How long is the growth cycle of long beans?

Introduction to the growth of long beans

Long beans have a wide adaptability to soil and can be planted in all soils except for heavy clay and low-lying and humid plots, but they prefer fertile, loose loam or sandy loam. They are native to tropical Africa and are widely cultivated in China.

Carob growth cycle

Long beans like a warm environment and are not very demanding on the soil, but they do like soil that is fertile, loose, and has strong water retention capabilities.

Long beans are mainly planted in spring and autumn, and their growth cycles are different. The growth cycle in spring takes about 120 days, and in autumn it takes about 100 days.

Growth rate of long beans

The growth process of long beans mainly goes through seed planting, sprouts, bean seedlings, vines, flowering, fruiting, and death. Its growth rate is slow.

Growth cycle management of long beans

The yield of different varieties of long beans is also different. The yield of No. 2 is 2,500 kilograms per mu, and the yield of Xiabao is 2,000 kilograms per mu.

Temperature management: Long beans are resistant to high temperatures, but have weak cold resistance. The seeds germinate faster at 25-35℃. The suitable temperature during the flowering and pod-setting period is 25 to 28 degrees. It can still pod at above 35℃. It grows slowly at around 15℃, and its growth is inhibited below 10 degrees. The plants will freeze to death when the temperature approaches 0 degrees.

Fertilization management: Long beans grow vigorously and have a large demand for fertilizer. Phosphorus fertilizer is mainly applied, followed by potassium fertilizer, and nitrogen fertilizer is the least. In the early growth stage, its root system is not fully developed and its nitrogen fixation ability is weak. Therefore, a certain amount of nitrogen fertilizer needs to be applied, but the amount should not be too much. After entering the flowering and podding stage, phosphorus and potassium fertilizers are mainly applied to promote flowering and fruiting.
