[0002] Isatis can be used as a health vegetable, such as salad or stir-fry. It has a light and slightly bitter taste and has the effects of cooling blood, removing spots, clearing away heat and detoxifying. Outdoor ordinary soil cultivation is once a year. Due to climate constraints, the cultivation cycle is relatively long, the yield is low, and it is difficult to produce continuously. In addition, continuous planting on the same piece of land will cause continuous cropping obstacles, which is not conducive to crop growth. At the same time, the residual pesticides and heavy metals in the soil will also be absorbed by the roots of crops, which is not good for consumers' health after consumption.
[0003] NFT (Nutrient Film Technology) is a hydroponic method that plants roots are planted in a shallow layer of flowing nutrient solution, with part of the root system immersed in the nutrient solution and part of the root system exposed to the air. No soil is needed as root support, and the nutrient solution can provide all the water and nutrients needed for crop growth, while the root system is adequately supplied with oxygen.
[0004] Using NFT to grow Isatis in the greenhouse has a short cultivation cycle, can be produced continuously throughout the year, and has a high yield per unit area; less water and fertilizer are used, no pesticides are used at all, and there is no heavy metal pollution. While obtaining high-yield and high-quality products, the utilization rate of water, fertilizer and land is improved, so it is of great application and research value. For this, our company has launched a project to study the cultivation device suitable for Isatis indigotica nutrient solution cultivation. Utility Model Content

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] Example 1
[0027] like Figure 1-Figure 4 As shown, in this example, a woad NFT cultivation mechanism includes a planting plate 3, a planting slot plate 1, and an impermeable membrane 2. The planting slot plate 1 is in the shape of a through slot, and the planting plate 3 is installed at the slot of the planting slot plate 1. The planting plate 3 is fixed at the slot of the planting slot plate 1, such as by screw fastening, clamping, etc. Preferably, as shown in this example, a sub-mouth 7 is formed at the slot wall of the planting slot plate 1, such as Figure 2 As shown, a notch is formed at the inner side of the top of the notch wall along the extending direction of the notch, the notch is the sub-opening 7, and the two sub-openings form a slot. The size of the planting plate 3 is consistent with the slot so that it can be stuck in the slot during installation, which is convenient for assembly.
[0028] In addition, in order to improve the stability of the planting plate, a support strip 6 can be formed on the bottom wall of the planting slot plate 1, such as a support strip 6 formed in the middle of the bottom of the cavity, with the top of the support strip 6 flush with the bottom wall of the sub-mouth 7, and the support strip 6 abuts against the bottom surface of the planting plate 3 for support. The planting plate can be formed as a single plate body or a double plate body. For the double plate body, Figure 1 , Figure 4 As shown, the left side of the plate body is clamped at the left side opening and the other side is at the support bar, and the right side of the plate body is clamped at the right side opening and the other side is at the support bar and abuts against the left side of the plate body.
[0029] In this example, a gap is reserved between the bottom surface of the planting plate 3 and the bottom wall of the groove cavity of the planting groove plate 1 for the growth of the root system 10 of the woad seedling. A plurality of guide grooves 4 are formed at the bottom wall of the groove cavity of the planting groove plate 1. A planting hole 8 is formed at the corresponding planting plate 3 above the guide groove 4 for the planting of the woad seedling 9. Figure 2 As shown, the guide groove 4 extends from the head end port to the tail end port of the planting groove plate 1, so that the nutrient solution flowing in from the head end port can flow out from the tail end port through the guide groove. For the shaping of the guide groove, for example, a plurality of diverter strips are formed at intervals at the bottom wall of the planting groove plate 1, and the space between adjacent diverter strips or between the diverter strips and the support strips forms the guide groove 4.
[0030] In this example, for the anti-seepage membrane, Figure 1 , Figure 4 As shown, the impermeable membrane 2 is at least partially in the cavity of the planting trough plate 1 and covers the guide groove 4. During planting, the roots of the woad seedlings 9 are above the impermeable membrane 2 or in contact with the impermeable membrane. The roots are covered by the impermeable membrane to prevent the nutrient solution from seeping to the bottom of the planting trough plate when passing through the guide groove.
[0031] In addition, in order to improve the stability of the anti-seepage membrane, such as Figure 1 , Figure 4 As shown, both sides of the anti-seepage membrane 2 extend to the sub-mouth 7. When the planting plate is installed, the planting plate 3 cooperates with the sub-mouth 7 to clamp the sides of the anti-seepage membrane 2. The anti-seepage membrane 2 also covers the support bar 6. When the planting plate is installed, the planting plate cooperates with the support bar to clamp the anti-seepage membrane.
[0032] As for the material, the planting trough plates and planting plates are all made of EPP foam material. The anti-seepage membrane can be directly purchased from the market and formed or cut into shape with the anti-seepage material.
[0033] Example 2
[0034] In this example, a Isatis indigotica NFT cultivation device is disclosed, such as Figure 5As shown, it includes the cultivation mechanism, bed 13, return pipe 15, nutrient solution tank 16, water pump 17, etc. recorded in Example 1, wherein the planting plates 3 can be arranged end to end on the cavity bottom wall of the bed 13 or on the bracket in the bed cavity. A liquid injection pipe is installed at the head end of the bed corresponding to the extension direction of the guide groove, and a water collecting tank 14 is formed at the tail end of the bed corresponding to the extension direction of the guide groove, such as a concave water collecting tank 14 at the cavity bottom wall at the tail end of the bed or a water collecting tank is formed at the peripheral wall at the tail end of the bed, and the water collecting tank 14 is connected to the return pipe 15 outside the bed 13.
[0035] The other end of the return pipe 15 extends into the nutrient solution tank 16. If it is higher than the liquid level of the nutrient solution in the tank, the inlet of the water pump 17 is connected to the nutrient solution tank 16, and the outlet of the water pump 17 is connected to the injection pipe 12. The nutrient solution in the nutrient solution tank 16 is pumped out to the injection pipe 12 through the water pump 17, and injected into the bed cavity through the injection pipe, and then flows into the guide groove from the head end port of the planting groove plate, and then flows out from the tail end port to the water collection tank, and then flows out through the return pipe and returns to the nutrient solution tank. Preferably, the cavity bottom wall of the bed is inclined, such as the connection position of the injection pipe and the bed is at a high position of the cavity bottom wall, and the water collection tank is at a low position of the bed cavity bottom wall. The inclined configuration helps the nutrient solution discharged from the injection pipe to flow spontaneously to the low-position water collection tank.
[0036] When in use, the bed can be placed in a greenhouse, and a hole of woad seedlings is placed in each planting hole so that the roots of the woad seedlings can contact the diversion groove of the nutrient solution. Nutrient solution is injected into the nutrient solution tank, and the water pump is turned on to transport the nutrient solution from the nutrient solution tank to the injection pipe. The nutrient solution flows in from the front end of the bed, flows through the diversion groove to the water collection groove, and flows back to the nutrient solution tank through the return pipe. The nutrient solution forms a circulation between the nutrient solution tank and the bed, and the roots of the woad seedlings absorb water and nutrients from the nutrient solution in the diversion groove for their growth, and the excess nutrient solution flows back to the nutrient solution tank.
[0037] This planting method has the following advantages:
[0038] 1. The water and air in the crop root zone are balanced, the environment is stable, and the root system is well developed.
[0039] 2. Crops grow fast.
[0040] 3. High yield, high quality, no pesticide residues, no heavy metal pollution.
[0041] 4. No soil is required during the cultivation process to avoid continuous cropping obstacles.
[0042] 5. The nutrient solution is recycled, and the utilization rate of water and fertilizer is high.
[0043] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
