The most important aspect of pear tree management in early spring is: "The rational allocation of tree storage nutrients and the reduction of useless consumption are one of the important techniques for promoting the normal growth of trees and producing high quality fruits." During this period, the useless consumption of the tree can be reduced by measures such as buds and buds. The method is as follows: After the spring buds sprout, they should be wiped off when they are 2 to 5 mm long. The time of germination should be as early as possible until the flowering period. If the delay time can reduce the occurrence of long branches, the loss of storage nutrients is more, and it is easy to weaken the tree. After cutting off the big skills in winter, it is often easy to form long skills or useless techniques. In this case, it should be erased in time. The flower buds can be removed from the scales until they are flowered, but it is better to remove them when the buds are exposed. When the bud is scattered, the flower bud can be pressed from the top to the bottom with a finger to break the stalk. At the same time, care should be taken to protect the young leaves that grow in the inflorescence. When sparse buds, generally retain an inflorescence according to the standard of about 20 cm, and control the upper growth with fruit; when the buds sprouting later are removed, when the inflorescences are extended, the accessory inflorescences should be removed in time to preserve the normal flowers. When the pollination conditions are good and some of the flowers have been fertilized and can meet the high yield requirements, the stone sulphur mixture can be sprayed in combination with pest control to kill the late flower stigma and play a role in flower thinning.

Let`s talk about several Cosmetic Raw powders here.Kojic acid, is a kind of organic compound antioxidant and radiation protection agent. It is used in Cosmetics. In human skin, tyrosine is catalyzed by tyrosinase to Synthesize Melanin through complex oxidation and polymerization with oxygen free radicals. Kojic Acid can inhibit the synthesis of tyrosinase, and thus can strongly inhibit the formation of melanin, and safe non-toxic, does not produce white spot sequela, so Kojic Acid has been allocated into lotion, facial mask, lotions, creams, can effective treatment of freckles, age spots, pigmentation, acne and other high-grade whitening cosmetics..Resist wrinklesProducts,Oligomeric Proantho Cyanidins,AntiCaprylhydroxamic Acid in Skin,Sepiwhite Msh Powder Factory,Glycyrrhizic Acid Foods
