When farmers grow soybeans, they often have pods that are not full or empty, what is the reason? How

Soybean is a major food crop in China, with a large planting area. The nutritional value of soybeans is very high and is welcomed by many people. However, although the soybean planting technique is simple, the yield is relatively high.

However, during the planting process, the phenomenon of empty pods often occurs, which seriously affects its yield. So what causes empty pods in soybeans? Let's take a look at it below!

When growing soybeans, the choice of variety is very important. If the breed is not selected properly, it is very easy to have empty pods. For example, some varieties with a high pod setting rate and many grains will have a relatively high empty pod rate.

Moreover, different varieties will have different requirements for the growing environment and climate. Therefore, if the variety is not adapted to the local environment, it is prone to a large number of grains. Especially for some late-maturing varieties, if the temperature is lower during the drum time, it will cause the drum speed to decrease, resulting in empty pods.

The climatic environment has a great impact on the growth of soybeans. During the growth period of soybeans, if they encounter drought or waterlogging, their empty pod rate will be increased. During the flowering pods of soybeans, the impact of waterlogging is much greater than that of drought, and not only will empty pods, but also cause them to lodging.

In addition, if the soybean is sown too late due to drought at the time of sowing, the growth period of the soybean will be shortened and the pod will be empty. In the later stages of growth, if the temperature is too low, the soybean will continue to be filled, which will also cause empty pods. High temperatures can cause soybeans to bloom but not to bear fruit.

After the soybean enters the flowering stage, the demand for nutrients will increase greatly. It will consume a lot of nutrients, so in the late stage of soybean growth, we should pay attention to fertilization and increase the amount of fertilizer. Many people are prone to malnutrition when soybeans are interplanted, if they do not apply basal fertilizer and do not top dressing, they are prone to malnutrition when soybeans are in full bloom.

The leaves will also have various undesirable phenomena such as yellow leaves and short plants due to lack of nutrition. Weak pods that lead to late pods or flower clusters at the same node are generally more common in varieties with poor soil fertility and large number of flower pods.

Soybeans need a lot of nutrients during the growth process. Many people will ignore the supplementation of some trace elements, such as boron, molybdenum, etc., and the deficiency of these two elements is also the main cause of soybean empty pods. Boron and molybdenum are also indispensable trace elements in the growth of soybean, which is directly related to the podding of soybean.

If there is less boron-molybdenum in the soil and there is no topdressing, it will definitely lead to an increase in the empty pod rate of soybeans. Especially in soybeans with heavy crops, the empty pod rate will be higher every year.

The soybean varieties selected were not particularly good, they were not planted in the right way, they did not do a good job in field management after planting, did not apply base fertilizer in time, did not replenish enough water, and did not have enough sunlight. Before planting, soybean seeds are soaked in water, nutrient solution is sprayed, and field management is done.

If the soybean milk is not full, it is likely to be caused by the lack of water during the growing season, and scientific field management, fertilization and watering are required during the growing period.

It's usually because it's not getting enough sunlight, so I think it should be planted in a greenhouse. Or find a place with better lighting.

In recent years, in soybean production, farmers have constantly reflected: soybean stems and leaves grow luxuriantly, the leaf color is dark green, but there are few flowers, few pods, or even basically no pods; Some also have flower pods, but empty pods and dead grains appear. In some cases, the plants mature late, the growth period is delayed, and the grains cannot mature on time.

Therefore, soybeans do not set fruit and cannot be harvested normally, which seriously affects soybean production and brings huge economic losses to farmers.

<> physiological characteristics of soybeans. Soybeans are a short-day crop. In general, early-maturing varieties are not sensitive to light and do not have strict requirements for short-day conditions.

The reason for the empty pods and non-pods of soybeans is that soybeans are sensitive to temperature and reproductive elements, so trace elements such as calcium, zinc, boron, and molybdenum should be supplemented. The suitable temperature for soybean flowering is 23 -28 and the relative humidity in the field is 70-90%. (In recent years, the temperature in the Huang-Huai-Hai region has generally increased, and the high temperature is not conducive to soybean flowering).

