The latest four-angled bean planting technique tutorial, with a detailed explanation of cultivation methods
The four-angled bean is also called winged bean, star fruit bean, or four-corner bean. As the name suggests, it has four ridges, similar to a star fruit. It is a kind of bean with somewhat distinctive looks. Its roots, stems, leaves, flowers, pods, and seeds can all be eaten, so it can be said that the whole plant is a treasure, with high economic value. So do you know how to plant it? Let us take a look together below.
1. Deep plowing and land preparation
As for the soil, the four-angled bean is not very strict, but you must make sure the soil is not too barren or compacted, and that there are no pests or diseases. If conditions allow, it is best to choose a plot with fertile soil and a deep soil layer as the planting site. After the planting site is chosen, proper land preparation should be carried out. In order to improve the soil's permeability and fertility, and thereby promote better growth and development of the four-angled bean. The soil needs to be deep-plowed by about 35 cm, then the weeds on the ground should be cleared away, and sufficient base fertilizer should be applied. After deep plowing, disinfection can be carried out to effectively kill pathogens and insect eggs, avoiding disease damage to the growth of the four-angled bean.
2. Timely sowing
The sowing time is best chosen after the temperature warms up in spring, because the four-angled bean has poor cold tolerance, so the surrounding temperature should preferably be around 18 degrees. One week before sowing, the seedbed should be prepared. To increase the seedbed temperature, plastic film should also be laid, and appropriate watering should be carried out. After the water seeps down, make the field beds well and dig the planting holes. When sowing, put 2-4 seeds in each hole. After sowing, cover with a layer of fine soil and film to keep warm and retain moisture. Before emergence, keep the temperature at around 28 degrees, so as to promote the seeds to germinate and emerge as quickly as possible.
3. Transplanting and planting
After emergence, in order to increase field ventilation, the temperature of the seedling bed should preferably be controlled at 25 degrees, and at night it must not be lower than 18 degrees. When the soil is too dry, water in time, and as the temperature gradually rises, slowly increase ventilation. When the temperature stabilizes above 15 degrees, the plastic film can be lifted off. When the seedlings grow 3-4 true leaves, they can be transplanted. Transplanting is best done on a sunny day, at a temperature of around 18 degrees. Transplant with soil to avoid damaging the seedling roots, and at the same time pay attention to transplanting density.
4. Field management
After transplanting, regularly carry out cultivation and weeding. The seedling stage of the four-angled bean grows very slowly. Cultivation and weeding can improve moisture conservation. Nitrogen fertilizer should be applied throughout the entire growth period of the four-angled bean. It is very sensitive to nitrogen fertilizer, and its root system has a strong nitrogen-fixing capacity. Once too much nitrogen fertilizer is applied, it can easily cause excessive vegetative growth, thereby reducing the flowering and pod-setting rate. Also water regularly. The four-angled bean relatively likes moisture, and the soil should be kept moist so as not to affect its growth. However, more water is not always better. Do not allow waterlogging, so as to avoid root rot. On rainy days, drainage work should be done well.
