When to Plant White Kidney Beans? Detailed Guide to Planting Time and Methods

The planting time for white kidney beans is in spring and autumn, and the planting time differs depending on the region, which can be determined specifically according to the local climate. The planting method is to first prepare a flat, fertile field, then deep-plow it and apply sufficient base fertilizer. Then select some healthy, plump, high-quality seeds and sow them into the soil, and finally cover them with soil and put on a plastic film. After the seedlings emerge, carry out hilling and weeding, water and fertilizer management, and trellising, and then the beans will grow.

High-yield planting methods for white kidney beans:

1. Land preparation and fertilization

We generally do not plant in wasteland that has not been cultivated for several consecutive years, because that kind of soil contains relatively many pests, diseases, and pathogens, is not suitable for planting white kidney beans, and very likely will fail to produce pods. When preparing the land, we try to plow the land after the previous crop has been harvested, which can reduce some pests and diseases. When preparing the land, we generally make ridges and furrows at a spacing of 20 to 20 physical units, then evenly spread a layer of livestock manure or dry grass and wood on the ridges, and then we can wait to sow.

2. Sowing and raising seedlings

The seed coat of white kidney beans is relatively hard, so if sown directly, sprouting is very slow. Therefore, we first put the seeds in the sun to bake for two or three days, then soak the seeds in a formalin solution for about ten minutes, then take them out and rinse off the chemical with clean water, and then dry them before sowing. There are three sowing methods. The first is drilling, that is, sowing the seeds row by row on the prepared ridges. The second is hole sowing, making holes on the ridges at a spacing of 30 cm per plant and sowing. The third is transplanting. First, cultivate the white kidney bean seeds on a seedbed, and when they grow to about 10 cm, transplant them into the prepared field.

3. Temperature management

White kidney beans have relatively strict temperature requirements. First, their cold resistance is extremely poor. Second, under high-temperature conditions they will also stop growing. Therefore, when planting white kidney beans, special attention must be paid to temperature regulation. In the Hunan region, we generally plant white kidney beans in March or April in spring, and then around June they will produce white kidney beans. During this period the temperature is basically stable at around 15 to 28 degrees, so the temperature is just right, neither hot nor cold. White kidney beans will stop growing when the temperature is below 10 degrees, and will burn to death in an environment above 30 degrees. Therefore, we should plant as much as possible according to the seasonal changes of the region, and at the same time we can also use greenhouse technology for planting, which makes temperature management simpler.

4. Fertilizer and water management

The fertilizer and water required throughout the entire growth period of white kidney beans are as follows. Generally, under normal circumstances, after white kidney beans are planted and established, the first watering and fertilization are needed. At this time, the purpose is to make the growth of the white kidney bean seedlings in the field more uniform, so we generally water with human excrement and urine, then mix in 50 jin of urea. The second fertilization is when the white kidney beans begin to climb. At this time they need a large amount of nutrients, but it must also be reasonably controlled to prevent excessive vegetative growth without flowering and podding. On average, 30 jin of urea, 20 jin of phosphate fertilizer, and 20 jin of potassium fertilizer are mixed and broadcast per mu. The third fertilization is when the white kidney beans flower and set pods. We can promote the flowering period and also increase the pod-setting rate. For this fertilization, on the basis of the second fertilization, an additional 30 jin of boron fertilizer is applied.

5. Trellising management

In order to increase the yield of white kidney beans, we generally build some trellises or sheds when the white kidney bean seedlings grow to about 30 cm, connect them with ropes on each trellis, then guide the white kidney bean seedlings one by one onto the trellises and let them climb and grow along the ropes on the trellises. In this way, the yield is much higher than when they crawl and grow on the ground, and at the same time it also avoids the occurrence of many pests and diseases, so trellising is very necessary.

6. Disease control

White kidney beans have relatively few diseases. The most common are probably leaf blight and root rot. For these two diseases, ordinary growers know how to prevent them, since they are common problems of all crops. First, to prevent these two diseases, we must do a good job in field management, and then when the disease occurs we can use carbendazim solvent for control. The most important thing is to prevent insect pests, mainly armyworms, aphids, inchworms, and cabbage worms. The most effective control method is to spray the bean seedlings with trichlorfon solvent or Bordeaux mixture.

The above is a related introduction to the planting time and methods of white kidney beans. We hope it is helpful to everyone.
