The reason why spring flowers and plants are easy to die Insufficient water supply: If the potted soil is in a state of drought for a long time, the flowers and trees will not absorb enough water. However, in spring, the temperature rises quickly, the wind is large, and the water evaporates quickly, which easily leads to unbalanced supply and demand of flowers and trees, which eventually leads to its death. Too much watering: Excessive watering will cause long-term saturation of the water in the potted soil. The root system of the plant will be rotted or moldy 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. Pests and diseases: The main pests that cause the flowers and branches to wither and even die are the scale insects, aphids, scarabs, and long-horned cows. Some of them absorb the liquids in the plant tissues, some harm the roots of the flowers, and some of them fall into the xylem of flowers and trees. Diseases that cause death of flowers and trees include powdery mildew and blight. Shelter is too early: In the spring, the temperature difference between hot and cold suddenly occurs, and the flowers and trees are moved out of the shed prematurely, and flowers and trees are prone to 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 to get exposure to sunlight, which will accelerate the evaporation of leaf surface water and cause plants to lose water and die. Prevention of dead plants Appropriate amount of watering: The principle of watering for general flowers and trees is: do not do not poured, pouring is drenched. Reasonable fertilization: The principle of potted fertilization is that the thin-fertilizer should be applied in a dilute manner, that is, the amount of fertilization should be less but the frequency of fertilization should be 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. Do not over-fertilize or apply too much fertilizer. 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, but not too early to move out of the shed on the sun exposure, but should be placed in the shed or a cool ventilated place for a period of maintenance (usually after the mid-April out of the shed) until its stable growth Can gradually move to sunlight. Basin soil is properly formulated: In the process of basin soil preparation, it is necessary to consider its pH value and consider whether 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: prevention of scale insects and aphids sprayed with 40% omethoate 1000 times or other insecticides; prevention and control of chafers using black light traps to kill adults, artificial killing of adults or insecticides; control of blight in the incidence In the initial stage, 70% thiophanate-methyl wettable powder 1000 times was used to irrigate the roots.
