When is the best time to plant chestnut seedlings?

It is best to transplant chestnut seedlings around March, that is, in spring. In spring, the frozen soil thaws and the grass germinates, which is the most suitable time to plant chestnut seedlings. With the increase of temperature, chestnut seedlings will gradually enter the bud state. In addition, it can also be transplanted after beginning of autumn and planted before the land is frozen.

Cultivation techniques of chestnut seedling

1, pruning. Prune chestnut seedlings before transplanting. The purpose of pruning is to transfer nutrients to the roots, so that the survival rate is high. At least one third of the branches should be cut off before transplantation, and the lateral branches should be combed and shaped.

2. dig a hole. The planting hole of chestnut can be dug a little bigger, with a width of 0.8 meters each. To dig deep, chestnut trees can grow to more than ten meters high, so the root system is very developed and the soil grasping ability is strong. After digging holes, about half a month before planting, apply 0.25-40-50 kg of high-efficiency compound fertilizer or phosphate fertilizer to each hole, then add 40-50 kg of manure or decomposed pig dung, mix the fertilizer with the soil and fill the holes.

Step 3 plant. When planting, put the seedlings in the center of the planting hole, gently lift the seedlings while filling the soil, so that the root system of the seedlings extends and is closely connected with the soil, and the planting depth is that the root neck of the seedlings is slightly lower than the ground or the grafted seedlings are flush with the ground. Watering immediately after planting, sealing the soil and covering it with plastic film after water permeates completely, which is beneficial to the survival of seedlings.

4. Post-planting management. Post-planting management of chestnut mainly includes watering, replanting, airing, loosening soil and fertilizing. Water every 6- 10 hour after planting 1 time. Irrigation 1 time before overwintering can improve the cold resistance, check the survival of seedlings in time and replant them in time. Young trees that have survived should be fixed seedlings according to the requirements of plastic seedlings when they sprout in spring.
