[Previous technology] μ 5 plants use the roots to absorb water and nutrients, and obtain retention and growth. Plants grown in soil are fertilized or equivalent to provide nutrients for plant growth through the soil. And retention; therefore, the nature of the soil is an important factor affecting plant growth. g. The properties of soils can be divided into physical properties of water retention and air supply, chemical properties of nutrients and ion exchange, and biological properties of biological effects according to functional analysis. Among them, chemical and biological properties can be achieved by irrigation, fertilization, soil modification, and even rotation or fallow. However, the improvement of soil physical properties often has many restrictions and cannot be taken into account at the same time. For example, sandy soil The soil has a large porosity, so the water retention capacity and fertility are poor, and due to the good air permeability, the organic matter decomposes quickly and the fertility is low, but the drainage is good, which makes the roots of the plant have better stretchability, and at the same time, the fertilizer and fertilizer effect good. The dry soil loach has small porosity and plasticity, so it has good water retention and fertility retention, and strong cation exchange capacity between particles, but poor drainage and air permeability. If you choose 20 loam with a porosity between sand and dry soil, because its physical properties are between sand and dry soil, all properties are also located between the advantages and disadvantages of sand and clay. Accept soil for plant cultivation. However, 'Although loam is selected for the balance of good and bad, the long-term continuous irrigation operation will still change the soil properties; because of moisture 7 200417310 玖, invention description (2) In the soil, gravity water, Capillary water, absorbing water, and crystal water exist in four kinds of centers, and only capillary water is the main absorption type of plants. In order to make the amount of capillary water in the soil meet the needs of plants, no matter whether it is surface irrigation, spray irrigation, underground irrigation, or drip irrigation, etc., 5 oz will saturate the soil moisture content and cause soil air content. It is greatly reduced. After the soil is properly drained, the air can gradually infiltrate through the soil surface and increase the air content in the soil. However, if the irrigation is continued for a long time, it will easily cause the microstructure of the soil to collapse, which will gradually reduce the soil porosity, affect the drainage and air permeability of the soil, and then reduce the soil air capacity 10 and water capacity. Decreasing the amount of air in the soil will make the supply of oxygen and nitrogen insufficient, which will not only hinder plant roots from breathing and stretching, but will also be harmful to the activities of microorganisms in the soil, slow down the decomposition of organic nutrients and the progress of nitrification, and then reduce soil fertility. Hinder the growth of plants. The reduction of water capacity will make the soil 15 soils insufficient in water retention capacity, forcing the number of irrigations to increase to meet the water requirements of the plants, which not only greatly increases the cost, but also a serious waste of water resources. [Summary of the Invention] Therefore, an object of the present invention is to provide an air-water alternate cultivation method and system for increasing air content in soil. 2〇 = Ming ^ Another-the purpose is to provide-a method and system for simultaneously increasing soil moisture content and gas-water alternate cultivation methods containing aeration. Another object of the present invention is to provide a gas-water alternate cultivation method and system for directly improving soil physical, chemical and biological properties. 8 200417310 玟, description of the invention (3) Therefore, the gas-water alternate cultivation method of the present invention It is used for cultivating plants grown in soil, and the cultivation method includes the following steps: a) transferring liquid to the soil through the underground pipeline; b) removing liquid from the underground pipeline; and 5 c) transferring gas from the underground pipeline Transported into the soil. The gas-water alternate cultivation system designed according to the above cultivation method includes an input device having an input tube, a circulation device having at least one circulation tube connected to the input tube and buried in the soil, and An output device of an output tube connected to the circulation tube, and a plurality of tail tubes connected to the 10 circulation tube, respectively. The input device further has a water inlet valve in communication with the input pipe, and an air pump in communication with the input pipe. The output device further has a pump connected to the output pipe. The circulation pipe has two mutually-distant nozzles, one of which is in communication with the input pipe, and the other 15 of which is in communication with the output pipe. Each of the tail pipes is buried in the soil higher than the circulation pipe and has a pipe wall and a plurality of perforations formed on the pipe wall. By controlling the water inlet valve and the air pump, liquids and gases can be delivered to the soil from the tail pipes at different times.

