What is the reason why soybeans have pods and no beans?

1. The reason why soybeans have pods but no substance.

1. Improper selection of varieties.

Generally speaking, the late-maturing varieties are selected, and the temperature is already low at the soybean drum stage, which seriously affects the grain drum speed, so it induces pods but not substance.

2. * The ratio of soil nutrients is out of balance.

Boron is an important trace element that promotes the formation and growth of soybean pods.

Boron deficiency can induce soybean pods to be indifferent; In addition, excessive nitrogen fertilizer, shade in the field, tall plants, long internodes, excessive vegetative growth, sparse flower pods, the formation of empty pods, semi-deflated pods, and the maturity period is delayed. It is especially severe in years with high rainfall and insufficient sunshine.

3. Poor field management.

Heavy cropping, soil compaction, excessive nitrogen fertilizer, weak grass seedlings, and excessive density will affect the ventilation and light transmission of soybean plants, thereby weakening photosynthesis.

Leads to pods and inauthenticity.

4. Adverse climatic conditions.

For example, there is more rain during the soybean growth period, or long-term drought, serious lack of water, high or low temperature will reduce soybean photosynthesis and respiration.

Increase, less manufacturing substances, more consuming substances, resulting in soybean pods and inauthenticity.

5. Pest and disease hazards.

In summer and autumn, the occurrence of viral diseases in soybean causes the leaves to shrink and the young pods to be deformed, and the soybean heartworm damage causes the insect eyes to be empty and seedless.

Second, soybeans have pods and no precautionary measures.

1. Choose suitable varieties.

According to the local climate characteristics and planting habits, select varieties suitable for local planting, drought and flood resistance, lodging resistance and disease resistance, high-quality medium and early maturity and low maturity for planting.

2. Arrange stubble reasonably to avoid heavy planting.

Reasonable planting structure can effectively reduce the occurrence of pests and diseases, avoid the single consumption of soil nutrients, maintain balance and sustainable use of soil resources. Under this principle, the stubble should be reasonably arranged, the crop rotation system should be adopted, and the stubble should not be replanted as much as possible, so as to reduce the pod and not achieve the occurrence of elephants.

3. Sow seeds at the right time.

Summer soybeans should be sown at the right time, sowing too early will lead to early flowering, and it will also cause old seedlings and crazy seedlings. The suitable sowing date for summer soybeans is generally from June 5 to 15, and if it is a late-maturing variety, it should be sown after June 20.

4. Scientific fertilization to maintain nutritional balance.

Follow the principle of "suitable nitrogen fertilizer, increased organic fertilizer, combined application of phosphorus, potassium fertilizer and micro fertilizer", scientific fertilization, and maintain nutritional balance. If sufficient fertilizer and water cause plant growth, the foliar spray should be applied at the early flowering stage, which can reduce the plant height, prevent the flower pod from falling off, and reduce the empty stubble rate.

In addition, foliar fertilizer can be sprayed skillfully at the flowering and grain bulging stage, which can promote flowering and podding and promote the fullness of grains. Kilograms of urea or potassium dihydrogen phosphate are available.

kg + 100 grams of borax, and then mixed with 60 kg of water for foliar spraying, the yield increase effect is obvious.

5. Reasonable irrigation, timely drought prevention and drainage.

Before soybean sowing, if it is dry and early moisture.

When the time is poor, it should be watered in time to ensure the emergence rate, in the growing period if it is dry early, the soil moisture is insufficient, it should be watered in time to prevent drought, so as to meet the demand for water in soybeans, which can reduce the saffle. In case of long-term.

Soybeans only grow pods but do not produce seeds may be related to high temperatures, excessive nitrogen fertilizer, pests and diseases, drought, improper use of pesticides, etc. Persistent high temperatures can cause soybean pollen grains to dry up, resulting in poor pollination and fertilization. Too much nitrogen fertilizer will cause excess nutrients and affect the reproductive growth of soybeans.

Soybeans are infested with insects, which will empty the pods. Drought during the flowering and podding period is not conducive to soybean flowering and fruiting.

Boron deficiency, bugs, and drought during the flowering period of soybean can cause soybean flowering and unfruiting. Solubor plus bifenthrin plus brassinin can be sprayed to promote flower bud differentiation and increase pod setting rate.

There are no beans in the soybean pods, because of the problem of seeds, because of the problem of drought, because of the problem of pests and diseases. It also has to do with the soil problem, and it has to do with the high temperature.

Generally speaking, the absence of beans in soybean pods may be a problem with the seeds, or it may be too hot, malnourished, or too dry, and suffering from a series of pests and diseases.

The first may be that the beans are not planted well, and the second is that the soil nutrients are not balanced, the pollen is not fully fertilized, the field management is insufficient, and the water and fertilizer are not enough.

Hello! Internal reasons for the lack of soybean pods: variety differences, improper introduction; External factors: temperature, rainfall or drought during flowering; Excessive density in cultivation, excessive fertilization, heavy stubble, pests and diseases, etc.

Previously we had a plot with the same management of three sowing periods, variety, density, and the lowest yield in the middle sowing period. The reason for this is that the pollination is seriously affected by high temperatures and rainfall during the flowering period. It has also been reported that soybeans only bloom but do not set pods, and high temperatures and rainfall are also one of the reasons.

As a result, soybean pods are few and not real. FYI!

Hello Soybeans are low- and medium-yield crops, which are greatly affected by the climate during the growth process, and are affected by traditional management. It coincides with the rain this year, and it is easier to grow vigorously when it rains before the seat, resulting in excessive vegetative growth and hindered reproductive growth.

Prevention methods: 1. The first flowering period of the buds: appropriate control of the vigor and multi-effect.

15 grams of azole mixed with 15 kg of water can be sprayed.

2. Pod period of full flowering festival: per mu.

Apply 15 15 15 balanced fertilizer 20 kg.

3. Pod drumming stage: combined with pest control at the same time.

Add 50 grams of potassium dihydrogen phosphate per mu, 5 7 days a.

times, 2 times in a row 3 times, the yield will be higher than that of traditional tubes.

Rationale has improved!

Hope it helps
