What is the growth process of lotus root? When does the lotus root sprout and grow leaves?

1. Bud germination period.

The budding period is the period from the beginning of budding to the time when the first standing leaves grow out of the water. Lotus root is generally propagated with seed root, and can also be propagated with lotus seeds. When it rains in Qingming Valley, when the temperature rises to about 15, the top buds of the lotus root begin to germinate.

As the temperature rises, the lotus whip is drawn and the money leaves and floating leaves grow. Xiaoman.

Around the clock, when the temperature reaches 18 21, it takes root and grows erect leaves. During the germination period, the nutrients required by the plant mainly depend on the nutrients stored in the lotus root. After the erection of leaves, it mainly absorbs nutrients from the soil.

2. The growth period of stems and leaves.

The stem and leaf growth period is also known as the vigorous growth period. During this period, it takes about 2 months to start with the appearance of the leaves before and after the beginning of the summer and the beginning of autumn.

After the plant extracted 1 2 vertical leaves, the side whip began to occur on the main whip, and the branches gradually increased with the vigorous growth of the stem and leaves. After the summer solstice, when the temperature reaches 25 30, the plant grows most vigorously, and produces leaves about every 5 7 days. Lotus lotus is generally in the summer heat.

It blooms in the summer and blooms best around the beginning of autumn. This period is the main period of vegetative growth of plants, which not only requires the plants to grow as soon as possible to reach the point where the lotus leaves are sealed, so as to lay the foundation for the production of lotus root and accumulate a large amount of nutrients, but also to prevent crazy growth and delay the formation of lotus roots. Therefore, in terms of management, it is necessary to promote the combination of control and reasonable fertilizer and water management.

3. Lotus root and fruiting period.

From the appearance of the leaves to the complete cessation of growth, most of the leaves are yellow, and the lotus root body is hypertrophied and full, which is the lotus root stage. The rooting period varies depending on the variety, cultivation method and environmental conditions. Generally, early-maturing varieties set roots earlier than late-maturing varieties, shallow water sets roots earlier than deep-water roots, and southern varieties set roots earlier than northern varieties.

After the leaves appeared, the tip of the lotus whip elongated from the previous horizontal direction to the oblique downward growth, the internodes thickened, the number of nodes increased, and a new lotus root began to form. Generally speaking, both the main whip and the primary branch can form a new lotus, while the secondary branch can form a new lotus root, and some cannot form a new lotus. The early-maturing varieties begin to form lotus roots around the beginning of summer, and the lotus root body is basically finalized after the beginning of autumn, and the tender lotus roots can be harvested, but to make them fully mature, it needs to be around the autumn equinox, when the aboveground leaves are yellow.

When the cold dew and frost fall, the aboveground part is completely dead, and the lotus root whip rots, and the new lotus root can be left underground for wintering. While the main stem and branches of the underground are successively bearing lotus roots, the aboveground parts also bloom and bear fruit accordingly, and each flower generally takes 30 to 40 days from flowering, pollination, fertilization to lotus seed maturity.

The growth and development of lotus root can generally be divided into five periods: germination stage, stem and leaf growth stage, rhizome expansion stage, flowering and fruiting stage, and overwintering dormancy stage.

1. Budding period (mid-April to mid-May). When the average temperature in spring is 15 21, the top buds, side buds and leaf buds of lotus root begin to germinate, grow lotus whips, and successively produce "lotus leaves", "floating leaves" and "standing leaves".

2. Stem and leaf growth period (late May to mid-July). From the beginning of the vertical leaf growth to the beginning of the lotus root, the temperature rises rapidly, the average temperature in October is 21 28, the stem and leaf grow rapidly, and the number of leaves also increases rapidly with the elongation and branching of rhizome.

3. Rhizome expansion period (late July to early October). At this time, the average temperature in October is 29 19, and the top of the lotus whip grows forward and downward, and grows thick lotus roots.

4. Flowering and fruiting period (early June to mid-September). In the peak growth period of stems and leaves, when there are 3 or 4 vertical leaves, lotus flowers can be extracted at the same time on the back of the vertical leaves on the underground stem nodes of lotus lotus, generally 1 leaf and 1 flower, but the early maturing lotus root has no flowers.

It takes 30 to 40 days from flowering to fruit ripening.

5. Overwintering dormant period (mid-October to early April of the following year). At this time, the average temperature in October was 3 18, the aboveground growth of the plant gradually stopped and died, and the underground part overwintered with lotus whip and swollen nutrient storage organ, lotus root. From the germination of the lotus root to the formation and harvest of new seed lotus, the whole growth period is about 180 days.

The growth process of lotus root is divided into three stages:

1.Root germination period: from the beginning of root root germination to the occurrence of erect leaves, it lasts more than 20 days. At this stage, the nutrients are mainly provided by the lotus root. When the lotus whip grows to a certain length, the nodes of the lotus whip begin to take root and absorb nutrients from the soil.

2.The peak period of growth of assimilated organs: from the beginning of the extraction of the erection of leaves to the appearance of the posterior leaves, it lasts for about 80 days, which is the main period of vegetative growth of plants. At this stage, it is necessary to prevent overgrowth to avoid delaying the setting of lotus roots.

3.The formation period of new lotus root: from the full flowering period to the harvest of tender lotus root, it lasts more than 20 days. The early-maturing varieties set early under the conditions of shallow water and dense planting. Under the influence of water depth and typhoon, the late-maturing varieties have delayed the formation of lotus roots.

