Generally, the width of the frame is 1- 1.5m, and the surface of the frame is turtle-backed, which is convenient for drainage. Don't cover the soil after sowing. After sowing, cover the grass and water it, watering it 1-2 times a day to keep the soil moist.
Pay attention to moisturizing and reduce direct sunlight, which is beneficial to improve the emergence rate. From August to September, seeds germinate one after another to keep the soil moist and strengthen water management. During germination, cotyledons turn green, so it is necessary to gradually increase the light.
Extended data:
Summer pruning must be based on ventilation and light transmission to enhance the tree potential. Prune cross branches, overlapping branches, diseased branches and dead branches.
The fruiting branches should be shortened: the weak fruiting branches should be updated, and the budding spring shoots should be left with 1-2 branches, and too many weak branches should be removed;
For the long branches, the branches should be thinned according to the distance between the tree crowns, and the short branches should be kept or pulled: for the main branches with too large wounds, sulfur mixture should be applied to the wounds in time to prevent the wounds from being infected with germs and affecting the growth of trees.
