[0034] See also Figure 1-Figure 11 The embodiment of the present invention provides a device for raising seedlings by grafting a high-stem privet, and the device for raising seedlings by grafting a high-stem privet comprises: A base 1 and a cultivation basin 2 arranged on the base 1, wherein a plurality of drainage holes 14 are provided at the bottom of the cultivation basin 2; Precision watering mechanism, the precision watering mechanism includes a lifting ring 5, a support ring 11, a support frame 6 and a watering component. The cultivation basin 2 is provided with a lifting module for placing the support frame 6 and driving the support frame 6 to lift and lower. The lifting ring 5 is rotatably mounted on the support frame 6. The watering component is provided with multiple groups on the support ring 11, and an electric telescopic rod 27 for controlling the working state of the watering component is also provided between the support ring 11 and the lifting ring 5. The support ring 11 is also provided with a control component for driving the watering component to rotate during the watering process; And a humidity sensor 13 for detecting soil moisture, wherein at least one group of humidity sensors 13 is arranged at the bottom of the support ring 11 .

[0035] In an embodiment of the present invention, the device can be placed in an existing culture room, nutrient soil is loaded into the culture pot 2, and a suitable rootstock is planted in the nutrient soil. Generally, a Ligustrum plant with strong growth, developed root system and straight trunk is selected as the rootstock. Its height and thickness are determined according to the desired height of the high pole and the size of the scion. For example, if you want to cultivate a Ligustrum lucidum with a high pole of 2-3 meters, you may choose a rootstock with a height of about 1.5-2 meters and a diameter of 3-5 cm, and then select excellent Ligustrum lucidum branches or buds as the scion. The scion must be healthy, free of diseases and pests, and have a certain number of plump buds. The scion is grafted to the appropriate position of the rootstock, usually at the rootstock's After grafting, on the upper part of the trunk or on the side branches, the lifting ring 5 and the support ring 11 are sleeved on the rootstock, and the support frame 6 is connected to the lifting module. The lifting module can drive the lifting ring 5 and the support ring 11 to move synchronously by driving the support frame 6 to move downward, so as to facilitate the insertion of the watering component and the humidity sensor 13 into the soil around the rootstock, and use the humidity sensor 13 to monitor the soil humidity in real time. If the soil humidity is low, the watering component starts to work for watering. During the watering process, the lifting module can drive the lifting ring 5 and the support ring 11 to move upward, and the lifting ring 5 can adjust the working position of the watering component and the humidity sensor 13 by rotating on the support frame 6. It is convenient to realize uniform wetting of the soil around the rootstock and improve the watering effect. When the humidity monitored by the humidity sensor 13 reaches a predetermined value, the watering component stops working. At the same time, the control component can loosen the soil during the watering process by driving the watering component to rotate on the support ring 11. Loosening the soil can improve the structure of the soil. The soil particle structure after loosening the soil becomes loose, forming a good capillary system, which is conducive to the uniform penetration of water into the entire root zone. Moreover, the loose soil can better retain moisture and reduce the evaporation loss of moisture. For example, in an uncooked substrate, the moisture may be greatly reduced due to evaporation within 1-2 days after watering; and after loosening the soil, the soil will be loosened and the water will be lost. Under the same conditions, moisture can be maintained in the soil for 3-4 days, providing a more lasting water supply for the grafted Ligustrum lucidum seedlings. Loosening the soil can also allow fertilizer to better contact with soil particles, promote the decomposition and release of fertilizer, and at the same time, facilitate the contact and absorption of fertilizer ions by the roots, which is beneficial to improving the quality of seedlings. Compared with the prior art, the present invention avoids the problem that the existing seedling raising method can only rely on experience to perform simple water spraying operations, and cannot accurately control environmental parameters, which easily causes excessive environmental fluctuations, causing the grafted seedlings to suffer from problems such as excessive humidity or excessive drought causing diseases, greatly affecting the success rate of seedling raising and the quality of seedlings.

In the initial state, the blocking block 37 completely blocks the water inlet hole 38. When irrigation is needed, the electric telescopic rod 27 starts to work, so that the lifting ring 5 and the support ring 11 increases, so that the water pipe 19 and the loosening pipe 15 slide relative to each other, and the linkage frame 36 drives the blocking block 37 to move to the side away from the water inlet hole 38, so that a gap appears between the blocking block 37 and the water inlet hole 38, so that the water in the water pipe 19 can enter the loosening pipe 15 through the water inlet hole 38, and the water will enter the water guide cavity 33 through the blocking plate 32.
