2. How is water spinach raised as seedlings?
1. Choose excellent seeds
Water spinach suitable for solar greenhouse cultivation mainly includes green-leaf white-stem, Thai water spinach, white-stem, Nanchang water spinach, Shanghai green-stem, and other varieties. Green-leaf white-stem plants grow vigorously, have more side branches, thick blue-white stems, long ovate dark green leaves, obvious veins, and long blue-white petioles.

The stems and leaves are dark green, with excellent quality, generally yielding 7500 kg per mu.
2. Seed treatment
(1) Chemical seed dressing. Before sowing, dress the seeds with metalaxyl for sterilization.
(2) Seed soaking and germination. The seed coat of water spinach seeds is thick and hard. If sown directly, germination will be slow because of low temperature, and the seeds may even rot. First soak the seeds in warm water at 50°C to 60°C for 30 minutes, then soak them in clean water for 20 to 24 hours. After removing and washing them, place them at about 25°C for germination. During germination, keep them moist and rinse the seeds with clean water once a day. When 50% to 60% of the seeds show white tips, they can be sown.
3. Cultivate strong seedlings
Water spinach can be direct-sown and is also suitable for seedling transplanting. In order to improve the utilization rate of the facility, it is best to carry out seedling transplanting. For solar greenhouse cultivation, the sowing rate per mu is 2 to 2.5 kg. After germination, broadcast sow. After sowing, maintain the temperature at 30°C to 35°C during the day and above 15°C at night. After seedlings emerge in 5 to 6 days, keep it at 25°C to 30°C during the day, and keep it alternating between dry and wet.
4. Land preparation and fertilization
Choose a plot with high terrain, good drainage, and ventilation for planting. Water spinach grows quickly and has strong branching ability, so it needs more fertilizer and water. Sufficient base fertilizer should be applied. Generally, apply 1500 to 2000 kg of decomposed organic fertilizer and 100 kg of plant ash per mu, mix fully with the soil, and make beds 20 cm high and 130 to 150 cm wide.
5. Scientific planting
Water spinach is planted when the seedlings reach 17 to 20 cm tall. Plant 3 rows in a 1-meter-wide bed, with a hole spacing of 35 cm.
