Fruit tree pruning is an important step in apple planting, but fruit trees are prone to decay after pruning, so that fruit trees are easily rotted after pruning?
Fruit trees are easy to rot after pruning: Linyi Fertilizer Network Co., Ltd.
Fruit tree sawing wounds are the main channel that currently causes fruit tree rot. Protecting the mouth and cutting is the most effective way to promote wound healing, restore tree potential early, and prevent rot. Linyi Fertilizer Network Copyright
According to the investigation, after the winter shearing and spring shearing, the callus and the anti-corrosion film can be applied to the cutting mouth with a diameter of 0.5-6cm to keep the wound flat and not cracked. The wound does not crack within half a year after application, and the wound heals quickly. The healing tissue was produced 100 days after the oral administration, and the healing tissue around the wound was 0.2-0.5 cm in 150 days; the healing tissue was produced 60 days after the spring shearing, and the wound healing tissue was 0.3-0.6 cm in 100 days. Increased callus by 25% compared to control. Moreover, the number of germination of the wound can be increased, and the growth is prosperous. The average number of germination of the treated wound is 1.8 times higher than that of the control at 2.7. Linyi Fertilizer Network Copyright

Ordinary mullite porcelain is made of aluminosilicate natural minerals as a main raw material, and is formed by a reaction sintering method in which a eucalyptus is synthesized in a sintering process or a mullite is first synthesized and then sintered. Due to the low purity of raw materials and high impurity content, in addition to Al2O3 and SiO2, the components also contain impurities such as TiO2, Fe2O3, CaO, MgO, Na2O, K2O, etc., so that there are a considerable amount of glass phase in the product, resulting in mechanical and thermal properties. Poor, the excellent performance of mullite ceramics at high temperatures cannot be fully utilized. Therefore, ordinary mullite ceramics in the industry can only be used as a general refractory material in the case where the temperature and high temperature strength are not high.