The growth of lotus root is also affected by factors such as temperature, water level, pests and diseases.

According to the law of growth and development of lotus root, it is generally divided into five periods: seedling stage, seedling stage, flower and fruit stage, root bearing stage, and dormancy stage

1. Seedling stage: from the germination of the rhizome of the lotus root to the display of the first vertical leaf. When the average temperature rises to 15, the lotus root begins to sprout, and the leaves that grow during this period are all floating leaves.

In the middle and lower reaches of the Yangtze River, generally in early April, the lotus begins to sprout and grow floating leaves, and in mid-May, it pulls out erect leaves. In Yunnan in southern and southwestern China, germination and growth begin in early March, while in Henan and Shandong in northern China, germination and growth begin in late April or early May. The Tohoku region will not begin to sprout until early June.

The phenological period of lotus is also closely related to the variety. In general, the germination period of lotus is the best period for lotus root planting. 2. Seedling stage:

From the appearance of the first erect leaf to the appearance of buds. The middle and lower reaches of the Yangtze River generally enter the seedling stage from mid-May. The typical characteristics of this period are that the growth rate of the plant is accelerated, the number of leaves is increasing, the total leaf area is increasing, the efficiency of photosynthesis is strengthened, and the formation and accumulation of nutrients are also accelerating, forming a huge nutrient system in a short period of time.

3. Flowering and fruiting stage: from the budding of the plant to the appearance of the terminal leaves. The flowers of the lotus root bloom one after another, and the flowering period generally lasts for about 2 months.

The amount of flowering varies depending on the variety, and after the lotus grows 3 or 4 vertical leaves, it is basically one leaf and one flower. Whereas, lotus has few or no flowers. In the middle and lower reaches of the Yangtze River, buds generally begin to bloom in June, and the peak flowering period is July and August.

4. Lotus rooting stage: from the appearance of the leaves in the back to the yellowing and wilting of the aboveground parts of the plant. When the lotus grows to a certain period, the rhizome begins to swell to form lotus roots, and the early-maturing varieties generally enter this period in early July, and the mid-late maturing varieties enter this period in late July or early August.

5. Dormant period: from the aboveground part of the plant turns yellow and withers, and the new lotus root is fully formed, until the leaf buds and apical buds of the next spring.

until germination begins. The Yangtze River basin generally has a dormant period from late October to March of the following year.

Lotus roots grow in ponds, and they begin to sprout in April every year, growing round leaves, and in the summer, beautiful lotus flowers bloom.

Lotus root germination is generally the end of March, the leaves are the beginning of April, in Jiangsu, it is this time, if you want to delay germination, you can throw the lotus root into the water tank to preserve, you can delay until May and then plant.

Lotus roots generally begin to sprout and grow leaves at this time.

In April, you can see the small lotus leaves emerging from the water.

Problem description: Spring. Shape. Summer. Shape.

Autumn. Shape. Analysis:

Bowl lotus is cultivated by using the lotus root body as a seed root, and in a growth cycle, it has to go through the process of germinating oranges, spreading leaves, flowering, fruiting, growing lotus roots, and dormancy. From the germination of lotus root to the beginning of summer and Xiaoman, it is the germination and unearthing stage. After the vernal equinox, when the temperature rises to more than 10 degrees Celsius, the lotus root buds on the seed root begin to germinate, after Qingming, when the temperature reaches more than 15 degrees Celsius, it begins to grow floating, and the lotus root whip is drawn; When the temperature reaches more than 20 degrees Celsius, the main whip pulls out erect leaves, and has a strong root residual sensitivity system, and the fertilizer absorption ability is enhanced.

It is the vigorous growth stage from the time the leaves grow to the time they appear. In late June, the rainy season begins, with more rain, high humidity and high temperature, which is most suitable for the growth of lotus root, and it enters the vigorous growth period at this time. After that, about every 5-7 days, an erect leaf grows, and one is taller than one; The main whip and side whip also grow quickly, and new side whips are born and bloom.

At this stage, it is necessary to strictly prevent the invasion of strong winds and avoid breaking leaves and hurting roots.

Cultivation containers go through the processes of germination, leaf development, flowering, fruiting, lotus root growth and dormancy in a growth cycle.

Introduction to lotus root growth.

Lotus root is native to India, mainly grows in swampy areas, and is distributed in Jiangsu, Fujian, Jiangxi, Zhejiang, Hunan and other places, among which the planting area of lotus root produced in Jiangsu and other places ranks first.

Lotus root growth cycle.

Lotus root is suitable for planting in low-lying areas, ponds, and lakes, and needs to be grown in hot and rainy seasons. Lotus roots usually grow from May to September.

Lotus root growth rate.

Lotus root generally reproduces vegetatively by enlarged rhizomes, and the whole growth period is about 180-200 days. When the temperature of the lotus root is above 20, the lotus root whip is rapidly elongated, and the plant begins to grow vigorously. When the main lotus root whip is about 7 meters long, a new lotus root begins to form.

When the leaves are plucked, the nutrients are concentrated in the new lotus roots.

Lotus root growth cycle management.

Temperature management: Lotus root germinates in an environment of 15 degrees, and it is best to grow in an environment of 25-30 degrees. The temperature dropped to 15 degrees Celsius, and the growth basically stopped.

Fertilization management: Lotus root likes to fertilize, but excessive fertilization will burn seedlings. Therefore, it is necessary to spray a new high-lipid film to improve the utilization rate of the active ingredients of the fertilizer, not afraid of evaporation in the sun, and adjust the water absorption.
