Does planting lotus root without chemical fertilizer affect the growth of lotus root?

The nutrients required by lotus root in the process of growth and development come from the photosynthesis of lotus leaves; On the other hand, it comes from the soil, and the original fertilizer in the soil is limited (including basal fertilizer), which will become less and less as the plant grows and develops, so it must be topdressed in time.

The first time is carried out when the standing leaves begin to appear, and after cultivating and weeding, 750-1000 kg of human manure is applied per mu.

The second top dressing is carried out when there are 5-6 vertical leaves, and about 1000 kg of human manure is applied per mu.

The third topdressing is carried out when the end leaves appear, and this is when the lotus root begins, which is called top dressing. Apply 1500 kg of human manure and urine fertilizer per mu, and 30-50 kg of cake fertilizer.

Precautions for lotus root fertilization:

1. Fertilizing lotus root should be done in sunny and windless weather, and avoid being carried out at noon in the scorching sun.

2. The lotus root is released before each fertilization, so that the fertilizer can be sucked into the water, and then irrigated to the original depth.

3. In the deep-water lotus root field, the fertilizer is easy to be lost, and the liquid fertilizer cannot be directly applied, so the method of solid fertilizer application should be adopted. That is, the manure is reapplied and buried in the mud.

4. When using chemical fertilizer for lotus root top dressing, first fully mix the chemical fertilizer with river mud to make a fertilizer mud ball, and then apply it to the lotus root field.

Lotus root is suitable for deep and fertile mud layer, rich in organic matter of clay loam, lake soil, yellow clay soil cultivation, generally combined with tillage and land preparation, 2500 3000 kg of farm fertilizer per mu, 60 80 kg of general compound fertilizer, 50 100 kg of quicklime.

Lotus root, also known as lotus root, belongs to the rhizome of lotus plants, which can be used for food and medicine.

It is planted in Jiangsu, Zhejiang, Hubei, Shandong, Henan, Hebei, Guangdong and other places in China.

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.

The growth and development of lotus root is divided into three stages, namely the germination stage, the flourishing stage and the root-bearing stage. The budding period of lotus root is sleepy and slippery, from the bud of the plant to the erection of leaves. After the leaves are erected, the lotus root grows new roots, mainly relying on the nutrients stored in the lotus root; In the long term, from the erection of leaves to the beginning of lotus root, the nutrient demand is large, which is the key period of top dressing. During the lotus rooting stage, from the setting of the lotus root to the harvest, the lotus root and lotus seed developed synchronously, the nutrient absorption decreased, and most of the nutrients from the stem and leaf were transferred to the lotus root and lotus seed.

According to the growth habit of lotus root, it is recommended that growers do 3 times of fertilization.

Summary. Plantar fertilizer is applied when the soil is ready. The base fertilizer of shallow water lotus root is mainly organic fertilizer, and there are many types of organic fertilizer, including crop straw, humic acid fertilizer, microbial fertilizer, farmhouse fertilizer, compound fertilizer and so on.

4000 to 5000 kg of farmhouse fertilizer and 100 kg of ternary compound fertilizer can be applied per mu. After applying the fertilizer, turn it 20 cm to 30 cm deeper, mix the soil and fertilizer, and then level the bottom of the whole pool.

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

The base fertilizer of shallow water lotus root is mainly organic fertilizer, and there are many types of organic fertilizer, including crop straw, humic acid fertilizer, microbial fertilizer, farmhouse fertilizer, compound fertilizer and so on. Each mu can be applied to Yifuyuan biological fertilizer starter 4000 kg of rotted farmhouse fertilizer to 5000 kg of trace demolition envy and 100 kg of ternary compound fertilizer.

After applying the fertilizer, turn it 20 cm to 30 cm deeper, mix the soil and fertilizer, and then level the bottom of the whole pool.

Summary. Hello, yes.

When the lotus root is topdressed, the root system of the lotus root is weak and needs sufficient fertilizer. After the plantar fertilizer is applied, it is generally necessary to apply the fertilizer twice during the growth period. For the first time, 750 kg of manure per mu was applied at 3 4 vertical leaves; The second application is applied before the appearance of the leaves at the same dosage as the first.

Fertilization should be done in a sunny and windless weather, early in the morning and in the evening. Before each fertilization, shallow field water should be put to let the fertilizer suck into the soil, and then irrigate to the original degree, and pour water to rinse the lotus leaves after top dressing.

Can you apply manure when planting lotus roots?

Hello, yes. When the lotus root is topdressed, the root system is weak, and sufficient fertilizer is needed. After the plantar fertilizer is applied, it is generally necessary to apply the fertilizer twice during the growth period.

For the first time, when 3 or 4 vertical leaves were applied, 750 kg of manure was applied per mu of manure; The second application is applied before the appearance of the leaves at the same dosage as the first. Fertilization should be done in a sunny and windless weather, early in the morning and in the evening. Before each fertilization, shallow field water should be put to let the fertilizer suck into the cavity of the soil, and then irrigate to the original degree, and pour water to rinse the lotus leaves after top dressing.

The lotus root field should be kept shallow for more than ten days after planting until the budding stage, which is conducive to raising the ground temperature and promoting germination. As the plants grow and develop, the water level gradually deepens. Shallow pond lotus root is generally kept in the water depth of 20 to 25 cm, and deep pond lotus root can be kept at about 30 35 cm.

There is no need to change the water at this time, and the water can flow slowly and cautiously, but not too much, otherwise the fertilizer will be lost. If the weather is dry, you can also spray some water on the leaf surface, which will increase the humidity in the air, promote the growth of lotus roots, and increase the strength of the distribution skills. If there is a heavy rain, if the water surface overflows the lotus leaves, the water must be drained in time, and the original water level must be maintained, and the water in the lotus root pond should be put at a shallow water level 1 month before harvest to promote the vigorous formation of lotus roots.

