First, nurturing seedlings and seedlings should adopt precise seeding and one seedling. The seedling temperature is more stringent, the optimum germination temperature is controlled at 24-26°C, and after emergence, it is maintained at 23-25°C during the day and 15-18°C at night. The nutrient soil of the seedbed is prepared with decomposed horse dung, furnace ash, etc. to achieve both loose and fertile requirements.
Second, the soil preparation and planting cucumber high yield, large leaves, early fruiting period, but the roots are shallow, weak suction capacity, and therefore require fine-tillage soil preparation before planting, the best soil for planting vegetable greenhouse plots Improved. The specific method is to add 20% of decomposed livestock manure and 30% of sand or furnace ash to the soil in a greenhouse with a depth of 24-30 cm, mix well and apply 50 kg/mu of potassium sulfate compound fertilizer to the tillage layer to reach the soil. Loose and fertile, waterless, conducive to the growth of the root soil environment. The spacing of the cultivars was 35 cm x 70 cm, and the seedlings were watered immediately after planting.
Third, field management
1, temperature management: After planting can be covered with multiple layers and heating and other measures to maintain a higher temperature and humidity within the shed, conducive to slow seedlings. Keep 32-35°C during the day, 17°C at night, cool after a week of incubation, keep it at 30°C during the day and 16-18°C at night.
2. Moisture management: After 5-7 days of planting, slowly pour the seedlings with water once. When watering, it depends on the weather conditions. Generally, it is watered on sunny days. The time is better at 6-8 in the morning (noon of overheated pouring cold water is harmful to the root system. In the afternoon Or watering in the evening, it is easy to cause humidity in the shed, low soil temperature and cause disease. No watering is allowed on rainy days.
3. Illumination and ventilation: The fruit cucumber is resistant to weak light and can obtain high yield under low light conditions. In summer, high temperature and strong light should be covered with a shade net. In the management of greenhouses, the temperature and humidity in the greenhouse should be adjusted by ventilation, and the relative humidity should be controlled at about 60% to prevent the disease caused by excessive humidity.
4, fertilization: combined with watering for fertilization, Shengguai period to take a watery, fat, "eat less and more meals" principle, in the late melon period in the root suction weak, the need to be combined with spray 0.2% -0.3% Potassium dihydrogen phosphate solution is applied extra-root to prevent plant premature decay.
5, harvest: Fruit cucumber grows rapidly, from sowing to commodity melon picking about 45 days, generally do not leave melon root, the timely removal of the young melon, in order to facilitate the growth of plants, because the dragonfly grows stronger, the melon grows quickly , will not affect the harvest time to market. Pre-merchandise melons should also be harvested earlier to increase the previous production.
