The sizes of the water pipe and the rock wool can be adjusted according to the actual size of a mountain construction area, the side length of squares at two ends of the rock wool is kept to be three times of the diameter of the water pipe, the water pipe is positioned in the center of the rock wool, the rock wool at the periphery is thick enough, and the uniform water absorption is ensured; the length of the rock wool can be increased or shortened according to the actual situation. In order to utilize the precipitation to a greater extent, the device can also be matched with a water storage tank and a rain collecting device. The air-dried soil (passing through a 2mm sieve) is piled up into a plane soil layer of 1.5X 0.4m indoors, and the rock wool is buried in the soil, wherein the size of the rock wool block is 15X 100 cm. The top of the rock wool is 10cm away from the soil surface. 4 moisture collection points are arranged on the same side of the rock wool by using the in-situ moisture monitor, a probe is respectively arranged, each point is 10cm apart, and the distance between each point and the side surface of the rock wool is also 10 cm. The first irrigation time is 1 month, 14 days and 15 days: 50, 5L of water is filled, the time for filling water for the second time is 1 month, 15 days and 12 days: 30, 5L of water, and rapidly pouring a large amount of water on the basis that the waterline does not exceed the short pipe opening during water pouring. The moisture diffusion dynamics are shown in fig. 9, and the moisture test results are the volumetric moisture content.
Determination of sampling points: the pecan area embedded with the rock wool is taken as a treatment area, and the pecan area not embedded with the rock wool is taken as a comparison area. The number of the hickory nut in the treatment area is 16-55, and the number of the hickory nut in the comparison area is 1-15. And randomly selecting walnuts in the two areas to carry out long-term tracking test. Finally, soil with the numbers of 9(CK), 14(CK), 17, 20, 25, 30, 31, 50, 51 and 54 and surrounding 10 pecans is selected for data acquisition.
Collecting and sampling a soil sample: according to the actual situation of the mountain land, firstly ensuring that the collection points are on the same plane, secondly enabling the distances from all the points to the trunks of the hickory nuts to be close to be consistent, finally determining three points which take the hickory nuts as the center and are close to the rock wool as the collection points, scraping out impurities on the surface layer of the soil by using a shovel during soil collection, taking the soil with the depth of 10-20cm, mixing the soil of the three collection points, and representing the average situation of the soil around the hickory nuts by using the soil.
Spatial change of soil moisture of forest land: randomly selecting rock wool beside hickory nut for measuring moisture content in 2021 after rainfall is continuously carried out for three days of 4 months 6 days, 4 months 7 days and 4 months 8 days, and selecting the hickory nut with the mark numbers of 25, 26, 50, 54 and 55 and the mountain top. Moisture was measured at 10cm, 20cm, 30cm and 40cm of rockwool using a probe, which was inserted into the soil at each point for five minutes to wait for a reading; the measurement results are shown in fig. 10.
Moisture diffusion result of rockwool: after the water injection at 16:00 pm, no reading was detected in a short period, the water reading was recorded at 9:30 on the next day, and the measurement continued until a steady state was reached at 12:00 on the third day. The highest water content at a position 10cm away from the rock wool can reach 45 percent; because the water is injected once in the middle, the water content of the rock wool is slightly fluctuated, the water content of the rock wool is relatively stable at a position 20cm away from the rock wool, the water content of the rock wool is slowly increased at a position 30cm away from the rock wool, and the water content of the rock wool is less at a position 40cm away from the rock wool and is probably reached mainly through water vapor diffusion. From the above results, it was found that the maximum distance of water diffusion held by rock wool is 30cm, and for a forest land with a line spacing of 60cm, rock wool can be buried in a staggered manner, thereby ensuring water absorption of the plant root system.
It can be seen that rock wool loses its moisture buffering capacity after it is saturated with water. In view of the overall situation, the water seeped from the rock wool is very unevenly diffused under the condition of dry soil, so that the effect of irrigating the water by using the rock wool is possibly inferior to that of irrigating the water by using large water under the extreme drought condition, a large amount of water is required to be avoided at one time in the using process, and the rock wool cannot buffer the water by a large amount of irrigation, so that the water is unevenly diffused, and the irrigation effect is influenced. When the soil drying agent is used, the soil is ensured not to be too dry as far as possible, and the soil which is too dry can absorb a large amount of water to cause that the water cannot be diffused to a hickory root system dense area.
