Winged Bean is a new type of special vegetable with high nutrition. It is rich in protein and various nutrients. It is rare on the market. It can only be purchased in Hainan. Its market price is high and there is a very good planting prospect. How to grow it? What? The following small series will introduce in detail the main cultivation techniques of Long Edge Giant.

Long-edge giant breed characteristics

The long-breasted giant tyrant is late-maturing, with a total growth period of about 270 days. It takes 60 to 70 days to sow it, and the growth cycle is long. The fruit pod is long and the color is tender green. The seeds are nearly spherical, dark brown and shiny. The number of seeds per pod is 10 to 16 and the weight of seeds is 370 g. The yield per pod of 667 m2 is about 3 078 kg. The resistance to field blight, root rot, fruit rot and viral diseases in the field is comparable to that of Sanya, but it is less harmful.

Main cultivation technique

1 Site selection of Winged Beans is a leguminous root crop. It is advisable to choose fertile, loose, water-permeable and neutral loam. Before sowing, generally 1 000 to 1 500 kg of decomposed organic fertilizer, 500 kg of plant ash or fire ash and 50 kg of phosphate fertilizer are used as base fertilizer, and then ditch is used as a base. The required width is 50-60 cm and the height is 20-25. Cm, the sulcus is 25 to 30 cm wide.

2 Sowing according to the temperature required for the growth of the ridged bean, as long as the local temperature is stable at around 25 °C, it can be sown. Seeds must be sterilized before sowing, and soaked in warm soup. The planting distance is 90 cm, the plant spacing is 60 cm, and 2 to 3 seeds are planted at each hole. After sowing, the wood ash is covered and the soil is 3 to 4 cm thick. If the seedlings are transplanted, the seedlings can be transplanted to the field when they grow 4 to 6 true leaves.

3 Field management

3.1 After 7 days of sowing seedlings, when the seedlings began to be unearthed, the seedlings were planted when the seedlings were 7 to 8 leaves long, and the weak seedlings, diseased insects and malformed seedlings were removed in time, and 1 to 2 strains were selected for each well to grow robust and pest-free. Healthy seedlings, 1,500 to 2,000 plants per 667 m2.

3.2 cultivating and cultivating soil, pruning vines after the emergence of vines for 30 to 40 days (days), when starting to vine, it is necessary to use bamboo and wood to form a "person" frame in time, and cultivating 1 or 2 times before vines, vines After cultivating for 1 or 2 times, the soil should be cultivated after the leaves are sealed, and the soil is 15-20 cm thick. In the flowering and pod-forming stage, multiple picking should be carried out to promote branching and promote the results. At the same time, the densely divided second and third branches and over-expanded branches and leaves should be removed in time to save nutrients and increase the fruit setting rate.

3.3 Fertilizer and water management Winged beans have strong nitrogen fixation capacity, and nitrogen fertilizer should be applied at the seedling stage. The amount of nitrogen fertilizer should be controlled throughout the vegetative growth period, otherwise it will affect flowering and pod formation. When entering the reproductive growth period, that is, during the flowering and pod-forming period, phosphorus and potassium fertilizer should be applied again. Generally, the topdressing of the buds is repeated once in the initial stage of flowering, and the ternary compound fertilizer (NPK is 15-15-15) 15 kg per 667 m2, or 50 kg of phosphate fertilizer and 10 kg of potassium fertilizer to promote multi-flowering and pod formation.

Winged beans prefer a moist environment, should pay attention to watering, keep the field moist, especially in the flowering and pod-forming period, maintaining sufficient water is conducive to satisfy the growth of the branches and flowering pods, but avoid waterlogging in the field. Otherwise, too much water will affect the formation of root nodules and the growth and development of roots, causing rotten roots and fallen leaves, falling flowers, and falling pods.

4 Harvesting and retaining the seeds of the four-legged bean pods in the morning and evening

It affects the quality of the pods, so it is necessary to strictly control the picking time. Generally, 10 to 12 days after flowering (days), when the pods are green and not lignified, tender pods are harvested. At this time, the pods are crisp and tender and have few fibers. If the picking is too late, the pods are lignified, the fibers are increased, and the pod walls are hard and inedible. When planting in the field, it can be harvested for 5 days (days) and harvested once. The whole growth period is about 3,000 kg per 667 m2.

For the purpose of harvesting dried beans (for grain and oil raw materials or seed retention), the pods may be browned and picked at the base when they are dry to prevent natural cracking of the pods. The flowering to maturity of the pods generally takes 40 to 50 days (days) in Hainan, and 150 kg or more of dried beans per 667 m2.

It is understood that the Winged Bean is very delicious, and the appearance is peculiar. It is very popular in Hainan. It is a new type of special vegetable that has only recently come out. It has very good planting prospects. You growers can sort out the long-term giants of Hainan Province according to Xiaobian. The main cultivation techniques of the tyrant are tested.
