatively stable microclimate environment is formed around the trees, which is very conducive to the rooting and survival of the trees. Canopy temperature and humidity changes: The relative humidity in the micro-spray area was significantly higher than the traditional treatment of wrapping the trunk and artificial water spraying. The temperature can be reduced by more than 5°C. Changes in ground temperature and soil surface structure: During the high temperature period at noon, the ground temperature in the micro-sprayed area can be reduced by more than 10°C. And because of the large specific heat capacity of water, the temperature change in the micro-spray area is relatively stable. Spray water manually with a hose, the water droplets are large, it is easy to produce surface runoff, and the soil surface is easy to harden, which will affect the growth of seedling roots and the normal absorption of water and nutrients; The change of low temperature in the soil layer with a depth of 0-20cm is also relatively stable, which is conducive to maintaining a certain water content in the soil, which is conducive to strengthening the activities of microorganisms, and the soil is not easy to compact, which is more conducive to the germination of new roots and the growth of root systems.

The water source 1 requires continuous water supply and a certain depth to ensure that the water inlet of the booster pump 3 is not exposed and sucks in air, and clean water sources should be selected as far as possible, such as river water, lake water, well water, fire water, etc. . During the construction process, the water source can be adjusted according to the construction progress. If there is construction tap water, it can be directly connected to the construction tap water; After the nursery stock 10 enters the normal maintenance management in the later stage, the water source 1 can be directly incorporated into the municipal tap water system, and tap water is used for irrigation.

As shown in FIG. 1 , the power pivot mechanism includes a booster pump 3 and a filter 2 connected to the booster pump 3 , which provides the entire water-saving maintenance device with an appropriate amount of water, moisture with a certain pressure and cleanliness. The booster pump 3 is the core water lifting and pressurizing facility of the whole device. The model can be selected according to the specific situation (specific indicators include power, water output, head, etc.). Mature communities can directly connect the main water source to tap water, reclaimed water, etc. Pressurized water source. The main function of the filter 2 is to purify water. In order to prevent the micro-spray head 9 from clogging, the filter aperture of the filter 2 is smaller than the aperture of the micro-spray head 9 . If there are many impurities in the water, a pressure gauge and a drain valve are also provided near the filter 2, and they are cleaned regularly to prevent the main water supply pipe from bursting due to the increase in water pressure after the impurities increase. Preferably, the power pivot mechanism further includes a timing controller 4 connected to the booster pump 3 , and the booster pump 3 is controlled by setting the time.

As shown in Figure 1, the pipeline mechanism transports water to all irrigation positions that need to be reached. And the secondary pipeline 6 arranged upward along the trunk of the nursery stock 10, the tertiary pipeline 8 arranged between the secondary pipeline 6 and the micro spray head 9.

Specifically, the primary pipeline 5 generally adopts a large-diameter pipeline (the size of the caliber is calculated according to the required water volume and water pressure of the entire irrigation area) to connect the power hub mechanism with the entire irrigation system, and is generally buried underground to prevent Heavy machinery crushes it as it passes by. Described secondary pipeline 6 generally adopts smaller caliber pipeline, leads to the top of nursery stock 10 in order to connect primary pipeline 5 by reducing tee, and it is fixed on the trunk by cable tie. The tertiary pipeline 8 generally adopts the smallest caliber pipeline, and is directly connected to the secondary pipeline 6 through a socket.

The micro-sprinkler 9 is directly connected to the tertiary pipeline 8 through a socket. In order to allow the micro-spray to spray as large a range as possible, it needs to be installed on the top of the tree at a certain height (generally 30 to 70 cm, depending on the specific tree shape). ). The water droplets/water mist sprayed by the micro-spray head are in the horizontal direction, so it needs to be adjusted to the vertical direction during installation. Preferably, when the micro-spray head 9 is installed, the micro-spray head is first bound on the bamboo pole with a cable tie, and then the bamboo pole is bound on the seedling 10 trunk. Concrete method is to bind micro-spray head 9 on the bamboo pole of suitable length earlier with cable tie, then bamboo pole is bound on the trunk of nursery stock 10.

