Description

Spray-type three-dimensional cultivation system of cylindrical three-dimensional implants

technical field

The utility model relates to a three-dimensional cultivation system, in particular to a spray-type three-dimensional cultivation system of a cylindrical three-dimensional planting body.

Background technique

Traditional agriculture is a natural production method based on sunlight and soil matrix. The output and quality of products are restricted by the planting area and natural environmental conditions, and it is difficult to meet people's requirements for food quantity and quality.

Greenhouse cultivation gets rid of the restriction of the environment on agricultural production to a certain extent, and people can eat various vegetables or fruits at any time. Greenhouse soilless cultivation technology is a newest cultivation method researched and adopted along with the development of greenhouse production. Soilless cultivation can be roughly divided into two categories: substrate cultivation and substrateless cultivation. Substrate cultivation, that is, the root system of the crop is fixed in the substrate, and the plant absorbs the nutrient solution through the substrate. The main cultivation methods include bag cultivation, rock wool cultivation and nutrient solution film method. Substrate-free cultivation is generally called hydroponics, that is, the root system is in direct contact with the nutrient solution. In the hydroponic system, the more advanced form of nutrient solution supply is the shallow liquid flow supply method, that is, the roots of the plant are located in a relatively shallow place that flows at a certain rate. in the nutrient solution.

Plant factory is a highly specialized and modern facility agriculture developed after greenhouse cultivation. It is different from greenhouse production in that it completely gets rid of the constraints of natural conditions and climate under field production conditions, applies modern advanced technology and equipment, completely controls environmental conditions manually, and provides a balanced supply of agricultural products throughout the year. At present, high-efficiency plant factories have developed rapidly in some developed countries, realizing factory production of vegetables, edible fungi, and precious flowers and trees. One of the most important features of plant factories is the nutrient solution cultivation technology. For example, there are many methods of nutrient solution cultivation in Japan, such as NFT, Zhan liquid cultivation, and solid substrate cultivation (including rock wool cultivation, gravel cultivation, sand cultivation, etc.), among which Rock wool cultivation and NFT are the main ones, and rock wool cultivation accounts for nearly 50% of the nutrient solution cultivation area. Typical nutrient solution cultivation devices have the following forms: ① Sanshui NFT device - the cultivation bed is made of foam, with a certain slope (1/80-1/100), and the nutrient solution at the bottom is in the form of a film. Flowing, can automatically supply fertilizer, and is also equipped with a sterilizing device; ② Concorde type - use molded plastic cultivation beds, divided into several units, suitable for fruit and vegetable cultivation; ③ M type - cultivation tanks are connected by molded products made of "U"-shaped foam The planting board is also made of foam, covered with polyethylene film, which is suitable for the cultivation of leafy vegetables, especially duck celery; ④ Xinhe type equivalent exchange device - its main feature is that the cultivation tank is divided into two parts, and Equal exchange of nutrient solution to supply sufficient oxygen to the root system (②, ③, ④ all belong to Zhanye cultivation device); For the drainage pipe, lay granular rock wool pads, rock wool blocks and shaped irrigation pipes in sequence from bottom to top. The drip irrigation method is adopted, and the excess nutrient solution flows back to the sump through the drainage pipe for recycling. Plant factories mostly use mobile cultivation devices, mainly including flat, three-dimensional and inclined types. Through reasonable and dense planting, the effective cultivation area is increased. In the above-mentioned cultivation method, the roots of the plants are located in the nutrient solution most of the time, which cannot provide a better breathing environment for the plants and directly affects the metabolism rate of the plants.

The patent number is ZL96105058.6, and the date of authorization announcement is April 19, 2000. The Chinese utility model patent-plant nutrient solution atomization cultivation reactor adopts the nutrient solution atomization supply method, but the reactor is used to cultivate plants The tissue must be a closed glass tank, and the glass tank needs to ensure a certain temperature. There are multiple layers of stainless steel mesh for placing tissue blocks in the tank from top to bottom. Since the reactor adopts a multi-layer structure, spraying The nutrient solution needs to be circulated in the entire reactor driven by the propeller, and then fill the entire reactor, so that the tissue blocks on different layers can absorb the nutrient solution. In addition, because the nutrient solution atomization culture reactor is in a closed form, it needs to be ventilated during the fog stop period, which is not only complicated in structure, but also not suitable for plant cultivation.

Detailed ways

Referring now to the accompanying drawings, the spray-type three-dimensional cultivation method and system of the cylindrical three-dimensional implant described in the present invention will be described in detail.

