Selection of land: white melon seeds are afraid of drought, thin and resistant to ridges. Choose a well-drained land on the hillside. There should be no residual pesticides in the soil. For example, it is not possible to grow white melon seeds within 4 years of Pusset, 3 years of methylsulfuron, and 2 years of fomesafen. Otherwise, there will be phytotoxicity. Tillage and ridge Tillage: more than 25 cm deep and loose, pine ploughs more than 25 cm deep, shallow 17-20 cm. Should not turn the floor. Repeat 2 times, lightly 1-2 times, to declare, level, broken. Rigging: 65, 70 cm in small ridges, 20 cm in ridge height (calculated at the base of furrows); 90, 110 cm in large ridges, 15-17 cm in ridge height, and flat ridges, consistent in height. Rigging should be uniform, straight and flat. The original ridge card: Former bean pods, land number cleaned up, ridge-shaped intact, early spring 3-4 centimeters after the pods to be card species. The ridge-shaped poor ridge repression card broadcast. Variety selection and seed coating According to the accumulated temperature selection of varieties: 4-5 accumulate temperature zone, should use 95-110 days, effective activity accumulated temperature in the 1900-2100 degree species. Based on physiochemical trait selection: white. Large board, board width 12 mm or more. Contains high protein and fat. Disease-free, frozen plate, yellow plate, hemp plate, odd-type plate varieties. According to the choice of vitality: moisture content below 13%, germination rate of 85% or more. Selection: artificial hand selection, the cleaning rate is 100%, no insects, damage, small particles, remove the surface protective film. Seed coating: Select root rot and blight. Underground pest agent seed coating agent. The seeds are sown on the day of sowing and can be sown after air drying. Fertilizer Fertilizer amount: white melon seeds need less fertilizer, soil organic matter content of more than 5% mu fertilizer ratio: nitrogen 3 kg, phosphorus 7 kg, potassium 3 kg, organic matter content below 5% mu fertilizer ratio: nitrogen 4 kg, phosphorus 9 kg, potassium 3 kg. If Mushi organic fertilizer 2 tons, the amount of chemical fertilizers will be halved. Fertilization method: deep layer fertilizer under the seed layer, mechanical ridging and clip fertilizer, or all the layers of fertilizer once in the sowing, deep planting, planting 3-8 cm. Can not grow mixed fertilizer or seed fertilizer with the bed. Artificial hole sowing first deep planting of chemical fertilizers, replanting after sowing. sowing Sowing time: When the sliding temperature is stable within 5 days, the seeding begins with 8 degrees. In the southern region after May 10, the northern region will be sown after May 15. Seeding method: air-suction fine seeder drill, ridge distance of 65,70 cm, the next distance is 30, 35 cm, and the seedling protection distance is 60-70 cm. Manual, mechanical hole sowing, point distance 60-70 cm, 2-3 seeds per hole. Hectare seedlings are 2.0-2.3 million. After sowing, 3-4 cm deep, and timely suppression after sowing. Field management Weeding: for the first time after hatching, weeds are used for artificial grasses, and weeds are used for thinning; after 3-4 leaves are unfolded, artificially weed the grass for the second time; third weeds are 30-40 cm in length; Manually pull the grass 1-2 times after the ridge. Intertillage: The first time the ridges were deep and loose, with a depth of 25 cm. The second cultivator in the 3-4 leaf stage, and the third cultivator soil when the vine grows 20-30 cm. Foliar fertilization: mechanical or artificial foliar spraying fertilizer, the first leaf spray in the 3-4 leaf stage, according to different fertilizer requirements, the water volume does not exceed 100 kg/ha. For the second time, 40 centimeters were used for fertilization. Units with aeronautical conditions can fertilize for the third time during flowering or fruiting. Disease prevention: seedling disease control by seed coating agent, growth phase disease mainly virus disease, powdery mildew, gray mold, downy mildew, disease, etc., with chlorothalonil, carbendazim, chlorpromazine, antiviral drugs and other agents Prevention. Most of the period of the disease is in the late growth period. Appropriate chemical control is applied to different diseases, and the prevention and treatment time should be at the initial stage of various diseases. It is best to control 2-3 times. Can be combined with foliar fertilization. Gauze Balls,Cotton Gauze Balls,Absorbent Gauze Balls,Disposible Gauze Ball Zhende Medical Co.,Ltd , https://www.zdmedicalproduct.com
