The latest broad bean field management techniques tutorial

Broad bean, also known as Hu bean, Buddha bean, Luohan bean, orchid bean and so on, is mainly distributed in Sichuan, Yunnan, Hunan and Hubei and other places in China. Broad bean is a kind of plant which is easy to grow because of its strong adaptability to the growing environment. So do you know how to grow broad beans? How to carry on the field management operation in the process of planting broad bean? Next, let's study together.

1. Rational drainage and irrigation

Broad bean has the characteristics of being wet, afraid of stagnant water and afraid of waterlogging, so when we plant broad bean, we need to do a good job of water management in the field. First of all, we should choose a suitable planting land, the drainage permeability of the planting land should be good; the second is to keep the soil moist, and when the soil is dry, we should water quickly, not slowly, and at the same time, the amount of water should not be too large. Watering depends on the weather and the water needs of broad beans at their stages of life. There is in the rainy weather, or heavy rainfall, continuous rainfall weather, or timely discharge of excess water in the field, so as not to cause disease, resulting in a reduction in the yield and quality of broad beans.

2. Scientific fertilization

In the process of planting broad bean, fertilization is a very important step in field management. The general principle of applying fertilizer to broad bean is to apply appropriate amount of nitrogen fertilizer, increase phosphorus fertilizer, potassium fertilizer and supplement micro-fertilizer. In the seedling stage of broad bean, we mainly use nitrogen fertilizer to promote the growth of the plant as a whole and promote flowering. When broad bean enters the flowering stage, we mainly use ternary compound fertilizer for topdressing, and we also need to use a small amount of nitrogen fertilizer. At the time of broad bean pod, we mainly use compound fertilizer, and appropriately increase the application of phosphorus and potassium fertilizer. Finally, the foliar fertilizer is sprayed in time after each harvest.

3. Pruning and topping

In order to ensure the high yield and high quality of broad bean, proper branch and leaf finishing and topping are very necessary. The main stem of broad bean does not bear pods, and even if the yield of pods is not high, then if we want to produce high yield of broad bean, we must promote the growth of branches. In general, we will carry out coring and topping treatment, that is, we will remove the heart leaves on the main stem, promote the growth of lateral branches, and so on when the lateral branches grow to a certain length, they will be coring again until the complete plant shape is formed. Secondly, in order to maintain the reasonable permeability in the field, the side branches which are too dense or do not grow well should be thinned properly.

4. weeding at the right time

Now there is a very simple way to weed broad beans, that is, after broad beans are sown, but before sprouting, use special herbicides for field crops to weed, at this time the weed control effect is very good. When broad bean emergence, we can not use chemicals to weed, so we can only carry out mid-tillage weeding, which can also properly ventilate the soil, improve the conversion rate of nutrients, and promote the growth of broad bean.
