After mulching garlic irrigation technology, the garlic is covered with a film, and then water is poured. The method is to pour water into the ditch and carry out the drip irrigation. The amount of water must be large, and it is necessary to penetrate the surface. If the watering is not transparent, it must be connected twice . When it comes to emergence, water is poured again to facilitate the emergence of the young shoots, breaking the film and continuing to grow. If there is a bud that does not break the film, attention should be paid to the artificial assisted rupture. During the growth of the seedlings, a long seedling water is poured, and after the "small snow", the wintering water is poured again according to the weather conditions. After the garlic has returned to green in the following year, as the temperature rises, it begins to grow and grow. Before and after the rotten mother's period, water is poured. Mulching garlic into the following year before and after the vernal equinox to the end flaps 3 stalk differentiation stage, it should be timely watering according to weather conditions, particularly in the mid-grown sprouts, growth stage tail Lu, Lu and the like of the shell, must be of proper water, to keep the field Wet state to facilitate the growth of garlic. Stop watering about 5 days before lifting . When nearly put sprouts easily once the soil, soil moisture to distribute Liti sprouts. After mentioning garlic sprouts, garlic into the swelling peak, then pour l times mentioned water sprouts, 5-6 days have been watered 1-3 times, keep the soil moist, in order to facilitate the growth of garlic enlargement.

Guide Ring is a mechanical seal, also known as a guide ring. It is usually made of metal or plastic and used to support and position pistons or rods. Guide Ring has excellent wear resistance and corrosion resistance, which can effectively reduce leakage and friction, thereby extending equipment life. Guide Ring is widely used in the hydraulic, pneumatic, mechanical, and automotive industries as an important mechanical seal.
The classification of Guide Ring can be divided by material, structure, and purpose. According to material classification, Guide Rings are mainly divided into metal Guide Rings and plastic Guide Rings. Metal Guide Rings are usually made of metals such as copper, iron, and stainless steel, which have high strength, wear resistance, and high-temperature resistance; The plastic Guide Ring is usually made of polytetrafluoroethylene (PTFE), nylon, polyimide and other materials, with good corrosion resistance and low friction coefficient.
According to structural classification, Guide Rings are mainly divided into unidirectional Guide Rings and bidirectional Guide Rings. A unidirectional guide ring can only withstand pressure in one direction and is typically used in hydraulic and pneumatic systems; The bidirectional guide ring can withstand bidirectional pressure and is typically used in the mechanical and automotive industries.
According to usage classification, Guide Rings are mainly divided into piston Guide Rings and rod Guide Rings. The piston guide ring is usually used to support and position the piston, preventing friction and leakage between the piston and the cylinder liner; The rod guide ring is used to support and position the rod, preventing friction and leakage between the rod and the seal.
