Planting in the Yangtze River basin is generally based on overwintering cultivation, and planting in the open field in the south is generally divided into spring and autumn, sowing in March in spring and sowing in September in autumn. The growth ability of Dutch beans is very good, and there are not too many requirements for planting soil, and they can basically grow normally in all kinds of soil. Seed selection should be done well before sowing. First, put the seeds into salt water to remove the withered seeds and unhealthy seeds floating on them.

First, the planting time and method of Dutch beans

1, Dutch bean is a plant that likes to grow in cold environment. Its requirement for light is long sunshine, and its heat resistance is poor. Generally, the cultivation time will be different according to the different planting areas. Planting in the Yangtze River basin is generally based on overwintering cultivation, and planting in the open field in the south is generally divided into spring and autumn, sowing in March in spring and sowing in September in autumn.

2. The growth ability of Dutch beans is very good, and there is no requirement for the soil planted. It can basically grow normally in various soils. But the ph value of soil must be paid attention to, because it can't grow in acidic soil. If the acidity in the soil is too strong, it is necessary to increase the ph value of the soil. You can sprinkle lime in the soil to neutralize the pH value of the soil.

3. Before preparing for sowing, seed selection should be done well. First, put the seeds into salt water to remove the withered seeds and unhealthy seeds floating on them. Then do a good job of accelerating germination, soak the seeds in water for about 5 hours, then put them in a suitable environment to accelerate germination, and then put them into 1? It can be sown in a low temperature environment of about 15 days.

Second, the management technology of Dutch beans

1. Peas should be ploughed and loosened in time after sowing, and the temperature of the soil must be raised, which can promote the seeds to take root and sprout better and make the seedlings grow better. If it is sown in autumn, it should be cultivated before winter, so as to do a good job of heat preservation in winter.

2. Before sowing, 2500g organic fertilizer, 20kg urea and 40kg potassium sulfate should be applied per mu. In the later stage, if the growth is good and the planting density is high, an appropriate amount of topdressing can be used for 2-3 times until the vines grow and pods are formed. In addition, it needs different fertilizers at different stages of its growth, but mainly phosphorus, potassium and nitrogen.

3. The demand for water in the whole growth period of Dutch beans is relatively large, and only sufficient water supply can make them grow vigorously. But if you water too much, there will be problems of root rot and seed rot. Therefore, we must pay attention to moisturizing, control the time and amount of watering, and judge whether to water according to the soil moisture.
