In order to improve the survival rate of seedling planting, what should we pay attention to when planting in spring?
1、 The planting soil should be fine
Soil provides the basic conditions for the growth of trees, so the quality of soil conditions is related to whether trees can grow healthily. Intensive cultivation shall be carried out for planting seedlings in the nursery. Before planting, thorough deep turning shall be carried out to break large blocks of soil and pull out grass roots. The deep turning depth shall be 40-50 cm, so as to loosen the soil and increase the capacity of water storage and moisture conservation.
2、 Pay attention to the selection of seedlings
1. When observing the roots, select seedlings with developed roots, complete main and lateral roots, less damage and more fibrous roots, which are easy to survive. Seedlings without fibrous roots and hard pulled out are difficult to absorb water after planting and are easy to die. At the same time, pay attention to that the more dry the root is, the better. The seedlings with wet roots and watering are not easy to survive.
2. Do not buy seedlings that have sprouted and long leaves. After planting, the root system recovers slowly, the water and nutrient metabolism is unbalanced, and the survival rate is generally low. Different varieties have different germination time. Seedlings should be purchased according to the planting time.
3. Do not buy discolored, wilted and dried seedlings.
