How is broccoli grown? Broccoli growth cycle

The whole reproductive process of broccoli can be divided into the following periods.

1) Seedling stage.

From sowing to planting, i.e. from sowing to 5 to 6 true leaves.

Seedlings are 30 to 40 days old.

2) Vegetative growth period.

From colonization to the appearance of flower bulbs, it takes about 60-90 days. This period is the growth of leaf clusters and inflorescences.

In the differentiation stage, sufficient nutrients are needed to promote the vigorous growth of leaf clusters, accumulate more assimilated substances, and lay the foundation for the development of flower bulbs.

3) Flower bulb growth period.

It generally takes 15 to 20 days from the appearance of flower bulbs to harvesting. The period after the appearance of flower bulbs, flower buds.

and flower stems continue to develop and grow, becoming flower balls composed of several short, fleshy flower stems and flower buds, which meet the standards of commercial harvesting.

4) Flowering and seeding stage.

It takes about 90 days from the time the buds swell and bloom to the seeds are harvested.

Broccoli is grown from seeds, and it can also be cultivated into small seedlings, which is the same as our ordinary cauliflower.

The growth and development of broccoli goes through five stages: germination stage, seedling stage, rosette stage, flower bulb formation stage, and flowering and fruiting stage. The germination stage, seedling stage and rosette stage are the vegetative growth periods of plants. During this period, the number of leaves and height of the plant increased, and at the same time, the vernalization process was completed by sensing external changes.

When the rosette stage ends, flower bulbs begin to appear at the top of the main stem, and the plant enters the reproductive growth stage, and the flower bulbs gradually develop. When the external conditions are suitable, the flower bulbs can bloom and bear fruit.

Germination period From the germination stage of seeds to the cotyledons and the first true leaf dew, it takes 7 to 10 days. The length of germination time is main.

2.Seedling stage The broccoli seedling stage is from the first true leaf to 5 6 true leaves, and the seedling stage is when it reaches the "cluster". In winter.

3.Vegetative growth period From the first ring of leaves to the beginning of the flower bulbs is the vegetative growth period. The length of time varies depending on the variety and cultivation season.

4.The rosette stage of broccoli is from 5 to 6 true leaves to the length of the plant with 17 20 leaves and ridges, and the length of time varies depending on the variety and.

There are five stages of broccoli growth and development: germination stage, seedling stage, lotus sitting stage, flower bulb formation stage and flowering stone stage. Hope it helps, thank you.

Broccoli is native to the coastal regions of the eastern Mediterranean. And it has been spread to our country for a long time. At present, it is cultivated in both the north and the south of the country, and it has naturally become one of the most commonly eaten vegetables, which is rich in nutrients and contains protein, sugar, fat, carotene, etc., so it has always been known as the crown of vegetables.

So if you want to grow it, how long does it take for broccoli to grow? According to very experienced old farmers, broccoli takes 80 to 90 days, or three months, from planting to harvesting.

Broccoli is usually planted in the autumn of each year, and after a whole cold winter, it can be harvested and sold in the spring of the following year.

And the planting environment and conditions it requires are actually not very demanding. In terms of light, as long as you can ensure sufficient sunlight. If you absorb more sunlight, the plant will be able to grow strong and form a strong nutrient body, which is conducive to photosynthesis and nutrient accumulation, making the flower bulb compact and dense.

In terms of temperature, the temperature conditions required throughout the growth process are also different. The temperature at the germination stage is 20 to 25 degrees, and at the seedling stage it is 15 to 20 degrees, and the suitable temperature for the rosette stage is about 20 degrees. Broccoli has a very large need for water throughout the growth process, especially during the vigorous growth of leaves and the formation of flower bulbs.

However, if there is too much water, the soil moisture will be too high, which will cause black rot, black spot and so on.

Due to the high temperature, broccoli is difficult to cultivate and has a relatively poor degree of freshness. It is usually recommended to sow broccoli in early April so that the broccoli can ripen in the summer. However, due to regional differences, the choice of time has a great impact on broccoli, and whether the right time is chosen also affects the quality of broccoli.

Generally speaking, the ideal time for planting is in early April, when there is plenty of precipitation and moderate temperatures, which is just in line with the warm and humid climate, which is very conducive to the growth of broccoli. Broccoli can basically be harvested in late May. When does broccoli ripen.

It is usually recommended that you raise seedlings in an insulated area such as a greenhouse and then move to outdoor planting in March. Since the seedling and growth period of spring sowing come when the temperature is very low, some early-maturing varieties will bloom at low temperatures, which affects the yield and quality of flower bulbs. Therefore, early-maturing varieties that are cold-resistant, not easy to break out, and early differentiation should also be selected, and generally mature at the end of April.

Of course, due to different geographical locations, the growing period of broccoli is also different, depending on the actual local situation. The broccoli harvest takes 80 to 90 days, which is 3 months. Broccoli is grown in the fall, then cold-grown throughout the year, harvested in the spring, and then marketed.

