A Detailed Guide to Kidney Bean Planting Methods and Technical Points

SummaryLand preparation and fertilizing: After tilling the soil, form ridges and ditches at a spacing of about 20cm, and scatter a small amount of livestock manure or dry grass and wood in the ditches. Sowing and raising seedlings: The seeds need to be sun-dried for 2-3 days, then soaked for disinfection before sowing; methods such as drilling, dibbling, and transplanting can be used. Temperature: It has poor cold resistance, and the suitable temperature for growth is around 15-28°C. Fertilizer and water: After planting, watering and fertilizing are needed, followed by 2 additional top dressings later. Trellising: Set up trellises when the kidney bean seedlings grow to 30cm.

I. Land Preparation and Fertilizing

1. Kidney beans are not suitable for planting in wasteland that has not been cultivated for several consecutive years, because such soil contains many pathogens and pests, which may very likely prevent kidney beans from producing pods. Therefore, when preparing the land, try to till the soil after the previous crop has been harvested, as this can reduce the occurrence of some diseases and pests.

2. When preparing the land, you can form ridges and ditches at a spacing of about 20cm, then evenly scatter a small amount of dry grass and wood or livestock manure on the ridges, and then wait to sow.

II. Sowing and Raising Seedlings

1. Because the seed coat of kidney beans is relatively hard, direct sowing will cause slow sprouting. Therefore, you can first put the seeds in the sun to dry for 2-3 days, then soak the seeds in formalin solution for about 10 minutes, remove them and rinse them clean with water, and let them dry before sowing.

2. There are 3 sowing methods. The 1st is drilling, which means sowing the seeds row by row on the prepared ridges. The 2nd is dibbling, in which holes can be made on the ridges at a spacing of 30cm per plant for sowing. The 3rd is transplanting, in which kidney bean seeds can be raised on a seedbed, and when they grow to about 10cm, they can be transplanted into the prepared field.

III. Temperature Management

1. Kidney beans have relatively high temperature requirements, and their cold resistance is also relatively poor. They will also pause growth under high-temperature conditions. Therefore, when planting kidney beans, attention should be paid to temperature regulation. In the Hunan region, kidney beans can be planted in spring from March to April, and then around June they will produce kidney beans.

2. During this period, the temperature needs to remain stable at around 15-28°C. Moreover, kidney beans will stop growing when the temperature is below 10°C, and the plants will be burned to death when the temperature is above 30°C. Therefore, planting should be carried out according to the seasonal changes of the local area. At the same time, greenhouse planting can also be used, which also makes temperature management relatively simple.

IV. Fertilizer and Water Management

1. After planting, kidney beans need 1 watering and fertilizing. In order to ensure that the kidney bean seedlings in the field grow uniformly, manure and urine water can generally be used for irrigation, then mixed with 50 jin of urea,

2. For the 2nd fertilizing, you can choose the time when the kidney beans are climbing. Per mu, 20 jin of phosphate fertilizer, 20 jin of potassium fertilizer, and 30 jin of urea can be mixed and broadcast.

3. For the 3rd fertilizing, you can choose the time when the kidney beans are flowering and setting beans. It can promote the flowering period and increase the pod-setting rate. Per mu, 20 jin of phosphate fertilizer, 20 jin of potassium fertilizer, 30 jin of urea, and 30 jin of boron fertilizer can be mixed and broadcast.

V. Trellis Management

You can choose to build trellises or sheds when the kidney bean seedlings grow to about 30cm. Ropes can be used to connect the trellises, and then the kidney bean seedlings can be guided onto the trellises to let them climb and grow naturally. This yields much more than growing by crawling on the ground, and at the same time it can also reduce the occurrence of diseases and pests.

VI. Preventing and Controlling Diseases and Pests

Common diseases of kidney beans include leaf blight and root rot. To prevent these two diseases, field management must first be done well. Then, when the disease occurs, Duolingjun solution can be sprayed for control. Common pests of kidney beans include aphids, inchworms, cabbage worms, armyworms, etc. A relatively effective control method is to spray trichlorfon solution or Bordeaux mixture for control.
