The growth process of soybeans, the growth process of beans

The growth process of soybean can be divided into six stages: germination stage, seedling stage, flower bud differentiation stage, flowering and pod-setting stage, grain drumming stage, and maturity stage.

Germination: Soybeans can germinate in about a week after planting, and then the leaves will begin to stretch. Seedling stage:

Before soybean grows flower buds, the stems and leaves still need to continue to grow, at this time it needs a lot of nutrients and water to promote the growth of seedlings, and it generally takes about a month to enter the flower bud differentiation period.

Flower bud differentiation stage: When soybean enters the flower bud differentiation stage, the plant will grow the original body of the flower bud, and then grow buds and flower buds, and the organs of the flower buds will gradually grow. Flowering and pod-setting period:

Soybeans bloom in the morning at this stage, and the flowering period usually lasts for about a week. During this time, soybeans need more nutrients and water, and need timely watering and fertilization. Drum Stage:

At the time of the grain bulging stage, the beans in the soybean pod will gradually expand.

The beans grow slowly about 10 days after flowering, but after a month, the beans will grow rapidly. Maturity: After the leaves of the plant turn yellow and fall off, the moisture content of the beans in the pods will also begin to decrease, and the soybeans will gradually mature.

The growth process of soybean is divided into six stages: germination period, seedling stage, seedling stage, flower bud differentiation period, flowering and poding period, drum grain stage, maturity period, and it takes about 180 days from seedling emergence to maturity, in addition, soybean is planted in November in autumn every year, at this time, the seeds with full particles are selected, and after their germination treatment, they are evenly sown on the soil surface.

The growth process of soybean is divided into six stages: germination stage, seedling stage, seedling stage, flower bud differentiation stage, flowering and pod-setting stage, grain drumming stage and maturity stage.

It takes 180 days for soybeans to mature from seedlings to maturity, but due to the different climatic environments in various places and the differences in the varieties planted, the specific growth cycle of the plant is slightly different, in addition, soybeans are generally planted in November of each autumn, and can be harvested in March and April of the following year.

Before planting soybeans, the seeds need to be germinated to shorten the germination time of the plant, then the seeds are evenly spread on the soil surface, and the seeds are covered with a layer of fine soil, then watered to keep the soil moist, and if the weather temperature is low, a layer of mulch film is covered on top of the soil.

In the process of maintaining soybeans, it is necessary to carry out weeding in time to promote the growth and development of plants, and after soybeans enter the flowering period, spray potassium dihydrogen phosphate on the leaves two to three times to improve the yield of plants.

A few days before the process, when the teacher gave us homework in Chinese class, I went home to soak the beans, observed its growth process and recorded it. When I got home, I took out a small cup and asked my grandmother for some soybeans. I first put the soybeans into the cup one by one, and add the water, so that the water is just over the soybeans.

The soybeans immediately sank as if they were in dire need of water.

The next morning, I just woke up and couldn't wait to run to see the beans. I found that the beans were a little bigger than when I first soaked them, like a little baby drinking enough water.

On the third day, I noticed that the beans were bigger than the next day, so I quickly fished them out and put them in the prepared wet towel and bathed them once a day to make the "little baby" comfortable.

On the fourth day, the beans cracked a small crack, but the sprouts had not yet grown, so I waited very anxiously.

On the fifth day, the sprouts grew, and it was like a newborn baby poking out a little bit of its head to see the world, which was so cute. I keep watering the beans every day, hoping that the sprouts will grow better and stronger, and that they will grow many tiny roots.

On the tenth day, the sprouts were already two inches tall...

Today I had dinner at my grandmother's house, and I hurried home, thinking about my little beans!

Today I noticed that the color of the water in which the beans are soaked is darker, as dark as the color of red wine, but the color of the beans has not changed much, which is really interesting.

Some beans have a small crack in the skin of one third of the way, and a small bud lies inside, which is very cute, like a shy little girl, throwing herself into her mother's arms and secretly looking out. Some beans only have cracks and no small shoots. Some of the beans didn't even crack the skin, they were still hard, and they seemed to be demonstrating against me

I refuse to grow up! "This little lazy worm.

There are so many changes in beans, today like this, tomorrow like that, it really dazzles me.

On the fourth day, my beans all turned into a number seven. The sprouts grew longer and longer, and the longer they went. I measured it with a ruler and it was 4 centimeters long! I also changed the water for the sprouts and covered them with wet gauze again, just like yesterday.

Through the matter of soaking bean sprouts, I understand that in life, as long as we pay attention to observation, there will be discoveries.

1. Is soybean a long-day or short-day plant?

Soybean is a short-day plant, and short-day plant is a plant whose sunshine time is shorter than a certain critical day length before flower buds can be formed, or it is a plant that promotes the formation of flower buds. Soybean is a plant of the genus Soybeanaceae, which is native to China and is now cultivated in many parts of the world. Soybeans are an important food crop.

