How many years after the walnut tree is transplanted?

Under normal circumstances, this long walnut takes about 8 years to bear fruit; Grafting will be quick, and it will blossom and bear fruit in 3-5 years.

Post-transplant management:

1, dry season management: from June to September, most of the time the temperature is above 28℃ and the humidity is low, which is the most difficult period to manage. If improper management leads to water shortage in roots and cracking in bark, trees will die. At this time, the management should pay special attention to: first, sun protection, you can cover the crown with a "few" shape in the east and west direction, which can better block the direct light of the sun and protect the leaves from being burned; Second, root irrigation, the water is in the pre-embedded plastic pipe or bamboo tube. This method can avoid pouring "half water" and can be poured thoroughly at one time, which can make the soil dry and wet at ordinary times, or can be poured into the cave outside the crown to increase the humidity of the soil around the trees; Third, erect a triangular bracket on the south side of the tree and install a sprinkler irrigation device that is 1 m higher than the tree to make it foggy as much as possible. Because the south wind blows mostly in summer and autumn, when it is installed in the south, it can often spray water on the tree crown, which keeps the leaves of the trunk moist, increases the humidity around the tree, lowers the temperature and reduces the limited water and nutrient consumption in the tree. "Drip irrigation" can be used when there is no condition, that is, a tripod is set up beside the tree, a water storage bucket is hung on it, a hole is punched in the lower part of the bucket, a plastic pipe is stuck on the hole with silica gel, the other end is sealed after burning, the pipe is spirally wound around the trunk and branches, and holes are punched in the pipe from no direction to dripping as needed, which can also play the role of wetting the trunk and branches and reducing water and nutrient consumption.

2. Management of rainy season: In spring, there is much rain and high temperature in the south, so flood control should be given priority to at this time. Trees often die because their primary buds and leaves and root wounds do not heal. In rainy season, use submersible pump to drain the water in the hole one by one to prevent the trees from being soaked by water.

3. Cold season management: strengthen measures to prevent cold and keep warm. First, wrap it with straw rope to keep warm, which can effectively resist low temperature and cold wind. Second, we should build a simple plastic film greenhouse to improve the temperature and humidity of trees. Third, we should choose to water or spray water on the leaves at noon when the temperature is relatively high.

4. Fertilization after transplanting: Because the trees are seriously damaged, fertilization cannot be applied in the first year, and farmyard manure or foliar fertilizer should be applied in the second year according to the growth of trees.
