What should I pay attention to when raising seedlings? Who can talk about it?

The seedlings are strong and mature, and the buds are full; Sound root system and many fibrous roots; No pests and diseases. The height of seedlings should meet certain requirements, such as DBH of Populus tomentosa, Populus hybrid and Fraxinus ash seedlings should be above 3 cm, and the height of seedlings should be above 3.5 m; The seedling height of apples, pears, apricots and peaches is more than 1 meter. Try not to use young and weak seedlings and other seedlings.

Master the seedling raising time

In principle, seedlings should be raised during dormancy. Deciduous trees can begin to shed their leaves from autumn to the next spring before the sap begins to flow; Evergreen trees can germinate in rainy season in addition to the above time. In spring, seedlings should be raised early before they begin to sprout. If the buds are open, the survival rate of seedlings will be greatly reduced. In autumn, after the branches and leaves of seedlings stop growing, seedlings are raised. At this time, if we can plant roots in time after the seedlings are raised, we can start growing earlier the next spring.

Master the way out of the nursery.

When raising seedlings, root damage should be reduced as much as possible, and the length of the main lateral roots of seedlings should be kept at least 20 cm to prevent damage to the cortex and bud eyes of seedlings. If the weather is dry, water the soil before you start. For the main roots and lateral roots that are too long and inconvenient to dig up, they can be cut off to avoid pulling out the seedlings, so as not to tear the skin of the seedlings and affect their survival.

Bring soil balls when digging seedlings.

04

When raising seedlings, the root system should pay attention to the diameter of the soil ball on the belt, which can be 6 times to 12 times the diameter of the ground to avoid the root system from losing water when exposed to the air. Bare-rooted seedlings should follow closely; Precious tree species or trees can also be wrapped with straw ropes to prevent soil balls from scattering. After planting, the root system can quickly recover absorption and improve the survival rate. The roots of seedlings that need long-distance transportation should be dipped in mud and covered with plastic sheets or wet straw bags before transportation.
