1. Watermelon cultivation technology Watermelon seeds are sterilized, soaked and sprouted after sowing. The substrate plug seedlings are prepared for transplanting when the seedlings are 30 to 35 days old and three leaves are one heart, and the seedlings are refined 1 week before transplanting. In the early stage after planting, the greenhouse is kept warm and moisturized, and the seedlings basically survive and start to grow and ventilate to reduce humidity. As the temperature rises, the amount of ventilation is gradually increased, and the side membrane is completely shaken off during a sunny day in May. Fertilizers are based on "basic fertilizer, supplemented by top dressing." About 10 days after planting, the seedlings are extracted with 0.3% urea solution in combination with watering. Watering should be properly controlled during the flowering and fruit setting period, and the water should be kept adequate during the fruit expansion period. Each time, apply 10 kg of potassium sulfate compound fertilizer per mu combined with irrigation, once every 10 days; stop watering at the later stage of fruit expansion. In the early spring, the first watermelon in the facility is usually harvested about 30 days after pollination, and the second to third crops can be harvested about 20 days after pollination.
2. Zizania cultivation technique Digging seedlings from the reserved field in late April to grow seedlings, divided into small piers with 3 to 4 tiller seedlings, and planted with each branch. Transplanted in late July, planting according to wide and narrow rows, wide row spacing 60 ~ 70 cm, narrow row spacing 40 ~ 50 cm, plant spacing 25 cm, planting about 4000 holes per acre, cutting leaves for planting, leaving seedling height 45 ~ 50 cm. About 20 days after planting, when planting live trees, stand up and apply 8 kg of urea per mu; topdressing fertilizer is applied once a month after planting, and 10 to 15 kg of urea per mu is applied; 1 is applied at the end of September Fertilizer for the second pregnancy, apply 15 kg of urea per mu; winter fertilizer should be supplemented during the prosperous harvest period, usually 10 to 15 kg of imported compound fertilizer per mu. The autumn wild rice is harvested from September to October. In December, the mud was cut off part of the rusty leaves on the ground, the garden was cleaned, and the field was filled with shallow water, and the greenhouse was covered in time. In the early and mid-February of the following year, when the seedling height was 20-30 cm, the seedlings were combined with Yuntian to retain 18-20 strong seedlings per pier. The temperature of the greenhouse is maintained at an average daily temperature of 20°C to 25°C. When the average daily temperature before and after the Qingming period exceeds 15°C, the greenhouse film is removed. Xia Jiao was harvested in early April.
3. The cultivation technology of C. edodes follows the conventional rice seedling cultivation field to make the C. edodes seedling cultivation field. The plant row spacing is 10 cm × 10 cm, to ensure stable planting and slightly exposed bud tips. Pull up the seedlings during planting, remove the old yellow leaves, maintain a 2 to 3 cm water layer in the field, and put the seedling roots into the soil 10 cm. Planting rows are generally 70 cm x 45 cm apart. Within 1 month after planting, keep 3-5 cm of shallow water. Later, as the plants grow, the water level is gradually deepened to 10-15 cm. Fertilizers were applied once each time after the live tree, mid-growth, and 60-80 days after planting. At the beginning of July, combined with cultivating and weeding, fertilizing, stripping the outer and old leaves, leaving 3 to 4 new leaves per plant. In mid-October, the stems and leaves are yellow, and the bulbs are fully mature and harvested.
