Cucumber seedlings in the greenhouse can be transplanted to encourage the development of more short, fibrous roots. This helps improve nutrient absorption and overall plant health. For optimal results, select varieties such as Changchun Mizhi, Zhongnong 5, Jin Za 4, Zaofeng, and Xiangcuo 2, which are known for their early maturity and strong growth.
To prepare the growing medium, mix non-meat roasted sunscreen soil, roasted pig manure slurry, carbonized rice husks, and a proper amount of nitrogen fertilizer. The ideal ratio is one-third garden soil, one-third pig manure slag, and one-third carbonized chaff for the main seedbed. For the sub-beds, use two parts garden soil, one part pig manure residue, and one part carbonized chaff. Add 0.5 kg of urea per cubic meter of soil mixture and blend thoroughly. To sterilize the soil, mix 200–300 ml (0.2–0.3 kg) of 40% formalin with 25–30 kg of water, then spray it over 1,000 kg of culture soil. After mixing, cover the bed with plastic for 5–7 days to ensure effective disinfection.
For early maturing cucumber seedlings, electric heating beds are recommended. Use 80 watts per square meter for the main seedbed and 60 watts per square meter for the sub-bed. A standard bed size is 10 meters by 1 meter. Choose the DV20810 model for the main seedbed and the DV20608 model for the sub-bed. Wire spacing should be 10 cm for the main bed and 12.5 cm for the sub-bed. Dig a trench 5–6 cm deep (7–8 cm for the sub-bed), lay down an insulating layer, insert small bamboo sticks at both ends, and run the wires back and forth. Cover with good quality culture soil, about 2 cm thick.
Sow seeds in mid-to-late January, using approximately 250 grams per acre. For each 10-meter by 1-meter bed, sow 0.6 kg of seeds. Before sowing, soak the seeds for disinfection. One method is to first soak them in room temperature water for 1 hour, then in 55°C water for 10–15 minutes, and finally in 30°C warm water for 2–3 hours. Alternatively, soak in warm water for 2–3 hours, then dip in a 1:100 formalin solution for 30 minutes, followed by thorough rinsing. Germinate the seeds at 28–30°C. When the seeds begin to sprout and the white tip is visible, lower the temperature by 1–2°C for 4–5 hours, then gradually raise it back to 28–30°C until 70% of the seeds have germinated.
When planting, water the beds thoroughly, loosen the soil, sow evenly, cover with a thin layer of soil, press the soil gently, and place a tunnel over the bed.
After sowing, maintain a moist bed and keep temperatures between 23–25°C during the early stages. Once the cotyledons appear, adjust daytime temperatures to 16–18°C and nighttime temperatures to 12–14°C. Limit watering and allow as much sunlight as possible. During this phase, avoid lifting the covering or ventilating the bed.
About 10 days after sowing, transplant the seedlings when they have two true leaves. Space them 8–10 cm apart on a wet seedbed. Carefully lift the seedlings without damaging the stems, protect the cotyledons, and ensure the roots and neck are well covered. Water the roots immediately after transplanting.
During the slow-growing period, maintain a bed temperature of 18–20°C and keep the surface moist but not overly wet. In the vigorous growth phase, lower the temperature to 16–18°C during the day, ensuring it doesn’t drop below 12°C at night. Maximize ventilation and light exposure, and apply top-dressing with a 0.1–0.2% urea solution when the plants have 3–4 leaves. Keep the soil surface semi-dry. Spray ethephon at 150–200 mg/L during the 2–4 leaf stage to increase female flower production. Loosen the soil when the top layer dries.
Four to five days before transplanting, implement hardening-off techniques such as gradual cooling, reduced watering, and increased ventilation to strengthen the seedlings.
Anti Bird Net
Anti Bird Net
Anti-bird net is a kind of polyethylene, high-density polyethylene, polypropylene and nylon which are added with anti-aging and anti-ultraviolet chemical additives. It is a kind of plastic woven mesh and anti bird net has the advantages of high tensile strength, heat resistance, water resistance, corrosion resistance, aging resistance, non-toxic and tasteless, and easy disposal of waste. It can kill common pests such as flies and mosquitoes. The conventional use of the collection is light, and the correct storage life can reach 3-5 years.
Bird-proof net cover cultivation is a new environmentally-friendly agricultural technology that increases production and practicality. It builds artificial isolation barriers on the scaffolding, rejects birds outside the net, cuts off bird breeding routes, and effectively controls various types of birds. Spread and prevent the spread of viral diseases. And it has the functions of light transmission and moderate shading to create favorable conditions for crop growth.
The bird-proof net also has the function of resisting natural disasters such as storm erosion and hail attack.
Beyond garden, the anti bird net also be used in airport, building, residential houses, etc.
