Are the lime used for tree cleaning in winter lime or slaked lime? Why?
Lime has bactericidal, insecticidal effect, can kill the parasites in the trunk and some overwintering fungi, bacteria and pests. In winter, the trees will drill into the ground some pests in winter, autumn when the brush on the lime after they get down, winter will freeze to death. Next spring to brush again. Underground after hibernating try to climb the tree is not easy to damage. Because lime will make worms die of dehydration, so they will stay away from flying insects. But this approach is useless.
Most insects do not fly in the nymphal stage in the metamorphosis to grow wings, and insects in the wings (developed) is the main task of post spawning mating, real harm plants when the larval stage (the stage of feeding on leaves in autumn and winter season), the outbreak is not the main pests, measures up the preventive effect of spring and summer there are a lot of insects can be directly sprayed to solve the problem, not to say "tree pest can not fly, have to climb from the ground.
In winter, the night temperature is very low; during the day, sunlight, temperature, and the trunk is dark brown, easy to absorb heat, the trunk temperature rise very quickly. So hot and cold, so that the trunk easily Donglie. Especially the tree trunk, thick, deep color, and toughness and organization relatively poor, more easily cracked. With lime water, the lime is white, can make 40% - 70% of the sunlight is reflected, so the trunk in the daytime and nighttime temperatures are almost the same.Third, because there is a tree in autumn predators, insects also make human troubles raging! It will be a building to get cross, there are wood and space, they were let go, they are called termites, trees with lime, they MEIZHE, usually with 1.5 to 2 meters in height