Soybean flowers are affected by high temperatures, pollen is easy to dry, pollination is easy to fail, resulting in only flowering without pods, or empty pods. If the temperature is kept at 33 40 for a long time, the soybean yield can be reduced by 30 to 50%. After soybean flowering, nutrient consumption increases, if the fertilizer and water ** are insufficient, soybean is prone to nutrient deficiency after flowering, which eventually leads to only flowering without pods, or only pods without fruit.

The imbalance of soil nutrient elements in the soil lacks boron, molybdenum and other elements, which will also lead to empty pods and immature seeds, flowers and fruits in soybeans. Especially in soybean crops, the empty stalk rate per plant is increasing year by year. In the case of partial application of nitrogen fertilizer, it will cause shade in the field, over-growth of plants, scarcity of flower pods, and the formation of empty pods and immature seeds.

It is very important to choose soybeans before planting, be sure to choose high-quality seeds, and then pay attention to watering and fertilizing soybeans, and properly supplement them with nutrients to remove insects, so that the airdrop rate of soybeans planted is relatively low, and at the same time, we must also weed them, so as not to dilute their nutrients by weeds.

We should choose a suitable place for growth and development, followed by frequent crop rotation in life, and some formula base fertilizer should be selected. Fine sowing should also be done. To water frequently, fertilize frequently, and be a short-day crop.

First of all, when selecting varieties, we should choose excellent varieties, and should rotate crops, should apply enough bottom material, can use some phosphorus and potassium fertilizers, can use herbicides, can control pests and diseases.

1. Nutrient imbalance. The stage of soybean flower and pod drop is the period when the nutrients are the highest, and if the nutrients are insufficient, it will cause the flower pods to fall off. If excessive nitrogen fertilizer is applied, it not only inhibits nitrogen fixation, but also often causes soybean overnutrition, plant growth, canopy closure and lodging, resulting in flower pod shedding.

2. The density is unreasonable. If the planting density is too large, the plants are crowded, the competition for water and nutrients between plants is fierce, the ontogeny is hindered, the internodes are lengthened, the growth is weak, the ridges are sealed too early, and the branches and leaves are shady; High humidity and low light deteriorate the light conditions in the lower part of the plant, resulting in less chlorophyll content in the leaves, gradual yellowing, and reduced nutrient accumulation, resulting in flower pod shedding.

It should be that the variety is not good or there is more rain for a long time, the sun is not strong enough, and the temperature is relatively low, which will also lead to this result.

The basic reason for soybean pods is the characteristics of soybeans themselves, which may be due to the poor soil and insufficient nutrients.

The planting density of the plant is too large, resulting in insufficient ventilation and light, reduced photosynthetic production, physiological disorders within the plant, nutrient competition between plants, and insufficient nutrients, resulting in pod dropping.

It may be that there is a lack of water, and when soybeans don't get enough nutrients, their flowers will fall.

The suitable temperature for soybean flowering is 25 28 and the suitable relative humidity is 70 90%. If the temperature is kept above 33 for a long time, the soybean pollen grains will shrink, resulting in poor pollination and fertilization. If soybeans.

If the high temperature and drought continue during the flowering and podding period, the soybean will not bloom or have a small number of flowers, or it will not be fertilized normally, resulting in unfruitful flowers. Too much nitrogen fertilizer, too much vegetative growth, farmers complain.

<> poor ventilation and high pollination temperatures can affect soybean podding. High temperatures, droughts, pests and diseases are the main reasons for not forming pods. The main reasons are that high temperature and drought lead to pollen miscarriage, high density and blindness lead to poor pollination, phosphorus and potassium deficiency fertilizer vegetative growth and reproductive growth ratio is out of balance, boron deficiency leads to flowers but not fruit.

