Spring flowers and trees should be full of vigor and vitality, but some plants and stumps will begin to wither and even die after sending a few leaves. The reasons are as follows: Watering too much: Excessive watering will cause long-term saturation of the water in the potted soil. The roots of the plant will rot or mold due to lack of oxygen supply, and even cause death. Excessive fertilization: Excessive fertilization or excessive fertilization can easily cause burning of roots, leading to death of plants. In particular, the newly-replaced plants have weak root absorption capacity, and consume mainly nutrients and water in their own bodies. At this time, fertilization is most likely to burn out the roots. Shedging is too early: Spring is hot and cold, and there is a large temperature difference, and the flowers and trees are moved out of the shed prematurely. Flowers and trees can easily cause death because they cannot adapt to the rapidly changing weather conditions. In addition, the soon-to-be-flowered plants in the upper basin just took out new leaves and received sunlight, which would accelerate the evaporation of their leaves, causing the plants to lose water, leading to death. Insufficient water supply: If pots are in a state of drought for a long time, flowers and trees will not be able to absorb enough water. In spring, the temperature rises quickly, the wind is large, and the water evaporates quickly. It is easy to cause unbalanced supply and demand of flowers and trees, and eventually cause death. Inappropriate pH: The biological characteristics of the plants vary, some prefer acidic soils and some have alkaline soils. If plants in acidic soils (such as camellia and rhododendron) are planted in alkaline soils, the plants cannot survive and naturally die, and back there. Diseases and Insect Pests: The main pests that cause the flowers and branches to wither and even die are the scale insects, aphids, beetles, and long-horned cows. Some of them absorb fluids from plant tissue, some of them harm the roots of flowers and some fall into the xylem of flowers and trees. Diseases that cause death of flowers and trees include powdery mildew and blight. To prevent flowers and trees from dying in the summer, the following measures can be taken: The amount of water: For the general flowers and trees, the principle of watering is: do not do not poured, pouring is drenched. In the flowering process, the initial symptoms of excessive watering are: the young leaves turn light yellow, the old leaves do not change much or the color darkens. When this symptom occurs, it is necessary to appropriately reduce the amount of watering and the number of watering, and loosen the soil once. Severe symptoms should be changed again. For plants that have been in a state of drought for a long time, increase the amount of watering. Sometimes the whole potted plants can be placed in a bucket filled with water, and let it be immersed for a period of time to make the potted soil soaked. At the same time, water is sprayed on the flowers and leaves to ensure a balance between supply and demand for water. The symptoms of mild drought are as follows: first, the old leaves yellow and gradually develop into new leaves. Reasonable fertilization: The principle of potted fertilization is thin and heavy fertilization, ie, the amount of fertilization each time is less, but the frequency of fertilization is more. In order to meet the demand of flowers and trees for nutrients, 0.5% urea liquid fertilizer or 0.25% potassium dihydrogen phosphate liquid fertilizer can be formulated for foliar application. Excessive fertilization or excessively high fertilization can cause fertilizer damage. Symptoms of mild injury are as follows: old leaves gradually yellow off, new leaves are thick and shiny. Timely out of the shed: All flowers and trees should not be moved out of the shed prematurely, and should be moved out after the weather is stable. In particular, the new pots and trees should not be moved out of the shed and exposed to sunlight in advance, but should be kept in the shed or a cool, ventilated place for a period of time (usually until mid-April). Gradually move to sunlight. Basin soil is properly formulated: In the process of basin soil preparation, it is necessary to consider its fertility status, but also to consider its pH, to see if it meets the biological characteristics of the species. If the pH does not meet the requirements, new soil should be prepared as soon as required. Effective control of pests and diseases: control of scale insects and aphids with 40% omethoate 1000 times -2000 times liquid or other insecticide spray. Prevention and control of chafers using black light traps to kill adults, artificial killing adults or insecticides. Bacterial damping-off can be treated with 70% thiophanate-methyl WP 1000 times at the beginning of the disease.
Antimalarial:
Antimalarial
medications, also known as antimalarials, are designed to prevent or cure
malaria. Such drugs may be used for some or all of the following:
Treatment of
malaria in individuals with suspected or confirmed infection
Prevention of
infection in individuals visiting a malaria-endemic region who have no immunity
(Malaria prophylaxis)
Routine
intermittent treatment of certain groups in endemic regions (Intermittent
preventive therapy)
Some antimalarial
agents, particularly chloroquine and hydroxychloroquine, are also used in the
treatment of rheumatoid arthritis and lupus-associated arthritis.
Current practice
in treating cases of malaria is based on the concept of combination therapy,
since this offers several advantages, including reduced risk of treatment
failure, reduced risk of developing resistance, enhanced convenience, and
reduced side-effects. Prompt parasitological confirmation by microscopy, or
alternatively by rapid diagnostic tests, is recommended in all patients
suspected of malaria before treatment is started. Treatment solely on the basis
of clinical suspicion should only be considered when a parasitological
diagnosis is not accessible.
Antiparasitic:
Antiparasitics are
a class of medications which are indicated for the treatment of parasitic
diseases, such as those caused by helminths,amoeba, ectoparasites, parasitic
fungi, and protozoa, among others. Antiparasitics target the parasitic agents
of the infections by destroying them or inhibiting their growth;[4] they are
usually effective against a limited number of parasites within a particular
class. Antiparasitics are one of the antimicrobial drugs which include
antibiotics that target bacteria, and antifungals that target fungi. They may
be administered orally, intravenously or topically.
Broad-spectrum
antiparasitics, analogous to broad-spectrum antibiotics for bacteria, are
Antiparasitic Drugs with efficacy in treating a wide range of parasitic infections
caused by parasites from different classes.
