In the main producing areas of the northern winter jujube, the planting of leaves from the late September to the beginning of October is the best. This time is the early stage of the jujube tree. The conditions of temperature and humidity are beneficial to the rooting and growth of the seedlings. The soil is warmer and the temperature gradually decreases. The leaves of winter jujube seedlings begin to yellow, the nutrients in the body begin to flow back to the roots, and the nutrient content and moisture content of seedling shoots and seedling roots are the highest. Higher ground temperature and more moist soil after planting are beneficial to the development of roots before winter.
Generally, the roots of winter jujube trees planted in the fall will germinate again, while the winter jujube trees planted in the spring will take root first after germination, or germinate and take roots simultaneously. Planting in autumn should not be late. Planting later in the day is not as good as the survival rate in late spring. The main reason is that the root system of seedlings is not effectively developed, and the seedlings lose water in nearly half a year. Http://Content/667e7b63-4551-44aa-ad45-5f5d005240c4?cType=2
Spacer and Bushing
The Spacers are designed to hold materials a predetermined distance away from the surface they are mounted to, or mount two items a set distance apart. Sizes and materials vary depending on intended use.
The Bushings are used as spacers between pulleys and gears to prevent damage caused by vibration and dynamic loads. The durable bushing material is corrosion resistant.
The
material of Spacer Bushing including carbon steel, Stainless Steel, Aluminum
and Brass. Dimensions are according to custom made. The zinc-plated finish
provides some corrosion resistance.
