Soilless cultivation Hami melon
First, the basic construction: 1, sand ridge: According to the shed width digging one (with energy flow is appropriate) of the trough, inverted triangle, the upper base width of about 30 cm, depth 40 cm, from the bottom of the groove 20 or 25 cm rack shop Iron net, iron net surface shop plastic mesh (mesh size is not imperceptible to sand), online trench wall is covered with a layer of linoleum, a layer of plastic sheeting separated from the soil, and then filled with sand and ground level, ridge distance of 1.2 meters. Change sand for two years (afraid of heavy crops). 2. Waterway: Digging a drainage trough perpendicular to the ridges at the ridge end of the lower side, excess water and fertilizer in the ridge can be discharged into the trough for secondary use, and impregnated with cement to prevent seepage and flow. Side-mounted storage tanks communicate with the sink. The main pipe is set on the side of the ridge with a diameter of 1.5 or 2 inches. It is connected to the pump and the end is tightened. The branch pipe is connected to the ridge with a diameter of 0.5 or 0.8 inches. Two pinholes are drilled on the branch pipe beside the seedling. The hole is tight at the end. In order to prevent the water from spattering the blade, a thin film is placed on the branch pipe, and the water is pumped by a small pump to form a half-drop semi-spraying water. Second, management: Basic management methods are the same as in ordinary sheds. When the seedlings are transplanted into the sand troughs with four leaves and one core, the spacing is 35 centimeters. After the seed is grown, it is watered (with nutrient solution). Fertilization According to the seedling stage, flowering stage, result stage and maturity stage, the nutrient solution is diluted in a storage tank and fertilized. In the shed, iron wires are fixed parallel to the top and ridges. The rakes are lifted upright with plastic blanks. When they grow to 10-13 leaves, they are pollinated artificially. After the result, a good melon is left and the side branches and whiskers are removed. -When the leaves are 30, the top is knocked off, and the shed is sterilized in half a month. This technology only costs about 8 yuan per square meter, which is equivalent to one-fifth of Australia, the world’s advanced agricultural country, and it does not apply chemical fertilizers or pesticides. It is a green food. This technology can also be used for flowers, vegetables and other production.
