A special medicine for straightening and lengthening beans.

Bean is one of the popular vegetables widely cultivated in northern China, and its popularity ranks first among all kinds of vegetables. However, many farmers responded that the beans did not grow straight and the sales were not good. So, what are the specific drugs for straightening and lengthening beans?

First, what are the specific drugs for straightening and lengthening beans?

The specific drugs for bean straightening and elongation are bean and vegetable tender straight flower pod treasure, Suele boron, Yuhualing No. 1, Yuhualing No. 6 and so on. In addition, special foliar fertilizer for bean elongation and straightening can also be used.

Second, what is the reason why the beans do not grow straight?

The main results are as follows: 1. The quality of beans is poor, first of all, consider the advantages and disadvantages of varieties. When some varieties bear pods, they have more bent pods, and some have poor resistance to the environment, and when they encounter adverse climate, the quality becomes very poor. Therefore, it is the key to select seeds with strong stress resistance and good quality.

2. Boron deficiency in the early stage. Boron deficiency in beans, kidney beans and other legume vegetables will affect flower bud differentiation, even if the pods sit, it will lead to bending and other problems, poor merchandise. The way is to spray boron foliar fertilizer such as carbon energy boron before flowering.

3. The temperature is too high. The suitable temperature for bean growth is 20 ℃ 25 ℃ during the day, 15-18 ℃ at night and 23-25 ℃ at flowering stage. If it exceeds 30 ℃ during the day, it will affect the setting of pods and reduce the quality of setting pods. Therefore, the flowering period at noon must be observed in the shed, timely ventilation, control the shed temperature.

4. Drug damage. Legume vegetables are sensitive to many vegetables, such as pyrimidine, mancozeb, isobarbazide or prochloraz, etc., which can easily bend the pods if excessive application. Beans are very sensitive to poisonous alum and are prone to drug damage, resulting in pod deformities; there are also beans that are damaged by spraying copper preparations and anthrax Fumei, with pods bent in light cases and fallen leaves and pods in heavy ones. In addition, pesticides should also be paid attention to in the process of application to avoid drug damage. Aiming at the drug sensitivity of legume vegetables.

5. due to unpollinated fertilization, it is related to temperature, and boron deficiency is also curved and few grains.

In addition to using specific drugs to lengthen and straighten beans, excellent varieties and reasonable fertilization can be selected to increase production and income.
