2. Generally, the water needed to be absorbed by the seed germination of green beans is not more than half of the seed amount. If the water is too much, the seed will rot and the seed will not germinate at all, so it is necessary to provide a loose and breathable soil environment for the seed germination, so that the seed of green beans will germinate in about three to four days.
3, first of all, green beans are very strict about water, like to be wet, afraid of drought and avoid waterlogging. You can water less before flowering, and you don't have to water it if you don't do it under normal circumstances.
4. It needs to be watered many times from flowering to pod setting, usually every 2 to 3 days, and the watering times of green beans should be appropriately increased when the temperature is relatively high.
5. Secondly, it needs to be combined with watering for fertilization, and in the initial growth, it should be fertilized with nitrogen-based organic fertilizer.
6. Then spray 1 time organic fertilizer every/kloc-0 to 2 weeks from flowering to pod setting, and it must be compound fertilizer such as nitrogen, phosphorus and potassium. If the temperature around the growth of green beans is lower than 15℃ and higher than 20℃, it is easy to cause flowering. In summer, it is necessary to shade and cool down, and it is absolutely forbidden to get wet for a long time at low temperature.
