When is the best time to plant red beans (the best time and method to plant red beans)

What is the best month to plant red beans?

The sowing and planting time of red beans, the growth cycle, etc. are different in different regions. In some areas, red beans can be planted for two seasons, while in many areas, they can only be planted for one season .

Taking the planting time in most areas as an example, it is usually best to plant between April and June each year. April is an early planting month, and planting in May and June can produce a high yield and harvest .

The temperature at this time is basically stable at around 20 to 28 degrees, and the water is relatively sufficient, which is very suitable for the germination of red bean seeds.

Of course, you can plant it a little later, but the yield will be reduced because planting too early or too late is not conducive to management.

Moreover, after sowing, red beans do not sprout in time, and the nutrients are consumed and they are prone to diseases. When sowing, pay attention to controlling the sowing depth, otherwise it will cause uneven emergence.

How to sow and plant red beans

① Reasonable seed selection

There are many types of red bean seeds on the market now, including large red beans and small red beans. Among them, large red beans and small red beans are divided into many types, so the first thing we need to consider when selecting seeds is the yield of red beans .

The second is whether the germination rate of the seeds is high, and the last is the various resistances of the seeds. We will choose red bean varieties suitable for local planting based on the soil, climate, temperature, rainfall and other factors in different regions. At the same time, no matter whether the variety is good or not, you cannot buy old seeds, the survival rate is too low and the loss is too great.

②Scientific land preparation

Since red beans have a stronger ability to adapt to the environment than other crops, we can choose to ignore the choice of planting site.

However, one thing that must be taken into consideration is that the moisture in the planting area should not be too much, that is, the soil humidity should not be too high, otherwise it will easily cause disease and affect the yield.

When preparing the land, we need to clear away all debris in the field, deep plow the soil, and then sprinkle a layer of lime to eliminate bacteria.

After exposing the soil to the sun for about ten days, sprinkle a layer of livestock manure or wood ash on it, make ridges and furrows, and then wait for sowing.

③ Sowing seeds at the right time

If the soil is too sticky, it cannot be sown, otherwise it is easy to have germination problems. The sowing temperature should be controlled at 15-18℃ . Red beans are usually planted in July-August at the latest, and are generally sown by broadcasting .

The sowing rate should be increased for early-maturing varieties and low-lying areas, and reduced for late-maturing fields and fields requiring high fertilizer and water management.

If conditions permit, the seeds can also be mixed to enhance their disease resistance and ensure the cultivation of high-quality seedlings.

④Scientific fertilizer and water management

Adzuki beans need to be fertilized with seed fertilizer, flower fertilizer, and granular fertilizer . Seed fertilizer is ammonium sulfate and superphosphate. Potassium sulfate should be added to potassium-deficient plots. When applying seed fertilizer, care should be taken to avoid burning the roots.

Urea and potassium sulfate are applied during the flowering period, and foliar spraying is mainly used during the grain filling period. For plots with fertilizer deficiency, foliar spraying is carried out to supplement nutrients, and the fertilizer is mainly urea plus potassium dihydrogen phosphate.
