Beans are one of the most common vegetables grown in our lives. Farmers who have planted beans have known that peas are vine-like plants that need to be climbed during the growing process. Few people know that in fact, beans need to be pruned. Many friends don't understand it very well. So Xiaobian will talk about the reasons for the bean pruning and its methods.
First, the reason for the bean pruning
In the process of planting beans, if we do not timely and reasonably pruning it, it will lead to the growth of the branches of the beans, and the branches and vines inside the beans will block the light. The bud differentiation of the lateral branches of the beans is also reduced, resulting in a low flowering rate and a low pod rate. The yield in the middle and late stages is low, and the "resting" is severe in the hot season, which eventually leads to a decrease in the production of the beans.

Second, the method of bean pruning
1. From the base of the bean to the side bud that is too close to the ground, it needs to be wiped out in time: Because the beans are long, the beans that grow at the bottom of the plant will touch the ground, which is especially vulnerable to infestation by underground pests or infection. Not only if the side buds in the lower part of the bean horn grow too much, they will take away some of the nutrients of the main branches, thus affecting the growth of the main branches. Therefore, when the lower lateral bud grows to a length of 2-3 cm, the lateral bud should be wiped out in time, which can also improve the ventilation and light transmittance of the base of the bean plant, so that the time of flowering and pod formation of the bean can be earlier.
2. During the fruit-bearing period, pay attention to the group tips, and perform the topping treatment on the side branches. When the flower buds and the leaf buds grow together at the same time in the upper part of the main vines of the beans, the side branches of the bean buds should be erased. When only the leaf buds in the upper part of the main vine are sprouting, you can wait until the side branches of the beans have two leaves, and then perform the topping treatment, which can also promote the growth of the bean buds, thereby increasing the number of flower buds and increasing the fruit setting rate. .
3. Topping the main branch of the bean knives: When the main branch grows above the steel wire, it is necessary to pick the heart in time, which is beneficial to control the growth of the plant, increase the number of collaterals and promote the differentiation of the lateral buds, and increase the number of sitting pods.

The above is the reason for the pruning of the bean plant and the introduction of the method, I hope to bring some help to the farmers.

Drug intermediates -Pharmaceutical intermediates: A material that is produced during a process step of the drug substance and must undergo further molecular changes or refining before it becomes a drug substance. The intermediates can be separated or not separated.
Active Pharmaceutical Ingredient (APIS)(or Drug Substance) : Active Pharmaceutical Ingredient (API)(or Drug Substance) : Any substance or mixture of substances intended to be used in the manufacture of pharmaceutical products and, when used in pharmaceutical products, to be an active ingredient in pharmaceutical products. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, management or prevention of disease, or can affect the function and structure of the body. As can be seen from the definition, the Intermediates APIS is a key product of the previous process of manufacturing the API and has a different structure from the API
Finally, for example, amoxicillin capsules are called preparations, amoxicillin is called APIS, and 6-APA is called Veterinary Intermediates APIS.
Penicillin potassium for injection is called preparation, penicillin potassium is called Veterinary raw materials, and green potassium industrial salt is called intermediate
