The Latest Cultivation Techniques and Methods Tutorial for Nymphoides peltata
Nymphoides peltata generally grows in relatively shallow water and is a wild vegetable widely distributed in China. Wild Nymphoides peltata generally grows beside small streams, beside rivers, in ponds, on shoals, in rice paddies and other areas. With the improvement of people's living standards, the formerly worthless Nymphoides peltata has become very popular. But wild resources are limited after all, so do you know how to cultivate Nymphoides peltata? Let's learn about it together below.
1. Selection and Preparation of the Planting Site
To cultivate Nymphoides peltata, the planting site must be well chosen. If the planting site is improperly selected, then Nymphoides peltata will be very difficult to cultivate successfully. It has relatively high requirements for the growing environment: it needs abundant water resources, soil rich in humus, mud that is neutral or slightly acidic, and a deep soil layer, but with relatively strong air permeability. After choosing the planting site, turn over the land, then carry out appropriate disinfection and soil improvement, add farmyard manure to the soil to increase soil fertility, and then first add about 3 cm of shallow water to soak the field.
2. Propagation Methods
The propagation methods of Nymphoides peltata are divided into sexual reproduction and asexual reproduction. Sexual reproduction refers to seed propagation, while asexual reproduction refers to division propagation and cutting propagation. Seed propagation generally involves pre-germination in March, and sowing in early April when the temperature rises back to about 15 degrees. When sowing, the seeds should be evenly scattered in the field, and then gently patted into the soil. Division propagation is generally carried out in March each year, dividing overly dense plants to form separate plants for planting. Cutting propagation only needs to be carried out when the climatic conditions are relatively good; select the stems and leaves of Nymphoides peltata, keep 3 to 4 nodes, and then insert them into the field.
3. Fertilizer and Water Management
After the Nymphoides peltata seedlings emerge and survive, we need to appropriately deepen the water level according to their growth conditions. The growth of Nymphoides peltata requires sufficient water, so there must be no water shortage. In the early growth stage of Nymphoides peltata, the water level of the planting site only needs to be maintained at about 5 cm; later, the water level should preferably not exceed 30 cm at its deepest, because excessive water will also affect the growth of Nymphoides peltata. During the normal growth process of Nymphoides peltata, we generally apply topdressing after each harvest of Nymphoides peltata, or apply topdressing when the leaves of Nymphoides peltata turn yellow. This is mainly based on nitrogen fertilizer, and it must be used in combination with phosphorus and potassium fertilizers. Sometimes it is enough to directly add manure and urine water or compound fertilizer.
4. Removing Weeds
Because Nymphoides peltata is also a type of wild grass, many weeds usually grow around it, so in order to avoid nutrients being absorbed by other weeds, we must remove the weeds in a timely manner. We can use regular rotation between flooded and dry conditions to reduce weeds, and also improve the quality of Nymphoides peltata to achieve the effect of suppressing weeds with the seedlings and reducing weeds. Finally, we can also use chemical agents for weeding or manually pull the weeds.
Cultivating Nymphoides peltata is relatively simple. As long as the growing environment meets the standards, the yield from an extensive cultivation model is also very considerable. When planting, another point is to be well prepared to prevent aphids, otherwise the impact on the quality of Nymphoides peltata is relatively great.
