What is the relationship between the water absorption of plants and fertilizers?

This is related to the osmotic pressure of the cell and the solution around the cell, if the plant is fertilized too much, the osmotic pressure of the soil is greater than the osmotic pressure of the plant cell, and the plant loses water, which is what we often call too much fertilization and burning. If the soil has enough moisture and there is not enough fertilizer, the plant cells will absorb water like crazy, and the roots will rot easily. In general, fertilization is accompanied by an appropriate amount of watering, or the fertilizer is dissolved in water, which is conducive to the absorption of plants.

Your flowers are not necessarily just lacking nitrogen fertilizer, because the lack of nitrogen, boron, magnesium, zinc, iron, etc. can stunt growth, stunted growth, you better change the soil or apply all-element fertilizer, if you refer to the following to determine that a certain element is missing, you can apply it alone to recover.

When nitrogen fertilizer is lacking, urea, ammonium sulfate, and diammonium phosphate can be applied;

Ferrous sulphate is applied when iron fertilizer is lacking;

Borax is applied when boron fertilizer is scarce;

Magnesium sulfate is applied when magnesium fertilizer is lacking;

Zinc sulfate is applied when zinc fertilizer is lacking.

1. Nitrogen deficiency: the growth is stunted, the leaves are small and the color is light, the leaves are sparse and easy to fall, which affects photosynthesis, so the growth is poor, the plants are smaller, the branches are less, and the fruits are small and few.

2. Phosphorus deficiency: the growth is inhibited, the plant is dwarfed, the leaves become dark green, gray and dull, with purple spots, and finally die and fall off.

3. Potassium deficiency: brown spots appear on the leaves, abnormal wrinkles occur, leaf margins are curled, and finally scorched, and the symptoms are like fire.

4. Calcium deficiency: The growth of the root system is inhibited, the root system is many and short, the cell wall is sticky, and the root apical cells are damaged, resulting in rot.

5. Magnesium deficiency: Causes green deficiency, yellowing and white flower disease. Magnesium-deficient flowers often begin to fade green from the lower leaves of the plant, appear yellowing, and gradually spread to the upper leaves, the veins remain green at first, the veins of the later leaves turn yellow, and soon the lower leaves turn brown until they die.

6. Iron deficiency: When iron deficiency, the upper young leaves of the branches are damaged, the lower old leaves are still green, and the mesophyll tissue of flowers is pale green when the iron deficiency is slight, and the leaf veins remain green.

7. Manganese deficiency: When flowers are deficient in manganese, the leaves first turn pale with some gray, and then brown spots are found at the tip of the leaves, which gradually spread to other parts of the leaves, and finally the leaves wither rapidly, the plant grows weaker, and the flowers cannot be formed.

8. Zinc deficiency: Auxin in flowers is destroyed, plant growth is inhibited and diseases are produced. Good zinc nutrition can enhance the resistance of plants to fungal diseases.

9. Sulfur deficiency: It causes green deficiency, and the veins of flowers and leaves are yellow, but the mesophyll tissue still remains green, which can be distinguished from the symptoms of magnesium deficiency and iron deficiency. Sulfur deficiency begins with red blight at the base of the leaves, and usually the top leaves of flowering plants are damaged early, the leaves are thick, the branches are thin and lignified.

10. The growth and development of flowers deficient in trace elements have a greater demand for nitrogen, phosphorus, potassium, calcium, magnesium and sulfur, and less demand for iron, manganese, zinc, copper, boron, selenium, molybdenum, etc. However, the lack of trace elements will also be detrimental to the growth and development of flowers. Therefore, it is necessary to properly apply micro-fertilizer to ensure that the flowers are always bright.

In the process of growth, plants need to absorb water and nutrients to maintain life activities, in which the absorption of water and nutrients is two different processes, but the two are closely related, because there is mutual influence and synergy between them, which are elaborated from the two aspects of water absorption and fertilizer absorption

1. Plants absorb water.

Plant water uptake refers to the process of plant roots absorbing water from the soil, plant water uptake is an indispensable and important factor for plant growth and development, water can maintain the osmotic balance in cells, promote the metabolism and transport of substances, and play an important role in the transmission of nutrients and photosynthetic products in plants. The extent to which a plant absorbs water depends on a variety of factors, including ambient temperature, soil moisture, root and stem length, soil quality, and nutrients. If the soil is too dry, the plant roots will not be able to absorb enough water, which will cause the plant to wilt, and if the soil is too wet, the roots will have difficulty breathing, which will also affect the growth of the plant.

Therefore, maintaining a moderate amount of soil moisture and regulating the appropriate amount of irrigation water is essential for the water absorption process of plants.

2. Plant fertilizer absorption.

Plant fertilizer uptake refers to the absorption of nutrients in the soil by plants through their roots to meet the needs of growth and development. The nutrients absorbed by plants are nitrogen, phosphorus, potassium, etc., which are essential for the growth and development of plants. Nitrogen is an important element essential for plant growth, which can promote the growth and development of plant roots and improve the photosynthetic efficiency of plants. Phosphorus can promote the flowering and fruiting of plants, and increase the photosynthetic peak of plants. Potassium is able to maintain the water balance and osmotic balance of plant cells.

