Latest Water Spinach Planting Methods and Timing Explained in Detail
Water spinach is mainly distributed in the southern regions; in the north it is rarely grown due to climate reasons. It is rich in nutrients and also has the effect of cooling the blood and detoxifying, making it a relatively popular vegetable. Below, Qinnong Web brings you detailed water spinach planting methods and timing, let's take a look.
Planting Time
Water spinach requires an environment with ample sunlight, high temperature and high humidity. Its seeds need a temperature above 15 degrees to sprout, so it is generally planted from April to July. In northern regions, where temperatures are relatively lower, it is generally planted from June to August.
Planting Methods
1. Environmental Requirements
Water spinach is not strict about soil requirements, but it prefers heavy, sticky soil with sufficient fertility. It likes high-temperature and high-humidity environments and can tolerate high temperatures of 35-40 degrees. The optimal growth temperature is 25-30 degrees. It is not tolerant of frost; when frost occurs, the stems and leaves will wither and die. It is not cold-tolerant, and growth stops below 10 degrees. It likes environments with higher air humidity; if the environment is too dry, the fiber content increases, the stems become thick and old, and the eating quality decreases.
2. Sowing
Water spinach seeds have a relatively thick and hard seed coat. If sown directly, germination will be extremely slow, affecting the planting cycle, and if there is prolonged rainy weather, the seeds may rot. Therefore, before sowing, soak the seeds in warm water at 50-60 for 15-30 minutes. During soaking, stir to avoid scalding the seeds, then soak in clean water for one day, then place in a greenhouse environment to promote germination. During germination promotion, rinse once a day until a large area begins to turn white, at which point they can be sown. They can be broadcast sown or drilled in rows, with a seeding rate of about 2 kg per mu. After sowing, cover with a layer of fine soil and water to maintain soil moisture.
3. Field Management
Water spinach has a relatively high demand for fertilizer and water during growth. In addition to applying sufficient base fertilizer at planting time, when it grows to 5 cm it should be watered and fertilized to promote rapid growth. Afterward, it should be watered frequently to keep the soil moist. In addition, after harvesting, fertilizer should also be applied promptly so that it can regrow a second time, with nitrogen fertilizer as the main type. In addition, although water spinach can be planted somewhat densely, if it is too densely planted, it cannot receive sunlight, and may rot.
The above are the planting methods and timing of water spinach brought to you by Qinnong Web. Water spinach is a vegetable that can be harvested repeatedly, but when harvesting, be careful to leave enough 2-3 nodes at the base of the stem to facilitate the sprouting of new buds after harvest, so as to promote high yield.
