Greenhouse vegetable pea early ripening
Seedlings in plastic greenhouses, early-maturing peas and cultivars use vines or semi-traversing varieties, such as Jinsuo No.1, honey beads, and Taiwan No.11. The nursery time is in mid-January and nutritious or nutritious earthworms are used. When sowing, place the nutrient pods or nutritious soil on the seedbeds in order and pour in the bottom water. Then dig 4 to 4 cm in the middle to sow 3 to 4 seeds, sowing 1 seed per hole and then filling it with nutritious soil. In order to maintain the heat and protect the seedlings, the seedbed is covered with plastic film after sowing. After sowing is in the coldest season, pay attention to cold insulation, 10 ~ 18 °C is most suitable for emergence. After emergence, appropriate cooling, to maintain around 10 °C during the day. When it grows to two true leaves, it is appropriate to increase the temperature so as to promote growth, maintain it at 10-15°C during the day and 5°C at night. One week before planting, cool down the seedlings again, no less than 2 °C at night, so that the seedlings adapt to the greenhouse environment after planting, which is conducive to slow seedlings. During the nursery period, watering is generally not used, and no seedlings or cultivators are used. For some droughty seedlings or seedlings, some water may be added. Water can be poured 1 time before planting 12 days to facilitate picking. About 20 days before colonization in early spring, about 2 months early, the shed will be started and the temperature will be increased. After the soil is completely thawed, the soil is turned over one time, and with the ploughing and fertilization, 1/15 hectare (1 mu) of organic fertilizer is applied to 2,500 kg, 30 mg of superphosphate, 50 kg of plant ash, and 15 kg of ammonium nitrate. After the fertilizer and soil are thoroughly mixed, the wolfberry is smooth and fine. Vegetable peas are relatively hardy and can be planted when the minimum temperature in the shed is around 4°C. Colonization should be performed at noon on sunny days without wind, and irrigation can be performed by row spacing first, then seedlings can be planted by plant spacing, and water can be infiltrated to seal the ditch. You can also put the seedlings after the ditch is opened. Early spring, the temperature is low, not too much watering, watering by pressing a hole can also be. To increase the temperature of the greenhouse, small sheds or two-story insulation screens can be placed after planting. Management to promote the slow seedlings, generally closed after planting greenhouses, ventilation and ventilation. When the temperature in the booth exceeds 25°C, it can be ventilated and properly cooled at noon. After easing the seedlings, gradually increase the ventilation, so that the temperature inside the shed is maintained at 15-22°C during the day and 10-15°C at night. If the bottom water is sufficient, it is generally not necessary to apply water to fertilize before planting, and if it is relatively dry, water can be poured once. After easing the seedlings, the cultivators cultivated the soil in time and the seedlings were properly planted until the seedlings were completed before budding, during which the cultivator cultivated soil 2 or 3 times. After budding, the heads of water are poured, and organic manure such as thin manure water and cake fertilizer are applied with the water, so as to sit on a flower and sit in a pod after the watering. Watering should be controlled during flowering to avoid falling flowers. Until the beginning of the flower buds, watering and fertilization will be started to promote the hypertrophy of the pods. Afterwards, fertilize once every 10 to 15 days. In spring greenhouse cultivation, watering is less than that in spring, and fertilization is more necessary. Fertilizers are preferably diluted manure water, cake fertilizer and chemical fertilizers alternately used. Entering the pod stage, the temperature gradually rises, attention should be paid to ventilation, during the day to maintain 15 ~ 20 °C, 12 ~ 15 °C at night, the temperature is too high but will affect the flowering medlar, and easy to make plants premature aging. When the outside temperature exceeds 15°C during the day, the bottom wind can be released. When the minimum night temperature is above 15°C, it can stay up late. When the temperature is higher, the film can be removed, but the ceiling must not be removed to prevent the rapid aging of the pea plants and the quality of the pods.
