How to grow Dutch beans

The Dutch bean is a twining herb of the butterfly family. Its origin is in Southeast Asia. It is called the Dutch bean because the Dutch brought it to China. Dutch bean has a high nutritional value, it contains high protein and amino acids needed by the human body. It is widely cultivated in China, and it is a kind of crop with good economic value. So how to grow Dutch beans? The following editor brings you the planting method of Dutch beans, let's have a look!

1. Land selection and preparation

The growth ability of Dutch bean is relatively strong, there is no great requirement for soil, and it can grow normally in all kinds of soil. But pay attention to the pH of the soil, Dutch beans can not grow in acidic soil, if the soil is strong acid, then need to sprinkle lime in the soil to neutralize pH. And Dutch beans should be rotated for at least 4 years, otherwise the incidence of diseases and insect pests is serious. After selecting the site, prepare the soil in time, turn the soft soil deeply to improve the soil permeability, and then apply appropriate amount of base fertilizer, which is mainly farm manure, adding appropriate amount of calcium superphosphate and potassium chloride. Make a good flat bed to facilitate sowing and later management of harvesting.

2. Seed selection and soaking

Seed selection should be done before sowing, and the seeds should be put into salt water to remove the floating dried seeds and seeds of diseases and insect pests. Then do a good job of accelerating germination, soak the seeds in water for 5 hours, put them in the appropriate environment to promote germination, and then put them in a low temperature of 1 degree for about half a month after planting white dew buds. Then mix the seeds with rhizobia, increase the number of root nodules, improve the growth rate of stems and leaves and the rate of flowering and fruiting, so as to achieve the purpose of increasing production. Last night, we sowed seeds at the right time after a series of measures to reasonably control water and fertilizer and promote seed germination and emergence.

3. Field management

After sowing, it is necessary to loosen the soil in time, raise the soil temperature, promote the seed to take root and germinate, and ensure the healthy growth of the seedlings. If it is sowing in autumn, then carry out soil cultivation measures before the beginning of winter to do a good job of heat preservation for the winter. Before the Dutch bean blossoms, nitrogen fertilizer should be applied once to promote plant growth and work with loosening soil to preserve soil moisture. When podding begins, increase the frequency of watering to the ratio of potassium and phosphorus in the fertilizer. Ensure that the soil is in a moist state and provide sufficient water for the development of pods. When the plant grows to about 35 cm, it sets up to draw vines to ensure the healthy growth of the plant.

4. Timely harvest

The growing season of Dutch beans is quite different from that of other legume vegetables, so there is a certain gap in the time of harvest. For example, when planting in June, because the temperature is relatively high, the growth ability of Dutch beans is enhanced, and its growth period takes only about two weeks. But on the contrary, in winter, the low temperature environment is not suitable for the growth of Dutch beans, so the growth period takes about a month. Therefore, our harvest time should be determined according to the planting time, and there is also the planting direction and so on. There is no specific harvest time, which needs to be controlled at your discretion.

The above is a brief introduction to how to grow Dutch beans. The growing period of Dutch beans is not very long, so the incidence of diseases and insect pests is low. However, we can not neglect management, improper management will increase the incidence of diseases and insect pests, so we should not only do a good job in field management, pest control work is also indispensable. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
