Beans are a kind of vegetable that we are very common. Many people like to eat. At present, the market demand for beans is large, and many farmers have planted it. However, many farmers found that the yield and quality of the beans were very low when they were planted with beans. The picking period of the beans was very short, and some beans had less flowering and the pod rate was very low. So what is the reason for this? How to solve it? Let's take a look at it with Xiaobian.

1. Species degradation of self-sustaining varieties
There are many vegetable farmers who like to keep their own seeds. The self-retaining seeds should pay attention to the purification and rejuvenation of the species, and maintain the characteristics of the original varieties. However, the cultivating of the cultivars is very random, leading to the degradation of the species, and some of them are kept from the diseased plants. The seed is infected with bacteria, the early maturity is worse, the pod-forming part is increased, the pod-forming rate is reduced, the pod length is shortened, the weight is reduced, and some pods are mixed.
Solution: In the production, it is necessary to select a good variety that has been professionally purified and rejuvenated or a new variety that has performed well after trial planting.
2, seedling technology has not improved
Beans live on the stems and leaves are strong and less pods, seedlings transplanted more pods. In recent years, the number of seedling transplants has gradually increased, but the live broadcast still accounts for the majority, which is one of the main reasons for the low yield of beans. Beans tend to be prolonged, and there are not many knots or pods.
Solution: Through seedling migration, it can inhibit vegetative growth and promote reproductive growth. Especially after the early spring bean seed broadcast, the temperature is low and the germination is slow. In case of low temperature and rain, the seeds are prone to frost and rotten seeds, and the seedlings are poor. Therefore, it is best to use a nursery bed or a nursery seedling.
3, organic fertilizer is not enough, soil compaction
Organic fertilizer can provide the nutrients needed for crop growth, increase soil organic matter content, renew soil humus composition, increase soil fertility, improve soil physical properties, increase soil fertility and water retention capacity, increase soil biological activity, stimulate crop growth, and Improve detoxification and purify the soil environment.
Solution: In the real pollution-free production of vegetables, we must pay attention to the application of organic fertilizer. Otherwise, it is difficult to meet the requirements of pollution-free production only by applying inorganic fertilizer. The base fertilizer level of beans should be applied to the fertilizer per acre according to the high yield level. 1500 kg or chicken dung 1000 kg.
4, heavy continuous cropping disease
Continuous cropping tends to cause a certain amount of elements in the soil to be absorbed in large quantities, causing deficiency syndrome, and other elements are accumulated. Continuous cropping can also cause damage to soil structure, affecting root growth and crop growth and development. Continuous cropping can also lead to acidification, salinization and disease spread. Continuous cropping is actually the primary reason why beans are getting harder and harder to grow. It is also the first problem to be solved in the pollution-free production of beans.
Solution: Promote water and drought rotation or non-legume crop rotation, deep tillage, fallow, no-till and other measures to reduce pathogens and insect sources, reduce the occurrence of pests and diseases, thereby reducing the use of pesticides and reducing pesticide pollution.
5, the sense of topdressing is not strong
Beans should not be too much water before flowering and pods. Many vegetable farmers have good growth in the early stage, but they have fewer pods or late pods in the later stage, forming a misunderstanding that does not require topdressing. Some think that the base fertilizer does not need topdressing, and some think that the mulching film covers the topdressing. inconvenient. Therefore, the harvesting time is very short. It is only about 20 days from the initial mining to the exit. The harvesting period begins, the flowering and falling pods are serious, the stem vines grow and decline, and there is basically no turning over, resulting in low yield.
Solution: Starting from the initial stage of pod formation, chasing compound fertilizer every 7~20 days, and chasing 2~3 times, it is necessary to improve quality, prolong pod formation and increase yield.

6, disease prevention and pest control technology is not in place
1 do not pay attention to prevent disease in advance
From the beginning of the bean rack to the pod-forming period, the problem of the dead vine has been plagued by the vegetable growers. From the beginning of flowering and pod-forming, the medicament for controlling the pods has not stopped, and the effect is not very good, except for the above. In addition to the reasons, not paying attention to prevention in advance is the biggest reason, because the dead vines are mainly root rot and blight, once the disease is unable to cure, can only be sprayed to control and keep the disease has not yet occurred, and the vegetable farmers find the disease It is often the "late cancer". In fact, as long as the nursery or transplanting, early in the early stages of the disease to pay attention to timely drug prevention, such as carbendazim or thiophanate or sodium sulfonate and other conventional agents, plus other management measures, it is not difficult to solve the dead vine questionable.
2 do not pay attention to medication
Because the vegetable farmers are resistant to disease and pest control, the application is like taking a bath for the bean rack, and the medicine from the top to the bottom is DC. In fact, this method wastes medication, the cost increases, and the beans produced are difficult to meet the pollution-free requirements. It is recommended that the vegetable farmer choose a suitable spray machine, change the spray in time, increase the atomization efficiency, and improve the spray efficiency.
3 do not pay attention to medication timing
For example, pea pods, larvae are mainly based on scorpion eater, the principle of prevention and control is to cure flowers and treat pods, and to treat the flowers on the ground. When controlling, it is necessary to master the appropriate period of medication. Otherwise, the effect is poor or has no effect. Generally, when the larva is at the age of two or three, it is sprayed. The time is most suitable at 8~10 o'clock in the evening and 5~6 o'clock in the morning. At this time, the drug can be used for more than 90%.
The above is the reason and solution for the low yield of beans. In fact, it is actually a problem of improper management. Farmers must be scientifically managed when planting beans. Do not affect the yield and quality of beans because of improper management. I hope the above content is correct. Farmers can help.
