Method for plan water spinach in win

Water spinach is not strict with soil, but it likes sticky and fertile soil and high temperature and high humidity environment. It can withstand the high temperature of 35-40 degrees. The optimum growth temperature is 25-30℃. It is not cold-tolerant, its stems and leaves will die when it meets frost, and it will stop growing below 10. I like the environment with high air humidity, the environment is too dry, the fiber is increased, the stems are thick and old, and the eating feeling is reduced. Therefore, plastic greenhouses should be used for anti-season cultivation in winter.

Water spinach planting in greenhouse

1. If Ipomoea aquatica is planted in the greenhouse, it is usually sown around 10- 12 every year, and it can be harvested and put on the market after 2-3 months.

2. Because water spinach is a kind of vegetable with fast growth and strong branching ability, it needs enough water and fertilizer so as not to affect its growth.

3. Freezing and heat preservation in greenhouse planting in winter is the key, because the temperature is too low and the air humidity is too high, which is very unfavorable for the growth of spinach, so we should choose the weather with good light and small temperature difference. In cold weather, the temperature in the shed should be kept above 10 degrees Celsius, otherwise it will freeze; When the weather is hot, the temperature in the shed shall not exceed 35 degrees Celsius, and ventilation and dehumidification shall be maintained; If the air humidity is too high in rainy days, the plastic film around the greenhouse should also be uncovered.

4. Generally, after the water spinach is harvested once (it should be harvested in time when it grows to about 35cm), new leaves will grow after a period of time and can be harvested again. Therefore, while ensuring the soil base fertilizer, it must be topdressing on time. After harvesting and topdressing, water in time to keep the soil moist.

5. Water spinach planted in greenhouse is prone to stem rot and damping-off under low temperature and high humidity. The main pests and diseases are red spiders and mites, so we should do a good job of prevention in advance.

Hydroponic cultivation of water spinach

1. Select a container. The hydroponic cultivation of water spinach requires the use of cultivation containers. We can use pots and barrels, waste foam boards as floats, and waste sponges to fix seedlings.

2. soak the seeds. Water spinach seeds should be soaked in warm water for about a day to accelerate germination, because direct seeding will slow germination. The soaked seeds should be fished out, washed with clear water, wrapped in gauze and germinated at room temperature of 25 degrees Celsius.

3. The successfully germinated seeds are evenly scattered in the permeable basin until they emerge.

4. When 4-5 leaves grow after emergence, waste sponge can be fixed in the hole and float on the water.

5. In order for spinach to grow vigorously, nitrogen fertilizer and watering must be added according to the situation after fertilization.

6. Similarly, the fertilizer should be replenished in time after each harvest, and too many knots should not be left after harvest to avoid insufficient nutrient absorption.
