Avoid direct contact with hands. If you accidentally spill it, first rinse it with plenty of water and then go to the hospital.
Falling leaves in autumn is to reduce the metabolism of plants, which is equivalent to the hibernation of animals. If leaves are added, transpiration will be enhanced, which is not conducive to water conservation and will also accelerate the consumption of organic matter. So at this time, the blade is a burden, it is better to throw it away. The same is true of transplanting rice mainly in late autumn. When plants are dormant, the metabolic rate is the lowest, and the damage caused by transplanting is the smallest. The leaves of evergreen plants that never fall off are often thicker than those of deciduous plants, and the surface is usually covered with a wax protective film.
2.( 1) Go to the supermarket to buy a glove (rubber, PVC, PP, PE will do).
(2) Use plastic cups or pots (sodium hydroxide will corrode glass)
(3) Prepare a pair of bamboo chopsticks or plastic chopsticks to clamp the leaves.
(4) After the blade is corroded, it should be diluted and washed with plenty of water, and then the veins should be cut off (be careful not to damage the veins).
3. If there are leaves, there will be transpiration. It's cold in autumn and winter. If the leaves continue to transpiration, the water transported in the stems may freeze, resulting in plant damage. In addition, the shedding of leaves can reduce the loss of nutrients. In short, deciduous trees fall in autumn as an adaptation to unfavorable environment.
Holly will not shed its leaves. The difference between deciduous trees and evergreen trees is that deciduous trees will lose all their leaves at once in autumn, while evergreen trees will not lose all their leaves at once, but they will also lose their leaves, which will fall off when they are old or damaged by diseases and insect pests.
Hollyleaf has a thick stratum corneum, which can effectively reduce transpiration. In autumn and winter, even if you don't shed leaves, you won't do too much harm to yourself. Similarly, there are pine trees, cypress trees and other trees, whose leaves are more specialized, transpiration is low, and they can not shed leaves in winter.
Tropical and subtropical evergreen broad-leaved trees have no cold environment because of climate reasons. Leaves don't fall out all at once.
You are in the seventh grade, right? Nice to meet you.
