What are the key points of the planting technique for the pole bean "Jiadouwang"?

Jiadouwang is a type of common bean with thick flesh and few strings, relatively high resistance to pests and diseases, and relatively high yield, and it is well loved by consumers. Let's take a look at the planting technique for Jiadouwang.

1. Land preparation

When planting Jiadouwang, choose soil with good drainage and thick fertility. Before preparing the land, apply base fertilizer first. For the base fertilizer, choose fully decomposed farmyard manure as the main component and add an appropriate amount of chemical fertilizer. After fertilizing, deeply plow the soil, level it, and make beds. Generally the bed width is 1.2 m, the bed height is 6 cm, and the distance between beds is 70 cm.

2. Planting

First soak the seeds in diluted fungicide for 2-3 hours, which can effectively kill residual pathogens. Then rinse them clean with water and sow. Two rows can be sown per bed, with a row spacing of 40 cm and a plant spacing of 30 cm, placing 3 seeds per hole. If the temperature is too low when sowing, cover with plastic film.

3. Fertilizing and watering

During the seedling stage, too much water and fertilizer can easily cause root rot in Jiadouwang, so water and fertilizer should be controlled during the seedling stage. During the vine-running stage of Jiadouwang, fertilize and water once together with intertillage, which can promote vine growth and flower bud differentiation. When Jiadouwang is flowering and fruiting, it needs a large amount of water and nutrients. Generally, fertilizing at this time should be combined with irrigation. After Jiadouwang flowers and enters the pod-setting stage, the nutrients it needs are consumed very quickly, so at this time the soil should be kept moist while applying less nitrogen fertilizer, or trace elements such as iron and zinc can also be sprayed to supplement foliar nutrients. In the late growth stage of Jiadouwang, if the plants have not prematurely aged, topdress appropriately 1-2 times to promote the Jiadouwang plants to produce new flowers, extend the harvest period, and increase yield.

4. Trellising

When Jiadouwang begins to send out vines, bamboo poles can be used for trellising. Use bamboo poles to build a herringbone shape, and guide the vines along with the trellising so that Jiadouwang grows upward along the poles.

5. Pest and disease control

Common pests and diseases of Jiadouwang include bean pod borer, leaf mites, rust, gray mold, root rot, and so on. Spray pesticides for control during the peak incidence period of Jiadouwang, and spray pesticides promptly at the early stage of disease to prevent the spread of pathogens.

The above are the methods for planting and managing Jiadouwang. I hope everyone can grow high-quality, high-yield Jiadouwang.