It has a long history of cultivating air-burning in China. In nature, in addition to soybeans are short-day plants, which also include rice and morning glory.

Chrysanthemum, Xanthus.

etc., they all belong to the short-day plants.

2. Growth habits of soybeans.

Soybeans like to be warm, the temperature suitable for seed growth is about 15-20, when the temperature is 10-12, it will germinate, the temperature suitable for flowering and pod-setting is about 20-28, when the temperature is low, the speed of pod-setting will be slow, when the temperature is lower than 14, it will not bloom. It requires more water during the growing period, and at the time of flowering, the water content in the soil.

It needs to be kept at 70%-80%, otherwise the flower buds are easy to fall off.

3. What are the types of soybeans?

According to the color and grain shape of soybeans, Dadou Huixu beans can be divided into yellow soybeans, green soybeans, black soybeans, other soybeans, and feed beans. Yellow soybeans are a relatively common variety, and they are made into various soy products. Green soybeans are soybeans with a greenish seed coat, black soybeans are what people call black soybeans, and forage beans are straw beans.

The soybean growth process is divided into five stages: germination stage, seedling stage, flowering and pod-setting stage, grain drum stage, and maturity stage.

1. Germination period.

The germination period is the first growth stage of soybeans, which refers to the period from the seed sowing to the first true leaf, generally about 4 6 days, and the specific time varies depending on the variety, sowing, climate, management, etc., for example, the seed germination before sowing can be 2 3 days in advance.

2. Seedling stage.

The seedling stage is the second growth stage of soybean, which refers to the period from the first true leaf of soybean seedlings to the period before the flower buds grow, generally about 20 25 days, accounting for the entire growth period of 1 5, during this period of soybean to vegetative growth, need to provide sufficient nutrients to speed up plant growth.

3. Flowering and pod-setting stage.

The flower bud differentiation stage is the third growth stage of soybeans, which refers to the period from soybean flower buds to pods, generally about 30 40 days, during which vegetative growth and reproductive growth are carried out at the same time, soybeans need a lot of nutrients at this time, and nitrogen, phosphorus and potassium fertilizers need to be applied every 10 15 days.

4. Drum grain stage.

The drumming stage is the fourth growth stage of soybeans, which refers to the period from the growth of soybeans to the completion of pods, generally about 15 20 days, during which soybeans gradually change from vegetative growth to reproductive growth, and the seeds begin to accumulate nutrients, and the seed water content is as high as 90% after the end of the drumming period.

5. Maturity period.

The maturity period is the fifth growth stage of soybeans, which refers to the period when the pods complete the expansion to full maturity, generally about 25 to 30 days, during which the soybean is mainly reproductive growth, the seed moisture content gradually decreases and presents the inherent physical form of the variety, and there is a slight sound when shaking the pod.

Introduction to soybeans

Soybean (scientific name: glycine max (linn.).) merr.

It is an annual herb of the genus Soybeanaceae in the legume family, 30-90 cm tall. The protein content of soybeans is 35% to 40%. The stems are stout, erect, densely covered with long brown bristles.

Leaves usually have 3 leaflets; The leaves are veined, pubescent with yellow; petioles 2-20 cm long; leaflets broadly ovate, papery; The racemes are short with few flowers and long with many flowers.

There are six parts in the growth process of soybean, which are seedling stage, seedling stage, flower bud differentiation stage, flowering and podding stage, grain drum stage, and maturity stage. The demand for water and fertilizer in the seedling stage of soybean is very high, at this time, the planting should be watered and fertilized in time, and the stage when the soybean just grows flowers to the flowers fall off to form pods is the flowering and pod-setting stage.

Soybeans, also known as soybeans, belong to the legume family, native to our country, and are one of the common crops in life. The soybean growth process is divided into six parts: seed germination and emergence stage, seedling stage, flower bud differentiation stage, flowering and podding stage, drum and grain stage, and maturity stage.

When planted, soybeans will emerge after 4 to 6 days of sowing, and the emergence of leaves from the soil is called the seedling stage, and the middle stage from the seedling stage to the flower bud differentiation is the seedling stage. When the soybean seedling stage is young, the young stem continues to grow upward, and its underground root system grows very quickly at this time, and the underground root will form a nodule in about half a month.

Soybean has a high demand for water and fertilizer in the seedling stage, so the planting should be watered and fertilized in time to supplement nutrients, and the seedling stage usually lasts for about 25 days. The flower bud differentiation stage, also known as the branching stage, is a stage in which soybeans grow leaves quickly, and in the later stage, when the flower buds are mature, soybeans will bloom and set pods.

The flowering and pod-setting stage is the stage from the time the soybean grows flowers to the time when the flowers wither to form pods, when the ovules of soybeans will gradually expand after fertilization, and then form small soft green pods. The grain drumming stage is an important period for the formation of soybeans, at this time, the plants should be watered in time, and the soybean leaves will turn yellow before the soybean maturity stage.