The water level in the lake is affected by weather conditions, especially on rainy days, the water level is generally shallow in spring, the water level is relatively deep in summer and autumn, and the lake water is prevented from rising sharply in summer and autumn to submerge the standing leaves, and there are no special circumstances, so as to drain in time, if the water level rises in stormy weather, if it is a windy day, the water should be raised to stabilize the wind and waves, protect the lotus leaves, but the water level can not exceed the leaves, and the water level will be discharged immediately after the typhoon, and the water level will be maintained in the original Nadabi.

Planting lotus root has requirements for soil quality, the growth environment of lotus root, and the environmental requirements for lotus root growth.

1. The soil in which the lotus root grows.

Lotus root can grow in loam, sandy loam and clay loam, but humus rich in organic matter is the most suitable. A pH of 6 is desirable for the soil. Excessive acidity and soil compaction are not conducive to the growth of lotus root.

Soil that is too loose is also not good, because the lotus root formed in this soil has short internodes, coarse and hard skin, and poor quality.

2. The temperature at which the lotus root grows.

Temperature plays an extremely important role in the growth of lotus roots. In the spring, budding begins to grow when the temperature rises to around 15, and the temperature is 20-30. The temperature is vigorous and the optimum temperature is 25 30 during the growing season.

When the temperature exceeds 35, the vegetative growth is affected, when the temperature drops below 15, the plant basically stops growing, and when the ground temperature drops below 5, the lotus root is susceptible to frost damage. In the early stage of lotus root formation, a higher temperature is required to facilitate the expansion of the lotus root, and in the later stage, a large temperature difference between day and night is required to facilitate the accumulation of nutrients and the enrichment of the lotus root. The flowering, fruiting, and ripening time of lotus root often varies depending on the temperature.

Generally, the average daily temperature is high, and the time required is short, and vice versa, it is prolonged.

3. Water requirements for lotus root growth.

Lotus root is always inseparable from water during the growth period, but different ecological types have different adaptability to water level, and some adapt to deep water. The adaptability of the same ecological type to water level at different stages of growth and development is also different, and shallow water is generally needed in the early stage to increase ground temperature and promote germination. Deep water is needed in the medium term to facilitate growth; In the later stage, shallow water is needed to facilitate lotus root formation and fruiting. Usually the water can not flood the standing leaves, otherwise even if it recedes within 1 2 days, it will cause a large reduction in yield, if the submersion time is too long, the plant will die.

4. The growth of lotus root requires light.

The growth and development of lotus root requires sufficient light. Sufficient light in the early stage is conducive to the growth of stems and leaves, and sufficient light in the later stage is conducive to flowering and fruiting and the fullness of the lotus root. The requirements for the length of sunshine are not too strict for lotus root, but generally long sunshine is more conducive to vegetative growth, and short sunshine is more conducive to lotus root.

5. Lotus root fertilization method.

Lotus root likes large fertilizer, and its growth requires sufficient base fertilizer in addition to the growth period. The base fertilizer should be based on organic fertilizer, phosphorus and potassium fertilizer, and generally do not use fast-acting nitrogen fertilizer as base fertilizer, otherwise it will cause growth. Lotus root varies depending on the variety.

6. Wind lotus root is afraid of strong winds. When the wind exceeds 15 meters, the lotus stalk and peduncle will be lodging and broken, which will affect the growth and development of the lotus root. In case of heavy rain or water level after the petiole or peduncle is broken, water can be poured into the underground stem from the airway, causing the rot of the underground stem and causing loss of production.

Therefore, in the process of lotus root planting, we must do a good job of preventing strong winds.

The amount of fertilization of the lotus root field base should be determined according to the soil fertility and thinness, generally choose the loose soil, fertile, rich in organic matter, convenient irrigation and drainage of the field, combined with the land preparation per mu to apply 2500 3000 kg of animal manure, 25 kg of diammonium; 10 15 kg of potassium sulfate, 50 100 kg of quicklime, 50 kg of superphosphate, 150 kg of cake fertilizer, rake flat!

Top dressing of lotus root 3 times throughout the growth period. The first application was applied at 1 2 erect leaves (25 days of planting), combined with cultivating and weeding, 3 5 kg of urea per mu or 750 1000 kg of human manure and urine were applied; The second time there are 5 6 vertical leaves (40 days after the agreed planting, when the line is about to be closed), 20 25 kg of compound fertilizer, 5 kg of urea, or about 800 kg of human manure and urine fertilizer per mu; The third top dressing is carried out when the leaves appear, and then the lotus root begins, that is, the top dressing fertilizer, 1000 1500 kg of manure and urine fertilizer per mu, 30 50 kg of cake fertilizer, the third top dressing is mainly based on supplementing potassium fertilizer, about 10 kg of potassium sulfate fertilizer per mu, or spraying potassium dihydrogen phosphate foliar fertilizer, spraying 1 time every 7 days.

Fertilization should choose sunny and windless weather, avoid the noon of the scorching sun, put shallow water level, conducive to fertilizer infiltration into the soil, and then irrigate to the original depth, in the deep water lotus root field, fertilizer is easy to lose, so can not be directly applied liquefied fertilizer, should be applied solid fertilizer, that is, reapply grass green manure, and buried in the mud pond, when topdressing with chemical fertilizer, first the fertilizer and river mud are fully mixed, made into a mud ball, and then applied to the lotus root field.
