Is there a nutrient solution for lotus root farming? What technology is needed

Lotus Root Cultivation Techniques:

Lotus root is suitable for growing in the hot and rainy season. It is mostly planted in the south of the Yangtze River in early March and early April, and in the Beijing area, it is mostly planted in early May.

Lotus root fields choose slightly acidic or nearly neutral clay soils with deep soil and rich organic matter. Lotus root species should choose the female lotus root or fully mature seed root with the characteristics of the variety, full lotus root, complete neck buds, hypertrophied lotus root, small lotus nodes, thick and strong posterior fat and bright color.

The sowing method should be digging, selecting, and planting, and it can also be planted after germination. Lotus root fields generally maintain a shallow water of 5-6cm in the early stage to promote germination and leaf extraction, and the water depth is 15-16cm in the middle stage; In the later stage, shallow water is put to facilitate the formation of lotus roots. During the growth process, the oxygen in the air and the iron in the soil are combined to form reddish-brown rust spots of ferric oxide, which attach to the skin of the lotus root.

When the lotus leaf withers, the respiration of the lotus root slows down, and the rust spots gradually decrease due to the reduction effect. Therefore, the leaves are picked before harvesting, and the rust spots are easy to wash away. The leaf umbilicus, petiole and underground stem are connected by aeration tissue, so the petiole cannot be broken to avoid water ingress and cause plant rot.

It takes more than 20 days to plant lotus root budding and erection of leaves. At this stage, the nutrients mainly depend on the lotus root. The roots of the lotus root take root at each node and absorb nutrients from the soil to maintain their own growth needs until they reach maturity.

As one of the standing vegetables on people's tables, lotus root has a very high nutritional value. Not only rich in vitamins and minerals, people insist on eating lotus root for a long time, which is conducive to heart development, can promote metabolism, and prevent roughness. It can be seen that lotus root is very helpful to the human body.

Lotus root is cultivated in Jiangsu, Anhui, Hubei, Shandong, Henan, Hebei and other places in China. There is also Nanjing Shi Chen Zhisui wrote the poem "Yonghe": "Being in the sludge is not stained with mud, and no one knows about the white stem buried in the ground." The red and green are clear and vibrant, and the pool is full of fragrance without waiting for the wind to come. ”

Due to the relatively high economic value of lotus root, many people now choose to grow lotus root to increase their economic income. My friend's family also started planting lotus roots, and I also asked a few tips for planting lotus roots during dinner.

First: Choose the right land.

Lotus root prefers acidic or neutral soil, and the soil quality should be rich in organic matter and clayey, alkaline soil lotus root field, lotus root can not grow. In addition, nitrogen, phosphorus and potassium are indispensable for the growth of lotus root.

Second: to choose the size of the lotus root pond.

When the lotus root grows, there are also requirements for the size and depth of the lotus root pond; The lotus root pond is too large, which is inconvenient for planting, management and pest protection; The lotus root pond is too small, which is not conducive to the derivation and growth of lotus root; The lotus root pond is too deep, and it is not easy to dig after the lotus root is ripe; The lotus root pond is too shallow, which is not conducive to continuous water insulation in winter.

Third: Be sure to carry out reasonable fertilization.

In the process of lotus root growth, fertilizer should be added reasonably, and fertilizer should be selected in the morning or evening before fertilization, and at the same time the water in the field should be discharged, and then fertilized. Note that liquid fertilizers should never be used when fertilizing, as this will cause serious damage to the roots. It is necessary to use solid fertilizer and bury it in the soil to ensure that the yield of lotus root is increased.

Let's talk about several effects that lotus root can bring to the human body.

First: clear the fire and cool the blood.

The growth of lotus root is inseparable from water, growing in water since childhood, it is a cold food, eating lotus root, it can be the best heat venereal disease, has the effect of clearing heat, clearing fire, and cooling blood; The effect is especially obvious for patients with thirst, hemorrhage, hemoptysis, and blood loss.

Second: strengthen the spleen and appetize.

Lotus root contains more mucus protein and dietary fiber, these two substances can well combine bile salts in the human body and cholesterol and triglycerides in food, and excrete them from the body to reduce the body's absorption of lipids, making people not easy to gain weight. In addition, lotus root also contains tannins, which can strengthen the spleen and stop diarrhea, promote digestion, and enhance appetite.

Third: Boost immunity.

The nutritional value of lotus root is very high, it is rich in iron, calcium, plant protein, vitamins, starch and other essential nutrients for the human body, which can replenish qi and blood and improve human immunity.

It takes more than 20 days from budding to erection of leaves. At this stage, the nutrients mainly depend on the lotus root. After the leaves are extracted, each node of the lotus whip takes root and absorbs nutrients from the soil.

Therefore, under the premise of saving costs as much as possible, the lotus root should be hypertrophied, the basal fertilizer should be sufficient, the water level should be shallow, and the water temperature should be increased, which is conducive to germination.

