Reasonably pruned the short chicken claws that had been fruiting for many years during winter pruning, and only 1/3 of the short fruit branches remained in the whole tree. In order to achieve three sets of branch pruning, there must be at least 15 trees (80 cm long branches) in the current year. The whole tree retains the current year's flowering branches, accounting for 2/3 of the tree's fruit. Can guarantee the output, and can overcome the years. This pruning method has obvious advantages in abnormal climates. Disclaimer: Some articles on this website are transferred from the Internet.

A measuring instrument for quantitatively evaluating the cylindricity of a cylinder by measuring the actual contour of the cylinder using the precise rotation centerline as the reference standard and the precise linear motion guide rail as the reference standard. It can be used to measure cylindrical shape errors (roundness, cylindricity, straightness, and flatness), position errors (coaxiality and verticality), etc.
The cylindricity measuring instrument is mainly used to measure the roundness, cylindricity, straightness, concentricity, coaxiality, flatness, parallelism, perpendicularity, surface waviness, discontinuous surface, etc. of various regular and irregular circular workpieces. It can also perform spectrum analysis, wave height analysis, eccentricity, shaft bending analysis, and runout analysis on workpieces.
This device has excellent cost-effectiveness, full measurement capability, and is easy to learn and use.

The construction of windbreak forests should create conditions to replenish the garden as soon as possible. It can reduce the frost damage and wind disasters of fruit trees, and reduce the evaporation of water in the orchard. Windbreak forests should be established in places perpendicular to the prevailing wind direction, and secondary windbreak forests should be arranged. The secondary windbreak forests should be mixed with shrubs.
Orchard fumigation should pay close attention to the weather forecast at the end of March and early April. If there is frost, you can smoke in the orchard to increase the temperature; or use finely ground ammonium nitrate 20% -30%, sawdust 50% -60%, waste diesel 10 %, 10% fine coal powder is formulated into anti-frost aerosol, which is placed in an iron bucket to ignite the temperature and prevent frost before frosting.
Scientific irrigation requires centralized head irrigation, and irrigated irrigation is forbidden to ensure that the tree body can safely sleep and pass through the winter. Irrigation canal anti-seepage, dredging and drainage, orchard cultivation in time to reduce the harm of salt and alkali to the tree and enhance the ability of the tree to resist low temperature.
Increase the application of organic fertilizer to apply a certain amount of cake fertilizer, reduce the amount of chemical fertilizer application, to avoid growing. The orchard tree is already large and can be plowed after fertilizing on the surface. However, weeds should be controlled. If organic fertilizer, especially cake fertilizer is to be applied in the pit, it must be rotten and mixed with soil to avoid root injury.
To reduce the wounds caused by pruning of pathogens, sterilization protection agent should be applied, and most of the pruning should be retracted. Spray the fungicide such as stone sulfur mixture before wintering to reduce the source of wintering disease.
After appropriate snow protection measures are taken, the snow in the orchard should be scraped away with a scraper to avoid snow damage.
