1. Land preparation and ridge farming
Cucumber planting should choose a weak acidic to neutral sandy loam with loose soil, rich in organic matter, and strong water and fertilizer retention ability, and the most suitable pH value range is 57 to 72。The pH is less than 5At 5 o'clock, the plant may have physiological disorders, resulting in yellowing and death; The pH is higher than 72. It may lead to root burning and salt damage.
The high ridge cultivation method is adopted, the width of the ridge base is 60 cm, the width of the ridge surface is 30 cm, and the ridge height is about 40 cm. Avoid using base fertilizers to encourage roots to penetrate deep into the soil and develop a strong root system.
2. Seed selection and seedling
Choose cucumber varieties with full seeds, disease resistance, strong stress resistance, good commerciality and high yield, such as Jinyou 10, Bonai 3, etc.
Seed Treatment: Soak the seeds in 55 warm water for 10 to 15 minutes, stirring constantly until the water temperature drops to 30, and soak for another 3 to 4 hours. Scrub the seeds to remove mucilage, dry and then germinate. The treated seeds are wrapped in a damp cloth and germinated for 1 to 2 days at 28 to 32 conditions, and 70% of the seeds are germinated before sowing.
3. Transplanting and management
The cucumber seedlings were transplanted when they had two leaves and one heart, and a single row of dense planting was adopted. Set up the drip belt and start watering. Seedlings are planted according to water marks (20 cm), and when they are slightly larger, they are staggered on both sides. After transplanting, the "strong roots and fast trees" are used to irrigate the roots to promote the growth of the root system, shorten the seedling period, promote the growth of the plant, and go to market in advance.
Fourth, seedling management
Temperature control: During the period from sowing to excavation, the temperature is controlled at 28 to 32 during the day and 10 to 18 at night; During the period from excavation to heart breaking, the temperature is controlled at 25 to 30 during the day and 16 to 18 at night; During the period from heart breaking to transplanting, the temperature is controlled at 20 to 25 during the day and 12 to 16 at night.
Water management: Properly control water at the seedling stage to keep the soil moist.
Seedling refining: control water 7 to 10 days before transplanting, increase ventilation and carry out low-temperature seedling refining. The temperature is controlled between 18 and 20 during the day and 8 to 10 at night. When the seedling is 15 cm high, 3 leaves and 1 heart, and the seedling age is about 35 days, it can be transplanted.
5. Fertilization and irrigation
Immediately after transplanting, water the planting is watered, and then rooting agent is applied. When new roots grow in the ground, pour the whole element nutrient solution. About 5 kg per mu at the early flowering stage, about 15 kg per mu at the full fruiting stage, and irrigation once a week for soil cultivation. When the first melon of the plant sits down, start pouring a water, and increase the amount of water appropriately. When the crust is dry, a second tillage is carried out, combined with weeding. After the first watering, keep the soil moist and water flexibly according to the weather and plant conditions.
Sixth, hanging vines
After transplanting, the cucumber begins to hang the vine, and the thicker stem of the hanging vine rope is used to carry out the pan head with the growth of the melon vine, remove the old leaf diseased leaves at the bottom, and improve the light transmittance.
7. Harvesting
Picking begins about 25 to 30 days after transplanting, and the harvest period is about 40 to 60 days. The general yield per mu is 4500 to 5000 kg. When the top of the melon strips is rounded from the tip, the melon strips are fully grown and not overripe, which is the best time to harvest.
