How to properly use pollution-free plant growth regulators in the production of pollution-free tea? Promoting the use of bud growth regulators Plant regulators widely used in the production of pollution-free tea in China are brassinolide, BR-120 and Tianfengsu. After applying the plant growth regulator, the tea tree can promote various activities of the growth of the leaves. Its use method is: in the tea tree growing season, use 0.01% BR-120 EC (if using rapecans or Tianfengsu and other regulators, the dosage and preparation method can refer to the instructions and consult the agricultural professional technicians) 5000 times liquid pair The tea plant body is evenly sprayed. It should be noted that the above plant growth regulators should not be mixed with alkaline pesticides to avoid decomposition of the medicament. Promoting the selection of growth regulators for new shoots In the growing season of tea, phytochemicals such as gibberellin (also known as 902, gibberellin A, gibberellic acid) and naphthalene acetic acid (also known as NAA) can be used. After the gibberellin is applied to the tea tree, the leaves, twigs, flowers and fruits of the tea tree enter the plant, and the physiological and biochemical processes of the new shoots can be adjusted by changing the biosynthesis, operation and distribution of the tea tree, thereby promoting the new shoots. The role of growth. After using naphthalene acetic acid, the tea tree enters the tea tree through leaves, twig epidermis, seeds, etc., which can enhance the metabolism and photosynthesis of tea trees and cell division and expansion. In the production of tea, naphthalene acetic acid is often used for dip cutting and tea seeding. The regulators that promote the selection of fruit early maturity regulators to promote the ripening of tea tree fruits include ethephon (also known as a test spirit, ethylene phosphorus, etc.). After the application of ethephon in tea trees, the roots, stems, leaves and fruits can enter the tea plant and release ethylene, which can accelerate the ripening of the fruit and the shedding of leaves and fruits. Flexible lift gate is a flexible soft curtain door, inside and outside the two curtains, curtains used between the aluminum beams connected with a vertically movable rail, the roof beams have levels not in the same straight line and hangar large plants in particular be applicable. Flexible lift door installation does not take up interior space in the hole inside. When the fiest move to open the door, and finally superimposed over the hole.