After the micro-spray irrigation is turned on, the large trees in the entire micro-spray area are surrounded by sprayed water vapor, and the crowns and trunks of the trees also become moist, forming a special landscape effect similar to that of a tropical rainforest. And through the traditional hose watering, pouring from one side to the other side, the water above the ground in the initial area will evaporate again.

Further, there are two types of micro-sprinklers used in big tree micro-spraying, namely rotary micro-sprinklers (spraying diameter 5-6m) and refracting micro-sprinkling heads (spraying diameter 2.5-3m). Preferably, for seedlings 10 with a crown width>4m, a rotating micro-sprinkler head is used; for seedlings 10 with a crown width<4m, a refracting micro-sprinkler head is used. Therefore, under normal circumstances, for full-canopy transplanting and less pruning, choose the rotary micro-sprinkler to moisturize the leaves and trunk; for severe pruning, with few or no leaves, choose the refracting micro-sprinkler to moisturize the trunk. For multi-headed trees, if the distance between branches is small, less than 4m, you can add a horizontal bamboo pole and set the micro-sprinkler at the upper center of the entire tree. For those with multiple heads and a large distance between branches, greater than 4m, it is necessary to add micro-sprinklers on the branches.

Of course, it is not difficult for those skilled in the art to understand that for the arranged water-saving maintenance device, the first-level pipeline can also be directly incorporated into the water meter well of municipal tap water, and the second-level pipeline on a single seedling can also be directly connected through the adapter. Connects to quick dispensers inside landscaping.

The water-saving maintenance device of the present utility model can be set through the following steps:

1. Under the condition that the pressure and range can meet the requirements of micro-spraying, organically combine the first-level pipeline of the device with the green water supply system to reduce construction costs.

2. After the seedlings are transported to the construction site, before planting and hoisting, bind the tertiary pipes (installed with micro-spray heads) to light support materials such as bamboo poles and thin wooden sticks, and then fix the bound tertiary pipes to the seedlings On the branches, the micro-sprinklers are required to protrude from the top of the branches by 30-70cm, and the number of tertiary pipes and micro-sprinklers is determined according to the size of the crown of the seedlings;

3. Plant the seedlings bound with the micro-sprinklers at the designated place according to the specifications, and connect the secondary pipeline to the primary pipeline after the planting is completed.

Because micro-sprinkler irrigation can ensure sufficient water supply for large trees to germinate new roots, root growth and vegetative organ growth, and form a local humid microclimate that is conducive to the growth of seedlings. The suitable temperature for photosynthesis is 20-25°C, and the extreme temperature is 40-50°C. Avoid water retting, causing root death, micro-spray watering can quickly absorb and spread, and surface water can quickly evaporate, preventing root rot caused by high temperature and high humidity; for the same tree species, using micro-spray can significantly improve tree transplanting survival rate.

In the traditional large tree transplanting process, in order to ensure the water balance of the underground part and the aboveground part (crown) of the newly transplanted trees, the crown must be pruned. However, if excessive pruning is performed to reduce transpiration, it will affect the greening effect and lose the role of big trees in "standing on the ground and forming a landscape". At the same time, through photosynthesis and foliar fertilization, the canopy can deliver nutrients to the underground part and promote the rooting of the underground part, thereby ensuring the survival of the transplanted tree. However, using the micro-sprinkler irrigation technology for large trees, as long as the water source is sufficient, pruning can be minimized or even not pruned, which reduces labor input for manual watering.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model and not limit it; although the utility model has been described in detail with reference to the preferred embodiment, those of ordinary skill in the art should understand that: still The specific implementation of the utility model can be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solution of the utility model, all of them should be included in the scope of the technical solution claimed by the utility model.
