Winged bean prefers a warm and humid climate, does not tolerate frost, grows well at temperatures of 20-25°C, grows poorly below 15°C or higher than 35°C, and the seed germination temperature is about 25°C.
Winged bean roots are well-developed, more resistant to drought and irritability, but require a moist environment; they require sufficient water during flowering and podging, and are too dry to produce low pods. Therefore, the cultivation of winged beans should choose loose and fertile, water permeability, easy to drain and easy to fill the soil. In order to facilitate planting, the cultivation techniques are now described as follows:
1, selection, site preparation. Winged bean is a bean root nodule crop, and fertile, water-permeable and neutral loam soils should be selected to be poorly grown in sandy soils with heavy or poor soil quality. Before planting, the base fertilizer must be applied. Generally, 1,000-1,500 kg of organic fertilizer is applied per mu, 500 kg of grass-wood ash or earth-oil ash, and 50 kg of phosphate fertilizer. Then, the width of the plant is 50-60 cm, and the height is 20-25. In centimeters, the sulcus is 25-30 cm wide. After the scorpion has been well-grounded, it is planted at the center of the pod by digging 60-70 cm, and 2-3 seeds per hole.
2, sowing time and method. According to the temperature required for the wing bean to germinate and grow, as long as the local temperature is stable at about 25°C, the seed can be sown, and the temperature can be transplanted at a temperature above 20°C. It can be planted in the south of China from March to June, planted in the north around June, and the greenhouse greenhouse can be sown and cultivated throughout the year:
The production of breeding seed sowing and potato block propagation in two ways: generally seed sowing. Seed treatment must be carried out with seed propagation. The steps are: drying seeds for 1-2 days, then hot-stamping with 45-55°C warm water for 10 minutes, then soaking for 2-3 days, changing the water once a day. When the seed sucks enough water, remove and drain the water and allow the seeds to dry. Planting line spacing should be controlled at 90 cm and 60 cm. It is advisable to plant 2-3 grains per hole, then cover ash, cover soil 3-4 cm. If the seedlings are transplanted, they must be transplanted to Daejeon until they have grown 4-6 leafy leaves.
3, field management and fertilization
(1) Dingling seedlings. When the seedlings begin to unearthed one week after sowing, they shall timely check the seedlings and make up the seedlings. When the seedlings grow to 7-8 leaves, they shall be subjected to thinning, timely removing the weak seedlings, disease and seedlings, malformed seedlings, and leaving each hole to be selected. 2 healthy strains with healthy growth, no pests, and 1500-2000 strains per mu.
(2) The introduction of vines and cultivators. Winged Bean is a vine crop, 30--40 days after emergence, when vines are started, timely use bamboo or wood to build adult characters or triangular shelves, height 1.5 meters above, and cultivating and weeding 1-2 times before drawing vines. After weaving, the vines were sown and then weeded again and again 1-2 times. After the branches and leaves were closed, a 15-20 cm soil was cultivated and the cultivator was stopped. Flowering and podling period is to adjust the contradiction between reproductive growth and vegetative growth, promote flowering and root enlargement, and pick up the heart for growing branches to promote branching, control prosperous growth, reduce flowering, and promote fruition. The branches of the 3 branches and over the branches should be removed in time to save nutrients and increase the fruit setting rate. The removed leaves can be used as animal feed.
(3) fertilizer and water management. Winged bean is a nodule leguminous crop with strong nitrogen-fixing ability and less nitrogen fertilizer should be applied during the seedling stage. The amount of nitrogen fertilizer should be controlled throughout the vegetative growth period so as to avoid causing long growth of branches and affecting flowering and scarring. However, in the period of reproductive growth, that is, flowering and podling, phosphorus and potassium fertilizers should be reused. Generally in the early bud flowering and heavy fertilizer once, every acre nitrogen, phosphorus, potassium compound fertilizer 15 kg, or 50 kg of phosphate fertilizer, potassium fertilizer 10 kg, in order to promote more flowering scar.
Winged bean wet environment, should pay attention to watering, keep the field moist, especially in the flowering and podging period, to maintain adequate moisture is conducive to meet the growth of dendrite and flowering scarring. Ensure production and quality, but avoid waterlogging in the field. Because Winged Bean is a nodule crop, excessive water will affect the formation of root nodules and the growth and development of the root system, resulting in rot roots and fallen leaves, falling flowers and falling down.
4, harvest and retain seed. The quality of pods directly affected by the harvesting of pods in the morning and evening of harvested pods, therefore, must be strictly controlled. Generally 10-12 days after flowering, when the green leaves of pods are not yet lignified, the tender pods are harvested in time for use as vegetables. At this time, the pods are crisp and tender, and there are few fibers. If picking is too late, the pods will become lignified and fibers will increase, and the walls will be rough and inedible. Commodity Daejeon can grasp the harvest once in 5 days. The whole growth period is generally 1500-2000 kilograms per mu.
If the objective is to harvest dried beans (for grain and oilseeds or leave seed), wait until the pods turn brown, and when the base is dry, pick it in time to prevent natural cracking. Cardamom blossom to maturity in the South about 40-50 days, per mu dry beans more than 150 kg.
Root harvest. The roots of Winged Bean are generally harvested before and after the leaves are fallen. In winter, the soil is not frozen, and the roots can be left exposed for the winter. This year, the growth is prosperous, the foliage is luxuriant, the yield is high, and the tubers are larger. If it is cold and frozen in the winter, it must be picked up and stored properly. Wedge bean bean annual production of potato block weight is generally about 1 kg, two years of production of potato block up to 2.5 kg or more. It is worth noting that the four-sided bean pods and the potato blocks compete for nutrients. Therefore, if the aim is to harvest beans, there will be fewer tubers and the yield will be low. If the purpose is to harvest the tubers, they will need to be removed during the flowering and growth period so that the nutrients can grow long, so that the yield per unit can be harvested. 2000 - 5000 kg.
Winged beans and potato pods can be preserved, sowing pods, picking dry in time, dry and sealed. With potato chips as a species, the southern natural habitat can stay in the winter, cold areas in the north are harvested before autumn, stored for the winter, to avoid moisture rot and frost damage.
