The next day, spray the nutrient soil with water again, and then plant it with a layer of fine soil.

Third, seedling management

After sowing the bitter gourd, the greenhouse can be sealed to increase the indoor temperature. The seedlings are inserted into a small arch shed, covered with a film, warmed and moisturized, so that the daytime temperature is protected at 30-35 ° C, and at night it is kept above 15 ° C. When 50% of the seedlings are emerged, the film of the small arch shed is covered in time. After the seedlings are out, the indoor temperature is maintained at 20-25 ° C during the day and at around 10 ° C during the night. See the principle of watering, take the principle of temperature control and water control, and keep the seedlings growing vigorously. In the future, the temperature in the shed will be gradually reduced, and the shed film will be completely opened for a few days before planting to carry out the refining.

Fourth, colonization

Bitter gourd is a vegetable variety that is warm and fertile, so it is necessary to apply enough base fertilizer. Generally speaking, every 667m2, it is necessary to apply 5,000 kilograms of high-quality organic fertilizer and 30 kilograms of diammonium phosphate. After mixing, first make a flat watering, and then dry the soil, then make a width of 80-90 cm. Small sorghum 10-15 cm high, covered with mulch 5-7 days before planting. Two lines per line, the plant spacing is 60 cm, and the line is fixed.

V. Field management

After bitter melon slow seedlings, remember to timely water the seedling water, not too much water. After the bitter gourd plants enter a period of vigorous growth, they should be judged according to the growth of the plants and the weather changes.

The first top dressing is about 7 days after planting, and 10% of the decomposed human excrement or 0.5% compound fertilizer water can be applied. After every 5-7 days, the concentration is gradually increased, and when the flowering result is reached, Human excreta concentration can be increased to about 30%.

During the flowering result, it is necessary to chase 2-3 times of heavy fertilizer to prolong its harvest period. Generally, at the beginning of the flowering period, 25-30 kg of cake fertilizer, 15-20 kg of compound fertilizer and 10 kg of urea are used, and the soil is applied once in combination with the soil; after the first harvest, 20-25 kg of cake fertilizer and 20 kg of compound fertilizer are continued. Once again, every time you harvest 1-2 times, you should apply 30%-40% human excrement or 10-15 kg compound fertilizer. Topdressing depends on the weather and leaf color, and is flexible and discreet.