A spray-type three-dimensional cultivation system for a cylindrical three-dimensional implant, comprising a nutrient solution aerosol supply system and the above-mentioned three-dimensional implant 51.

The nutrient solution aerosol supply system includes a nutrient solution pool 1 as shown in FIG. 4 for storing nutrient solution for cultivating plants, wherein the nutrient solution may be liquid organic fertilizer. In order to allow the nutrient solution to be sprayed out in the form of aerosol through the nozzle, it is necessary to apply high-pressure treatment to the nutrient solution flowing out of the output pipe of the nutrient solution pool 1 through the high-pressure water pump 3, that is, the input port of the high-pressure water pump 3 and the nutrient solution pool 1 is connected to the output pipeline, and the output port of the high-pressure water pump 3 is connected to the nozzle installed in the plant growth area 5, wherein the selection of the high-pressure water pump 3 needs to make the nutrient solution treated with high pressure can be sprayed in an aerosol state when it reaches the nozzle , taking into account both cost and effect, the choice of high-pressure water pump 3 can make the pressure of the nutrient solution reaching the nozzle reach 1 to 5 kg. high.

The nutrient solution aerosol supply system includes a nozzle 54 as shown in Figure 3 arranged in the plant growth area 5, and only a nozzle corresponding to a three-dimensional implant 51 is shown in Figure 3, which is arranged in the plant growth area 5 There are multiple three-dimensional implants 51 that are controlled by the same nutrient solution aerosol supply system. The connecting pipe 55 directly connected to the spray head 54 can be attached to the spray head support 53, and a part of the spray head can be directly installed on the spray head support 53, or can be suspended in the air by the shapeability of the connection pipe 55 as required, and connected The tube 55 can adjust the distance between the nozzle 54 and the three-dimensional implant 51 . In addition, the shape of the nozzle bracket 53 can be set according to the shape of the three-dimensional implant 51. For the cylindrical three-dimensional implant 51, the nozzle bracket 53 can be designed as a ring-shaped bracket structure with at least two layers.

The nutrient solution is generally a molecular cluster structure, and the root 52 of the plant needs to be decomposed and then absorbed by its own microorganisms to slow down the absorption speed of the root 52. Therefore, it can be set on the output pipeline from the nutrient solution pool 1 to the high-pressure water pump 3 Magnetization device 2, said magnetization device 2 can include two strong magnets that are attracted together to provide a strong magnetic field of 20,000 gauss to 40,000 gauss, and the magnetization device 2 can cut the nutrient solution that flows through in the form of molecular clusters The nutrient solution exists in a single molecular structure, and the nutrient solution in a single molecular structure can be directly absorbed by the root 52 without being decomposed by its own microorganisms.

In addition, a filter 4 for filtering impurities in the nutrient solution may be provided between the output port of the high-pressure water pump 3 and the nozzle 54 to avoid clogging the nozzle 54 during long-term use.

Since only a part of the nutrient solution sprayed in the three-dimensional implant 51 is absorbed by the root 52, the other part will drip through the root 52 or directly fall on the ground. The reflux tank 56, the nutrient solution to be reflux is filtered through the reflux filter 6 through the reflux tank 56, and then refluxed to the nutrient solution pool 1 after being sterilized by the reflux sterilizing device 7 for further circulation use. Wherein, the reflux sterilizing device may be an ultraviolet lamp, and the reflux filter 6 and the reflux sterilizing device 7 are preferably arranged near the nutrient solution pool 1 . Since the flow rate of the return nutrient solution needs to be limited to sterilize the return nutrient solution through the ultraviolet lamp tube, if the flow rate is too fast, the sterilization effect will not be achieved. Therefore, this problem can be solved in a simple way, that is, in the A buffer groove 10 as shown in Figure 5 is arranged next to the nutrient solution pool 1, and the inside of the buffer groove 10 is provided with a buffer wall 14, and the height of the buffer wall 14 is lower than the height of the buffer groove 10, and the buffer wall 14 will buffer The groove 10 is divided into two parts, respectively a buffer front area 101 and a buffer rear area 102, and a communication area 15, such as a communication hole, is provided between the buffer rear area 102 and the nutrient solution pool 1. After the returning nutrient solution enters the buffer front area 101 of the buffer groove 10 , it needs to cross the buffer wall 14 and enter the buffer rear area 102 , thereby reducing the flow velocity of the returning nutrient solution in the buffer groove 10 . The backflow sterilization device 7 , such as an ultraviolet lamp, can be installed on the upper part or the inner wall of the buffer tank 10 , such as being arranged on the upper part or the inner wall of the buffer tank located in the buffer front area 101 . In addition, the flow velocity of the returning nutrient solution can also be reduced in a simpler way, that is, to limit the cross-sectional area of the communication area 15 between the buffer groove and the nutrient solution pool 1 . In addition, the buffer groove 10 also has the function of precipitating impurities during deceleration through the buffer wall 14 .

