How to Grow Winged Beans? Latest Cultivation Techniques and Methods Tutorial
The winged bean is a perennial herbaceous plant in the subfamily Faboideae (Papilionoideae). It is also a fairly well-known vegetable in China, and its tuberous roots, tender pods, and leaves are all edible. The winged bean is rich in protein and fat nutrients, and it is widely cultivated in China. Growing winged beans is actually not very easy and requires a certain level of cultivation skill. So how should winged beans be cultivated? Below, the editor brings you the cultivation techniques for winged beans. Let's take a look!
1. Deep plowing and land preparation
Before sowing, we must first select a good planting plot. Winged beans have few requirements for soil, as long as the soil is not too barren or compacted and is free of pests and diseases. After selecting the planting site, carry out appropriate land preparation. Land preparation is done to improve soil permeability, enhance soil fertility, and promote the growth of winged beans. During land preparation, plow about 30 cm deep, clear the weeds from the plot, and apply sufficient base fertilizer. The base fertilizer is mainly farmyard manure and phosphorus-potassium fertilizer. After deep plowing, disinfect and expose the soil to the sun to eliminate pathogens and insect eggs in the soil and prevent harm to the growth of winged beans.
2. Timely sowing
Winged beans are extremely intolerant of cold, so we should sow after the temperature gradually rises in spring, preferably when the surrounding temperature is above about 20 degrees. One week before sowing, build a seedling bed, then lay plastic film to raise the temperature of the seedling bed, and water appropriately. After the water gradually seeps down, make the field beds and dig the planting holes. When sowing, place 2-3 seeds in each planting hole, then cover with fine soil and plastic film for insulation. Before emergence, keep the temperature of the seedling bed at about 26 degrees to promote seed germination and emergence.

After emergence, enhance the field's permeability and keep the seedling bed temperature at about 23 degrees; the nighttime temperature must not be lower than 15 degrees. If the soil is too dry, water promptly, and as the temperature rises, gradually increase ventilation. When the average temperature stabilizes above 16 degrees, remove the plastic film. When the seedlings have grown 3 true leaves, at about one month, they can be appropriately transplanted. Avoid rainy days when transplanting, and the temperature must not be lower than 15 degrees. Transplant the seedlings with soil attached, control the planting density well, and the main planting method is ridge planting. Ridge planting can not only ensure the healthy growth of winged beans but also raise the soil temperature.
4. Field management
During the seedling stage, winged beans grow very slowly, so regular intertillage and weeding must be done to improve the soil's moisture-holding capacity. Winged beans are relatively sensitive to nitrogen fertilizer, so nitrogen fertilizer should be applied sparingly throughout the entire growth period of winged beans, because the roots of winged beans have a strong nitrogen-fixing ability. Excessive nitrogen fertilizer will cause winged beans to grow excessively and reduce the flowering and pod-setting rate. Winged beans prefer water, so water regularly to keep the soil moist and prevent insufficient soil moisture content from affecting the growth of winged beans. However, water must not be excessive either; do a good job of drainage during rainy days.
The spacing between individual winged bean plants is very large, and the land utilization rate is relatively low, so to avoid wasting land resources, we can intercrop some low-growing vegetables in the vegetable garden, such as rapeseed and others. In addition, winged beans are vining plants, so after entering the vine-running stage, do a good job of trellising and guide the vines onto the trellis in a timely manner.