The lotus root obtains nutrients through a spiral-shaped duct. Every plant in nature needs nutrients to continue to thrive, and there will be tissues in the body that transport water and nutrients, which play a very large role in the plant, also known as ducts and tracheids, these tissues extend in all directions in the plant, and in the leaves, stems, flowers, fruits and other organs as the blood vessels in the animal body. The inner wall of the duct of each plant will be thickened, some form a trapezoid, some form a net, then the inner wall of the duct of the lotus root will also thicken, but it forms a spiral shape, which is called a spiral duct.

The nutrients of the lotus are produced through the photosynthesis of the leaves, which are transported from the leaves to all parts of the body, and the roots absorb water and nutrients from the soil. The lotus root is the stem of the lotus, called the underground stem Laiyan headline.

Summary. Hello, planting lotus root needs to know, lotus root needs to be applied organic fertilizer to high yield. The basal fertilizer is generally applied to the field before planting, and the amount of fertilizer applied to the lotus root field base should be determined according to the soil fertility.

Planting lotus root, generally to choose loose soil, fertile, high organic matter content, convenient drainage and irrigation of the field, combined with land preparation, it is recommended that growers per mu of lotus root field can be applied to the rotten organic manure 2000-3000 kg, potassium sulfate about 10-15 kg, diammonium 20-25 kg, quicklime 50-100 kg, superphosphate 50 kg, cake fertilizer 150 kg, rake flat.

It is best to adjust the number of grams per mu with Bihu during the leaf standing period of lotus root.

The lotus root leaf stage is best adjusted with 45 grams per mu of Bihu.

So much, rice and wheat are just 7-15 grams.

Lotus root is needed a little more pro.

Okay thank you.

Summary. Hello, how to prevent stiff lotus?

1. Select healthy seed lotus root without rigid symptoms as seeds, select seed lotus, establish improved seed lotus root breeding fields, eliminate the seed roots of diseased fields, and do not select non-stiff lotus roots from lotus root fields with stiff lotus root occurrence as seed lotus;

2. Shorten the continuous cropping period of lotus root field, generally not more than 5 years, and implement lotus root multiple cropping, lotus root, lotus root, lotus root rice rotation, and water and drought rotation is better;

3. The lotus root field is all exhausted before winter, drained and cultivated, frozen in winter, dried in spring, and then soaked in the field to plant lotus root;

4. Increase the application of well-rotted organic fertilizer, and apply organic fertilizer and chemical fertilizer together to make the lotus root plant grow more vigorously. In the growing season, growth regulators such as brassinolide and Bihu can be added to improve the disease resistance of lotus root plants and have a good prevention effect in combination with the prevention and control of other lotus root diseases and insect pests.

5. Once the stiff lotus root is found in the lotus field, it should be completely removed in time. Try to remove the dead stems and residual leaves of the old lotus root field.

1. Water management: Lotus root is an aquatic plant, and it is inseparable from water throughout the growth period. Summer is the peak growth period of lotus root flowers (lotus), and the demand for water is also the largest, so it is necessary to pay attention to the fact that there can be no water in the pool throughout the summer, and the new high-fat film spraying foliar surface makes the branches and leaves green and lush, and the accumulation of photosynthesis products and directional transport ability are enhanced.

2. Fertilizer management: lotus root likes fertilizer, and the demand for fertilizer is more, but too much fertilizer will also burn seedlings, so it is necessary to apply thin fertilizer frequently, spray new high-fat film to greatly improve the utilization rate of effective ingredients of fertilizer, not afraid of sun exposure and evaporation, can adjust the absorption of water.

3. Pest control: aphids, Spodoptera litura, stinging moths, etc. Harm standing leaves and flower buds.

Targeted drug spraying on the surface of plants with a new high-lipid film can improve the efficacy, effectively prevent viral infection of leaves, and make the branches and leaves green and lush. The water maggot sucks the juice of the roots, stems and leaves of the lotus root, and can be killed by lime.

4. Growth period: the quality of lotus root is very high, spraying the fruit can promote the underground fruit nutrient transport duct to become thicker, improve the vitality of the fruit expansion, make the lotus root hypertrophied, the flesh is crisp and tender, the water is more and sweet, the quality is high and high-yield, and the taste is fragrant.

When planting the lotus root, you should give it some fertilizer, and then wait for it to grow seedlings and then fertilize it, and then wait for it to bloom for the third time and then fertilize it again, so that the planted lotus root can grow very well.

I think it's better to apply some nitrogen fertilizer, which will be more helpful to the lotus root, and it will make the lotus root grow faster and taste better, and you need to apply some at regular intervals. In this way, it is more appropriate, and the amount of fertilizer is as small as possible each time it is applied to keep it even.

When planting lotus root, it is better to apply basal fertilizer, and it should be carried out many times, each time with a small amount, the effect will be particularly good.
