Description

Technical Field

[0001] The present invention relates to the technical field of agricultural hydroponic cultivation, and more particularly to a hydroponic kale planting device and method. Background Art

[0002] Chinese kale is one of the biennial herbaceous cabbage vegetables of the genus Brassica in the family Cruciferae. Its growth process has specific physiological requirements. Compared with soil-grown Chinese kale, hydroponic Chinese kale has significant advantages. First, hydroponic technology can avoid pests and pesticide pollution in the soil, thereby producing pollution-free and pollution-free high-quality Chinese kale. Second, hydroponic technology can accurately control the growth environment and nutrient solution composition of Chinese kale, achieving rapid growth and high yield of Chinese kale.

[0003] The growth of kale before the leaf cluster growth period is very small, and 80% of the growth is concentrated in the cauliflower formation period. Therefore, in cultivation, it is necessary to conform to this physiological characteristic and provide sufficient nutrients and a suitable growth environment. In addition, kale's absorption of nitrogen, phosphorus and potassium gradually increases during the growth process, and the absorption is the largest during the cauliflower formation period, which also requires targeted nutrient solution management during the hydroponic process.

[0004] In the existing hydroponic cultivation of kale, most of them are supplemented by a floating plate and a hydroponic basket. The buoyancy of the floating plate adjusts the height of the seedling in the hydroponic basket according to the actual water level to ensure that the roots of the seedlings remain below the water surface to maintain a good planting environment for water and nutrient replenishment. However, in actual use of the hydroponic device, because the hydroponic method can provide plants with sufficient water and necessary nutrients, the root system of the same plant is usually more developed when hydroponically cultivated compared to traditional soil cultivation. In the traditional basket-shaped hydroponic container, roots are interspersed along the mesh holes to fix the relative position of the roots of the hydroponic plants and the container, weakening or even losing the adjustment of the plant position by the floating plate, which easily causes part of the plant root system to be unable to submerge under the water surface or part of the plant body to be immersed under the water surface. In this way, not only will the root zone rot or the growth state of the plant weaken in the hydroponic environment, but also the mature plants in this state need to be equipped with scissors to cut off the roots when picking to facilitate the complete removal of the plants, and the hydroponic basket after the plants are taken out needs to carefully remove the residual roots to prevent them from affecting subsequent planting.

[0029] Technical effects and advantages of the present invention:

[0030] 1. The present invention improves the structure of the circulating rotary cultivation member. The circulating water pump pumps the nutrient solution in the water storage tank through the water diversion pipe to the topmost cultivation bin position. The hydroponic solution flows into the bottom tank through the water seepage hole through the hydroponic pipe and is replenished into the inner cavity of the outer cup body through the water filter. The protective bottom member is installed in the outer cup body, so that the inner cavity of the overall planting cup forms a fence opening without a traditional hydroponic container, and cooperates with the arc bottom surface to form a smooth inner wall of the planting cup. During the hydroponic process, the growth of the kale roots will not form adhesion and interweaving with the inner wall of the planting cup, and the roots of the kale seedlings transplanted to the floating board are always kept floating in the hydroponic solution in the inner cavity of the planting cup, avoiding the traditional hydroponic device from grabbing the hydroponic container due to the root system, effectively avoiding the possible rot of the root zone or the weakening of the plant growth state, and providing a simple method for subsequent picking;

[0031] 2. The present invention adds a water-blocking baffle on the inner wall of the hydroponic tube, which can maintain the water level when the hydroponic solution enters the inner cavity of the hydroponic tube, so as to ensure that the hydroponic solution can be smoothly added into the planting cup through the water seepage hole, and the arc-shaped water-blocking baffle does not affect the normal circulation of the hydroponic solution and prevents the high-speed water flow from directly impacting the bottom of the planting cup extending through the installation groove, effectively preventing the loosening of the installation position of the planting cup and the installation groove caused by long-term water flow impact, and preventing the hydroponic solution from leaking out from there;

[0032] 3. The limit plate of the present invention is arranged in a raised position in the inner cavity of the outer cup body, which can limit the turning space of the floating board in the outer cup body. That is, when water flows into the hydroponic solution in the inner cavity of the outer cup body through the seepage holes and acts on the floating board with transplanted seedlings, especially when the transplanted kale seedlings are relatively low, there will be no death of seedlings due to the turning / tilting of the floating board, which will affect the smooth progress of the hydroponic work.

With the water flow guidance and the action of its own weight, the water flows through the cultivation bins 201 of the longitudinal step height in sequence, and finally passes through the cultivation bin 201 at the bottom and is discharged back to the water storage tank 30 through the drainage pipe 206, thereby forming a complete hydroponic solution passage, ensuring that the roots of kale have sufficient oxygen supply and timely supply of nutrients for hydroponic growth, preventing the precipitation of nutrients and maintaining a stable growth environment, so as to keep the plants in a healthy growth state and ensure the plant yield and quality;

[0055] like Figure 4-6As shown, the cultivation chamber 201 includes a hydroponic tube 2011, the end of the hydroponic tube 2011 is clamped with the plugging end cap 202, and a sealing gasket is added at the connection between the hydroponic tube 2011 and the plugging end cap 202 to ensure the sealing degree of the connection.

When the inflowing water is insufficient, the water-blocking baffle 2015 is provided to at least ensure that the water level in the hydroponic tube 2011 is not lower than 1 / 2 of the inner cavity height, so as to ensure that the hydroponic solution can be smoothly added to the planting cup 2013 through the water seepage hole 20130. The arc-shaped water-blocking baffle 2015 does not affect the normal circulation of the hydroponic solution and prevents the high-speed water flow from directly impacting the bottom of the planting cup 2013 extending through the installation groove 2014, effectively preventing the loosening of the installation position of the planting cup 2013 and the installation groove 2014 caused by long-term water flow impact.

[0057] See attached Figure 7-9 As shown, the planting cup 2013 includes an outer cup body 20131 and an upper cup cover 20132, wherein the outer cup body 20131 is configured to be a flat-bottomed flared cup shape that is wide at the top and narrow at the bottom, a water-stop gasket 20133 is fixedly provided at the outer wall of the outer cup body 20131, and a floating plate 20134 is provided inside the outer cup body 20131; the outer cup body 20131 is snap-connected with the upper cup cover 20132, and a planting hole 20135 is longitudinally penetrated at the center of the floating plate 20134, and an upper flared opening 20136 is provided at the top of the upper cup cover 20132; the outer cup body 20131 is fixedly provided with a water-stop gasket 20133, and a floating plate 20134 is provided inside the outer cup body 20131; the outer cup body 20131 is snap-connected with the upper cup cover 20132, and a planting hole 20135 is longitudinally penetrated at the center of the floating plate 20134, and an upper flared opening 20136 is provided at the top of the upper cup cover 20132; A limiting plate 20137 is fixedly provided in an annular shape on the inner wall of the middle part of 131, and a protective bottom piece 20138 is detachably provided at the bottom of the inner cavity of the outer cup body 20131; the annular inner diameter of the limiting plate 20137 is larger than the outer diameter of the protective bottom piece 20138, and the outer diameter of the protective bottom piece 20138 is equal to the inner diameter of the inner cavity at the bottom of the outer cup body 20131, and an arc bottom surface 20139 is fixedly provided at the bottom of the outer cup body 20131, and a plurality of water seepage holes 20130 are arranged in an annular array between the bottom surface of the outer cup body 20131 and the inner cavity of the outer cup body 20131;
