What about the petals of Xie Zao Lan?

In the process of growth and development, potted flowers wither due to environmental factors and flowers themselves, which inhibits the growth of flowers and even makes them die. Measures must be taken to maintain and update them in time.

[color=Red] 1。 Drought and withering: [/color] Flowers and trees failed to be watered in time after a long drought, and withered from the top down, and the branch cortex withered until the whole plant died. In this case, it is necessary to spray water on the dry leaves of flowers and trees and the surrounding environment to maintain a high environmental humidity, and it is forbidden to use a large amount of low-temperature water to irrigate the soil in a high-temperature environment.

[color=Red] Second, water bloom: [/color] If the water content in the soil is too high, the roots of plants will suffocate or suffocate and die. Without water supply from the roots, branches and leaves will wither or even die. For damaged flowers and trees, direct exposure to strong light and strong wind should be avoided, and some tender branches and leaves should be cut off to reduce water evaporation. Plants and trees planted in the ground should be loosened in time. Potted flowers and trees, to remove one-third of the wet pot soil, replant dry soil. Combined with foliar spraying, dilute liquid fertilizer is sprayed every three days. After this maintenance for 65,438+00 days, the damaged flowers and trees can be restored.

[color=Red] Third, fertilizer wilting: [/color] The fertilizer concentration in the soil of flowers and trees is too high, which makes the water in flowers and trees penetrate into the soil (that is, reverse osmosis), commonly known as root burning, which leads to flowers and trees wilting and even death. Damaged flowers and trees planted in the field can be watered in large quantities to dilute the fertilizer concentration in the soil and discharged in time. Pot flowers and trees, remove the topsoil from the pot, water it, let the excess fertilizer flow out from the bottom of the pot with the water, and then cover the surface of the pot with a layer of plain soil. At the same time, measures such as shading and spraying water on the leaves of damaged flowers and trees are taken to maintain the life of flowers and trees, and they can return to normal in 10 to 20 days.

Four. Insect Wilting: [/color] When cattle and Chrysopa grandis are seriously damaged that day, the transportation organization of the trunk or main branch of flowers and trees is destroyed, resulting in local or whole plant wilting or death, and the wilting caused by pests is difficult to recover. Precious flowers and trees can be cut down for cutting or grafting.

[color=Red] V. Wind decay: [/color] When the new shoots of flowers and trees grow in large numbers, flowers and trees tend to wither under strong light and strong wind (especially dry wind). At this time, shading, sheltering from the wind and spraying water on the leaves can prevent the new shoots from losing water and wilting.

Six. Heat Withering: [/color] Flowers that like cool environment in summer will wither, roll, even wither and fall off if placed in strong light and high temperature. It should be placed in a damp, ventilated and cool place immediately.

7。 Cold withering: [/color] The temperature in the north fluctuates greatly, and suddenly drops below 10℃ at night. Some southern flowers, such as hibiscus, jasmine and azalea, will wither and lose their luster in the morning, and gradually recover after the temperature rises at noon. Short-term cold withering has little effect on flowers, but attention should be paid to keeping warm.
