1. Sowing at the right time. The cucumber can be transplanted in the autumn greenhouse, and it can also be broadcast live. The variety can be selected from Zhongnong 12 and Zhongnong 16 and so on. The sowing period should be properly selected. The premature seedling stage is hot and rainy, and the disease is serious; the temperature in the late growth period is difficult to guarantee, resulting in a decrease in yield. After the whole planting, the soil surface is sprayed with 600-800 times of new high-fat film, which can protect the water-proof evaporation, sun-proof and drought-resistant, heat-preserving anti-freezing, anti-soil layering, suffocation and isolation of pests and diseases, and increase the emergence rate.
2. Planting density. After the greenhouse is extended in autumn, the cucumber should be properly planted. The planting density should be determined according to the variety and the soil strength. Generally, 400 plants per acre are suitable.
3. Water and fertilizer management. Watering should be controlled by the two sides to promote the middle, that is, before the meloning period, the middle temperature is mainly used to improve the ground temperature, so that we can see the wet and dry; the water is given every 7-10 days in the melon period, and the water should be picked every time. Before proceeding, to control the madness; after the top melon is finished, control the watering and promote the new root. When the melon is inflated, it should be watered in time. In the later stage, the temperature is lowered, the growth of cucumber is slowed down, and the requirement for fertilizer and water is lowered. In order to reduce the temperature inside the shed, watering should be strictly controlled, and watering is generally performed once every 10-15 days. Under the premise of ensuring the supply of soil nitrogen, appropriate application of phosphorus and potassium fertilizer. The base fertilizer is generally combined with the preparation of the ground, applying 5000 kg of farmyard manure and 30-50 kg of compound fertilizer per mu. Fertilization should be combined with the use of photosynthetic nutrient film fertilizer (light fertilizer) to enhance the photosynthesis capacity nutrients and chlorophyll, advanced environmentally friendly plants to increase fertilizer, increase production, color enhancement, leaf hypertrophy, dry stem strong compound membrane. It can help plants absorb a lot of light fertilizer, light energy, light, compatible with conventional fertilizers and nutrients to supply plant growth and development to the limit. One-year benefits for one application. Topdressing is in liquid form and is fertilized with water. Before flowering, the young melon period, the swelling period sprays the strong melon timidine, can make the cucurbit thickening, strengthen the nutrient directional transport, promote the rapid development of the melon body, the melon shape is beautiful, the juice is delicious; the growth cycle is not falling, not Drop melon, no cracked melon, no deformed melon.
4. Temperature management. The suitable temperature for cucumber production and development is 25 degrees -30 degrees. When the temperature exceeds 30 degrees, the plant grows faster and is prone to madness. Therefore, the early temperature is higher, it is necessary to pay attention to temperature control, the greenhouse temperature should be controlled at 25-30 degrees during the day, not more than 30 degrees, and the night temperature should be maintained at about 18 degrees to reduce the respiration and increase the accumulation of dry matter. In the later period, the temperature dropped sharply. The management was mainly based on cold insulation. At the same time, attention was paid to ventilation and ventilation to prevent the temperature from being too high. The disease spread, and the night temperature was lower than 13 degrees. Pay attention to the closed greenhouse insulation.
5 Baogua. After cucumber cucumbers, the vegetative growth of the plants is controlled. Therefore, foliar fertilizer should be sprayed to transform the vegetative growth of plants into reproductive nutrients, inhibit the main shoots from mad, promote flower bud differentiation, multi-flowering, improve pollen fertilization quality, more flowering, more fruit, anti-falling fruit and promote development.