The pumped fruit 62 is recovered into the blending, and also $. In this embodiment, when the suction pump 62 is started, the water inlet valve 42 20 is closed. At this time, since the check valve 431 can automatically take in air, the residual liquid can be smoothly discharged from the underground pipeline. Step 104 'transports the gas into the soil 91 from the underground pipeline. In this embodiment, the air is directly extracted through the air inlet 43 of the air blower 43 and the air is delivered to the soil 91 at a pressure of about 1 atmosphere. 13 200417310 发明, Description of the invention (8), long: 幵The content of nitrogen and other elements in the soil 91 provides nutrients required for the growth of microorganisms in the soil 91 and elements required for nitrogen fixation. The pressure of pressing the gas into the soil 91 is not limited to the above. Of course, the pressure of 1 atmosphere pressure to 1.5 atmosphere pressure can be sent into the soil 91 through the underground pipeline 5. In addition, if necessary, the A specific gas is input to the air inlet 430 of the inflator 43. In step 106, the above steps 100 to 104 are repeated. Continuously inject liquid and gas into soil towel 91, so that the roots of plant 92 exist in an environment full of sufficient moisture, nutrients, and air, while maintaining the temperature of soil 10 and 91, and maintaining the looseness of soil 91. For plant 92 roots to stretch. In the above-mentioned steps, since the liquid and gas of the 92 roots of the plant are directly transported into the soil through an underground pipeline, compared with the traditional method such as 15 20 to allow the air to naturally penetrate the soil 91 into the soil 91 after being drained, At the same time, the efficiency and total amount of air entering the soil can be improved, and the fine structure of the soil can be avoided during drainage. The soil porosity and sparseness of the soil are maintained at 9 °, and it is used as the input line below the 92 roots of the plant, making it adjacent. The roots of the plant 92, soil k9, ☆, and w8, can reduce the loss of gravity from the fire sword to the support, and then control the physical properties of soil 壌 91. Firstly, the liquid and body 11 required for the first 2 roots of the plant 92 are directly provided by the underground ground, so that only the surface of the roots of the neighboring plant 92 is exposed to the air. ~ The master is better than the soil surface ^ 'Therefore Although the film cloth M in this embodiment avoids soil dust and 99 / ^ cloth 8b, it can still enjoy the advantages of 7 minutes of water loss, evaporation loss, and pest control, etc. 14 200417310 发明, invention description (9) 5 10 15 described above, The gas-water alternate cultivation method and the system of the present invention directly transport gas into the human soil moisture by the underground pipeline, effectively increasing the air content in the soil moisture 91 'to directly improve and maintain the physical properties of soil M, and because The liquid and gas are alternately sent into the soil 91 alternately, and the water content and gas content of the soil 91 can be increased at the same time, and the object of the present invention is indeed achieved. At the same time, 'there is no need to worry about the air quality of the 92 roots of the neighboring plants; therefore, "the film cloth 81 performs 92 leaves of the plant = and uses the spray device 8 to control the temperature and humidity of the planting area, and spray water to the soil. And the application of leaf fertilizer, and at the same time can provide sufficient air for the roots of plants 92 and a good growth environment. It should be particularly noted here that, because the waterproof membrane cloth 81 can effectively isolate the environment inside the soil cricket 91 and the outside of the plant 92 where the stems and leaves of the plant 92 are located, the temperature and humidity control of the ㈣ spray device 8 can more effectively Without affecting the root environment of the plant 92, adjust the environment around the stems and leaves of the plant 92 to make a drastic change between relative humidity and 50% to prevent the breeding of most diseases and insect pests. However, the above is only one of the preferred embodiments of the present invention. When the scope of implementation of the present invention cannot be limited by this, that is, simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the invention specification Fu, 20 should still fall within the scope of the invention patent.
