1, variety selection.
There are generally two varieties to choose from when planting water spinach. One is willow and the other is bamboo. Willow varieties are green and white, the leaves are willow-like, the leaves are black and soft, and they are very delicious. It grows very fast. It can be planted in summer in the south and harvested in 20 days. An acre of land can harvest about 4000 Jin, which is resistant to waterlogging and heat and has very strong adaptability.
There is also a kind of water spinach, which is a bamboo leaf variety. Its leaves are turquoise, its stems are green and white, and its stems are hollow, thick and firm, and grow upward. It is also resistant to waterlogging and heat and grows rapidly in summer. Water spinach can be densely planted, its buds can be harvested for 3 months, and it tastes delicious.
2. Planting and management.
Water spinach has no requirement for soil, and it can be planted in general soil. It is most suitable to choose the soil with higher terrain and certain water content. Loosen the soil in time in the early stage to increase the surface temperature. But in summer, because of the high temperature, water spinach grows fast and the demand for water is higher.
Water it in time, water it with water. If the weather is dry and the soil is dry, the taste of water spinach will be affected. After watering, you need to fertilize it. Autumn is coming, so we should weed, fertilize, control pests and so on in time.
3. Harvest in time.
When planting water spinach, you must harvest it in time. Generally, water spinach seedlings can be harvested when they grow to 20 cm. Harvest twice, leaving two nodes at the root of the stem for harvesting. After harvesting three times in this way, water spinach can be harvested again, or two nodes can be left at the root of the stem. This is mainly to prevent too many side branches, resulting in slow growth of water spinach.
4. Control pests and diseases.
White rust is most likely to occur when water spinach is planted. In order to avoid this disease, the first method is to implement crop rotation. Before sowing, seeds should be dressed with pesticides. It is also necessary to spray related pesticides at the time of onset, usually once every seven days.
Specific methods: To plant water spinach, we must choose healthy seeds and healthy land. Newly bought seeds are generally soaked in warm water of 50 degrees for 30 minutes, and can only be used for planting when the temperature drops. There is also management, which should be planted in places with high terrain, good drainage and good ventilation. Fertilizer supply is sufficient, and some phosphorus and potassium fertilizers are applied appropriately. Water should also be supplied in sufficient quantities. Once the water spinach is found to be sick, it should be pulled out in time. Pesticides should be sprayed in time at the beginning of the disease, usually once every seven days and controlled three times.
5. Keep the seeds.
After harvesting, you can keep the seeds. Generally, the planted seedlings will be planted upside down in the soil in May, with a spacing of about one meter, and two seedlings will be planted in one pit. You don't need watering and fertilization after inverted planting, but you need to build a shed. Lead the main stem to the top of the shed, and then lead the side branches to the upper shed.
Pay attention to pests when you leave seeds. It usually blooms in August, and the seeds will mature in 10.
