Description

Technical Field

[0001] The present invention belongs to the technical field of water supply to the roots of seedlings, and particularly relates to a method for cultivating Trichosanthes kirilowii Maxim. seedlings. Background Art

[0002] During the large-scale cultivation of Trichosanthes kirilowii Maxim. seedlings, drip irrigation technology is usually used.

[0003] Drip irrigation is to use plastic pipes to send water to the roots of crops through orifices or drippers on the water pipes for local irrigation. Drip irrigation has a higher water-saving and yield-increasing effect compared to sprinkler irrigation. It can be applied to fruit trees, vegetables, cash crops, and greenhouse irrigation, and can also be used for field crop irrigation in arid and water-scarce areas. Its disadvantage is that the drippers are prone to scaling and clogging, so strict filtration treatment should be carried out on the water source.

[0004] Dripper aperture: The aperture range of the dripper is generally 0.5 - 2.0 mm, and the specific selection depends on the crop type and soil conditions. For example, the dripper aperture of the patch-type drip irrigation tape is usually 0.5 - 0.7 mm, while the dripper aperture of the labyrinth drip irrigation tape is smaller, usually 0.3 - 0.6 mm.

[0005] However, the patch-type drip irrigation tape is not suitable for drug delivery and for cultivating Trichosanthes kirilowii Maxim. seedlings, because the patch-type drip irrigation tape is generally not buried under the soil and is usually placed on the ground for drip irrigation. For drip irrigation of Trichosanthes kirilowii Maxim. seedlings, it is usually necessary to bury them in the soil; the burial depth of the underground drip irrigation pipe is generally 15 - 30 cm to meet the water demand of the seedlings and reduce evaporation loss.

[0006] The working pressure of the drip irrigation pipe is generally 0.01 - 0.1 MPa. If the water pressure is too high, it may cause the drip irrigation pipe to burst or leak; while if the water pressure is too low, it may cause a large deviation in the dripper flow rate, affecting the irrigation uniformity.

[0007] Currently, for the cultivation of Trichosanthes kirilowii Maxim. seedlings, considering the vulnerability of the seedlings and the water demand for irrigation, generally large-aperture drippers and low water pressure are required. For example, the aperture of the drip irrigation hole is 1.8 - 2 mm, and the water pressure is 0.05 - 0.06 MPa. However, this is likely to cause a problem, that is, for the drip irrigation pipe buried in the soil, some soil may invade the dripper and be blocked when the drip irrigation pipe is not working. Even if the water pressure is used later, it may not be able to flush it open, resulting in the complete blockage of the drip irrigation hole; if drugs are delivered through the drip irrigation pipe, scaling and clogging are likely to occur. This leads to the need to periodically inject pulsed high-pressure water (the water pressure is usually greater than 0.8 MPa) into the drip irrigation pipe to relieve the problem of drip irrigation hole blockage.

[0008] However, this method has several drawbacks. On the one hand, since the drip irrigation pipe network usually covers a large area, a significant amount of water resources will be wasted during backwashing. Secondly, the roots of most plants tend to grow towards water, and a large number of fibrous roots usually accumulate in the area near the drip heads. When high-pressure water is ejected through the unblocked drip holes in combination with small holes, its power is equivalent to a weakened version of a "water jet", which may damage some newly germinated fibrous roots. Finally, since the time required for backwashing is usually long, excessive water flowing out during backwashing often occurs during this period. If not drained in time, it will affect the growth of Trichosanthes kirilowii seedlings. Therefore, drainage work needs to be done well, and it also needs to be carried out on sunny days, which has great limitations.

[0009] Based on this, the present invention is proposed. Summary of the Invention

[0033] Example 1

[0034] 1. Seed treatment: Select Trichosanthes kirilowii seeds that are plump, free from diseases and pests, and have a high germination rate. Soak the Trichosanthes kirilowii seeds in warm water at 40°C for 24 hours, fish them out, drain them, and then sow.

[0035] 2. Sowing time and method: Conduct in March to April. When sowing, dibble at a row spacing of 15 - 20 cm and a hole spacing of 5 - 6 cm, sow 5 - 6 seeds in each hole, cover the soil with 3 - 4 cm, keep the soil moist, and emergence can occur in 15 - 20 days.

