Kidney bean cultivation methods and precautions

1. Maintenance methods

1. Temperature: It is relatively cold-resistant but not high-temperature resistant. It will only be frozen when the climate is below five degrees. During the growing season, the temperature must be controlled above 20 degrees. When it is above 30 degrees, you need to start helping to cool it down, otherwise pollination will be difficult.

2. Watering: During the entire growing period, a large amount of water is needed. If the climate is humid and there is a lot of rain, there is no need for manual watering. If there is a dry climate, it is necessary to water it every week, and each time you water it, make sure it is watered thoroughly.

3. Fertilization: In addition to the base fertilizer mixed in the soil before planting, fertilizer needs to be applied twice during its growth period. The first time is after planting, when you need to apply manure and urine water to it. Mix some urea in the manure and urine water to promote the growth of seedlings. The second time to fertilize is when it starts to grow seedlings. At this time, it needs a lot of nutrients, but the amount of fertilizer should also be controlled to avoid the phenomenon of excessive growth without flowering or fruiting. Generally speaking, one acre of land requires 30 kilograms of urea and 20 kilograms of phosphate fertilizer. Depending on its growth conditions, you can apply fertilizer again as needed when it blooms and bears fruit, in order to promote the plant to set beans.

4. Light: It is a cross-pollinated short-day plant. If the light time is short and the sunlight is sufficient, the time it takes to bloom, bear fruits and mature will be shorter. vice versa.

2. Breeding techniques

1. Reproduction: It can be propagated by sowing. Soak the seeds in 1% formalin solution for 20 minutes in advance, and then wash them with clean water. This is to kill the anthracnose bacteria on the surface of the seeds. Soak the seeds in warm water for 12 hours and germinate them at a temperature of about 25 degrees. After the seeds are topped, place them in a cool place for 12 hours before sowing. When sowing, spread it directly on the ground evenly. Cover it with a layer of soil after sowing. Generally, seedlings will emerge in two weeks.

2. Pruning: During the growth process, dry and rotten branches need to be pruned off in time.

3. Problem Diagnosis

1. Pests: The pests that it is more susceptible to include cutworms and flea beetles. If found, they can be killed manually or poisoned with plant-based pesticides such as pyrethrum.

2. Pathology: It is more susceptible to powdery mildew. If found, Bordeaux mixture should be used for prevention and treatment.
