1. Sowing at the right time. In the autumn greenhouse, the sowing date 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 times liquid of the new high-fat film, which can reduce the evaporation of water, prevent the soil layer, suffocate and isolate the source of pests and diseases, and increase the emergence rate.
2. Water and fertilizer management. Watering should be controlled by the two sides to promote the middle, that is, before the meloning period, the middle grounding should be used to improve the ground temperature, so that the wet and dry can be seen; the water should be handed every 7-10 days, 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), which 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.
3. Control Wangguagua. During the flower bud differentiation period, foliar fertilizer should be sprayed in time to convert the vegetative growth of plants into reproductive nutrition, inhibit the main shoots from mad, promote flower bud differentiation, multi-flowering, improve the quality of pollen fertilization, multi-flowering, multi-fruit setting, anti-falling fruit and promote development.