[0036] 3. Seedling management: Keep the soil moist, control the temperature between 15 - 25°C, and transplant when the Trichosanthes kirilowii seedlings grow 2 - 3 true leaves.

[0037] 4. Transplanting:

[0038] When the Trichosanthes kirilowii seedlings grow 2 - 3 true leaves, transplant them to the seedling cultivation base, equip the seedling cultivation base with drip irrigation equipment and regularly drip irrigate the Trichosanthes kirilowii seedlings; the row and plant spacing are 15×18 cm or 15×20 cm, cover the soil and trample it firmly, and cover with grass to keep moisture.

[0039] Such as Figure 1 、 2As shown, the drip irrigation device includes a main water pipe 10 and a plurality of drip irrigation pipes 20 arranged according to the ridge direction. The drip irrigation pipes 20 are all connected to the main water pipe 10. The distance between the drip irrigation pipe 20 and the Trichosanthes kirilowii seedlings is 20 - 30 cm, and the burial depth of the drip irrigation pipe 20 is 15 - 23 cm. A high-frequency vibration hose 22 is provided in the center of the drip irrigation pipe 20.

[0040] Embodiment 2

[0041] In Embodiment 1, as Figure 2 、 3 shown, the drip irrigation pipe 20 includes a pipe body 21. A plurality of drip holes 211 are provided on the side wall of the pipe body 21, and the aperture of the drip holes 211 is 1.8 - 2 mm. When the high-frequency vibration hose 22 does not vibrate, the water pressure in the pipe body 21 is 0.05 - 0.06 MPa (i.e., the conventional water pressure).

[0042] One end of the pipe body 21 is provided with an ultrasonic vibrator 30 for driving the high-frequency vibration hose 22. A frustum 40 is provided between the ultrasonic vibrator 30 and the head end of the pipe body 21. The large end of the frustum 40 is fixedly connected to the vibrating end of the ultrasonic vibrator 30, and the small end of the frustum 40 is fixedly connected to the head end of the pipe body 21. The high-frequency vibration hose 22 includes a hose body 22, a stainless steel wire 23 coaxially arranged with the hose body 22, and a plurality of olive-shaped foam aluminum alloy balls 25 sleeved outside the stainless steel wire 23. The tail end of the stainless steel wire 23 is fixedly connected to the small end of the frustum 40, and the head end of the stainless steel wire 23 passes through the side wall of the main water pipe 10 and is fixedly connected to a positioning block 51 outside the main water pipe 10. All the foam aluminum alloy balls 25 are located inside the hose body 22. The head end of the hose body 22 is hermetically connected to the small end of the frustum 40, and the tail end of the hose body 22 is integrally connected with a cover part 221. The inside of the hose body 22 is also filled with a non-Newtonian fluid medium 26.

[0043] A connection hole 11 is provided at the side wall of the main water pipe 10 for communicating with the tail end of the pipe body 21.

[0044] Because drip irrigation pipes are generally made of plastic and have a certain elasticity, their vibration transmission effect is not good. In the present invention, a 3-mm-diameter stainless steel wire has a better transmission effect, and an aluminum wire has a general transmission effect. In addition, a 3-mm-diameter stainless steel wire rope cannot be used because its flexibility is better than that of the stainless steel wire, so the vibration transmission effect is poor.

[0045] Strictly speaking, the cross-section of a rugby ball is not a standard ellipse and does not fully conform to the mathematical definition of a standard ellipse.

[0046] In the present invention, compared with a spherical or ellipsoidal shape, the foam aluminum alloy ball 25 with a rugby ball structure has a larger space remaining for filling the non-Newtonian fluid medium 26, and its two ends are more easily excited under the drive of high-frequency vibration, thereby effectively shortening the operation time.

[0047] The foam aluminum alloy ball 25 is made of a density of 0.8 to 0.9 g / cm 3 Made of foam aluminum alloy.

[0048] A plurality of protrusions 251 are disposed at the lower portion of the foam aluminum alloy ball 25 .

[0049] The non-Newtonian fluid medium 26 is composed of starch, water, ethanol and amyl alcohol in a mass ratio of 24:5:2:1. Its critical shear rate is 134s -1 .

[0050] The stainless steel wire 23 passes through each of the foam aluminum alloy balls 25, and then the stainless steel wire 23 is fixedly connected to the foam aluminum alloy balls 25. The cover portion 221 can be sealed by gluing (such as hot melt adhesive sealing).