The ability and rate of nutrient uptake depends on many factors, such as the health of the plant's root system, soil structure, and the amount and morphology of nutrients in the soil. If there is a lack of a certain nutrient element in the soil, the plant will have poor growth or a certain ear hand disease, so in the planting management, it is necessary to monitor the content of nutrient elements in the soil from time to time, apply fertilizer reasonably, increase soil fertility, and provide sufficient nutrient support for the nutrient absorption of plants.

In general, water uptake and fertilizer uptake by plants are two different processes, but they are interrelated and synergistic. Insufficient water absorption by plants will reduce the ability of plants to absorb nutrients; Lack of proper nutrients can lead to unworthy growth or death. Therefore, it is very important for the healthy growth of plants to carry out irrigation and fertilization management scientifically and rationally to ensure the balance of water absorption and fertilizer absorption of plants.

What are the characteristics of water-soluble fertilizer? How to apply water-soluble fertilizer!

Water-soluble fertilizer, referred to as water-soluble fertilizer.

It is defined as liquid or solid fertilizer that is dissolved in water and used for irrigation, foliar fertilization, soilless cultivation, soaking seeds and dipping roots, etc.

So what are the characteristics of water-soluble fertilizers? How to apply water-soluble fertilizer? Today, I will share with you the characteristics and application methods of water-soluble fertilizer, let's take a look!

1. Product features:

1) High content, full nutrition, instant water solubility, fast fertilizer effect;

2) Contains nitrogen, phosphorus, potassium and a variety of trace elements;

3) No impurities, no pollution, safe and efficient for crops;

4) Save water, fertilizer, labor, disease resistance, and increase yield.

2. The application method is quietly widened:

It is suitable for field and greenhouse vegetables, melons and fruits and other crops.

1) Flushing: 4-6 kg per mu, 500-1500 times with water, once every 10-15 days.

2) Drip irrigation: 3-5 kg per mu, 1000-2000 times with water, applied once every 7-10 days.

3) Sprinkler irrigation, sprinkler application, and root irrigation can be used.

3. Precautions:

1) The dosage, water concentration and application times per mu should be appropriately increased or decreased according to the season and crop growth.

2) This product is stored in a cool and dry place, and if there is agglomeration, it will not affect the fertilizer effect.

There are still obvious differences between functional fertilizers and water-soluble fertilizers, and molar water-soluble fertilizers are briefly summarized as follows:

Water-soluble fertilizer generally refers to a fertilizer that can integrate water and fertilizer, and the composition is a large number of elements and medium and trace elements, which can improve the yield of crops and is convenient for fertilization.

Functional fertilizer, generally refers to the function different from nitrogen, phosphorus and potassium, such as soil conditioner, microbial agent, anti-heavy cropping agent, humic acid-containing fertilizer, etc., is to play some adjustment ability, the main performance in regulation, increase yield is not its advantage.

Water-soluble fertilizer generally refers to the fertilizer that can integrate water and fertilizer, which can not only save water resources, but also save fertilizer and precise fertilizer!! Functional fertilizers generally refer to those with different functions from nitrogen, phosphorus and potassium, such as soil conditioners, microbial agents, anti-heavy cropping agents, and fertilizers containing humic acid.

As the name suggests, water-soluble fertilizer is a multi-compound fertilizer that can be dissolved in water, which can be quickly dissolved in water, easier to be absorbed by crops, and its absorption utilization rate is relatively high.

Generally speaking, water-soluble fertilizers can contain all the nutrients needed for crop growth, such as N, P, K, CA, MG and trace elements. In this way, people can design the formula according to the characteristics of the nutrient needs required for crop growth, and the scientific formula will not cause the waste of fertilizer, so that its fertilizer utilization rate is almost 2-3 times that of conventional compound chemical fertilizer. Secondly, water-soluble fertilizer is a fast-acting fertilizer, which allows growers to see the effect and performance of fertilizer quickly, and can adjust the fertilizer formula at any time according to the different growth of crops.

Of course, the application method of water-soluble fertilizer is very simple, it can be fertilized with irrigation water, which not only saves water, but also saves fertilizer, and also saves the power of labor and filial piety, which is the benefit of using water-soluble fertilizer in today's increasingly high labor cost is obvious. Since the application method of water-soluble fertilizer is irrigated with water, the fertilizer is applied very evenly, which also lays a solid foundation for improving yield and quality. Water-soluble fertilizers generally have fewer impurities, low conductivity, and the concentration is very easy to adjust, so it is safe even for young seedlings, and there is no need to worry about adverse consequences such as causing or burning seedlings.

Water-soluble fertilizers are not only diverse in formulations but also very flexible in their use, generally there are three types:

Soil watering. Foliar fertilization.

Drip irrigation and soilless cultivation.

Because water-soluble fertilizer has the characteristics of simple use and convenient use, it has been widely used in the world, in foreign countries, it is widely used in greenhouse vegetables and flowers, various fruit trees and field crops irrigation and fertilization, garden and jungle landscape greening plant maintenance, golf course, and even the maintenance of home greening plants.