The cost and profit of broccoli planting can be sold for about 5 yuan for about one kilogram of broccoli, and at least about 3,000 kilograms of broccoli per acre, you can earn about 2,500 yuan. Planting prospects remain positive. Broccoli planting technology points in cultivating and weeding:

In the early stage of broccoli growth, weeding should be carried out at the same time as top dressing, which can improve the nutrient uptake efficiency of broccoli roots. Timely top dressing: When broccoli grows, apply more nitrogen fertilizer, do not apply too much phosphorus and potassium fertilizer, otherwise it will sprout early, and some trace elements should be supplemented.

Water management: The soil should be moist when broccoli grows, and the soil moisture content of broccoli should be controlled at 75% when it enters the flower bulb formation stage.

Pest control: Broccoli is easy to cause other pests and diseases, and field management should be strengthened to reduce the incidence. The planting environment and conditions it requires are not very demanding. In terms of light, as long as sufficient sunlight can be ensured.

If more sunlight is absorbed, the plant can grow healthily and form a strong nutrient body, which is conducive to photosynthesis and nutrient accumulation, making the flower bulbs dense and dense. In terms of temperature, the temperature conditions required throughout the growing process are different. The temperature at germination stage is 20-25, the temperature at seedling stage is 15-20, and the suitable temperature at rosette stage is about 20.

Throughout the growth of broccoli, there is a great need for water, especially for the vigorous growth of leaves and the formation of bulbs. In the event of a short-term drought, yields are reduced. But if there is too much moisture, the soil moisture will be too high, causing black rot, black spots, etc.

There are seedling stage, vegetative growth cycle, flower bulb growth cycle, and flowering and fruiting growth cycle, which are mainly divided into these four cycle stages.

30 days of seedling stage, 2-3 months of growth period, half a month of flower bulb stage, three months of fruiting period, this is its growth cycle.

There are 4 cycles, the first is the seedling stage, the second is the growth period, the third is the flower bulb growth stage, and the fourth is the fruiting stage.

1) Seedling stage.

From sowing to planting, that is, from sowing to 5 to 6 true leaves, the seedling age is 30 to 40 days.

2) Vegetative growth period.

From colonization to the appearance of flower bulbs, it takes about 60-90 days. This period is the growth of leaf clusters and the differentiation of inflorescences, which require sufficient nutrients to promote the vigorous growth of leaf clusters, accumulate more assimilated substances, and lay the foundation for the development of flower bulbs.

1. The seedling stage is from sowing to planting, that is, from sowing to 5 6 true leaves, and the seedling age is 30 to 40 days.

2. The vegetative growth period takes about 60 to 90 days from planting to the appearance of flower bulbs. This period is the growth of leaf clusters and the differentiation of inflorescences, and sufficient nutrients are needed to promote the vigorous growth of leaf clusters, accumulate more assimilated substances, and lay the foundation for the development of flower bulbs.

3. It takes 15 to 20 days from the appearance of flower bulbs to the harvesting of flower bulbs. After the flower bulb appeared during this period, the flower buds and flower stems continued to develop and grow, and became a flower bulb composed of several short fleshy flower stems and flower buds, which reached the standard of commercial harvesting.

4. The flowering and seeding period takes about 90 days from the expansion of flower buds to the harvest of seeds.

Broccoli grows in the fields.

Broccoli fertility process:

1) Seedling stage. From sowing to planting, that is, from sowing to five to six true leaves, the seedling age is 30 to 40 days.

2) Vegetative growth period. It takes about 60 to 90 days from planting to flower bulbs. At this stage, the growth of leaf clusters and the differentiation of inflorescences require sufficient nutrients to promote the vigorous growth of leaf clusters, accumulate more ridge-sized substances with cherry blossoms, and lay the foundation for the development of flower bulbs.

3) Flower bulb growth period. From the appearance of the bulbs to the harvest, it takes 15 to 20 days to guess. After the flower bulb appears during this period, the flower buds and flower stems continue to develop and grow, becoming flower balls composed of several shortened fleshy flower stems and flower buds, which meet the commercial harvest standard.

4) Flowering and seeding stage. It takes about 90 days from the time the buds swell and bloom to the seeds are harvested.

Broccoli planting time.

Broccoli is widely cultivated in southern provinces such as Guangdong, Fujian, and Zhejiang. The planting time is divided into two seasons. Sowing can be done in mid-March and harvesting in early June.

Broccoli growth cycle

It takes 80 to 90 days, or three months, for broccoli to be harvested. Broccoli is planted each fall, then cultivated through a whole cold season, harvested the following spring, and then marketed.

Broccoli Growing Costs vs. Profits.

Generally, broccoli can be sold for about 5 yuan a catty, and broccoli of at least 3,000 catties per mu of land can earn about 2,500 yuan. The planting outlook is quite positive.

Broccoli cultivation techniques.

1.Tillage and weeding: In the early stage of broccoli growth, tillage and weeding should be carried out together with top dressing, which can improve the nutrient uptake efficiency of broccoli roots.

2.Timely top dressing: Broccoli trembling grows with more nitrogen fertilizer, and phosphorus and potassium fertilizer should not be too much, otherwise it will germinate early.

In addition to this, some trace elements should be supplemented. 3.Moisture Management:

When broccoli grows, it is necessary to keep the soil moist. When entering the flower bulb formation stage, the soil water content should be controlled at 75%. 4.

Pest control: Broccoli is susceptible to other pests and diseases. Field management should be strengthened to reduce the incidence of disease.