The main reasons for soybean not forming pods are high temperature and drought, pesticide hazards, and insect pests. The lack of pod-setting in soybeans is due to a deficiency of boron**. The control method is to spray borax fertilizer at the early flowering stage of soybeans, with 50 grams of boric acid (one or two) mu, mixed with 30 kg of water and sprayed on the foliar surface.

Be careful not to overdose, which can cause boron poisoning.

One is that the prunes are too close, resulting in too fast growth, and the other is boron deficiency. Soybean does not set pods and is related to variety, density, high temperature and drought, pest and disease hazards, as well as water and fertilizer management. Apply organic fertilizer and phosphorus and potassium fertilizer, sow seeds at the appropriate time, plant reasonably densely, strengthen fertilizer and water management, and prevent and control pests and diseases in a timely manner.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you guys have any ideas, you can let us know in the comments below.

It may be that the nutrients are too large and the bushes are left behind or the water is very much, and the cherry blossoms may be at a relatively low temperature, and the selected seeds are not particularly good, which may cause the soybeans not to set podders.

This is due to the lack of water, and the severe water shortage will occur during flowering, which is related to the variety and the management of the water section.

Caused by pests and diseases, the soil is not fertile, the seed germination rate is not high, the warmth is not paid attention to, and the seeds are not watered in time.

In the process of soybean planting, there will be some empty pods, which will affect the overall yield of soybeans, and the soybean empty box is mainly because there is no good variety, when the variety is not selected, it will be easy to cause soybean empty pods, and when the varieties are not suitable for the local climate and environment, there may be grain shedding, and finally empty pods. In the process of soybean planting, the influence of climate is also very important, if there is drought or excessive precipitation, it is possible to increase the empty pod rate of soybeans, and if soybeans happen to encounter disasters, the impact will be even greater. Therefore, if you want to grow high-yield and high-quality soybeans, you need to choose suitable varieties, choose varieties according to the actual local conditions, and then carry out reasonable dense planting according to the fertility of the soil, and do a good job in water management and nutrient management during the soybean flowering period, as well as the management of pests and diseases.

During the soybean planting period, you can appropriately increase organic fertilizer and phosphorus and potassium fertilizer, if you use nitrogen fertilizer alone, it is very easy to cause crazy growth, and although the pods grow, but it is not true, when the seedlings can be appropriately added a certain amount of organic fertilizer and compound fertilizer. At the same time, foliar fertilizer can be sprayed appropriately in the early stage of soybean flowering, and the spraying of foliar fertilizer should also be mainly sprayed on the back of the leaves.

Weeding during soybean planting is actually very critical, do not blindly weed, especially at the seedling stage, you can spray herbicides to control weeds, the effect will be more, because there will be a lot of weeds in the soybean growth process, these weeds will absorb the nutrients in the soybean soil to a certain extent, resulting in a reduction in soybean yield. Therefore, it is necessary to use herbicides reasonably according to different grass varieties in the field to reduce the impact of weeds in soybeans.

Finally, if you plant soybeans, you need to choose the corresponding method according to the specific growth of your own soybeans, so as to ensure that the soybean yield is increased and the yield is high.

It could be because the soybeans are experiencing root wilting, too much fertilizer, too little watering, a lack of nutrients, or it may be due to rotting in the roots. If you want to plant high-yield and high-quality soybeans, then you must choose the soil is more fertile and broad land when planting, you must use farmhouse fertilizer when fertilizing, do not use fertilizer bought outside, and often water the plants, but also to prevent the occurrence of pests and diseases, if there are small insects, then you must spray insecticides in time.

It may be that the soybean variety is not good, the soybean encounters a flood or drought when it blooms, the nutrition cannot keep up with it when it blooms, and there may be an empty pod when there is a pest. To choose a good variety of soybeans, you should choose soil with better characteristics, you should water and fertilize in advance before planting soybeans, the soil should be exposed to the sun, and you should apply more fertilizer and water more after soybeans bloom, so as to grow high-quality soybeans.