[0051] When the ultrasonic vibrator 30 vibrates, it is transmitted to the stainless steel wire 23 and the foam aluminum alloy ball 25 through the frustum body 40, and then is partially weakened by the non-Newtonian fluid medium 26 and the hose body 22 before being transmitted to the water in the tube body 21. The water in the tube body 21 generates a "weakened version" of ultrasonic waves under the disturbance of the high-frequency vibration hose 22, which can impact the drip irrigation hole 211, thereby effectively dredging the soil in the drip irrigation hole 211, and having a good anti-blocking effect. At the same time, the "weakened version" of ultrasonic waves has almost no damage to the roots of Trichosanthes near the tube body 21, and does not affect the cultivation and growth of Trichosanthes seedlings.

[0052] Since the drip irrigation pipe is a low-pressure drip irrigation system, when a drip irrigation pipe is partially blocked, the water pressure in the drip irrigation pipe will automatically increase to maintain the flow rate of other water outlets. Therefore, during drip irrigation, a pressure sensor and a flow sensor can be installed in the drip irrigation pipe. When the blockage coefficient ζ=P / Q (this formula is an empirical formula and does not involve dimensional changes) is greater than or equal to the preset threshold, the ultrasonic vibrator 30 is started, and the high-frequency vibration hose 22 continues to operate until the blockage coefficient ζ is less than the preset threshold; if the high-frequency vibration hose 22 continues to operate for 30 minutes, the control module of the drip irrigation equipment sends an alarm message to the user. Among them, P is the water pressure value in the drip irrigation pipe, and Q is the total flow rate of all drip irrigation holes 211 of the drip irrigation pipe. When a part of the drip irrigation holes 211 is blocked, P will usually rise, Q will drop or remain basically unchanged, and the blockage coefficient ζ will increase significantly.

[0053] 1. Blockage resistance characterization test

[0054] The drip irrigation pipe is buried in the soil to a depth of 23 cm; the soil moisture content is maintained at 65%. A row of blue bricks is stacked on the ground and laid along the axial direction of the drip irrigation pipe 20. The pressure of the blue bricks on the ground is 50 kPa to accelerate the extrusion of the drip irrigation pipe by the soil. When the blockage coefficient ζ ≥ 1 (Q = 20 L / h), the high-frequency vibration hose 22 operates continuously for 30 min; drip irrigation is carried out continuously for 7 days, and the ratio of the blocked drip holes to the total number of drip holes (such as 20) is calculated, and this value is the blockage rate; the judgment criterion for blocked drip holes: the ratio of the actual drip liquid flow rate to the original drip liquid flow rate at the time of factory production is less than 50%, that is, it is judged to be blocked.

[0055] 2. Death coefficient of fibrous roots wrapped around the drip irrigation pipe surface

[0056] Observe the fibrous roots wrapped around the drip irrigation pipe surface and count the total number of dead fibrous roots (blackened, rotten or dried fibrous roots are determined to be dead). The fibrous root death coefficient = total number of dead fibrous roots / length of the drip irrigation pipe.

[0057] 3. Survival rate of planted Dendrobium huoshanense seedlings

[0058] Artificial seeds of Dendrobium huoshanense: Artificial seeds of Dendrobium huoshanense with axillary buds, protocorms, and adventitious buds as propagules have a germination rate of 65% - 90%, but the survival rate of seedlings is extremely low, usually 15% - 20%.

[0059] In the present invention, Dendrobium huoshanense seedlings are interplanted with Trichosanthes kirilowii Maxim. seedlings after transplantation. One month after transplantation, observe and measure the survival rates of Trichosanthes kirilowii Maxim. seedlings and Dendrobium huoshanense seedlings. When interplanting, the ultrasonic oscillator 30 operates ultrasonically for 30 min every day, and the corresponding ultrasonic frequency is 117 kHz; if the blockage coefficient ζ is greater than or equal to the preset threshold, start the ultrasonic oscillator 30 and operate ultrasonically for 30 min at an ultrasonic frequency of 117 kHz.

[0060] Example 3

[0061] The difference between this example and Example 2 is only that the foam aluminum alloy balls 25 and the hose body 22 are not sleeved, and the stainless steel wire 23 is directly in contact with the water in the pipe body 21, and the rest are the same.