In addition, the nutrient solution can be heated in winter, such as adding a heating wire to the nutrient solution pool 1, and the nutrient solution can be heated to a temperature between 5°C and 30°C. It can also be managed by a computer. According to the law of transpiration of plants, the water content and humidity of roots are adjusted, which more effectively promotes the growth of crop potential.

The method for cultivating by the spray type three-dimensional cultivation system of the cylindrical three-dimensional implant comprises the following steps:

The width of the body 513 is greater than or equal to the diameter of the planting hole, and the planting holes on the same level of the corresponding three-dimensional implant 51 can share a circle of attachments; wherein, the attachment 513 can be a thinner sponge, and the attachment 513 Need to have a certain degree of water absorption.

Automatically control the nozzle 54 to directly spray the high-pressure treated nutrient solution onto the attachment in the form of aerosol until the root of the seed grows through the attachment and extends into the interior of the three-dimensional implant, then the The nozzle sprays the nutrient solution directly to the roots of the plants until the plants are mature enough to be picked. The injection frequency of the nozzle 54 and the concentration of the injected nutrient solution can be set according to the requirements of planting different plants according to the situation known to those skilled in the art, and adjusted at different growth stages of the plants. The most basic requirement for the concentration of the nutrient solution is that when the plants are in the growth, maturity and harvest periods respectively, the concentration of the nutrient solution used in the mature period is the highest, followed by the harvest period, and the lowest in the growth period.

At first, when the nutrient solution or water is sprayed out in aerosol state through the nozzle 54 after the high-pressure treatment by the high-pressure water pump 3, the nutrient solution will permeate through the attachment to moisten the seeds, and when the seeds germinate and grow roots into the interior of the three-dimensional implant 51 After 52, the nutrient solution can be directly sprayed onto the roots 52 to provide nutrition for the plants. When the plants grow up gradually and the roots 52 become more and more developed, the attachments can be broken and dropped on the ground. This nutrient solution supply method can really get aerial roots. The nutrient solution is sprayed in the form of aerosol, which will permeate the entire internal space of the three-dimensional implant 51, that is, it can permeate the entire root space of the plant, so that the plant can obtain mineral nutrients and absorb more oxygen from the air , so the root growth is particularly developed, and the plant growth rate is 3 to 5 times that of hydroponics and land cultivation. Such as melons and fruits, through the plant nutrient liquid aerosol supply system described in the utility model, the vines can grow 2 to 3 meters in 1 month, and the roots can grow 2 to 3 meters.

When the external temperature is higher than or equal to 25°C, the three-dimensional implant is directly placed in the cultivation area, and the nutrient solution or water is sprayed through the nozzle 54 arranged in the cultivation area; when the external temperature is lower than 25°C, Then the three-dimensional implant is first placed in the nursery room for 1 to 3 days, the temperature of the nursery room needs to be kept between 25°C and 30°C, and water is sprayed through the nozzle 54 provided in the nursery room, and then placed in the For 2 to 3 days in the seedling training area, the temperature in the seedling training area decreases day by day between the temperature of the nursery room and the outside temperature. For example, if the outside temperature is 0°C, the temperature in the seedling room is 28°C. , then the temperature on the first day is 21°C, the temperature on the second day is 14°C, and the temperature on the third day is 7°C. The roots of the plants are sprayed with nutrient solution or water through the nozzles set in the seedling training area. ; Finally, the three-dimensional implant is placed in the cultivation area, and the nutrient solution or water is sprayed through the nozzle 54 arranged in the cultivation area until the plants are mature and can be picked.

In addition, the seeds or seedlings of different plants can be implanted on the three-dimensional implant 51, such as seeds of fruits and vegetables can be implanted in the planting holes on the top, and leafy vegetables can be implanted in the planting holes on the side walls. The seeds of class or rhizome, wherein, also can be divided into the upper part and the lower part of planting the seeds of different vegetable classes on the side wall. When the seeds of fruit vegetables take root and germinate, and after the vines grow, the vines are hung on the trellis above the three-dimensional planting body, so that the leafy vegetables below can rely on the trellis for shade. Through the nutrient solution aerosol supply system described in the utility model, the vines of melons and fruits can grow 2 to 3 meters, and the roots can grow 2 to 3 meters in one month.
