1. Sowing seedlings. In mid-January, the seedlings were soaked in the “King Yuan†warm soup and germinated at 30°C for 24 hours after soaking. The germinated seeds were sowed in the water-filled nutrient bowl, one for each pot, 1 cm for the soil cover, and a plastic film on the cover. Before the emergence of seedlings to maintain the temperature at 28 °C ~ 30 °C; after the emergence of the day to maintain the temperature at around 25 °C, 16 °C at night. Seedlings generally do not water, in order to facilitate seedlings, hardening the seedlings a week before planting.
2. Site preparation. During the land preparation, Mushi fully decomposed sheep manure 8 and sprinkled 100 kilograms. Made of 40 cm wide, 50 cm wide, 40 cm wide and 15 cm high, covered with thin film and driped under the membrane. In mid-February, the melon seedlings were planted with 3 leaves and 1 heart, and the plants were planted at a distance of 40 cm and 1850 plants were planted per acre.
Field management
1. Fertilizer management. The planting water was soaked and 5 kg of diammonium phosphate was applied per acre at the time of planting. A small amount of water is poured on the 8 leaves. When the young melon grows to the size of the egg, it is swelled with melon water, and it is 25 kilograms with the water Muse Sprinkle; after 8 to 10 days, it is poured with water, and 5 acres of urea and 10 kilograms are scattered. Muskmelon set to harvest to control watering. After the melons expanded, spray 0.3% potassium dihydrogen phosphate and urea once every other week for a total of 3 to 4 sprays.
2. Temperature and humidity management. The daytime temperature is generally controlled between 25°C and 30°C and at night between 17°C and 20°C. Melons are afraid of high humidity. After the morning, they open up a small breeze and release moisture.
3. Hang vine pruning. Gualou grows to 5-6 leaves when hanging. Timely removal of male flowers, tendrils and lateral vines below 12 knots, retaining 12 to 15 knots of 4 lateral vines, leaving 2 to 3 leaves topping before lateral vines, 25 cultivars topping.
4. pollination to stay melon. At the flowering stage, the pollen is pollinated at 8 to 10 o'clock every morning. During pollination, the newly opened male flower is removed, the petal is removed, the female stigma is gently applied with the stamen, and 2-3 female flower petals are removed for marking. It is also possible to use spirolacyndron, and attention should be paid to the use of concentration. When the young larvae grow to the size of the egg, the melons are selected and the melons with the characteristics of the cultivar are left and the rest are removed. Hang melons to prevent rotten melons.
reward
From the end of April to the beginning of May, when the muskmelon's epidermis turns yellow, the melon hair can be harvested when it fades.