[0062] In this example, it is equivalent to directly applying the unweakened ultrasonic vibration to the water in the pipe body 21.

[0063] Example 4

[0064] The difference between this example and Example 2 is only that the non-Newtonian fluid medium 26 used in this example is water, and the rest are the same.

[0065] Example 5

[0066] The difference between this example and Example 2 is only that in this example, the non-Newtonian fluid medium 26 is starch and water (mass ratio 3:1), and the rest are the same.

[0067] Example 6

[0068] The difference between this example and Example 2 is only that in this example, the non-Newtonian fluid medium 26 is toothpaste (Zhonghua brand, classic series), and the rest are the same.

[0069] Example 7

[0070] The difference between this example and Example 2 is only that in this example, the non-Newtonian fluid medium 26 is composed of starch, water, and ethanol mixed in a mass ratio of 24:5:3, and the rest are the same.

[0071] Example 8

[0072] The difference between this example and Example 2 is only that in this example, the non-Newtonian fluid medium 26 is composed of starch, water, and pentanol mixed in a mass ratio of 24:5:3, and the rest are the same.

[0073] Example 9

[0074] The difference between this example and Example 2 is only that in this example, the foam aluminum alloy ball 25 is an aluminum alloy ball, and the rest are the same.

[0075] Example 10

[0076] The difference between this example and Example 2 is only that in this example, the stainless steel wire is replaced with an aluminum wire, and the rest are the same.

[0077] Example 11

[0078] The difference between this example and Example 2 is only that in this example, the stainless steel wire rope is replaced with a stainless steel wire, and the rest are the same.

[0079] The test results of Examples 2 to 11 are shown in Table 1:

[0080] Table 1

[0081]

[0082] It can be seen from Table 1 that if the high-frequency vibration hose 22 is not used to weaken the ultrasonic vibration to a certain extent, it will directly affect the growth of the fibrous roots wrapped on the surface of the drip irrigation pipe, and even cause the death of some fibrous roots.

[0083] The medium in the pipe body 21 is preferably a non-Newtonian fluid medium 26. Pentanol is slightly soluble in water but can be miscible with organic solvents such as ethanol and ether. Therefore, a system composed of starch, water, ethanol, and pentanol is more suitable for weakening ultrasonic vibration, and the added pentanol will significantly affect the survival rate of Dendrobium huoshanense seedlings.

[0084] Example 12

[0085] Based on Example 2, for the change in the ultrasonic frequency of the ultrasonic oscillator 30, the corresponding curve of the blockage rate change can be seen in Figure 4 ; It can be seen from Figure 4 that when the ultrasonic frequency of the ultrasonic oscillator 30 is 31 kHz, 52 kHz, 69 kHz, 117 kHz or 205 kHz, the blockage rate is less than or equal to 5%, which can meet the usage requirements.

[0086] However, in the test of "the death coefficient of fibrous roots wrapped on the surface of the drip irrigation pipe", it was found that when the ultrasonic frequencies were 31 kHz, 117 kHz and 205 kHz, the death coefficient of fibrous roots was less than or equal to 2 per dm. In the test of "the survival rate of the seedlings of Dendrobium huoshanense planted in intercropping", it was found that only when the ultrasonic frequency was 117 kHz, the survival rate of the seedlings of Dendrobium huoshanense exceeded 40%; even when the ultrasonic frequency was 31 kHz, the survival rate of the seedlings of Dendrobium huoshanense was only 26%.

[0087] Example 13

[0088] When cultivating the seedlings of Trichosanthes kirilowii, if Epimedium brevicornum is planted in intercropping, it is found that the survival rate of Epimedium brevicornum still remains at 21-33%, which is not much different from the survival rate (18-30%) when the high-frequency vibration hose 22 is not activated.

[0089] Example 14

[0090] To ensure tightening, a fastener 50 for tightening and sealing the positioning block 51 is further provided on the outer side of the main water pipe 10. First, the wedge-shaped plug inside the fastener 50 is inserted into the gap between the positioning block 51 and the main water pipe 10 to tighten, and finally, it is sealed by applying glue.

[0091] Example 15

[0092] For the convenience of installation, a lead pipe section 41 inserted into the head end of the pipe body 21 is integrally connected to the small end of the frustum 40.

[0093] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
