Experience of soilless cultivation of Hami melon

1. Infrastructure: 1. Sand ridges: dig an inclined trough according to the width of the shed (suitable for running water). Inverted triangle, the width of the top and bottom is about 30 cm, 40 cm deep, 20 or 25 cm away from the bottom of the ditch. Iron net surface covered with plastic mesh (mesh size is appropriate not to leak sand), online ditch wall covered with a layer of linoleum, a layer of plastic sheet separated from the soil, and then filled with sand and the ground, 1.2 meters apart. Change the sand every two years (for fear of repeated cropping). 2. Waterway: at the end of the lower side of the ridge, a row of water trough is vertically dug to communicate with each ridge, and the excess water and fertilizer in the ridge can be reused after being discharged into this trough. Cement trough is used to prevent seepage and suitable for running water, and a storage tank is built on the ground side to communicate with the tank. On the high side of the ridge, there is a main pipe with a diameter of 1.5 or 2 inches, which is connected to the water pump and tied up at the end, and the branch pipe is connected to the ridge with a diameter of 0.5 or 0.8 inch. Two pinhole holes are pierced on the branch pipe beside the seedling, and the end is tied tightly. In order to prevent water from splashing the blade, cover a film on the branch pipe and water it into a half-drop and semi-spray watering after pumping and pressurizing by a small pump.

Second, management: the management method is basically the same as that in the ordinary shed. When the seedling is raised to four leaves and one stamen, it is moved into a sand trough, the plant spacing is 35 cm, and it is watered (with nutrient solution) after planting. Fertilization was carried out by diluting the nutrient solution in the storage tank according to the needs of seedling stage, flowering stage, fruiting stage and mature stage. In the shed, the iron wire is fixed parallel to the ridge along the roof, and the melon seedlings are lifted with plastic blanks to grow upright, and artificial pollination is carried out when the leaves grow to 10 miche. as a result, a good melon is left, the side branches and whiskers are knocked off, and the top is knocked off when the leaves are 27Muth30, and the shed is sterilized once a half month.

The investment of this technology is only about 8 yuan per square meter, which is equivalent to 1/5 of Australia, an advanced agricultural country in the world, and it does not apply chemical fertilizers or pesticides, so it belongs to green food. This technology can also be used in the production of flowers and vegetables.
