What are the solutions for soybean plants that flower but do not set pods?
Soybean is a common crop, widely used in soy products and dairy products, with significant economic benefits, but during cultivation it often shows flowering without fruiting, that is, flowers without pods. This affects farmers' income and is a real headache, so what causes soybean plants to flower without setting pods? Let's take a look at the solutions for soybean plants that flower but do not set pods with Qinnong Web.
1. Variety reasons
Soybean is a common crop with a long cultivation history in our country. After years of breeding and cultivation, there are many varieties. If a variety unsuitable for the local growing environment is chosen during planting, it will cause a phenomenon of "not adapting to the local conditions", and symptoms of flowering without setting pods may appear.
Solution: When choosing a variety, identify the soybean brand clearly and select a variety suitable for local planting, growth and development.
2. Improper sowing time
The sowing time of soybean is extremely important. If sowing is too early or too late, missing the best sowing time, and the climate changes, when high temperatures or a high-temperature environment are encountered during growth, soybean photosynthesis weakens while respiration strengthens, causing excessive nutrient consumption, which is unfavorable for soybean flowering and pod setting.
Solution: Master the correct sowing time. Soybean sowing time is divided into spring sowing and summer sowing. Spring sowing is around Qingming, while summer sowing is carried out after the wheat harvest. The climate varies by region, so sowing also differs slightly, but the overall difference is not large.
3. Improper fertilization and lack of elements
Some farmers, in order to promote rapid soybean growth during planting, apply excessive nitrogen fertilizer during the growing period, resulting in excessive nutrition, spindly plant growth, and fertilization that is too one-sided, with other trace elements lacking. The soil becomes compacted and cloddy, with poor permeability, which is unfavorable for flowering and pod setting. In most cases, boron deficiency can also induce the phenomenon of flowering without setting pods.
Solution: Pay attention to methods when fertilizing. Do not use a single fertilizer only; balance various fertilizers. In particular, prevent one-sided application of nitrogen fertilizer, and be sure to apply phosphorus and potassium fertilizers together. It is recommended to focus on base fertilizer, with organic fertilizer or compound fertilizer applied as topdressing later, to maintain the supply of elements.
4. Continuous cropping
Soybean is a crop that dislikes continuous cropping and repeated cropping. Some farmers, for convenience, plant it on the same field year after year. According to research, the disease incidence rate of plots planted continuously with soybean for two years reaches 50%, while for more than three years the incidence rate is basically 100%, and the severity of disease is about 80% higher than usual.
Solution: Implement reasonable crop rotation, rotating for 1-2 years with other non-legume crops, such as vegetables and melon and fruit crops. This can improve soybean yield and quality.
The above are the solutions for soybean plants that flower but do not set pods brought to you by Qinnong Web. In addition, poor soil permeability and drainage can also cause symptoms of soybean plants flowering without setting pods. The issue of soybean plants flowering but not setting pods is introduced here, and we hope it can help you.
