Apple tree grafting attention

Affinity, the closer the affinity between the scion and the rootstock, the stronger the affinity, and vice versa; the temperature, the temperature at the grafting is between 20 °C and 25 °C; the humidity, the saturated humidity in the air is very favorable for grafting; the light is in the dark Under the condition, the callus of the grafted part grows faster and the survival rate is higher. The water content of the scion and the water content of the scion will directly affect the graft survival rate. In operation, the scion is usually soaked in water.

Silicon Nitride Ceramic Plate

Si3N4 ceramic is an important structural material. It is a kind of super-hard material. It is lubricious and wear-resistant. It does not react with other inorganic acids except hydrofluoric acid. It has strong corrosion resistance and resistance at high temperature. It is also resistant to thermal shock. It is heated to above 1,000 °C in air, and is rapidly cooled and heated rapidly without cracking. It is precisely because of the excellent properties of Si3N4 ceramics that it is often used to make bearings. Mechanical components such as gas turbine blades, mechanical seal rings, permanent molds, etc. If the Silicon Nitride Ceramics with high temperature resistance and heat transfer resistance are not used to manufacture the heating surface of engine parts, not only can the diesel engine quality be improved, fuel can be saved, but thermal efficiency can be improved.
