1, seedling stage: 1-2 days after sowing, the seed coat will expand and crack to reveal the buds, and then slowly grow stems, cotyledons gradually separate and grow true leaves, and finally the cotyledons fall off. 2, fast-growing period: in the branch and root development and maturity, and then gradually blossom pods. 3, pods: in the appropriate temperature, in order to blossom and pods. 4, maturity: in the pods from the green gradually turned black, that is, it is ripe and can be harvested. 5, harvesting period: after pulling out the roots together, put them under the sun for exposure.

I. Seedling stage

1, after sowing, watering in time, covering the seeds with thin soil.

2, in 1-2 days, the seeds will absorb water and swell up, the seed coat will be cracked after sprouting white, and then gradually grow stems.

3, cotyledons will gradually separate, rooted and grow true leaves, cotyledons will slowly fall off.

4, after the growth of real leaves, timely watering and fertilization, fertilizer can choose light fertilizer.

Two, fast-growing period

1, legumes should not apply a lot of fertilizer, because it itself has the ability to fix nitrogen.

2, the plant grows for a long period of time, after the branching and root development and maturity, only gradually flowering and pods.

3, when the temperature is high, timely watering of the plant.

Three, podding period

1, predict the time of flowering weather conditions, adjust the sowing time.

2, high temperature and rainy season will cause no pods or drop flowers, seriously affecting the flowering rate.

Four, maturity

1, after the pods gradually turn from green to black, only after the start of harvesting work.

2, this period does not need to carry out water and fertilizer management, only need to water a moderate amount of water in the drought can be.

3, timely preparation to prevent pests and diseases.

Five, harvesting period

1, harvesting needs to be pulled out together with the roots, and then placed in the sun for exposure.

2, dry the soil and remove it, the pods need to be sun-dried until they can explode on their own.

3, Continue to dry the pods on a mat, while it needs to be wrestled and the seeds removed and sieved.
