Swiss research uses mushrooms to improve wood properties
The Swiss Federal Materials Test and Research Laboratory said on the 27th that it is experimenting with mushrooms to improve some properties of fir and spruce in order to expand the use of these wood.
Abies and spruce account for 60% of Swiss trees and have the advantages of strong mechanical endurance and easy processing, but they also have weaknesses such as difficulty in fine processing and long-term use. In addition, protective coatings such as fireproof, anticorrosive or anti-ultraviolet coatings are difficult to infiltrate the wood, thus limiting their development and utilization, such as not being used as building exterior materials.
The researchers experimented with wood-eating mushrooms to change this situation, because some parasitic wood-eating mushrooms eat specific ingredients in wood without destroying their strength. They carried out biotechnology research in the laboratory, explored the cultivation time, temperature and specific varieties of mushrooms, and achieved good preliminary results, and the permeability of water-soluble paint of wood modified by wood-eating mushrooms was increased by 8 times.

What is the harm of diamondback moth to cherry blossoms? How to prevent and cure?
What is the harm of diamondback moth to cherry blossoms? How to prevent and cure? The harm of diamondback moth is mainly caused by its larvae biting the leaves of cherry blossoms. The newly hatched larvae ate the residual epidermis of mesophyll in clusters, dispersed the damage when they grew up, and ate up the whole leaves in severe cases. There are many species of diamondback moths that harm cherry blossoms, such as brown-edged green moth, Chinese green moth, camphor moth, small black thorn, and so on. The adults of the diamondback moth are densely scaly, usually yellowish brown to green, with simple red or brown markings. Its larvae, commonly known as itchy spicy seeds, have prickles and poisonous hairs on the body, which can irritate people.

How to prevent mushroom wilt
The dead mushroom is the phenomenon that the small mushroom on the mushroom bed shrinks, yellowes and dies. The mushroom withered in pieces or in batches, which will seriously affect the yield. 1. The reason for the death of mushrooms: 1. The temperature at the end of autumn was too high (more than 23 ℃), and the temperature increased during the period of mushroom emergence in spring (the temperature was 21 ℃ for several consecutive days), resulting in the death of young mushroom seedlings due to lack of nutrition. 2. Due to poor ventilation, insufficient oxygen and high concentration of carbon dioxide in the mushroom room, the heat generated in the process of metabolism can not be released quickly, which will make the young mushroom seedlings due to insufficient oxygen supply or
