Greenhouse grapes are divided into four steps

After harvesting in the greenhouse, many fruit farmers do not pay much attention to post-harvest management, and still carry out extensive management. As a result, the yield of the next year's grapes is reduced by 10% to 20% . The experts of miscellaneous fruit pointed out that the fine management of post-harvest grape must master the "four elements" in order to achieve twice the result with half the effort.

 

Combine the actual application of fruit fertilizer

 

After harvesting the fruit, it is necessary to replenish nutrients in time. Restoring the tree potential is the key. After applying the fruit, the fertilizer can play an important regulatory role. After applying the fruit, the fertilizer should be fertilized according to the growth of the plant according to the standard of about 12 kg of quick-acting nitrogen fertilizer per mu . At the same time, 0.3% urea solution should be sprayed and sprayed continuously for 2~3 times to promote the normal growth of the tree potential. If the tree grows vigorously, it is less applied to prevent the new shoots from growing.

 

Cultivating alfalfa

 

If the drought occurs continuously for 15 to 20 days, the irrigation method should be adopted in time to maintain the water holding capacity of the field not less than 60% . In addition, in order to clean up the orchard in a timely manner, it is necessary to timely remove the cut diseased shoots, diseased leaves, diseased fruits, dead branches and sundries out of the garden to deepen or burn them, so as to reduce the source of pests and diseases, and then spray the whole garden. "Guarding the tree general" disinfection and sterilization, preventing the overwintering virus from landing on the tree.

 

Continue to focus on pest control

 

After the fruit is harvested, the fruit trees are susceptible to fungi, and there are downy mildew, black pox, rust, etc. The rainy years are particularly serious. Therefore, after harvesting the grapes, the disease prevention and control should continue. The disease prevention and treatment can be mixed with "new high fat film + fungicide + insecticide" solution to enhance the efficacy. Select pesticides as low-toxic, pollution-free pesticides as possible to avoid long-term residues of pesticides. In addition, it is necessary to prevent pests such as chafers, grape hawk moths, and two-leaf spider mites.

 

Finely trimmed tree

 

It is especially important to carry out careful pruning work after harvesting the grapes and to make a good tree shape. Pruning should first be done with topping and snoring, remove tendrils and thin branches, remove the diseased leaves, reduce nutrient consumption, regulate the nutrient flow of the tree, and promote the full and mature buds. The second is to complete the three branches of the results, the vegetative branches and the renewed branches, and timely deal with the unplanned secondary results. After the fruit tree is trimmed, it is necessary to protect the wound. It can be applied with the oil "callus and anti-corrosion film" to seal the wound in time to prevent the bacteria from infecting the wound, thus protecting the wound from healing.

Guide Ring

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.
