How to remedy the wilting leaves of saplings after rain?

It may be that you are not used to the soil, or it may be that you have too much water and cannot breathe air.

The leaves of the crops wilt after the rain, which may be due to poor soil drainage, resulting in stagnant water and rotten roots, affecting growth, it is recommended to drain water in time, and plant in well-drained loam soil.

Analysis Notes Processing:

Leaf wilting after rain is most likely caused by flooding, and the roots are soaked in the soil and produce rotten roots, causing the leaves to wilt.

You can pull out a crop to observe the rhizome, and the root system of the plant after waterlogging generally shows black roots and yellow roots.

Drainage should be carried out in time due to waterlogging. If the drainage is in sunny weather, it is advisable to slow down the drainage speed when the temperature is high.

The shallow water layer is moderately reserved in the field to prevent the emergence of wilt seedlings.

After the water recedes, the seedlings are straightened and the rotten leaves and yellow leaves are removed.

Increase the application of fast-acting fertilizer, and apply fertilizer according to the fertilizer needs of plants.

Generally, nitrogen fertilizer is the main fertilizer, with phosphorus and potassium fertilizer, 3 days after drainage, urea and potassium chloride are applied 5 6 kg per mu, mixed and sprinkled.

It is best to cooperate with potassium dihydrogen phosphate for foliar spraying 1 2 times to improve the photosynthetic efficiency of leaves and make the seedlings recover their growth as soon as possible.

The amount of fertilizer applied to early rice should be appropriately more, in the later stage to promote the growth of panicle type, attention should be paid to the supplemental application of flower fertilizer, 4 6 kg of urea per mu, when the heading is 20%, the gram "920" per mu is used to promote the heading neatly.

In the later stage, combined with the growth situation, pay attention to pest control.

Hello, you can.

1. Clean the ditch and drain it in time to prevent damage. For those who usually do not pay attention to drainage and do not have drainage equipment, especially some orchards on low ground, as well as orchards that often cause poor drainage and are prone to waterlogging after heavy rainfall, it is necessary to remove the water accumulation in the orchard in time to promote the reduction of groundwater level and orchard humidity, enhance the resistance of fruit trees and plants, and reduce the occurrence of diseases. Young orchards should open deep drainage ditches to communicate with each other, and the rain stops drying to promote the steady growth of the root system.

2. Fertilization. After heavy rainfall, the application of well-rotted and thinly decomposed human manure in orchards and nurseries for extra-root topdressing can effectively improve the disaster resistance of fruit trees. Increasing the application of nitrogen fertilizer in orchards with many rainy and sunny days can promote the improvement of photosynthesis of fruit trees, reduce the nitrogen hunger of fruit trees after waterlogging in high panicle stalls, and reduce the yield loss of fruit trees.

Fruit trees that have passed the harvest period should not be left unattended, and they should be protected so as not to affect the next year's harvest.

3. Spray appropriately to prevent diseases in advance. After strong wind and heavy rain washing, fruit tree branches, leaves, roots become fragile, susceptible to pathogen infection, at this time should be applied fertilizer foliar spray, can repair damaged cells, provide nutrients such as trace elements, direct sterilization at the same time can be the effective adult knowledge absorbed by the leaves to the root system, kill the root system of germs. It should be noted that if it rains within 4 hours after application, it needs to be re-sprayed.

Spray 2 3 times in a row, with an interval of 5 to 7 days each time.

People move to life, trees move to death!

There are many factors that go into this, the environment is important, soil, moisture, temperature, humidity, planting density, etc. Various varieties must be grown in its adaptation to the environment. It is recommended to find a garden expert to help transplant and take care of the transplant and learn the basics!

Death is possible.

It is advisable to remove excess branches and cover with shade nets.

It is really not possible to hang salt water on the tree to maintain moisture.

Lack of water, lack of fertilizer, improper light may be early leaves are not good, watering to see wet on it, don't water too much, otherwise it will rot the roots, fertilize once a week on it. It is best not to put it in a particularly sunny place.

1. The function of flowers.

Flowers are the sexual reproductive organs of seed plants that can reproduce offspring for plants. Flowers use their color and smell to attract insects to spread pollen.

However, some plants only have small, lifeless petals, so they use brightly colored leaves or sepals instead of petals to attract insects.

Plants of the genus Opium Poppy grow very quickly, flowering and dying within a year, and are called "annual plants". A single poppy flower can form hundreds of seeds. But not all plants are like this, many more plants can live for a few years, such plants are called "perennials".

The bloom of flowers. The bud body of the flower is a kind of "small suitcase" that is stuffed. It is covered by a tough outer skin that prevents it from being harmed. Inside, the different parts of the flower are tightly wrapped so that they take up very little space. When the bud body grows, the flower is inside.

Soon, the flowers begin to grow so large that the bud bodies can no longer accommodate them, and then they begin to bloom into beautiful flowers.

2. Flowers. It is the reproductive organ of angiosperms (angiosperms, also known as flowering plants), and its biological function is to combine male sperm cells with female egg cells to produce seeds. This process begins with pollination and then fertilization, which leads to the formation of seeds and their dispersal. For higher plants, seeds are their offspring and are the main means of natural distribution of species.

The combination of flowers that grow on the same plant is called an inflorescence. Flowers are also often referred to as "flowers" or "flowers" in life. In the broad sense, fresh flowers can refer to all plants with ornamental value, while in the narrow sense, they can refer to all flowering plants.

In addition to being the reproductive organ of angiosperms, flowers have always been loved and used, mainly for landscaping, interpersonal communication, and as a food**.
